Ok, I have a FREENAS server running with SMB/CIFS. I can access it NO PROBLEMS within windows environment using the folders windows to see my server.
I tried googling CIFS but there's really nothing about exactly why or how I can mount this within Linux or my Desire using CIFS manager. It doesn't work. I don't understand?
In linux I'm trying just mount -t cifs //Serendipity/DataServer /mnt/abc
and this doesn't work..
I get this error message like mount: wrong fs type, bad option ................. etc
Please help, or help me understand how CIFS works, I really don't know why it's so difficult to mount, just like any other mount or NFS.
I posted this here - http://forum.xda-developers.com/showpost.php?p=18647176&postcount=14 - but never got an answer so I'm posting it to its own thread. I would post to the development section but apparently until I clutter up the place with 10 posts I'm considered a drooling idiot.
I was playing around and I noticed that the problem is with s-on I cannot write to /system meaning no superuser etc. So I remembered from way back when I started linux you could mount over a mounted folder. So I made a small file, put ext3 on on it, transferred it to the sdcard and mounted over /system with
mount -t ext3 -o rw,loop /mnt/sdcard/test.dump /system
it worked and then of course I lost all commands (ls, reboot...) in the shell.
Would it be possible to dump /system with "cat /dev/mtd/mtd3 > /mnt/sdcard/system.img", extract it, put it in an ext3 file, mount it as readable over system and just go to town?
Somebody MUST have tried this in the past. Before I go any further can anyone tell me why this wouldn't work and save me a few hours noodling around lol

S-on itself got nothing to do with rooting. It just means you can't flash unsigned images as much as I know.
That system is mounted as ro is also at rooted phones the standard behaviour, you have to remount it as rw, but without root it won't accomplish I think.
Cat is for text files not for binaries or whole partitions, to extract the image use the dd command.
Do you have an /dev/mtd folder? My partitions are at /dev/block and there is no /dev/mtd present.

This issue is that when you remount it as rw you cannot write to it. I want to know if I make my own partitions and mount them after boot if that will work, probably slower but work. This is so lojack I doubt it will work, I just want to know if anyone tried it.
Also "Cat is for text files not for binaries or whole partitions" is wrong, it works fine.

Then it's not rw, because rw stands for read write, but like I said without root...
And no I think no one tried it before, because using an xtc-clip is compared to your solution much less work
But if you want to try it, do it and share your experiences, maybe it helps others
That cat works doesn't mean that it's made for it, you can also hunt for birds with a bazooka
Take a look at cat and dd and choose yourself.

is xtc-clip better? yes, not arguing that. is cat is better then dd? no, I said cat works in this instance the same as dd, the results will be the identical.
I didn't ask this question to argue unrelated linux 101. I'm just going to look into this myself. iow screw you guys, im going home...
Dude, I use Linux too though I'm probably not a guru. I think I understand what you're saying... but if I do, aren't you just talking about editing a copy of /system? How would you mount your edited partition at boot?
Time permitting, I could try a few tricks but I'm not willing to risk bricking my phone though. I'd be stranded without it.

First don't blame others, because of things I wrote.
I never said it couldn't work, I just wanted to show you that there are better ways to do it, cause cat also tries to interpret the file and not only copies it, what could mess up your image in some cases.
Also be aware that if your using the same data and cache partition with both of your systems, it could be easy bricked, if you change to much at your 2. system and remember that there aren't many ways left to get it working again cause your still s-on.
I think he wants to mount it himself every time after boot.
If he can root his 2. system (but all by hand, I think) he maybe can mount his 1. system as rw and also root it, but the chance that something goes wrong is pretty high, even mounting itself could freeze the device, cause the first system is still in memory.
I'm also not even close to be a Linux guru.

Hey-
I've been playing around with the shell, installed bash 3.2 according to this:
forum.xda-developers.com/showthread.php?t=537827
aaaand I was trying to make a link from /system/bin/sh to /sdcard/bash but it didn't take. The reason I want to do that is because I'm experimenting with bash 4.1 and it hasn't quite worked. But when my shell breaks I have to wait for a restore because I can't get write access to the dang /system folder (I guess you need the shell for that).
I know it's not that huge of a deal to have it all in the /system folder once it's how I want it, but I'm going to be playing with other stuff too (bash_profile, etc) and it's a bit of a pain doing the whole trial/error thing. Well, at least with how long it takes. I'm doing trial/error anyway.
So my question is why wouldn't that link work? I know I'd set the link up correctly, tried it several times in case I had a typo. Maybe I just don't understand symlinks like I think I do. I tested also something where I tried to make a link within only the /sdcard folder (always writeable no matter what, thinking that had something to do with it) and just got "operation not permitted". But on my linux box a link between directories is totally cool. Not sure what the difference is. Any help appreciated.
Something else I'm seeing that I really don't understand is that I can create links just not that have to do with my /sdcard partition. I can't even change permissions in /sdcard. From ADB. I run as root:
chmod 0644 filename
and it's as if it accepts the command, but perms stay the same. I did it not as root but it said operation denied. Why if I've got root can't I do some of these operations in /sdcard?

it's about a fat32 part? then will not work
You should post a log
Thanks, I was poking around somewhere and saw that other people have had problems if it's using a windows format. However, I'm burning my brains out trying to figure out how to see what format it uses and how to then change the format. It's the Samsung Galaxy S, and it's an internal memory card. I wouldn't think I could format it from my computer, it's not removable. Or else I'd have found out already using gparted or something (in fact I tried, said 'unallocated' is all). I *perhaps* could use gparted to format it as ext4 or whatever though, but I'm not sure the effect that'll have. I'd have to do some research.
In any case, I'd love to post a log but I'm not sure what log that is that you're referring to, would you mind telling me how to get that?

If you work in adb post console output the same if you made that symlink from phone shell
do not forget to switch to root ("su" command )
by this you get part info
Code:
cat /proc/mtd
or system log here
Code:
adb logcat -d > logcat.txt
- it's saved to adb folder
(do not blame me if you already know these things)
also here is an interesting thread
maybe that part is mounted as read-only ?
make things simple as possible use Root Explorer/ES File Explorer (just tap screen to mount r-w)
Thanks, I liked that article you'd mentioned. Though I also tried the suggestion that was provided when I realized that /sdcard/ is really just /mnt/sdcard/ but still no dice.
I checked those logs, didn't see anything relevant. They're attached so if I just don't know what I'm looking for then someone would see it?
The /sdcard isn't read only, I'm able to write files to it.
I'm thinking really that it's just a windows format, but I still haven't an idea how to actually prove that, nor do I know how to format it for linux. Again- it's not removable. Anyway, if there's something that I need to see in the log, it'd be appreciated if you could point it out to me, thanks.

I think your internal sdcard is vfat-type then try to format as ext4-type
here is a good article on this problem

The SPH-L710 Samsung Stock LJ7 TW 4.1.1 Android doesn't understand/support the change to ext4 external SD card (microSD) without a few things being done.
I'm working this out right now. So far I have manually been able to mount the newly created ext4 partition on the microSD card through adb, and after some chown/chmod I was able to go back to "Settings and Storage" and the "Mount SD Card" picked it up, and I was up and running ext4. But this didn't persist after a restart. So I'm looking into: /etc/vold.fstab MODS to keep it after restart right Now !!
If Some one else already has this perfected please chime in. I'm wanting to do most of the devices in the house this way when I get time because better performance, having a file system with a journal, and getting rid of thins like 4 Gig per file limitations is pretty Sweet in my humble opinion *Grin*
0) Assuming you already have your microSD card formatted ext4. I also happened to label mine extSdCard for the volume label within gparted
1) Can mount with:
mount -w -t ext4 /dev/block/mmcblk1p1 /storage/extSdCard/
2) To get the correct owner and permissions run:
chown root:sdcard_rw /storage/extSdCard
chmod 775 /storage/extSdCard
3) Should make the extSdCard owner/permissons match the regular internal sdcard you can verify this like so:
cd /storage/ && ls -l
drwxrwxr-x root sdcard_rw 2013-01-12 18:16 extSdCard
drwxrwxr-x root sdcard_rw 2013-01-12 17:05 sdcard0
4) After that you can go to the "Settings and Storage" to run "Mount SD" and you will have ext4 extSdCard Show up and it bring up the File System Status !! --> Until you reboot and it goes to crap because I don't have the vold.fstab edit/MOD complete _yet_ ... So, for now a boot script has been put in place to bring our external SD card back online during restart, so the system will acknowledges it, making the world a better place.
Example of how things look file system wise: mount | grep extSdCard
/dev/block/mmcblk1p1 /storage/extSdCard ext4 rw,relatime,user_xattr,barrier=1,data=ordered 0 0
5) Have not been able to resolve the vold.fstab to make this ext4 extSdCard matter fully Legit (in my opinion), but I did manage to make it remount the card on boot, so its online when the system comes up instead of having to manually mount it. Did this by -->
Added the following lines to the very bottom of: /etc/init.qcom.post_fs.sh
## sponix MOD to match with ktoonz kernel for better power management
stop mpdecision
## sponix MOD to mount extSdCard prior to GUI work around to make ext4 function
## read and write extSdCard mount
chown root:sdcard_rw /storage/extSdCard
chmod 775 /storage/extSdCard
mount -w -t ext4 /dev/block/mmcblk1p1 /storage/extSdCard
chown root:sdcard_rw /storage/extSdCard
chmod 775 /storage/extSdCard
## if you want read only extSdCard mount
## mount -r -t ext4 /dev/block/mmcblk1p1 /storage/extSdCard
Still attempting to automate the process so the Stock+root LJ7 can pick up the extSdCard _normally_ without having to do the mount command manually, but so far its kicking my butt. Also this is more a "General, or Question and Answer type Topic" the Kernel(s) obviously support ext4 the system fs uses/requires it *Grin*.. So we might get Our Friendly Neighborhood Moderator to Migrate it to the proper place to help others. Just hoping to get the last few bumps smoothed out, or find someone that already documented the process that I've overlooked *Grin*..
Current Known Issues: If you unmount the card through the "Settings | Storage | Umount SD" or by hand with umount, you will either need to reboot for it to reattach through the /etc/init.qcom.post_fs.sh boot script script addition, or will have to mount it manually if you want to keep the system up and running. Guess you could also probably just run the /etc/init.qcom.post_fs.sh as root from a terminal emulator (or adb).
Still searching for vold.fstab bits of wisdom but that will have to continue next weekend -->

Ha! Sorry. Deleted: Didn't understand that you had it running on boot (can't read properly )
Great idea
Am I really the only one who also thinks this idea is the nuts?
Am I the only one who longs to transform the mess that passes for a filing system on the internal sd using symbolic links into a beautifully organized, encrypted and cloud synced system on my external sd?
Is it just me and a few others that want to be able to achieve the above so that we can move from one ROM to another or recover from a lost phone with the minimum of fuss?
Are we freaks? :cyclops:
Say it isn't so XDA!! :crying:
I'm gonna try this on my international S3 running Null_ Rom 25 JB 4.1.2
PS do you have any idea how the entire ExtSD or just a folder can be enrypted using Cryptonite and automatically mounted at boot time?

Thank you for your prompt reply, yes it is asking a lot I know but I think that it can be done.
Now if you really thought that idea was insane......check this out:
Imagine that we asked every Android app developer to submit the various paths used for their config (and config backup) files to a central database and had the ability to add or own custom paths (which could be added to the central database once approved).
We could build an script/app that would retrieve a list of currently installed apps on your phone then automatically build a symbolically linked file system (and/or backup file system) in the location of your choice that you could either encrypt and/or sync using your current tools or even incorporate this functionality into the app itself along with the ability to choose what was encrypted/backed up and how i.e. either synced to the Cloud or (S)FTP or SMB as either a dd copy or even a cwm flashable zip.
Could I dare hope for a Tasker module or the ability to add custom scripts?
I wish I could do this myself but my coding skills are non existent
Anyway the LUKS manager app won't automatically mount a file system, but I really like it anyways, thank you for pointing me to it!
And on the Ext4 front, the mount command (yes the 1st one ) failed, maybe the op could offer a suggestion. :angel:
BTW is there a place for people to suggest ideas for apps here?
Wait really it wont? I couldve sworn I remembering that it did
But dude....
You need to learn yourself some java and start whipping stuff up
Idk about the whole central database thing, but the rest could definitely be done with root access
I think the main problem with that is the proprietary aspects...i mean even here on XDA where binaries released are supposed to be GPL compliant, many of them arent and its sad because it deteriorates the overall quality of work thats released afterward
This whole thing is just hard work!

You know all the things you need to be creative, learn etc lol
Anyway back to the matter at hand, I have got my ext4 SD card to the stage where I have to manually mount it from within the Settings/Storage as I'm using the international S3 and don't have the init.qcom.post_fs.sh, I think the qcom refers to Qualcomm chipset in US S3's.
As for modifying vold.fstab so we can avoid the above workaround it would seem that maybe thats a dead end as according to a German guy on android-hilfe. de, Vold may have been modified by Samsung to only deadl with exFAT on External SD's.
Looks like I'm not gonna be in Android nirvana for a while :crying:

Got it working ..... kinda
Got an app called ezymount (by ezynow) that automounts my ext4 64GB microSD at boot time.
I have to wait a few seconds for the boot process to complete but it's automatic, am pretty happy!!
Now gotta get symlinks, encryption and cloud synchronization sorted :/
Does anyone know if any scripts are executed (or can be executed) when the SD card is mounted? Of course this would include on boot.
What I am trying to accomplish is that I would like to mount in a second path the fat32 external partition as the system user (with an appropriate umask) so that I can symlink data from the /data/app directory. I don't mind copying the .apk files and just symlinking them individually; I currently have over 5GB of files there, so I know it should really help with saving space. And, this way I can still take advantage of the space as is, rather than losing it all to a directory symlink.
I don't mind resymlinking once in a while after I add/remove some software. I am a long time Linux user (personally and professionally) so a little command line doesn't scare me one bit.
I thought I should mention that I am currently using LRS G Pad, so a solution that works on stock (or stock-like) ROMs is preferred, though I am curious what a custom ROM can buy me in this area also.
Thank you for your help!

Maybe take a look at tasker to initiate a command. I too had hoped to use a Linux command for a different reason, only to find everything to be different enough to be a problem. Tasker will allow the command, but knowing where to put it will be the problem. Writing a script that recognizes "fuse" initiation, outing it in init.d, and then using tasker to initiate the script?
Maybe just tasker, as you can write simple one liners for different tasks(turning things off and on with a simple path).
Doing this from the kernel ramdisk would probably be better.
Please describe exactly how you do this if you figure it out please!
Best regards,
