On my phone, /data is being used for cache, then what is /cache and what is it used for?
/data is the data partition storing app data and /cache for app cache. Only Dalvic cache is stored in the /data partition.

Hi
I think that "/cache for app cache" is not exact.
App caches, like thumbnails, browser cache and such, as I know are stored in /data/data subdirs or in sdcard.
/cache "should" be used by market for downloading apps before installing them into /data (I wrote "should" because my /cache is never used...), OTA updates and by recovery like CWM.

Im trying to install some application updates from the market. They will not download because in CATLOG I see "NOT ENOUGH SPACE LEFT" ... the cache folder has 420K available. I tried uninstalling apps I never use but that didnt help.
What can I do to reolved this? I am using SPRINT LOVERS ROM which doesnt support moving the cache to the SD card. ANY ideas would be appreciated....
Update: I erase the dalvik-cache folder and when it re-created, I have 7.4MB of free space.. BUT the program I need to update is a 15MB download ... I removed a few more programs but still not enough space.. What I ended up doing is using ROOT EXPLORER to DELETE the entire contents of the DALVIK CACHE then do into market and it downloaded.
Is there a way I can determine what programs are using the most space in the cache folder? I need to free up space so I would have to unistall more programs but I only want to uninstall large programs (ones that will give me enough free space back)
Have you wiped your cache partition from the recovery? If that and wiping the market's cache doesn't help you'll probably need to uninstall some apps.

Yes I did that.. BUT it rebuilds the cache and its filled up again. is there a utility I can use to see which programs take up the most cache space??
So what this basically means is that you have too many apps installed to be able to put your dalvik cache on the cache partition. By default it's on the data partition, and NOT the cache partition, but some ROMs move it to the cache partition by default. Or maybe you moved it there.
The idea of moving dalvik to the cache partition to free up space for more apps is self defeating. I don't get why anyone does it. The more apps you have, the more space you need for dalvik. So if you've run out of space on /data with dalvik there, you're probably at or will soon pass the point where you have too many apps to fit your dalvik on /cache. If you have few enough apps that you can fit dalvik on /cache, you probably could just leave it on /data anyway.
Basically, either:
1. Keep dalvik and the apps on /data. This may not work for you based on the fact that you've got a lot installed already.
2. Move dalvik to an ext3 partition if you've set one up.
3. Move apps to an ext3 partition, and leave dalvik on /data
4. Move both apps and dalvik to an ext3 partition.
Find the darktremor a2sd thread for details on how to do any of those.
Hi,
I'm using MCR Fr11 (Froyo + Sense) with a2sd+.
Some applications could not be installed in my phone (the application was correctly downloaded then "installation failed" message occured). So I cleaned up the dalvik-cache (rm -r /cache/dalvik-cache/* while in recovery mode).
After that, I managed to install one application (google maps update) but then the problem reappeared with other applications.
I noticed that /cache partition is almost full (3.1MiB left).
I have three questions :
1) I can guess that /system/sd/dalvik-cache is the cache on the SD card used by a2sd+, so was is the purpose of /cache/dalvik-cache ? And why this internal memory cache is located on a very small partition (40MiB) ?
2) Is it safe to delete /cache/dalvik-cache and to create a link in the SD card partition ?
Something like :
Code:
rm -rf /cache/dalvik-cache
mkdir /system/sd/dalvik-cache2
ln -s /system/sd/dalvik-cache2 /cache/dalvik-cache
3) Is there another way to solve the problem ?
Thank you for your help.
I have the same problem, did you found a solution?
You do not have to care about not enough for the cache partition. Just clean cache of market:
Settings>applications>manage applications>all>choose market>clean cache. If this does not help, clean data of market (also under "manage applications"). You can also try to wipe cache in recovery.
I think I have the same problem...
The dalvik-cache is located in the cache partition, and the cache partition is full. Thus no further app can be installed.
Shouldn't the dalvik-cache by default be in the data partition? Does Oxygen move the dalvik-cache to the cache partition? Because I am pretty sure I didn't run any scripts that could have done it.
Can someone point me to instructions how to get it back to the data partition, please?
When flashing a new rom I know you want to clear cache, dalvik, factory reset..
is it recommended to wipe system as well or no?
Some roms will wipe system inside the script itself, but you don't know that without actually taking a look inside...I always wipe everything and then flash.
/data (factory reset)
/system
/cache
Dalvik is part of /data, so it will get wiped too.

thank you sir
I want to install a 4.3 ROM over my 4.2.2 ROM, in the instructions it wants me to do the following:
1. Wipe Data/Factory Reset + Wipe Cache partition. (I have done this before).
2. Mount System + Storage
Format System
Format Data
Format Cache.
(Haven't done this before)
3. Wipe Dalvik Cache (I have done this before)
So my question is what does step 2 do. I am scared it will wipe all my data like pictures audio files etc. that I want to keep.

its alright to format /system, /data & /cache as long as you don't format the /sdcard, i always format /system /data even when i'm just updating the rom .. ^^
Just use factory reset in your custom recovery. It handles data and cache. You don't need to manually wipe system and you don't have to touch dalvik

what will be if I format /boot, /sbl, /xloader ??
Never seen them. I just wipe /data /cache /system and dalvik cache when I do a clean install..

i just do this as well.
I don't recommend wiping xloader
don't know what sbl is
and I always thought /boot is for the boot.img(kernel, i.e. needed to boot device)
