Root Getting my head around a2sd

I am running stock hboot and evervolv JellyBean ROM. Ran the A2SD commands in terminal after install with a 1GB EXT3 partition. All was really great. I know this ROM is pre-alpha but it's so slick I love it. Tonight after trying to install another app I got the dreaded low storage message????

Quick System Info reports:
SD card Free 3.7GB
A2SD Free 764Mb
Internal Storage Free 32Mb
System Storage Free 5Mb
System Cache Free 39Mb

I've rounded those numbers to save typing.

A2SD is clearly working but why am I hitting low storage space already?
 
A2sd doesn't move everything. App data remains internal, as do some app components.

Did you move the dalvik cache? If it's the same commands as DarkTremor then "a2sd cachesd".

I thought about trying that one tonight - would have been my first ROM flash in 6 months!
 
I followed this:

1. After installing the ROM, open up terminal in the app drawer and type

su
a2sd install
(Y)es to moving Dalvik cache to sd-ext
(N)o to moving app-data to sd-ext
(Y)es to reboot

We feel the above setup has the best performance, your applications will go to /sd-ext together with dalvik cache but the app-data stays on the internal memory
 
Hmm, that's what I'd have done too.

So the question is has it worked (is dalvik on /sdext), and if so have you just got apps with large libraries or are they using a lot of data? If you look at them sorted by size, and also see which ones are using a lot of data space, that may give some clues.
 
The utility you used to partition the card should be able to tell you. If you use 4Ext Touch recovery that can also show you the partition table (the 4Ext Recovery Control app can do this too).
 
Hmm, don't know some of those, but 19MB for Google Search? How much of that is data/cache? On mine (Gingerbread) that app is using 1.3 MB.
 
It surprised me that it was top of the list. Here are the stats

Version 2.0.5.443668
Total 18.84Mb
App 18.65Mb
Data 195Kb
Cache 1.01Mb
 
App 18MB?? If I had time tonight I'd be tempted to flash that ROM myself to see - that's a huge increase in size over the GB version!. Though if it is app size, and the app is downloaded rather than system, the apk should be on sd-ext, so as long as it's the apk which is huge rather than some other app component it shouldn't be using much internal space.
