Root Cyanogen 7 low disk space

[CoastalDroid]

I moved my HTC Desire GSM from a stock HTC ROM to the Revoultion ROM A2SD+ in order to get rid of my low disk space issue, and with regard to never having to worry about newly installed apps, all was fantastic. I was not happy however with some of the lagging (as previously seen with Sense ROMs), therefore I changed to Cyanogenmod 7 to get a gain in speed. This has worked great, however I now have the low disk space issue again !?! I have ensured that all qualifying apps have been moved to SD, but "internal storage" showing as a measly 13 Mb (of 148Mb).

What can I do to take full advantage of my new ROM?

Thanks.

Did you partition your sd and enable a2sd?
Some do it by default but if you don't have the ex3/4 partition then I don't think it will once you get the partition.

I partitioned my SD with Gparted (and created an ext4 partition) before I loaded the original (Revolution) ROM. Before I loaded the new CM7 ROM, I performed a wipe of data, cache and dalvik. Did I miss a step?

Do I have to manually "enable a2sd" with CM7?

There is no A2sd with CM7. You have to flash one of the scripts mentioned in the CM7 thread, or use Simple 2 EXT (2sE) from the market (although scripts are better IMHO).

Never dawned on me that a ROM with such a good rep would not have some form of SD app management...

I took your advice SURoot and opted for a script (Data2SD)

All works a charm now, cheers SURoot. Loving CM7.

One aspect I noticed though... after a phone restart, you must leave the phone for a healthy period of time to 'settle' down. Otherwise accessing certain apps (such as email in my case) too early will bring a succession of app crashes, requiring another restart.

The thing is that many android phones have more internal storage than the Desire. CM7 is available for many phones, and not all of them need an a2sd script. So with CM7 it's more an add-on for those handsets that need it, whereas it's a built-in part of many Desire-specific ROMs.

 

[SUroot]

And a2sd or data2sd isn't the only option. There are hboots too.

I have come back to this thread as I have just had a catastrophe with my Desire running CM7 with data2sd -- SD card has become unreadable (see post http://androidforums.com/desire-support-troubleshooting/627018-sd-card-requires-formatting.html).

I might as well take this opportunity to set my phone up differently. The biggest issue I had with my phone on CM7 with data2sd was lag, especially with everyday apps eg. such as dialler, with screen not coming back into view for up to 5 seconds to allow call hangup!

Can anyone recommend a suitable ROM which will allow me to run everyday apps from memory (dialler, sms, email client , browser etc) and selected apps from SD?

I understand the phone is an old model, but I feel there is plenty of life in the old girl yet, with a suitable setup.

Many thanks.

Well CM7 itself can do that, if you just use a2sd, and especially if you use a custom hboot to gain more internal space. But if you want to avoid that the best bet is a small ROM plus a custom hboot. dGB is the ultimate in this respect - the ROM itself is so small that you can fit it in 60MB, and use a custom hboot that gives you > 370 MB of internal space. I've been using this ROM myself for the last year.

You need S-Off for the custom hboot, but we'll be happy to talk you through doing that if you haven't already.

Thanks for the offer of assistance Hadron. This is all confusing as hell . At the top of my original post you will see that I was still having issues with memory after I applied CM7. I was informed that "There is no A2sd with CM7" whereas the CM7 wiki Apps2SD - CyanogenMod Wiki indicates that "CM 6+ takes the native Google method, and improves upon it". Hence my previous question: "Do I have to manually "enable a2sd" with CM7?"

If I can get CM7 to work with some form of SD caching, then I will. Alternatively I am happy to use an alternative ROM which allows me use everyday apps (dialler, sms, email etc) from memory and pick and choose apps to run from SD.

I currently have alpharev/CWM on my phone.

Please advise on:
- the next step, if I go with CM7 (and how to 'enable' a2sd);
- if I chose to go with an alternative ROM such as dGB, can I just implement it from SD via CWM? Or is there more to it?

Many thanks in advance for your help.

The confusion is that there are 2 types of "a2sd":

* the native Google one, which is the "move to sd" item in the applications menu

* the version using an ext partition

CM7 comes with the first, which is part of the Android OS since Froyo (i.e. CM6 onwards), but you have to add the second. When I used CM7 I added the DarkTremor script (a2dd, not data2sd) but many use the app Simple2Ext instead.

 

[Hadron]

You can simply flash another ROM via CWM, but a custom hboot requires S-Off and flashing via fastboot.

I'd rather not flash again -- first time I watched through my fingers !!

I think I still had issues originally with CM7 when I applied the native one, therefore will opt for the latter.

Next confusing points:
- when a ROM indicates that it comes with a2sd ... does this mean it applies the native variation?
- can I run a a2sd script regardless, before applying any ROM?

 

[nicka3200]

When a ROM says it comes with a2sd it usually means the type that uses an ext partition.

First step - partition sd card with Gparted (back it up first) See http://androidforums.com/desire-all-things-root/220627-faq-apps2sd-updated-17-02-11-a.html and Using Gparted tutorial - YouTube and http://androidforums.com/desire-all...mware-player-updateded-8th-august-2011-a.html

Second step - install s2e from googleplay or flash a script (Dark Tremor) via recovery.

 

[Hadron]

Yeah, any ROM from Froyo onwards includes the native a2sd, so nobody even mentions that - it's a given.

hi CD,
i went the s-off + hboot route and it was cool - no worries at all - seems scary i know, but is very easy

good luck
cheers

My 2c: Was the Data2SD script not causing the OP's lag because it was putting all data on the SD rather than just the apps? I know this can cause slow downs depending on the SD card class.

 

[Hadron]

Very possibly - I've avoided using it for that reason.

I am using CM7 on a Desire and what worked for me was
Partitioning 1Gb of my SDCard
Installing S2e and using recommended settings.
Now have 72Mb free instead of 12Mb.
