I am using rooted LG P500 running stock 2.3.3. Recently I partitioned my SD card using ROMManager in to three partitions (swap, ext and usb storage). I checked with Mini Partition Tool and understood that the sd-ext type is ext3. Link2SD created mount script and linked apps perfectly, releasing loads of space in memory.
To try an unofficial CM10 ROM, I backed up using ROMManager (NAndroid) and installed the unofficial CM10 ROM. While using CM10, I wiped sd-ext partition and linked few apps with belief that backup is done. Since I was unhappy with the CM10 ROM I decided to restore the backup and while doing so only I observed that my sd-ext partition contents were not backed up.
Thinking that I might not have backed up properly, I tried again to back up in restored backup of stock 2.3.3 and observed a message:
"Could not mount sd-ext. sd-ext backup may not be supported on this device. Skipping backup of sd-ext"
Had if I had noticed this message, I would not have installed the CM10 ROM at all.
Question: How can I make ROMManager to backup sd-ext partitions as well? I guess just because it was unable to mount, it just skipped sd-ext backup. When Link2SD was able to mount, what is stopping ROMManager to mount it and how can I fix it?
- I tried this with ClockworkMod Recovery version 18.104.22.168 and ROMManager version is 22.214.171.124
- I have seen the question "Ext4 partition clockworkmod recovery backup" and this question differs because the partition used is ext3 and was created by ROMMananger itself.
I have seen this modaco forum thread and it just only helped me to come to a assumption that my present recovery version 126.96.36.199 does not support it. I will be glad to confirm it either from any authoritative source or burst the myth if some other user successfully backed up (either with 188.8.131.52) sd-ext.
When I attempted to use "mount and storage -> mount /sd-ext" option in CWM recovery console, I just get "Error mounting /sd-ext!" message.
