SDSPLIT repartition your SDcard on phone (w/o a PC)
- Thread starter MartinFick
- Start date
Thank you for this! I used it a while back. I'm now seeing some random stale NFS file handlers on my ext2 partition. I tried to delete the partition and recreate it using another partition program, but I believe the errors are still there. It seems to have occurred during upgrading/updating various apps. I'm using a 4gb class 6 knockoff sd. (I did order a Sandisk this morning - it may help avoid these in the future).
Is there any way to run a fix for this on the ext2 partition directly on the android?
I'm more of a windows sys admin so not that experienced *yet* on Linux/Android.
TIA!

Please, include some logs or at least your command line. Invalid argument means you gave it an illegal command line, post it if you want help.
This does not sound like an error with your partition. It is strange indeed, I would search other threads, perhaps others have seen such problems. Are you even using NFS at all? Stale NFS files handles usually happen when you have a file open over NFS and someone deletes the file on the NFS server. Really, this likely has nothing to do with your EXT2 partition.
You forgot the -fs:
# /data/sdsplit -nc -fs 7500M
...no need to repeat the previous steps.
$ su
# cd /data
# wget http://64.105.21.209/bin/lib/droid/sdsplit
at this step I get an error:"wget:server returned error: HTTP/1.1 404 Not Found"
Help!!
# cd /data
# wget http://64.105.21.209/bin/lib/droid/sdsplit
at this step I get an error:"wget:server returned error: HTTP/1.1 404 Not Found"

Hmm, I just clicked on your link and it worked fine (from my phone).
Perhaps you are using a proxy server that has problems? If you can download it some other way, go ahead.
Ok this is first time it did all this so it looks correct but then I get a small error at the end is this normal or ok?

I believe that happens if you had a blank FAT partition to start with... I should fix that in the next update. I think you are safe to ignore it (if you indeed had a blank card to start with)
If you chose 4B) Restore your data from your PC. (Again, beyond the scope of this HowTo).
8) You're done! You should have two partitions now on your sdcard. The FAT one mounted at /sdcard and the EXT2 one mounted at /system/sd.
If your run into any serious problems, try to send me the file /data/sdsplit.log if you can get it off your phone.
ok..I just finished step number 8..this one and now I am getting a notification saying the sd is damaged..

Fair enough, yes it was freshly partitioned so it was a blank fat 32 8gb sd card, looks like its worked this time thank you for your help!
Now im off to reinstall the apps to sd card app in the market, do you have any experience using this app or how to make it work properly?

Adding JF1.5 warning
I've added a warning to the HowTo and First Post about JF 1.5. I am baffled, please, if you have succeeded with the JF 1.5 build (and rebooted), make sure that you leave a success post mentioning the build you use. Thanks!

Moving ChangeLog here since there is no space left in first post.
Planned:
* Force uppercase for size units
ChangeLog:
v1.7 2009-05-10 (usability improvements)
* Prompt on startup (confirm requested actions), use -f to override.
* Log invocation string to sdsplit.log
* Removed error when sdcard is empty
* If no ext2.ko is found output a message instead of an error.
v1.6 2009-05-02 (minor unimportant bug fix)
* Better mke2fs validity/availability checking
v1.5 2009-04-30 (minor workaround)
* Hardcoded theficks.name IP for downloads (workaround for apparent DNS problems which still seem to sometimes persist)
v1.4 2009-04-29 (Feature additions, large FAT partitions!!!, and robustness improvements)
* Added automatic logging to /data/sdsplit.log
* Create /data/local/bin if needed when downloading exes (to simply HowTo)
* Wipe first 4 blocks of sdcard before using fdisk to avoid partition table re-read problems.
* Test capability of mkdosfs and download better one if needed (to handle partitions greater than 2GB!)
* No longer backup partition table, no longer useful since we wipe part of the FS also.
* Mount partitions after creating them, even when not restoring data.
* Fixed free space reporting
* Worked around 'bad address' problem. (EDIT: apparently not, see v1.5)
V1.3 2009-04-6 (robustness improvement)
* Added a check to see if /system/sd is already mounted
* Added a --forceumount option to continue despite /system/sd being mounted (by unmounting it)
V1.2 2009-04-5 (feature improvement only)
* Added automated mke2fs download and intallation if executable is not found.
V1.1 2009-04-3 (bug fixes, do not use 1.0)
* Fixes mount point link creation (/system/sd)
* Load ext2.ko module during script so that a reboot is not required to see the new ext2 partition (/system/sd)
* Moved partition backup to a non reboot volatile directory (/data/local/tmp)
* Tried to improve help with respect to specifying partition sizes
V1.0 2009-04-2
* Original Release

Just did it on Jf1.5 build. It gave me insmod ext2 error and restoring error. The first I just ignored cause ext2 should exists in Jf build, and I finished the restoring myself and it works fine now.
Thanks for the good work!
