Re: e2fsck: aborted

Google says the error relates to process memory size required for large FSs. The FS here is a 1TB FS, created before I started using largefile and largefile4 for large FSs. When I mount it, some data seems to be lost. Anything I can do other than recover from backup?
I too just experienced this with a 1TB EXT3 filesystem I can't mount. I'm using Fedora GNU/Linux 13 on a 64-bit AMD system with 4GB RAM (around 3.6GiB of RAM is visible according to the system monitor program one runs via System -> About This Computer). I'm running Linux kernel 184.108.40.206-95.fc13.x86_64 (a Fedora kernel package).
I'm using the fsck that came with Fedora 13 (plus all of its updates): $ rpm -qi e2fsprogs Name : e2fsprogs Relocations: (not relocatable) Version : 1.41.10 Vendor: Fedora ProjectRelease : 6.fc13 Build Date: Mon 15 Mar 2010 10:53:30 AM CDT Install Date: Wed 07 Apr 2010 02:17:41 PM CDT Build Host: xb-01.phx2.fedoraproject.org Group : System Environment/Base Source RPM: e2fsprogs-1.41.10-6.fc13.src.rpm

I tried to run $ sudo fsck.ext3 -y -C0 /dev/sdc1(-C0 because I wanted to see how far this would go and -y because I got tired of answering "y"es to all the questions)
fsck aborted itself. I tried looking up this error response and reading e2fsck.config manpage and then I added a config file:
$ cat /etc/e2fsck.conf [scratch_files] numdirs_threshold = 2 directory = /var/cache/e2fsck dirinfo = true icount = truefollowed by re-running the fsck command above. There's over 780GiB free on / (where the scratch directory is mounted), plenty of room to let fsck avoid using RAM.
Both times the fsck process gets to 70% completion and starts a long process of relocating data. That ends with:
[...thousands of lines like the following...] Relocating group 7451's block bitmap from 244154368 to 244154626... Relocating group 7451's inode bitmap from 244154369 to 244154627... Relocating group 7451's inode table from 244154370 to 244154628... Relocating group 7452's block bitmap from 244187136 to 244187394... Relocating group 7452's inode bitmap from 244187137 to 244187395... Relocating group 7452's inode table from 244187138 to 244187396... e2fsck: aborted and I'm still left with a volume I can't mount.I was surprised that even though I specified I wanted the fsck to use the scratch directory the files in the scratch directory aren't very large and all of my remaining RAM is still used by fsck. It's as if using the scratch directory only made the process run slower but didn't change anything to do with (what I'm reading) is the main problem--not enough RAM to hold the data fsck needs while it runs.
I can't add more RAM to the system, 4GB is its max.Has there been any improvement on doing fsck on large volumes (where "large" means larger than what fsck can work with in available system RAM)? I'd gladly trade repair time and disk space for an fsck that worked. Any ideas on how I can get fsck to run and actually fix this volume would be welcome.
