Hi,

I'm running a SLES11 SP1 GA based kernel (2.6.32.23) with ext4 filesystem. The e2fsprogs package that's installed on the box is version 1.41.9 (22-Aug-2009). I was wondering if there was a version in compatibility between the filesystem implementation and the tools package, esp. since there have been 5 revisions of the package since 1.41.9

The reason I'm asking the question is my machine recently rebooted after a crash but fsck failed with an error code of 4 and the following message:

"Inodes that were part of a corrupted orphan linked list found"
"UNEXPECTED INCONSISTENCY: RUN fsck MANUALLY"

There were no files being created or deleted at the time of the crash although IOs were probably inflight. So, the inodes being a part of orphaned link list doesn't make sense to me. I don't claim deep knowledge in filesystem internals either. Before I go suspecting a corrupted filesystem, I wanted to make sure I was running the right version of fsck.

Thanks in advance for your help!

P.S. I wasn't sure if this is the right forum to post this question but I couldn't find a e2fsprogs mailing list and linux-ext4 seemed like a good alternative. Sorry, if this is the wrong forum.
