Subject: e2fsck running extremely slowly
Date: Sun, 21 Jul 2013 15:45:20 -0700 [thread overview]
Message-ID: <51EC6480.6000200@zytor.com> (raw)
I have a large filesystem (14 TB) which suffered a RAID failure which
seems to have corrupted some inodes. Unfortunately as a result there
are now a number of inodes with "false extents" which result in a very
large number of multiply claimed blocks.
I have tried to run e2fsck on this filesystem, and it gets as far as
phase 1D, at which point it starts running at a glacial pace. After 48
hours -- most of it sitting at 100% CPU executing no system calls at all
-- it claims to have processed a single file out of almost 10000.
Anything I can do (to rescue the filesystem or try to debug the problem)
other than "wipe and start over"?
I believe this is e2fsck 1.42.3 from Fedora 17.
