Comments

[Andreas Dilger]

Old lfsck is no longer supported.

[Jian Yu]

I could reproduce the issue on single RHEL5/x86_64 test node against the latest Lustre b1_8 build (http://newbuild.whamcloud.com/job/lustre-b1_8/120/) with e2fsprogs-1.41.90.wc3-0redhat. The same test passed on master branch. I'll investigate more.
