Fixed In Version: xfsprogs-3.1.1-11.el6
Doc Type: Bug Fix
Doc Text:
Previously, xfs_repair was unable to properly handle fragmented multiblock version 2 directories (Multiblock dir2 is only enabled with the "-n size=" mkfs.xfs option, where the size is greater than the file system block size). With this update, xfs_repair can operate on fragmented dir2 directories without errors.

Description Eric Sandeen 2013-05-17 14:51:47 UTC
RHS is recommending "-n 8k" for larger dir block size at mkfs time.

However, there are 2 bugs in xfs_repair if those 2 blocks aren't allocated contiguously:

b220548bf2e51f4a573b19b4a8b4b15856bd4a06 xfs_repair: Fix fragmented multiblock dir2 handling in blkmap_getn()

We need to get these backported to RHEL6's xfsprogs to handle this case.

This is tested in xfstests:
