Sorry for the delayed reply on this. After discussions with Eric about
the endian fixes missing from e2fsck, I also looked back at the uninit
groups patches and did a line-by-line comparison to see if anything was
missing. Sure enough, there are a few checks, and all of the regression
tests are missing.
The missing code is attached here as a patch, and I've uploaded the full
set of CFS patches (against 1.40.5, which I wasn't previously able to
host anywhere) to http://downloads.lustre.org/people/adilger/ in case you
are missing any of the test cases:
tests/f_uninit_bad_free_inodes
tests/f_uninit_blk_used_not_set
tests/f_uninit_checksum_bad
tests/f_uninit_disable
tests/f_uninit_enable
tests/f_uninit_inode_past_unused
tests/f_uninit_last_uninit
tests/f_uninit_set_inode_not_set
I verified all of these tests pass with the code currently on the "next"
branch plus this patch. All of the f_extents_* patches currently fail,
but that is a different story (not sure I'll have time to look at those
before I go on vacation).
========================================================================
Add a check for the UNINIT_BLOCKS flag set in the last group. The kernel
patch doesn't handle this gracefully, because it assumes there are a full
set of blocks in each group marked UNINIT_BLOCKS. The kernel should be
fixed up, but in the meantime this avoids hitting the problem, and is
more consistent with lazy_bg not marking the last group UNINIT.
Un-static the ext2fs_group_desc_csum() so that it could be
used in parse_gd_csum(). The other alternative was to hack around and
have ext2fs_group_desc_csum_set() set the calculated checksum value in
the filesystem, extract it back into "val" and then have the caller
save it back into the filesystem... Yuck.
Add the ability to have debugfs calculate the correct group checksum.
This is used in the last_uninit testcase, and this requires re-adding the
call to ext2fs_group_desc_csum_set() in e2fsck's check_super_block(),
otherwise it doesn't update the checksums after having "fixed" these
errors and restarting e2fsck would cause the same problems to be hit
each time. It is now conditional upon having fixed some problem instead
of always being done, so this automatically makes it safe for read-only
filesystems, etc.
Split the m_lazy testcase into two tests - one that has resize enabled,
and one that does not. There were previously problems with lazy+resize
because the resize feature consumed blocks in some of the groups.
