Ubuntu Fiesty 2.6.20-5-386; xfsprogs 2.8.18-1
After creating an XFS file system on top of an LVM logical volume:
# mkfs.xfs -b size=4096 -L Videos /dev/video_vg/video_lv -f
meta-data=/dev/video_vg/video_lv isize=256 agcount=32, agsize=4883456 blks
= sectsz=512 attr=0
data = bsize=4096 blocks=156270592, imaxpct=25
= sunit=0 swidth=0 blks, unwritten=1
naming =version 2 bsize=4096
log =internal log bsize=4096 blocks=32768, version=1
= sectsz=512 sunit=0 blks
realtime =none extsz=4096 blocks=0, rtextents=0
I observed:
# xfs_check /dev/video_vg/video_lv
bad format 0 for inode 130 type 0
bad magic number 0 for inode 144
bad magic number 0 for inode 145
allocated inode 130 has 0 link count
And so ran:
# xfs_repair /dev/video_vg/video_lv
