XFS failure

XFS failure

[Michel]

Hello dear developer,

almost every week on checking my fs i get
*
livecd root # xfs_check /dev/sda3
bad free block nused 2 should be 8 for dir ino 220115 block 16777216
bad free block nused 0 should be 6 for dir ino 34171444 block 16777216
bad free block nvalid/nused 5/-1 for dir ino 35644249 block 16777216

missing free index for data block 3 in dir ino 35644249
missing free index for data block 4 in dir ino 35644249*


when i run xfs_repair ... here is the output

*livecd / # xfs_repair /dev/sda3

After repairing, xfs_check reports no more errors. I always unmounting
my devices cleanly ... and i never had any power failure! But every week
i get the same errors. My HDD is 1 month old and i already tested it for
bad sectors.
