 |
|
almost every week on checking my fs i get
| Code: | 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 0 in dir ino 35644249
missing free index for data block 1 in dir ino 35644249
missing free index for data block 2 in dir ino 35644249
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
| Code: | livecd / # xfs_repair /dev/sda3
Phase 1 - find and verify superblock...
Phase 2 - using internal log
- zero log...
- scan filesystem freespace and inode maps...
- found root inode chunk
Phase 3 - for each AG...
- scan and clear agi unlinked lists...
- process known inodes and perform inode discovery...
- agno = 0
- agno = 1
- agno = 2
- agno = 3
- process newly discovered inodes...
Phase 4 - check for duplicate blocks...
- setting up duplicate extent list...
- clear lost+found (if it exists) ...
- check for inodes claiming duplicate blocks...
- agno = 0
- agno = 1
- agno = 2
- agno = 3
Phase 5 - rebuild AG headers and trees...
- reset superblock...
Phase 6 - check inode connectivity...
- resetting contents of realtime bitmap and summary inodes
- ensuring existence of lost+found directory
- traversing filesystem starting at / ...
free block 16777216 for directory inode 35644249 bad nused
rebuilding directory inode 35644249
free block 16777216 for directory inode 34171444 bad nused
rebuilding directory inode 34171444
free block 16777216 for directory inode 220115 bad nused
rebuilding directory inode 220115
- traversal finished ...
- traversing all unattached subtrees ...
- traversals finished ...
- moving disconnected inodes to lost+found ...
Phase 7 - verify and correct link counts...
done

After repairing, xfs_check reports no more errors. Can anyone tell me why im getting these errors and how bad they are? I always unmounting my devices cleanly ... and i never had any power failure! So is XFS so unstable?

From what I've heard, XFS is pretty reliable, but it certainly gets much less testing than ext3/reiserfs. Could be a hardware problem (bad RAM or a bad HD) or a bug. You might want to try memtest86 and see what smartctl (from sys-apps/smartmontools) has to say about the drive. |

RAM and HDD are faultless ... so no more ideas?

Sounds like a bug in XFS in that case, indeed.
I don't suppose the partition is small enough to get a developer have a look at it? Although I have no idea where one could get in contact with a developer in the first place. |
