Subject: Problem after removing SATA II disc without unmounting
Date: Mon, 27 Nov 2006 16:07:28 +0100 [thread overview]
Message-ID: <456AFF30.2060904@weberhofer.at> (raw)
Hello!
I have a problem with an hard-disk which has been removed from a SATA II slot without being unmounted. After inserting the disk, a mount attempt results in:
server:~ # mount /backup/
mount: /dev/sdb1: can't read superblock
****************************************
xfs_check /dev/sdb1 does not show any error
****************************************
xfs_repair shows:
server:~ # xfs_repair /dev/sdb1
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
- agno = 4
- agno = 5
- agno = 6
- agno = 7
- agno = 8
- agno = 9
- agno = 10
- agno = 11
- agno = 12
- agno = 13
- agno = 14
- agno = 15
- process newly discovered inodes...
Phase 4 - check for duplicate blocks...
- setting up duplicate extent list...
- clear lost+found (if it exists) ...
- clearing existing "lost+found" inode
- deleting existing "lost+found" entry
- check for inodes claiming duplicate blocks...
- agno = 0
- agno = 1
- agno = 2
- agno = 3
- agno = 4
- agno = 5
- agno = 6
- agno = 7
- agno = 8
- agno = 9
- agno = 10
- agno = 11
- agno = 12
- agno = 13
- agno = 14
- agno = 15
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 / ...
- traversal finished ...
- traversing all unattached subtrees ...
- traversals finished ...
- moving disconnected inodes to lost+found ...
Phase 7 - verify and correct link counts...
done

in /var/log/message I can see:

I have Opensuse with kernel kernel-default-2.6.16.21-0.25 running. Do you have any ideas/suggestions?
Best regards,
