Unmountable disk present after powercut


Recommended Posts

Hi all, I've got the following error on the Main tab for one of my disks, but then another disk is showing as "Device is Disabled".

This is all after a powercut I had yesterday.

 

Attached is my diagnostics after starting the array

 

Any idea what I need to do to resolve this? My disk/hardware knowledge is not great

Don't think there would be much point in rebuilding disk4, since disk1 is corrupt a rebuilt disk4 would also be corrupt, best bet is to do a new config to re-enable disk4, as for disk1 you can run a filesystem check but most likely there won't be much of use there.

Ok

So replace disk1 then? 

How do i do a new config to disk4? Is there a link on the wiki anywhere?

No, check filesystem.

 

-Tools -> New Config -> Retain current configuration: All -> Apply

 

Then start array to begin a parity sync (or check parity is already valid before array start and then run a correcting check).

 

Filesystem check output:


Phase 1 - find and verify superblock...
Phase 2 - using internal log
        - zero log...
ALERT: The filesystem has valuable metadata changes in a log which is being
ignored because the -n option was used.  Expect spurious inconsistencies
which may be resolved by first mounting the filesystem to replay the log.
        - scan filesystem freespace and inode maps...
        - found root inode chunk
Phase 3 - for each AG...
        - scan (but don't 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...
        - check for inodes claiming duplicate blocks...
        - agno = 0
        - agno = 1
        - agno = 2
        - agno = 3
No modify flag set, skipping phase 5
Phase 6 - check inode connectivity...
        - traversing filesystem ...
        - traversal finished ...
        - moving disconnected inodes to lost+found ...
Phase 7 - verify link counts...
No modify flag set, skipping filesystem flush and exiting.

And Parity sync is now running

Done, yeah it was XFS

 

I had to use the `-L` option as it was complaining

 


Phase 1 - find and verify superblock...
Phase 2 - using internal log
        - zero log...
ALERT: The filesystem has valuable metadata changes in a log which is being
destroyed because the -L option was used.
        - 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...

        - agno = 0
        - agno = 3
Phase 5 - rebuild AG headers and trees...
        - reset superblock...
Phase 6 - check inode connectivity...
        - resetting contents of realtime bitmap and summary inodes
        - traversing filesystem ...
        - traversal finished ...
        - moving disconnected inodes to lost+found ...
Phase 7 - verify and correct link counts...
Maximum metadata LSN (213:549485) is ahead of log (1:2).
Format log to cycle 216.
done
