Please can I have soome assistance with a disk becoming disabled? Unfortunately I have rebooted since it happened so am probably missing log files. Nothing has changed; the server was sitting idle and it suddenly happened. It had been up for nearly a month.

 

Obviously I want to avoid any data loss.

 

I have no idea what I'm doing beyond basic setup so I'd appreciate some explicit guidance.

 

Thanks!

 

Edit: I've tried the repair in maintenance mode and it says:

 

Phase 1 - find and verify superblock...
        - block cache size set to 1117984 entries
Phase 2 - using internal log
        - zero log...
zero_log: head block 118210 tail block 118206
ERROR: The filesystem has valuable metadata changes in a log which needs to
be replayed.  Mount the filesystem to replay the log, and unmount it before
re-running xfs_repair.  If you are unable to mount the filesystem, then use
the -L option to destroy the log and attempt a repair.
Note that destroying the log may cause corruption -- please attempt a mount
of the filesystem before doing this.

 

I have no idea what this means.

Updated information

I've been playing around with it - perhaps foolishly. I can now see the contents of the drive and it appears in the array, without a specific error message, but it still has a red X next to it. Could someone advise what I need to do next?

Disk looks healthy, if the emulated disk is mounting and contents look correct you can rebuild on top, it may be a good idea to replace cables first to rule that out.

Thank you. It is rebuilding at the moment.

As a further bit of information, I updated to the latest build about two days after this event, and upon reboot, a different disk was disabled, so I repeated the process.

 

The server has been stable for in excess of a year, so it is troubling as to why I might suddently be seeing this.

 

I purchased another LSI 9211 and a breakout cable (as a spare) as I don't want this suddenly failing over the holiday period!
