Two disabled disks, need help with diagnosis

Disks were already disabled at array start so we can't see what happened, there's a 1TB disk causing constant errors, I assume that is the missing disabled disk15? Check/replace cables for that disk and post new diags after array start.

Hi JorgeB,

 

Happy Holidays and new year is just around the corner, appreciate the help so far.

 

I've attached the new diagnostics data. 

 

The machine was restarted a few times and managed to get a rebuild going but then the server becomes unresponsive after a few hours. Now the array is seeing lots of errors on the disks.

 

Not sure what the cause is, help will be appreciated.

So far only see this:

 

Dec 27 07:27:24 HTPC-Vault kernel: XFS (md15p1): Unmount and run xfs_repair

 

Check filesystem on disk15, also enable the mirror to flash drive option in the syslog server, and post that if it crashes again.

The file check on disk 15 was this output:

Not sure what the above means. The drive is powered up and the cage it's in is powered on.

 

syslogs are attached.

Run it again without -n or nothing will be done.

disk check done again without the -n, see bwlo:

Should be fixed now.

All fine now, thank you for the help. I'll have to read up more on this and it's the first time using this command. Appreciate the learning experience.

 

Thanks!
