ruh-roh! Write Errors on 3 different disk during rebuild - and all files missing

Featured Replies

Hi guys,

 

I seem to be having major issues with the rebuild of a new disk.

 

It was in the middle of a disk replace (#1) when the power got cut off.

 

I restarted the server (and disk replace #2) and now I woke up this morning to (see attached picture)...

 

It looks like are write errors 134774640 and counting) on disk 2,3 & 5 and all files on these disks are missing.

 

I don't want to halt the current rebuild but is the data on these lost? Or can I wait for the disk replace to complete and rebuild parity so I can get my files back?

 

here is a snippet of the log

 

Jun 23 07:25:37 Tower2 kernel: md: disk2 read error

Jun 23 07:25:37 Tower2 kernel: handle_stripe read error: 65088296/2, count: 1

Jun 23 07:25:37 Tower2 kernel: md: disk5 read error

Jun 23 07:25:37 Tower2 kernel: handle_stripe read error: 65088296/5, count: 1

Jun 23 07:25:37 Tower2 kernel: md: disk1 read error

Jun 23 07:25:37 Tower2 kernel: handle_stripe read error: 65088304/1, count: 1

 

 

 

Help/suggestions would be appreciated!

OK I Stopped the Rebuild at 31%

 

Rebooted and Started (w/o rebuild)

 

I am going to give it another go but if I get more errors like above - does anyone have any steps to solve it?

 

 

I didn't look at the syslog. but inadequate PSU is the very first thing that comes to mind when you have multiple errors on multiple drives at the same time during a rebuild.

 

There are always other  reasons like a bad card or disk.. but power is often overlooked.

Ok thanks. Its a fairly new PSU but I will take a look.

 

The second time completed and now it looks like both the Parity and #2 (no files again) have errors (different drives that previous attempts!) so maybe it is the power.

 

It is currently attempting to correct errors by writing corrected parity. hope i get no errors and my files back.
