Re: [CentOS] Help. Failed event on md1

Quoting Fajar Priyanto fajarpri@cbn.net.id:

I apologize. I guess the panic hit me :):)

Fortunately, after I remove the device: mdadm /dev/md1 -r /dev/sdb2

And then re-added it: mdadm /dev/md1 -a /dev/sdb2

It's rebuilding again. Pheew.. my first failed RAID event.

This can happen sometimes when machine crashes. However, I would still recheck log files to see if there were any warrnings/errors on /dev/sdb (these are usually the very first signs that disk might fail soon). Keep an eye on that drive, and recheck logs (/var/log/messages) from time to time. If you see any errors reported on it, replace it immediattely.
