Follow up on the drive swaps on sci-sattx
Start= Jun 8th, 4pm
End= Jun 8th, 8:50pm
Issue= sci-sattx was in read only mode after swapping 2 disk in a row
After swaping one disk on sci-sattx, we received many warning messages (>300) about bad sectors found on disk #16 (we now suppose that this was a spare drive). Since disk #2 rebuilding process was complete we changed the drive. Between the removal and the insertion (5 minutes), the machine rebooted unexpectedly.
After that, the raid drive was in read only mode and drive #16 unconfigured (ie not used in the raid setting). The side effect was that SPADE stop the tapping on both sattx1 (2 drives) and sattx2 (2 drives)
After talking over skype with Cindy M. then Tex and Steve B., we decided that the course of action should be (on both machines):
- shutdown spade (from web interface)
- umount /mnt/data
- run fsck -y /dev/sda
- if checkdisk is successfull and the drive is not in read only mode any mode, mount -a
- start jboss
I lost some time because I was remotely connected to the Icecube network via ssp-access and my session was terminated during checkdisk. It appears that it was in fact terminated after.
