Wednesday, 28th of May 08:00: /home/t1home and /home/uibkvant will be unavailable during a firmware upgrade of those file systems.
This downtime will probably last for a couple of hours.

Update 28th of May:

10:30: File system is now being unmounted on all compute nodes, and will be unavailable until upgrade is complete.
11:30: The firmware upgrade is now started.
12:30: One disk controller failed during the upgrade and has to be replaced. We are expecting the replacements arrival later today. The downtime will therefore be extended.
16:30: /home/uibkvant is now up again. /home/t1home have to wait for the new controller to arrive.
01:30: Will continue tomorrow.

Update 29th of May:

09:00: We continue the work from yesterday.
18:00: Controllers have been revived. Working on recovering data disks.
00:00: Will continue tomorrow. Seems like no data has to be restored from backup.

Update 30th of May:

09:00: We continue with recovering data disks.
14:00: Running file system checks to vertify data. If data verification is successfull /home/t1home will be up again soon.
14:50: Verification was successfull. /home/t1home is now mounted on all compute nodes.
