On friday april 7 one of our backup raid controllers lost two of its four disks. We were unable to repair the damage with the remaining 2 disks in a sufficient way and decided to start over with the backups for the affected hosts. Due to the crash there are no backups available from april 7 and earlier for the following hosts:
bestla bergelmir bianca caliban callirrhoe carpo eirene fairydust johnson pizarro sanguin
The original data on these hosts and the backups on other hosts were not affected by this. New backups for the affected hosts are running since april 8.
