Approx. 1000 CMS files were lost on gdss67 (D1T0 cmsFarm) after a failure of a RAID array. The decision to recreate the array was carried out prematurely before CMS was announced of the file loss. A postmortem has been written http://www.gridpp.ac.uk/wiki/RAL_Tier1_Incident_20100630_Disk_Server_Data_Loss_CMS.
Transtech disk array controller reset itself for an unknown reason, causing mounts on 6 nodes to go read-only, stopping backup of DB redo logs. A reboot of the nodes during a downtime on 5/7/10 fixed the issue.
