Failing disk in caligula

caligula will be brought down sometime this evening for disk replacement. The subsequent downtime will take several minutes, and will bring down all websites hosted on caligula, as well as e-mail. However, no e-mail will be lost in the transition.

One of the disks in caligula’s RAID1 array is failing. Replacing it will actually only incur a few minutes downtime and with no data loss. However, the server’s performance will slow for a few hours after the downtime as the disk is re-added to the array.

More precise information will be added as it becomes available.

Update Jul 08, 2009 3:44 PM: Downtime is over. Failed disk has been replaced and the array is rebuilding.

Update Jul 09, 2009 11:22 AM: Array has finished rebuilding, and operations back to normal.
