Murphy and disks

It must be release time again and Murphy is shakes his ugly head. This weekend, beastie (running the danish half of lost a disk. This shouldn’t be a problem in itself, and the hotspare disk took over, so about a day after all was well again. Yesterday, I changed the disk and marked the new disk as the new hotspare. So far so good.

Just after I left the office, beastie rebooted spontaneously. Now the new hotspare disk suddenly turned up as a separate disk and the RAID set was recognized under a new device name and thus could not be found at it’s original location and the boot bailed out. And now Murphy really does his trick. After rectifying this in the RAID BIOS so the new hotspare really was a hotspare and not a disk, beastie booted and all seemed well…until…the RAID set had lost its disklabel and filesystem. Now there’s not much else to do then sync 0.5Tb data.
