List,
A few weeks ago I created a 1-disk RAID1 volume and migrated data from a
decaying RAID1 md0 device.
Last night I finally got the second device in the mail and added this to the
existing RAID1 setup and balanced the volume.
I use this setup for Time Machine backups using afpd, so I noticed this
morning that a backup had failed and decided to poke around to find out why.
Well, I probably should have looked at the logs first and not tried to delete
some old data, but as the command (rm -rf) hung, I got suspicious:
