June 4, 201016 yr I woke up this morning to one of the disks in my array showing a red light. Disks fail, no big deal. I tried stopping the array immediately so I could power down until I could get a replacement, but all of the drives stuck at "Unmounting." I thought it might have just been taking a long time, so I let it continue and went off to work. It's been well over 5 hours and the array's still not stopped. The disks still show as "Unmounting," but presumably there's no progress. I'm assuming that I can power the server off manually and replace the disk, but I thought I should ask here first. What should my course of action be here?
June 4, 201016 yr A disk cannot un-mount if it is busy. A disk is busy if it is the current directory for a process you may have started, or if you have a file on it open for reading or writing. you can tell the process Id of what is keeping the disk busy by typing: /usr/bin/fuser -mv /mnt/disk* /mnt/user/*
