Disk failure; array won't stop

[dgallaher]

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?

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/*

That's got it, thanks.  Your help is always appreciated.
