April 29, 20179 yr I know I can unmount a drive from the console sync umount /dev/sd? - where ? is the disk you want to unmount I can stop the array from the webgui to do maintenance. If I want to unmount a single drive, is there a way to do that from the webgui? Is there an app?
April 29, 20179 yr Author I ran umount /dev/md8 (in this case disk 8). Replied "not mounted", but it still showed up in the GUI as mounted...
April 29, 20179 yr Then its not mounted. But you're getting into a very weird edge case, because the GUI is expecting that it handles everything. And if you want to unmount a single drive so that you can run the file system checks on it, while leaving the rest of the array up and running, then you're very much on your own. Good luck with that... Edited April 29, 20179 yr by Squid
May 1, 20179 yr Author What I was looking for is a way to test a single drive (i.e. XFS_REPAIR) on a single drive without taking the array down. So the net, then, is you can't unmount a single drive with Unraid. You have to stop the array first, then all the drives are unmounted (which is what I did and XFS_REPAIR ran fine found a couple things and corrected). I had errantly assumed that unraid would keep the system going just as if a drive had failed (i.e. build the data from parity). Glad my foolish 'edge' case didn't cause any problems!
