I have my UNRAID (7.2.7) NAS on a UPS and have a DAS connected to it. When I power down the DAS, Unraid won't auto-mount or let me mount the drives unless I reboot Unraid. Is there some setting/script that I can use to have UNRAID ignore the lost connection and just remount the drives when the power turns on again? Yeah, I can connect the DAS to the UPS and not shut it down, but I need to move it around from time to time to other devices when I'm moving large amounts of data since transfers are faster on a direct connection.

No setting as far as I am aware. Unraid is not hot-plug aware so cannot handle drives dropping offline that are part of the main array or a pool. Only Unassigned Devices can be handled like that.

I should have been more specific and mentioned that these are unassigned drives that it's happening to.

Maybe unassigned devices plugin would help

I have it installed. But help in what way?

Are you unmounting the Unassigned Devices before powering them down?

Yes. This is what they should when reattached.

Why do they have multiple partitions?

These were external drives that I schucked and put into a DAS. I'd love to reformat them but current HD prices have kept me from getting another drive to move the data to and perform a format.

I found a manual fix that would allow me to re-mount them without rebooting Unraid. Sharing in case anyone runs into this issue down the road. We should have the option to be able to hot swap drives not part of an array or pool without having to unmount or reboot Unraid.

Open terminal

mount | grep disks

Find the unmounted drives, copy their path and names

umount -l /mnt/disks/<drive name>

Now you can mount as normal in unassigned devices.
