All drives shown as detached

Support
1

After a reboot all drives are shown as detached.
In the concole I can list the files of the atteched disks.

For one testdisk the name fits but not the size and serial.

I’m not using raid. Rockstor version: 4.6.1-0

If I try to delete a pool, I get the info, that all data will be lost.

The web UI didn’t finds new disks.

How could I refind the drives?

Thanks.

@Kelte, welcome to the Rockstor community.

That first detached disk shows 0 bytes, compared to all of the other detached disks, was that disk removed at some earlier time (before the reboot) but not removed from the pool it belonged to?

Re:

So for each of the pools you still have a mount point under /mnt2/ to get to the files?

And if you can get to the disks’ contents it also means that you don’t seem to have any connectivity issues (disk cables/connectors, etc.), so that’s good, but would likely have been the easier fix :frowning:
