June 27, 20251 yr I misread the line "Preserve current assignments” in New Config, so all Pools ware wiped. I´m strugling to get them back correctly, What is the correct/best practice for doing it. As always, happy for help.
June 27, 20251 yr Community Expert Solution On main, create a new pool with the same name and number of slotsassign the pool device(s), if there are subpools, don't create them, just assign all the devices together, order is not important, leave the filesystem set to autostart the array to import the pool
June 27, 20251 yr Author Thanks, it worked. I did like this yesterday, nut could not get the share assignment correct.
December 3, 2025Dec 3 Author Can I restart this thread?I wanted to remove the cache drive from a Zpool. Following this guide, did not work. I was not aloud to start the Array after unassigning the cache drive. Then I ran New config, made a pool with the same name as before, and added the drives leaving file system set to auto (without slots for the subpool drives). After starting the Array, the pool drives were not imported. Only option to reformat the drives. I´m in trouble on this. Any way to fix this? I hope….

Leave the filesystem set to auto, the pool will then be sorted during import.

The GUI doesn't currently support removing devices from subpools; you can do it using the CLI. More info here:https://forums.unraid.net/topic/46802-faq-for-unraid-v6/page/4/#findComment-1512308
