tjb_altf4 Posted December 23, 2021 Share Posted December 23, 2021 Adding some drives which required some moving of cables, one hba cable wasn't hooked back up correctly and so those drives didn't appear. Array was not started, pools were not mounted. No problem shutdown and fix, they reappear on boot, all good Now I see a warning against the drives in those pools "All existing data on this device will be OVERWRITTEN when array is Started" Is this actually going to overwrite the data on those drives ?

(the two 4 device pools are the ones in question) Quote Link to comment
Solution tjb_altf4 Posted December 23, 2021 Author Solution Share Posted December 23, 2021 (edited) OK after finding a similar report by another user, I decided to reboot as he did and the warning went away as it did for him... Started the array and all is well... thank fk. This is the second time Unraid's BTRFS pool state management has tripped me up, it would be great to see the BTRFS implementation in Unraid get a bit more love before we dive in the deep end with ZFS.
