August 22, 20241 yr I'm not sure if this is an issue with mover or an issue with my cache pool itself but I'm unable to to remove an nvme drive I have in my cache pool, it's the one remaining issue I have with my Unraid server. So here's the rub, I have set ALL my shares to run off of the array, in preparation of removing my entire SSD cache pool and redoing it with JUST sata SSD disks (so I can use the 2 nvmes in my gaming rig). So what I have now is a pool made up of 3 sata ssds and 2 nvme drives. I have read through all the guides that I can see on removing pool drives and they all say 2 things (can't be done in a raid 0 pool), and that all u have to do is remove the drive restart the array (so long as it's set to the correct raid level) and it will rebuild the cache pool WITHOUT the drive you removed. However I DON'T get that result and instead I get the too many Disks missing error. Been racking my brains for days and can't figure it out but it's probably something stupid. My cache pool is a btrfs file system and it has been converted from a raid 0 to a raid 1 via the rebalance area in the cace drive menu. I would just remove all the disks but there is like 500gb stored on my cache pool and if really rather not loose ANY of it. Thanks in advance and I can post screenshots if needed , I will edit this post and add my diagnostics files when I get back to my PC. Thanks in advance you guys and girls.
August 23, 20241 yr Community Expert Solution Stop array, unassign all pool devices, start array, stop array, re-assign all pools devices, start array, that should correct the pool cfg, and you should now be able to remove one device at a time.
August 23, 20241 yr Community Expert Also, if you want mover to transfer files from the 'cache' pool to the array, then the 'cache' pool needs to be set as the primary storage and the array as the secondary storage in the settings for a share. Mover will not move any files that are on a pool if you only have the array set as primary storage.
