February 16, 20224 yr Hey ya'll I have a 3 drive cache pool in raid1. All 3 drives are 1TB, I have 1.5TB of usable space. One of my drives (sdg) has given me errors, so I replaced the drive with an identical new ssd (sdd). sdg is still connected as an unassigned drive. When I do a btrfs balance, my logs are still showing entries saying Feb 16 02:24:21 Mk4Alpha kernel: BTRFS info (device sdg1): found 14 extents Feb 16 02:24:22 Mk4Alpha kernel: BTRFS info (device sdg1): relocating block group 10354819727360 flags data|raid1 I'm not sure why? I don't have access right now to the server to disconnect the failing drive. Is that the only way to truly remove the drive? If I bring the array down, is Wireguard still active? That's my only way into the server right now. I tried doing btrfs device delete missing /mnt/cache but this says `ERROR: error removing device 'missing': no missing devices found to remove` And the following is my output for the pool from btrfs root@Mk4Alpha:~# btrfs filesystem show Label: none uuid: 7ed018b8-03ec-408f-b72f-64210d53b1ed Total devices 3 FS bytes used 540.46GiB devid 2 size 931.51GiB used 370.00GiB path /dev/sdf1 devid 3 size 931.51GiB used 368.03GiB path /dev/sdd1 devid 4 size 931.51GiB used 368.03GiB path /dev/sdc1 Thanks! mk4alpha-diagnostics-20220216-0230.zip Edited February 16, 20224 yr by Blaze9
February 16, 20224 yr Community Expert Device sdg was successfully removed from the pool, any mentions of it should stop once you reboot, possibly after an array re-start.
