Thanks - I've tried converting it to single mode via the GUI but nothing seems to happen. I have noticed the following warnings appearing: pool BTRFS too many profiles (You can ignore this warning when a pool balance operation is in progress) Is there another method to change back to single mode?

Hey all, Recently got a new 1tb SSD for my cache. Thought I could add it to my existing cache pool with a 2tb drive. Since then, my intial cache drive has started displaying as full at 1.31tb. The drive appears to be loading in read-only mode - mover doesn't move files, and scrub aborts after 0 seconds. btrfs filesystem usage displays the following: Overall: Device size: 2.75TiB Device allocated: 2.56TiB Device unallocated: 199.12GiB Device missing: 0.00B Device slack: 0.00B Used: 2.37TiB Free (estimated): 244.14GiB (min: 217.15GiB) Free (statfs, df): 128.00KiB Data ratio: 1.57 Metadata ratio: 2.00 Global reserve: 512.00MiB (used: 16.00KiB) Multiple profiles: yes (data, metadata, system) Data Data Metadata Metadata System System Id Path single RAID1 RAID1 DUP RAID1 DUP Unallocated Total Slack -- -------------- --------- --------- -------- --------- --------- -------- ----------- --------- ----- 1 /dev/nvme0n1p1 708.01GiB 951.84GiB 2.00GiB 2.00GiB 32.00MiB 16.00MiB 199.12GiB 1.82TiB - 2 /dev/nvme1n1p1 - 951.84GiB 2.00GiB - 32.00MiB - 1.02MiB 953.87GiB - -- -------------- --------- --------- -------- --------- --------- -------- ----------- --------- ----- Total 708.01GiB 951.84GiB 2.00GiB 1.00GiB 32.00MiB 8.00MiB 199.12GiB 2.75TiB 0.00B Used 522.99GiB 951.84GiB 1.61GiB 271.78MiB 208.00KiB 32.00KiB I've been attempting to copy data off the cache to the array (in case I have to wipe the thing), and am noticing btrfs errors: Sep 24 16:48:35 NORTHDAMEN kernel: BTRFS error (device nvme0n1p1 state EA): level verify failed on logical 59627181359104 mirror 1 wanted 0 found 1 Sep 24 16:48:35 NORTHDAMEN kernel: BTRFS error (device nvme0n1p1 state EA): level verify failed on logical 59627181359104 mirror 2 wanted 0 found 1 I've ran a file system check and receieved no errors. Pool device stats also show no errors. I'm a little unsure what to do next - I have appdata backups so I can always wipe and restore, but I'm hoping that is a last resort (backup is about three weeks out). Wondering if there's a way to revert the cache pool to just use the 2tb drive? Will take any advice. Thanks,
