Yagami Posted January 9, 2022 Share Posted January 9, 2022 Hi Everyone, Rebooted the server to make some changes, and now the nvme cache is showing me the below error (error log below also). Couple of notes : - I run all dockers in this Cache and set to prefer cache - I chose the "directory" mode in intial set-up for docker and not Vdisc) The drives are still detected, and showing on the list of usable drives, but unraid is asking me to format The error : The Log : Jan 9 06:15:51 Multiverse kernel: nvme0n1: p1 Jan 9 06:15:51 Multiverse kernel: BTRFS: device fsid 765f6f1d-a3a7-487b-a5db-2c284bf3918d devid 1 transid 21878 /dev/nvme0n1p1 scanned by udevd (1687) Jan 9 06:16:16 Multiverse emhttpd: Sabrent_Rocket_Q4_7D37071518CD00000204 (nvme0n1) 512 3907029168 Jan 9 06:16:16 Multiverse emhttpd: import 31 cache device: (nvme0n1) Sabrent_Rocket_Q4_7D37071518CD00000204 Jan 9 06:16:16 Multiverse emhttpd: read SMART /dev/nvme0n1 Jan 9 06:16:23 Multiverse kernel: BTRFS info (device nvme0n1p1): turning on async discard Jan 9 06:16:23 Multiverse kernel: BTRFS info (device nvme0n1p1): using free space tree Jan 9 06:16:23 Multiverse kernel: BTRFS info (device nvme0n1p1): has skinny extents Jan 9 06:16:23 Multiverse kernel: BTRFS info (device nvme0n1p1): enabling ssd optimizations Jan 9 06:16:23 Multiverse kernel: BTRFS info (device nvme0n1p1): start tree-log replay Jan 9 06:16:23 Multiverse root: mount: /mnt/nvme: wrong fs type, bad option, bad superblock on /dev/nvme0n1p1, missing codepage or helper program, or other error.

Yagami Posted January 9, 2022 Author Share Posted January 9, 2022 (After further reading here and there) I'm able to navigate the content of the "unmountable Cache pool" using Linux commands (cd / ls..) folders and files seem to be there, but for some reason the cache is showing as unmountable. Let me know guys if you faced same issue before. Thanks Quote Link to comment
