Hello together, today i had an issue with my cache drive on my Unraid Server. I used a 500GB SSD as a cache drive.
Unfortunately i added another cache drive (wanted a separate drive for my VMs and accidentally added into the cache device pool) After starting the array and all the setup for the cache device pool was done i stopped the array again. I removed the second drive from my cache device pool again. I started the array again - formatted the removed drive, mounted it with unassigned devices.# And then I realized the following error in my Unraid Cache Devices. "Unmountable: No File System" Unfortunately I cannot mount it again. Can you please help me? Thank you in advance Best Regards Patrick Attached are the information requested. root@JARVIS:/dev# uname -a Linux JARVIS 4.19.107-Unraid #1 SMP Thu Mar 5 13:55:57 PST 2020 x86_64 Intel(R) Core(TM) i5-9600K CPU @ 3.70GHz GenuineIntel GNU/Linux root@JARVIS:/dev# btrfs --version btrfs-progs v5.4.1 root@JARVIS:/dev# btrfs fi show Label: none uuid: a07d7790-4cb2-4dd6-b62c-c877c291ff7f Total devices 1 FS bytes used 384.00KiB devid 1 size 465.76GiB used 1.02GiB path /dev/nvme0n1p1 warning, device 2 is missing bad tree block 1139295649792, bytenr mismatch, want=1139295649792, have=0 ERROR: cannot read chunk root Label: none uuid: 1df2cdfd-d2cb-498b-be96-13cb969e11f5 Total devices 2 FS bytes used 77.57GiB devid 1 size 465.76GiB used 61.00GiB path /dev/sdb1 *** Some devices missing
