November 11, 20223 yr Hi , Hopefully you guys can help me out for this issue. I add 1 more nvme ssd to cache pool as redundancy and the process is success. However after 1 day, the new nvme ssd got issue and not detected. I remove back the ssd from the cache pool because it detect no device & the system run as normal with single nvme ssd cache pool. Today 1 re-seat the nvme back and got detect by the system back (as unasigned device), but the original cache pool nvme ssd show "Unmountable: No pool uuid". I found this thread in the forum but not sure is this the same solution to run command below? btrfs-select-super -s 1 /dev/sdX1 I afraid if i run the command will loose all my data. Got my several important vm inside. 🤕 Need you guys help on this. I attach also the diagnostic file. aiesb-svr-01-diagnostics-20221111-1502.zip Thanks guys.
November 11, 20223 yr Community Expert Solution Without rebooting since the last diags but with the array stopped type: wipefs -a /dev/nvme1n1p1 Then start array and post new diags.
November 11, 20223 yr Author Hi JorgeB, Thanks for quick reply. You are saving my day. Now the cache pool is up again. I attach new diags just in case. aiesb-svr-01-diagnostics-20221111-1851.zip Is it safe to add back "Dev 3" to the pool as redundancy?

November 11, 20223 yr Author Hi JorgeB, Now i added back "Dev 3" in the cache pool and balancing is running. Hopefully my new nvme ssd no repeated issue again. Thanks you very much for your help 👍 Edited November 11, 20223 yr by Muhamad Aidil Karim
