TapIt Posted November 4, 2022 Share Posted November 4, 2022 One of the drives in my cache pool suddenly died, thankful it was a raid 1 and I was able to recover the data to a folder on my array following these instructions. Now that I have the data on the array in a temp folder how can I get the cache recovered or get the data into the right spots in the array? Should I just be copying the data to the array backed shared location for each area? Such as /cache/sharefolder/files -> /array/temp/files -> /array/sharefolder/files? or once I replace the broken drive should I just take the files from the temp directory and put them back on the cache. leaf-diagnostics-20221103-1905.zip Quote Link to comment
JorgeB Posted November 4, 2022 Share Posted November 4, 2022 Basically you just need to fix the pool and restore the data to their original folders/shares. Quote Link to comment
TapIt Posted November 4, 2022 Author Share Posted November 4, 2022 Thanks for the quick response. Just to confirm the next steps, I should just physically replace the dead NVME drive with a new one. Assign that new one to the slot of the dead one and start the array back up. BTRFS will then repair the raid 1 and the cache should be good to go? Quote Link to comment
JorgeB Posted November 4, 2022 Share Posted November 4, 2022 Are you sure the NVMe is dead? It might just have dropped, if you want us to take a look post the diagnostics. Quote Link to comment
TapIt Posted November 4, 2022 Author Share Posted November 4, 2022 I’m pretty sure it is dead. I attached the diagnostics to the original post. thanks again. Quote Link to comment
JorgeB Posted November 4, 2022 Share Posted November 4, 2022 Missed those, but they are before array start, after would be better, SMART does look weird for that device, it's incomplete. Quote Link to comment
TapIt Posted November 4, 2022 Author Share Posted November 4, 2022 Attached the diagnostics with the array started. leaf-diagnostics-20221104-1222.zip Quote Link to comment
JorgeB Posted November 4, 2022 Share Posted November 4, 2022 Other NVMe device is not decrypting, possibly because the LUKS headers are missing, since the pool is backed up you can try re-formatting, then if there are more issues with that device replace it, or if you have a spare replace it now then test the other one.
