April 24, 20242 yr Hello everyone I'm currently in the process of transferring my Unraid to new hardware. Unfortunately my system crashed, with the result that the cash drive is no longer recognized. The system was there too. to transfer the cash to a pool i.e. second M2 SSD. I have already tried the following. 1. Second SSD removed from the poll and restarted the array 2. Cashe completely removed from the pool Array started, stopped and added again. 3. tries to access via unassigned devices Does anyone know how I can save the data? Thanks for help tower-diagnostics-20240424-1045.zip

April 24, 20242 yr Author ok, I put the second SSD back in the pool and it seems to work Label: none uuid: be357807-42ce-4500-b64e-62a462ba2323 Total devices 2 FS bytes used 429.95GiB devid 1 size 1.82TiB used 444.05GiB path /dev/nvme0n1p1 devid 2 size 1.82TiB used 104.03GiB path /dev/nvme1n1p1
April 24, 20242 yr Author one more question. The way I have it set up now, it should serve as a failsafe with the second SSD, right?
April 24, 20242 yr Community Expert If it's configured as a redundant pool yes, you can post new diags to confirm.
April 24, 20242 yr Author I just noticed that the first cache is working and the second one is not doing anything and is always 0B/s at read/writes is that normal? Edit: After an array restart, the second cache drive now also works tower-diagnostics-20240424-1045.zip Edited April 24, 20242 yr by swiss01
April 24, 20242 yr Community Expert Those appear to be the same diags as before, would need current ones, with the pool mounted.
April 24, 20242 yr Community Expert The pool is using the single profile, i.e., not redundant, and it will only mount if both devices are available, you can convert to raid1 to make it redundant.
April 26, 20242 yr Author After trying to change the pool for a long time, it finally worked. I don't know why, but somehow unraid didn't want to take over the settings and I couldn't format the cache account either. After several attempts and restarts it finally worked. many thanks for your support tower-diagnostics-20240426-1257.zip
