SSD cache bad superblock

Featured Replies

Getting some issues with a fresh unraid install/setup using unraid 6.12.4 and problems with the ssd cache, Ive tried different file systems on it, but regardless of what I choose Im unable to do anything with it. Weird part is that the overall Monitoring now shows everything as green and ok. Any advice moving forward? Dont want to start moving data on to this until Ive got it fixed.

Device is reporting busy, reboot and try formatting again.

Don't see any format attempt after the reboot, please confirm.

Afraid not :( Just to be clear, there is no data on the drive or the array atm which I need to keep.

You will need to try and wipe that device with a different OS, for some reason Unraid cannot do it.

Thats the weird thing, Windos insists that the device doesent contain anything. I'll see if I can run fdisk towards it and get it wiped that way.

According to Linux the device has two partitions:

 

Sep 22 09:41:17 Jupiter kernel: sdc: sdc1 sdc2

 

Post the output of 

fdisk -l /dev/sdc

Finally, after some tinkering with the drive ,it seems as if it was an ev0l Windows boot partition which was the culprate, I did away with it using dispart on the windoze comp. Removed it there and it came right up once I started the array.
