Hello Everyone, i just purchased a new Sandisk 1TB SSD and would like to use it as a cache drive. My current unraid setup consists of all ZFS file system. I keep encountering a msg that my SSD is unmountable even though it passed the preclear process and a SMART tests. Looking through the logs, i encounter the following. May 2 21:05:16 UNRAID root: mount: /mnt/cache: wrong fs type, bad option, bad superblock on /dev/sdh1, missing codepage or helper program, or other error. May 2 21:05:16 UNRAID root: dmesg(1) may have more information after failed mount system call. May 2 21:05:16 UNRAID kernel: XFS (sdh1): Invalid superblock magic number May 2 21:05:16 UNRAID emhttpd: shcmd (747): exit status: 32 May 2 21:05:16 UNRAID emhttpd: /sbin/btrfs filesystem show /dev/sdh1 2>&1 May 2 21:05:16 UNRAID emhttpd: ERROR: no btrfs on /dev/sdh1 May 2 21:05:16 UNRAID emhttpd: /mnt/cache: no btrfs May 2 21:05:16 UNRAID emhttpd: shcmd (748): modprobe zfs May 2 21:05:16 UNRAID kernel: spl: loading out-of-tree module taints kernel.

May 2 21:05:17 UNRAID emhttpd: shcmd (749): exit status: 32 May 2 21:05:17 UNRAID emhttpd: /mnt/cache mount error: Unsupported or no file system Is there a way to change the the SSD drive solely to BTRFS even though all my other drives are ZFS so it can be use as a cache drive?
