April 15, 20242 yr Hi there, I recently set up and have been experimenting with a ZFS cache pool with 3 ssd drives in a raid 0 configuration. I had an unclean shutdown today and now with the array online it's showing that the ZFS cache pool is unmountable: unsupported or no file system. It's prompting me to format the drives and create a new file system but I'd like to avoid that if at all possible. I would appreciate any help with this matter. I can upload a diagnostic report if required. Thanks in advance.
