March 10, 20179 yr I noticed that my virtual machine and appdata, in addition to some other files, are stored on the cache disk, which is obviously not protected. What would be an easy and logical way to move those files to a data disk, in order to provide redundancy protection? Thanks. Lev

It's not recommended to put VMs and dockers on the array as performance is degraded because of the constant writes to the array. Edited March 10, 20179 yr by dboonthego

If the cache disk fails, do you need to start from scratch to restore the files on it? Can you mirror the two cache disks outside of the array? Thank you, Lev

Can you mirror the two cache disks outside of the array? More than on cache disk is considered a "cache pool" which is typically setup as RAID 1 giving you a mirror of each other. If one disk fails, you simply replace it and it will rebuild; and yes, this is all outside the array. I think a single cache disk can be formatted as XFS or BTRFS, but a pool requires BTRFS. If your existing cache disk is not BTRFS, you'll be required to format it.
March 10, 20179 yr Community Expert Lots of info about managing cache pools in the V6 FAQ sticky at the top of this subforum. Also, there is a plugin (part of the Community Applications plugins) to backup appdata, not sure if it does VMs or not.
