March 19Mar 19 First of all, I am new to this so please be gentle and speak to me like a newborn.I am setting up my first NAS and have decided to create the following based on the drives I have available:Array: 1 x 26tb HDDCache: 1 x 2tb SSD ZFSPool 1: 2 x 8tb SSD RaidZ1Pool 2: 3 x 4tb SSD RaidZ1My issue is that one of the 4tb SSD drives refuses to accept ZFS and will only mount in XFS. When adding the one 4tb to the array it has no issue, but trying to make it part of the ZFS pool it refuses to mount the pool. I also have gone through the format process at the bottom of the main page.I have done a little research and installed Unassigned Devices and UD+, making sure they are in destructive mode. I have also installed the ZFS Master plugin, and run the drive through PreClear, all to no avail. The drive is the same brand as the other two of the same size.I must be missing something, and would love any help you all could offer.

Like I said, I'm new to this and still figuring it out 😂I'll happily and gratefully take recommendations as to a better setup for my drives.
March 20Mar 20 exfat support is new and might be somewhat limited compared to xfs, btrfs, zfs. XFS is the usual format for array disks.

March 20Mar 20 sdb (disk1) has multiple partitions. Click on it to get to its page, then erase partitions then set it to xfs and format it in Array Operation.

Thanks again.
March 20Mar 20 For the pool issue, reboot and try again, if it still fails to format, post new diags.
March 22Mar 22 Author Reboot didn't work, but another user suggested trying the wipefs and sgdisk commands which did the trick. Thanks for the support and guidance.
