Post-fix edit: BTRFS cache drive corrupted. Read-only mounted, copied data to another disk, formatted, copied data back, shares etc work again.
Just did an upgrade on my main system/array, was running 100% fine on 6.4.0 6.4.1 from memory, stopped array and ran upgrade to 6.6.1 from "Update OS" in tools, rebooted server and booted into 6.6.1 successfully, however there are now no user shares (shows "There are no exportable user shares"). The share folders and all data/files seems to still be available on the disks, all dockers and VMs still listed though most will not start. After looking at threads from others having same/similar problem, can confirm netstats plugin is not installed.
Running XFS for array and BTRFS for single 500GB cache drive, 3x Ironwolf 10TB (1x parity), 1x Ironwolf 8TB, 1x Ironwolf 10TB unused (to preclear later and add to array). I did do a full unRAID flash drive image backup prior to upgrade so have that going for me.. but would rather just get 6.6.1 working if I can.
Any help would be greatly appreciated.
