Time Machine couldn't complete the backup. The backup disk is not in Max OS Extended (Journaled) format.

Hello,

I'm a fairly new and happy TrueNAS user, moving over from Unraid. I'm using my system to backup my Mac using Time Machine. This has worked very well until last night. There's been no software updates in the meantime, only a rare but not uncommon Mac system crash & reboot. I wonder what has happened and how to get my backups up and running again.

TrueNAS-12.0-U7-STABLE running on HPE Gen10 Microserver
macOS Catalina 10.15.7 running on iMac 27" late 2021
Both wired with brand new Cat6 UTP 1Gbps Ethernet to UniFi Dream Machine Pro

I've got plenty of these in /var/log/samba4/log.smdb (192.168.1.1 is my router). They also appear before the last successful backup was taken.

I don't have NFS or AFP running but rather suspect some issue on the Mac side. I can see the shares just fine.
