Extending an iSCSI disk on an Ubuntu VM causes the disk to go read-only?

[surfrock66]

I am wondering if I'm doing something wrong here. I have 2 Proxmox 8.2.2 hosts, and they are connected to a TrueNAS Scale which is presenting ZFS over iSCSI LUNS over fiber, everything works well. I have Ubuntu 22.04.04 VM's, with qemu-guest-agent installed, everything seems happy, until I need to extend a disk.

If I go through the Proxmox UI and edit the hardware, then extend the disk via "Disk Action -> Resize", the disk goes read only until I reboot. I feel like this wasn't always the case? Am I doing something wrong here? I can add this to my procedure, but I feel like this shouldn't require a reboot.

Example config below:

It may be helpful if you provided the logs that correspond to the operation.
I.e., open an ssh terminal, run "journalctl -f".
Perform resize.
Capture the logs that were written during the operation and provide them here (as text encoded with CODE, or SPOILER)

Good luck

Unfortunately, there are no logs. The host sees the disk extend as successful, and the VM stops recording all syslog at the time the extend initiates until after reboot.

What about dmesg in the guest?
