Disk resize failed and reset the VM

[Tux-Stuttgart]

Hello,

I have resized the hard disk by 50 gb but got the following error:

TASK ERROR: VM 176 qmp command 'block_resize' failed - client closed connection

This is not the biggest problem, but that the VM was reset afterwards. Unfortunately, a mysql database also broke during the reset.

Before the first reset, there were still a few small changes to the VM pending. I then tested it again, but with the same error.
I didn't want to risk another test, because the VM is in productive use with us. I have therefore enabled the hard disk expansion via an additional disk and lvm. This worked without any problems. We use an nfs storage with a qcow image for the VM.
I also tested the resize on another VM on the same node but without any problems.

Any ideas how to get rid of this problem?

Best regards from stuttgart

Hello,

during today's scheduled maintenance, the VM needs to be rebooted. I used this downtime to stop and restart the VM. After that, resizing worked again. I thought a ha-manager triggered start after the crash would have the same result, but it looks like something else happened during the restart and fixed the problem. Do you have any idea why this is happening and how to fix it properly?

Regards
