Hi,
i face a very wierd problem and although i found a few threads with "similar" problem, i wasn't able to diagnose and fix.
this is stopping the replication from finishing and also makes the guest unusable.
the guest system hangs almost immediately when issuing fsfreeze-status
the load averages on the guest system jumps, here is an excerpt of the top command while the guest was still responding:
you can see that there's 10% usage on waiting state but with iotop i can't see anything
After that the only thing i can do is reset the guest.
if i disable qemu-guest-agent from the VM options the issue dissapears but qemu-guest-agent is nessesary for our setup
the guest is running cloudlinux with kernel 4.18.0-147.8.1.el8.lve.1.x86_64
any clues on how can i diagnose the issue?
