Hey Checkyourlogs Fans,

Today I had an interesting case where a customer called in to let us know that Checkpoints were stuck on their Windows Server 2019 Hyper-V Host. Everything had been working great on this host since it was upgraded from Windows Server 2016 back in November. The only change was we upgraded to Veeam 9.5 Update Rollup 4, and then we started experiencing these issues with Checkpoints and Disk Locks.

How we noticed this was the failing Veeam Backup and Replica Jobs to and from this host. You can see that it is stuck with Creating Checkpoint at 9%. We hadn’t patched this host since it had been deployed and figured that might be the issue.

The first thing I normally try in this situation is not to have to reboot the Hyper-V Host as that is pretty invasive. So I tried stopping the Hyper-V VMMS Service. That just hung in a stopping state. At this point, we decided just to Patch and reboot the host and reboot.

This did solve our problem as seen in the screen shot below. So now I have a note to self of patching my Hyper-V Hosts before moving to Veeam 9.5 UR4. Although I’m not 100 percent certain if it is related I’m pretty sure because that was the only change in our environment.

Thanks,


Dave
