Hi,

If you have set up VM disks as Thin Provisioned, the VM has to pause when the disk image needs to expand. You won't see this on VMs with preallocated storage.

It's not the SAN that's running out of space, it's the VM image needing to be expanded incrementally each time.

Cheers

Alex

Hi Fred,

This is an iSCSI storage. I'm attaching the VDSM logs from the host where this machine has been running. Should you need any further info, don't hesitate to ask.

Thanks.

Regards.

Hi,

What kind of storage do you have ? (ISCSI,FC,NFS...)
Can you provide the vdsm logs from the host where this VM runs ?

Thanks,

Freddy

Hi,

We're running oVirt 3.6.4.1-1. Lately we're seeing a bunch of

The storage domain is far from being full, though (400+ G available
right now). Could this be related to this other issue [1]? If not,
how could I debug what's going on?

Thanks.
