[ovirt-users] Re: VM has been paused due to no Storage space error.

Thursday, 5 December 2024

Hi, 

We setup a new iSCSI storage with 16TB, plenty of space. 
Install a new VM (Ubuntu 24) with only one disk, 50GB, thin-provisioning 
After some minutes it pauses. 
Move the disk to another storage and we were able to start the VM. Don´t no for how long.

Running on CentOS 8, Version 4.5.4-1.el8 

Did the same test in another environment: 
CentOS 9, Version 4.5.6-1.el9, whitout any problem

Hi, 

The information is really unclear. 
In previous emails you state you use preallocated disks, now you tell us it only happens
on thin provisioned disks. 
Also the VM disk was 300GB, and now its 80GB. 

How did you check the LV size? Can you show me the command + output. 
What does: vdsm-tool dump-volume-chains storage-id give for the disk that has the issue?
The VM has 1 or more disks? 
Can you also do a virsh --readonly dumpxml <vm> on the hypervisor where the vm runs
and give the output? 

Thanks 
Jean-Louis

Hi, 

Can't find any error on vdsm log. What should I look for? 
The size of the Logical Volume for that disk is 80GB 
We have plenty free space. 
The VM cannot start again. it only happens with thin provision disks. If I move the disk
of the paused VM to another storage it works for a day and than it pauses again. 

Thanks 
José

Hi, 

I think you need to dig deeper into the issue. 
- What does vdsm logs show for example? 
- What is the size of the Logical Volume for that disk? 
- The Volume Group (checked on that hypervisor) still gives free space? 
- There is no way to start the VM again without getting it paused?

But we are in Version 4.5.4-1.el8, so still don't know.

I don't think this article will help you. It specifically talks about upgrading to RHV
4.4SP1 (which is oVirt 4.5). There is a config workaround but it says don't do this in
RHV 4.4SP1.

Ok, discard is not enabled on the disk. 
Reading [ https://gitlab.com/qemu-project/qemu/-/issues/1621 |

I'm sure the image did not grow over 110% of its virtual size 

Any idea?

Hi, 

Not talking about discard on the storage domain, but on disk/vm level. 
Is it enabled there?

Hi Jean-Louis, 

The VM disk is 300GB with 216GB available, preallocated on a iSCSI storage with 3532GB
total and 1932GB free. 
Have enable incremental backup. Discard After Delete is not enabled.

Hi Jose, 

How big are the disks? And what size are they on the storage? 
I guess the images are qcow2? 

Is discard enabled?

Hello, 

running ovirt Version 4.5.4-1.el8 on Centos 8, randomly we have this error: 
VM has been paused due to no Storage space error. 
We have plenty of space on the iSCSI storage. This is a preallocated disk, VirtIO-SCSi. 
No user interaction. It happens, so far, with 3 VM, Windows and Ubuntu. 
This service was stopped: dnf-makecache.service 

This is what I found on the engine log:
