4 a.m.
Hi,
I'm running the ovirt engine 3.4 series. I've created a snapshot of a VM
with an OS and data disk before upgrading the machine.
The upgrade went fine and I now want to remove the snapshot.
Unfortunately this fails with the error:
"Cannot remove Snapshot. Low disk space on target Storage Domain
stadius-virt2_PERC."
So I can't free disk space by removing the snapshot because I don't have
enough space?
When I look at the VM the disks are shown as preallocated (which is what
I selected during installation). When I look at the storage tab and list
the disks in my storage domain, the disks are now shown as thin
provisioned with the actual size > virtual size.
How can I remove this snapshot? I don't have enough free disk space in
my storage domain to duplicate the data disk of my VM.
Regards,
Rik

Snapshot removal (merge) includes a create volume phase. This volume is temporary and gets
removed once the snapshot merge is completed. Its size is the size of the disk.
That means that in order to remove the snapshot, the storage domain should have available
size that is equal to the disk size.

Snapshot removal (merge) includes a create volume phase. This volume is temporary and gets
removed once the snapshot merge is completed. Its size is the size of the disk.
That means that in order to remove the snapshot, the storage domain should have available
size that is equal to the disk size.

Subject: [ovirt-users] Can't remove snapshot due to low disk space on storage domain?
Hi,
I'm running the ovirt engine 3.4 series. I've created a snapshot of a VM
with an OS and data disk before upgrading the machine.
The upgrade went fine and I now want to remove the snapshot.
Unfortunately this fails with the error:
"Cannot remove Snapshot. Low disk space on target Storage Domain
stadius-virt2_PERC."
So I can't free disk space by removing the snapshot because I don't have
enough space?
When I look at the VM the disks are shown as preallocated (which is what
I selected during installation). When I look at the storage tab and list
the disks in my storage domain, the disks are now shown as thin
provisioned with the actual size > virtual size.
How can I remove this snapshot? I don't have enough free disk space in
my storage domain to duplicate the data disk of my VM.
Regards,
Rik

New subject: Can't remove snapshot due to low disk space on storage domain?
Hi,
Thats unfortunate :-(. It would have been great if oVirt told me during
the creation of the snapshot that I would be unable to remove it later
due to unsufficient free space in the storage domain :-).
The VM has two disks - a small and a large one - so the snapshot
contains both. Can I still remove the large disk while it has snapshots?
Luckily the used disk space in the (preallocated) large disk is low
enough so I can fit it on another temporary disk then.
Does the free space have to be in the same storage domain, or can oVirt
use another storage domain for the temporary volume? IOW, can I add an
NFS storage domain which oVirt can use to create the temporary disk on?
Regards,
Rik

Snapshot removal (merge) includes a create volume phase. This volume is
temporary and gets removed once the snapshot merge is completed. Its
size is the size of the disk.
That means that in order to remove the snapshot, the storage domain
should have available size that is equal to the disk size.

Hi,
I'm running the ovirt engine 3.4 series. I've created a snapshot of a VM
with an OS and data disk before upgrading the machine.
The upgrade went fine and I now want to remove the snapshot.
Unfortunately this fails with the error:
"Cannot remove Snapshot. Low disk space on target Storage Domain
stadius-virt2_PERC."
So I can't free disk space by removing the snapshot because I don't have
enough space?
When I look at the VM the disks are shown as preallocated (which is what
I selected during installation). When I look at the storage tab and list
the disks in my storage domain, the disks are now shown as thin
provisioned with the actual size > virtual size.
How can I remove this snapshot? I don't have enough free disk space in
my storage domain to duplicate the data disk of my VM.
Regards,
Rik

I'm not sure I understand which RHEV version you're using now.
If you're using RHEV 3.5, it is possible to remove a snapshot of a single disk.
You can do it via webadmin, Under the 'Disks Snapshots' subtab of the relevant
storage domain, in the 'Storage' main tab.
As for your second question, the free space has to be in the same storage domain.

New subject: Can't remove snapshot due to low disk space on storage domain?
Hi,
I created the snapshot on the Snapshots subtab of the Virtual machines
tab. I did this when my engine (and host) was running oVirt 3.4. It
is/was a snapshot of the entire VM (I deselected the memory state).
I since upgraded the engine to 3.5.
When I look at the snapshots subtab of the virtual machine, I see the
Current snapshot which is "Active VM" and the snapshot I created before.
This snapshot is a snapshot of both the OS and data disk.
I can not delete the second snapshot when the VM is running. If I power
down the VM, I can't remove the snapshot as it brings up the error I
mentioned before.
However, when I look at the disk snapshots subtab of the storage tab
(like you suggested), I see both disks with a snapshot and I can select
"Remove" there while the VM is running. Is it safe to remove them this
way? This will only remove the snapshot and not the disk (and data) from
my (running) VM?
Regards,
Rik

If you're using RHEV 3.5, it is possible to remove a snapshot of a
single disk.
You can do it via webadmin, Under the 'Disks Snapshots' subtab of the
relevant storage domain, in the 'Storage' main tab.
As for your second question, the free space has to be in the same
storage domain.

Hi,
Thats unfortunate :-(. It would have been great if oVirt told me during

due to unsufficient free space in the storage domain :-).
The VM has two disks - a small and a large one - so the snapshot

Luckily the used disk space in the (preallocated) large disk is low
enough so I can fit it on another temporary disk then.
Does the free space have to be in the same storage domain, or can oVirt

Indeed, removing the disk snapshot from the 'Disk Snapshots' subtab will remove
only the snapshot of the disk, not the disk itself.
Regarding snapshot removal while the VM is running - this feature is pretty new (live
snapshot merge). AFAIK, this feature is tech preview for 3.5. It also depends on the OS
you're using on the hosts. RHEL 7.1 supports it, but again, as tech preview.
Therefore, the safest way to remove the snapshot of the disk would be to do it while the
VM is not running.

New subject: Can't remove snapshot due to low disk space on storage domain?
Hi,
OK since my hosts are still CentOS 6.6, I will schedule downtime.
Will removing it this way also require the additional disk space in the
storage domain?

Regarding snapshot removal while the VM is running - this feature is
pretty new (live snapshot merge). AFAIK, this feature is tech preview
for 3.5. It also depends on the OS you're using on the hosts. RHEL 7.1
supports it, but again, as tech preview.
Therefore, the safest way to remove the snapshot of the disk would be to
do it while the VM is not running.

Hi,
I created the snapshot on the Snapshots subtab of the Virtual machines
tab. I did this when my engine (and host) was running oVirt 3.4. It
is/was a snapshot of the entire VM (I deselected the memory state).
I since upgraded the engine to 3.5.
When I look at the snapshots subtab of the virtual machine, I see the
Current snapshot which is "Active VM" and the snapshot I created before.
This snapshot is a snapshot of both the OS and data disk.
I can not delete the second snapshot when the VM is running. If I power
down the VM, I can't remove the snapshot as it brings up the error I
mentioned before.
However, when I look at the disk snapshots subtab of the storage tab
(like you suggested), I see both disks with a snapshot and I can select
"Remove" there while the VM is running. Is it safe to remove them this
way? This will only remove the snapshot and not the disk (and data) from
my (running) VM?
Regards,
Rik

It will require an available size according to the disk snapshot you're attempting to
remove.

It will require an available size according to the disk snapshot
you're attempting to remove.
Be warned: the downtime will be as long as it will take your storage to
copy the full size of the disk for each snaphot. Our server with a few
snaps on 1TB disk took more than a day of downtime!
