Hi,
I can confirm that after setting these two options, I haven't encountered
disk corruptions anymore.
The downside, is that at least for me it had a pretty big impact on
performance.
The iops really went down - performing inside vm fio tests.

Hi Krutika, Leo,
Sounds promising. I will test this too, and report back tomorrow (or
maybe sooner, if corruption occurs again).

Hi,
I have an all in one ovirt 4.2.2 with gluster storage and a couple of windows
2012 VMs.
One w2012 is showing actual size 209GiB and Virtual Size 150 GiB on a thin
provision disk. The vm shows 30,9 GB of used space.
This VM is slower than the others mainly when we reboot the machine it
I also have a problem with the history database growing in size so need to
reduce this, it has nearly doubled in less than a week.
select pg_size_pretty(pg_database_size('ovirt_engine_history'));
pg_size_pretty
32 GB
(1 row)
pg_size_pretty
56 GB
(1 row)
Hello everyone, when I want to use the thin client to connect the virtual
machine, I will use spice mode to connect, but I need to specify the port of
the host and spice password. Could you please tell me where I can check the
spice password of the virtual machine
By default ovirt uses 'sharding' which splits the files into logical chunks.
This greatly reduces healing time, as VM's disk is not always completely
overwritten and only the shards that are different will be healed.
Maybe you should change the default shard size.
Best Regards,
Strahil

Hi Strahil,
Ok. Looks like sharding should make the resyncs faster.
I searched for more info on it, but couldn't find much.
I believe it will still have to compare each shard to determine whether
there are any changes that need to be replicated.
Am I right?

It's ok, migrating to 4.3.2 on the oVirt node (from 4.3.0) did the job of
fixing it.
It is a bug if you intend on using the ovirtmgmt network to deploy your ansible
from, and you need it to have an IP address already on that range! But - it
works as expected with the ovirtmgmt bridge setup so
It could also be this:

Hi,
we see some VMs that show an inconsistent view of snapshots. Checking die
database for one example vm shows the following result:
engine=# select snapshot_id, status, description from snapshots where vm_id =
'40c0f334-dac5-42ad-8040-e2d2193c73c0';
snapshot_id |
Having an issue with starting one of my VM's. Looks like there was a
problem with an auto generated snapshot on the VM. The snapshot file is
missing:

Each shard is a separate file of size equal to value of
"features.shard-block-size".
So when a brick/node was down, only those shards belonging to the VM that
were modified will be sync'd later when the brick's back up.
Does that answer your question?

Hi there,
I am running ovirt engine 4.2.8.
I did cpu hotplug for windows 10 guest os, ovirt (from 1*2*1 to 2*2*1)
successfully, and the output of virsh vcpuinfo also shows now there are total 4
vcpus:
# virsh --readonly vcpuinfo 13
VCPU: 0
CPU:51
State: running
" ovirt (from 1*2*1 to 2*2*1) "
I mean change cpu count from 2(1*2*1) to 4(2*2*1)

You may be in an ideal situation introducing "customary" CentOS and afterward
