Hi,

I have hit a unique problem. Using oVirt 4.0.2.7-1.el7.centos since last one month and I have hit a unique problem. The Engine is reporting that Disk space allocated to Hosted engine is full and is not allowing to login to engine's console to clear some files as well. When I try to add additional storage to Hosted engine, engine admin portal reports that as Engine VM is not managed by oVirt Engine, it cannot extend the storage.

Now the questions are:

1. Is it that enabling advanced DWH on the engine host is the root cause for 100GB of disk getting filled in about 1 month?

2. How do we clear the disk of some unwanted files and extend the space?

3. How do we reset the DWH database to basic?

Note: CentOS 7.2 is not even allowing us to login to console to do any action. Booting the Hosted Engine VM with Live CD etc., looks like is ruled out in this case.

Hi,

In another instance where the engine is on a different host, we have observed that out of 100 GB nearly 70% is consumed in just about 20 odd days.

Is it that DWH database and the logs really take so much of space so fast? How do we reduce the disk utilization? This will be a major issue when compared to other hypervisors management platform.

How do we address this and arrest this super fast disc consumption?

Thanks & Regards,

Hi,

I have hit a unique problem. Using oVirt 4.0.2.7-1.el7.centos since last one month and I have hit a unique problem. The Engine is reporting that Disk space allocated to Hosted engine is full and is not allowing to login to engine's console to clear some files as well. When I try to add additional storage to Hosted engine, engine admin portal reports that as Engine VM is not managed by oVirt Engine, it cannot extend the storage.

Now the questions are:

1. Is it that enabling advanced DWH on the engine host is the root cause for 100GB of disk getting filled in about 1 month?

2. How do we clear the disk of some unwanted files and extend the space?

3. How do we reset the DWH database to basic?

Note: CentOS 7.2 is not even allowing us to login to console to do any action. Booting the Hosted Engine VM with Live CD etc., looks like is ruled out in this case.

Hello Didi,

Apart form oVirt-engine, nothing else is running on the server. Engine is running on CentOS 7.2 minimal installation. We have 2 hosts, 1 iSCSI storage, about 19 VMs and 5 Networks. In this setup oVirt engine is running in a separate VM created on VMWare ESXi. In 20 odd days, it consumed around 70GB out of 100 GB!!!

In another setup, we have only one host, hosted engine, 9 VMs, 2 Networks, 1 FC Storage. In about 30 odd days, 100% of available 100 GB consumed!! It is in this setup CentOS is not allowing us to loginto engine VM as no space to create any temp files on the storage. We have ISO Domain created on this engine VM. But that's only about 3 GB in size.

Both setup are not exposed to internet. Hence, any malware is ruled out.

We have observed, the logs are also growing and we have not found that logs are not rotating. All logs right from day one are kept intact. Nothing in the user files. Because no user is allowed to use this VM.

What else it could be? 100% consumption without even a warning, is very strange.

Thanks & Regards,

Anantha Raghava

Hi,

Is it that DWH database and the logs really take so much of space so fast?

Are you sure that DWH database is the only thing using much space? Did you
check disk space usage?

DWH db size depends on the size of your setup - number of
hosts/VMs/disks/NICs/etc.

You can also affect this by configuring granularity and history
length, check e.g.:

https://www.mail-arc=
hive.com/search?l=3Dusers(a)ovirt.org&q=3Dsubject:%22Re\%3A+\[ovirt=

http://lists.ovirt.org/pipermail/users/2=

How do we reduce the disk utilization? This will be =
a major issue when
compared to other hypervisors management platform.

How do we address this and arrest this super fast disc consumption?

Hi,

I have hit a unique problem. Using oVirt 4.0.2.7-1.el7.centos since last one
month and I have hit a unique problem. The Engine is reporting that Disk
space allocated to Hosted engine is full and is not allowing to login to
engine's console to clear some files as well. When I try to add additional
storage to Hosted engine, engine admin portal reports that as Engine VM is
not managed by oVirt Engine, it cannot extend the storage.

Now the questions are:

1. Is it that enabling advanced DWH on the engine host is the root cause for
100GB of disk getting filled in about 1 month?

2. How do we clear the disk of some unwanted files and extend the space?

3. How do we reset the DWH database to basic?


Note: CentOS 7.2 is not even allowing us to login to console to do any
action. Booting the Hosted Engine VM with Live CD etc., looks like is ruled
out in this case.
