Sorry for the long delay.

This worked. Thank you very much.

Hi, /dev/sda3 should work, the error here is possibly due to filesystem
signature.

Can you please set wipefs=yes? For example

[pv]
action=create
wipefs=yes
devices=/dev/sda3

Can you provide gdeploy logs? I think, it's at ~/.gdeploy/gdeploy.log

Re: [ovirt-users] Hosted Engine Setup with the gluster bricks on the same disk as the OS

[Mike DePaulo]

Well, I tried both of the following:
1. Having only a boot partition and a PV for the OS that does not take
up the entire disk, and then specifying "sda" in Hosted Engine Setup.
2. Having not only a boot partition and a PV for the OS, but also an
empty (and not formatted) /dev/sda3 PV that I created with fdisk.
Then, specfying "sda3" in Hosted Engine Setup.

Both attempts resulted in errors like this:
failed: [centerpoint.ad.depaulo.org] (item=/dev/sda3) => {"failed":
true, "failed_when_result": true, "item": "/dev/sda3", "msg": "
Device /dev/sda3 not found (or ignored by filtering).\n", "rc": 5}

It seems like having gluster bricks on the same disk as the OS doesn't
work at all.

I am going to buy separate OS SSDs.

Thank you very much. Is my process for doing this (listed in my

I am using oVirt Node 4.1.1.1. I am aware of the manual partitioning
requirements. I am guessing I have to create an LV for the OS that
does not take up the entire disk during install, manually create a pv
like /dev/sda3 afterwards, and then run Hosted Engine Setup and
specify /sda3 rather than sdb?

Hi Mike,

If you create gluster bricks on the same disk as OS it works but we 
do not recommend setting up gluster bricks on the same disk as the os. 
When user tries to create a gluster volume using by specifying the 
bricks from root partition it displays an error message "Bricks in root 
parition not recommended and use force at the end to create volume".


Thanks

[ovirt-users] Hosted Engine Setup with the gluster bricks on the same disk as the OS

[Mike DePaulo]

Hi. I am trying to follow this guide. Is it possible to use part of my
OS disk /dev/sda for the bricks?
https://www.ovirt.org/blog/2017/04/up-and-running-with-ovirt-4-1-and-gluster-storage/

I am using oVirt Node 4.1.1.1. I am aware of the manual partitioning
requirements. I am guessing I have to create an LV for the OS that
does not take up the entire disk during install, manually create a pv
like /dev/sda3 afterwards, and then run Hosted Engine Setup and
specify /sda3 rather than sdb?

Thanks,
-Mike
