Thx a lot, i already got rid of the multipaths.
Now 5 tries later i try to understand who disk space calc works.
I already understand that the combined GByte limit for my drive sdb is around

Now the thin pool creation kicks me! :)

I think you should input the size as 500GB if your actual disk size is 530 ?

Hi,
i try to set up a 3 node gluster based ovirt cluster, following this guide:
https://www.ovirt.org/blog/2017/04/up-and-running-with-ovirt-4-1-and-g
luster-storage/
oVirt nodes were installed with all disks available in the system,
installer limited to use only /dev/sda (both sda and sdb are HPE
logical volumes on a p410 raid controller)
Glusterfs deployment fails in the last step before engine setup:

Hi Oliver,
I see that multipath is enabled on your system and for the device sdb it creates
mpath and once this is created system will identify sdb as
"3600508b1001c350a2c1748b0a0ff3860". To make this work perform the steps below.
1) multipath -l (to list all multipath devices)
2) black list devices in /etc/multipath.conf by adding the lines below, if you
do not see this file run the command 'vdsm-tool configure --force' which will
create the file for you.
blacklist {
devnode "*"
}
3) mutipath -F which flushes all the mpath devices.
4) Restart mutipathd by running the command 'systemctl restart multipathd'
This should solve the issue.
Thanks
kasturi.
