[ovirt-users] Storage domain - defining fields

[Gabi C]

Hello!

My setup 1 engine Fedora 19 ovirt 3.4 managing 3 nodes Fedora 19 + ovirt
3.4 updated; those nodes acts also as gluster server for 2 storage domains,
each domain 3 bricks replicated  ( so 3 bricks each).

I have one questions regarding the fields one have to complete when
defining a new storage domain and its importance.

First, field "*Use Host*" - you have to complete with one of the nodes. Of
course you can use any of the host in cluster, *but which is its
significance/importance*? * If you reboot that node, you suppose to have
any issue with the storage?*

The same question with field "*Path*" - gluster case - "*Path to gluster
volume to mount*" formatted as "HOST:VOLUME" , where host can be the same
as above mentioned field-  "*Use Host*" or any af the gluster cluster
member; *which is its significance/importance?*


*Again If you reboot that node, you suppose to have any issue with the
storage?*
My experience with rebooting these nodes*, *after moving VM's and putting
it in Maintenance was good*,* until yesterday, when after such reboot I've
got some corrupted VM images, and subsequently  I had to restore them.

Error message follows :

Exit message: cannot read header
'/rhev/data-center/mnt/glusterSD/10.125.1.194:gluster__data3/5fe658b1-43ff-4bfd-97d6-28217cf415df/images/321ad473-3741-4825-8ac0-6c416aa8f490/1a21454d-9931-4ed8-ba38-7126528664a1':
Input/output error."


Did I miss some step(s), beside moving VM's and puting node in maintenace,
before reboot one host node, servig also as gluster node?

Any hint, link would be appreciated!

Thanks!
