[ovirt-users] Storage domain - defining fields

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!
