[ovirt-users] after rebooting nodes cannot activate them

[Gabi C]

Hello!


1 engine- not hosted FC 19 + ovirt 3.5 ;
3 nodes - F20 and ovirt 3.5 patternfly due to high vdsm memory usage. All
theree nodes serves as glusterfs server - 3 replicated bricks.
After putting DC in maintenance -  all VM shutdown, storages in maintenance
(ISO, Data, Export) , stop gluster volume and finally hosts in maintenance
, runned "yum update" on all nodes, reboot them, "Confirm host has been
rebooted" but trying to activate them raise "Gluster command [<UNKNOWN>]
failed on server....." and hosts goes in non operational.


vdsm log goes like:

*NB*
*Reinstalling all host after moving in Maintenance from Non-op avtivates
them and I am able to start gluster volume, activate stoarage domains and
so on.......*
