Hi, I created a striped zfs pool on two nodes and then put replicated glusterfs on top. This is just testing cluster so no spare drive or raidz. I tried to pull out one drive, the pool got into unavailable state and all vms on top of glusterfs froze. I discovered that I need to set failmode to...

Hi, as I can not login to gui for few days on either server (no HA) I would like to try migrate containers to second node and reboot first one. I was searching on this forum but I am unable to find proper command. I have just found that I should use pvectl insted of vzmigrate but I have not...
