hi bernard, wow, 200MB for a bunch of domUs ;) but seriously, maybe it's a dm-multipath setting problem, i had kind of the same (instead of having the guests filesystem images as files on a gfs volume i just have on lun per guest); during a failover some of the guests would become instable or even lose control over their disks. my problem was that i forgot to set: no_path_retry queue in the settings for my storage. since i did that the domUs survive multipath failovers nicely. regards, johannes > Hi, > > Sorry for the confusion here.
