Hi Pen, It seems that you email has stalled for a couple of days on qq.com. I believed that I've replied to the query you've sent from another mailbox, under the subject line [ovirt-devel] How did vm.merge do when we delete a snapshot that pointed by several other's snapshot's srcVol (as several other snapshot's backing) bottom line: you cannot create a topology like [4] in vdsm storage. _______________________________________________ Devel mailing list [email protected] http://lists.ovirt.org/mailman/listinfo/devel
