Hello. I am running bhyve with 11 Current. SVN version is r291495 and I have problem about zfs recv -F basicly. I backup the vm machine by zfs send -R /zones/vm/win7pro@20160117 | lz4 - win7pro_20161117.lz4 and then transfer win7pro_20161117.lz4 to other machine, and then using lz4cat win7pro_20161117.lz4 | zfs recv -F zones/vm/win7pro to have a copy. I do this several times with other vms, it runs fine. today when I run zfs recv, the dmesg has a WARNING message: ZFS WARNING: Unable to create ZVOL zones/vm/win7pro/disk0@afterinstall (error=17). (I also have a snapshot of afterinstall) and zfs list -t snapshot is zones/vm/win7pro@afterinstall 11.5K - 21.5K - zones/vm/win7pro@20160117 12K - 22.5K - zones/vm/win7pro/disk0@afterinstall 2.70G - 5.83G - zones/vm/win7pro/disk0@20160117 10.0G - 13.1G - when I boot the VM. it crash at somepoint. any idea what is going on? I try zfs recv in the same host, same result(also has the WARNING message.) and I try dd the disk0 to file, and then restore from file. the vm runs fine. Thanks.
