[PVE-User] vzdump ping loss on snapshot

[Muhammad Yousuf Khan]

when i vzdump one of my production VM i lost ping however the option i
select for backup is snapshot. for example, it is like when i use the
option suspend for backing up VM instead of snapshot. and the VM image
resides on LVM partition.


here is the command

vzdump 707  --remove 1 --mode snapshot --compress lzo --dumpdir /data/vmbk/

this is the command which i run and i take local backup then i
transfer it to Remote server via SSH via Script.

here is my partition detail. moreover i am using RAID 1 and over the
RAID i am using LVM.
