Hi,

I have proxmox 4.1 (initial install was 4.0) on a pair of SSD's in mirror using ZFS.

I want to do a snapshot of rpool and than send/receive the snapshot for the purpose of backup.

For reasons unknown (and I am by far no expert), I can create the snapshot (at least its listed) but send/receive will send only a small file. However, the actual rpool is almost 50GB big and it should send that much the first time it does a send/receive. At least that was the behavior that I observed when sending the VMs snapshots over the wire.

See here:
Code:
root@VMNode01:/# zfs list -t snapshot
NAME  USED  AVAIL  REFER  MOUNTPOINT
rpool@13Dec2015  0  -  96K  -
root@VMNode01:/# zfs send -R rpool@13Dec2015 | mbuffer -s 128k -m 2G | ssh root@somedomain.com 'mbuffer -s 128k -m 2G | zfs recv -Fduv MainVol/BACKUP'

root@somedomain.com's password:

root@VMNode01:/#

Anybody an idea?
