[PVE-User] Replica stuck after a network outgage...

[Marco Gaiarin]

Situation: two servers with a direct link with a 10Gbit/s speed; after
creating a new VMs on one side, and filled up with data, i've enabled
replica.
Network link goes down, i'm investigating, but now work.

Sending side i catch:

and receiving side i see two processes stuck:

 root at svpve1:~# ps aux | grep [z]fs
 root     23000  0.0  0.1 301468 81720 ?        Ss   12:10   0:01 /usr/bin/perl /usr/sbin/pvesm import rpool-data:vm-123-disk-0 zfs tcp://10.5.251.0/24 -with-snapshots 1 -allow-rename 0
 root     23003  0.0  0.0   8956  3404 ?        S    12:10   0:11 zfs recv -F -- rpool-data/vm-123-disk-0

time of processes match with the crash time.


Can i safely kill them? Thanks.
