[lxc-users] Big snapshots abort...

[Michel Dubé]

No luck,

I installed rsync package from 16.04 (rsync_3.1.1-3ubuntu1_amd64.deb) and
gave it a try but no luck. Same problem. Snapshot +25G big aborts.

But it succeeded manually by the next command:

rsync -a -HAX --devices --delete --checksum --numeric-ids -q
/var/lib/lxd/containers/emergence/ /var/lib/lxd/snapshots/
emergence/emergence-03-12-2016
