    [SOLVED] Windows Guests crashing during backup

    Thank you Moayad, These machines have 64GB. ZFS grabs up to 32GB and the VMs are allocated a total of 40GB (no ballooning) so it looks like ZFS is not releasing RAM fast enough during a backup. I'll get some more RAM anyway.

    I have been struggling with the "delicacy" of ZFS. Specifically large write loads bringing the system to a halt (addressed in another thread) and the difficulty in zfs-sync and zfs-replication to handle broken pipes. In regards to the latter I found this...
