Snapmirror volumes are 'guarantee disabled' by design prior to 7.3. In 7.3, that is changed to 'guarantee enabled'.

Hello Toasters,

I upgraded a FAS6040 from 7.2.4 to 7.3. It has several snapmirror destination volumes and now I am getting these errors in the messages file whenever snapmirror runs:

Sun Nov 16 00:15:25 EST [wafl.vol.guarantee.fail:error]: Space for volume lib_content0 is NOT guaranteed

vol options lib_content0 shows this:

nosnap=off, nosnapdir=off, minra=off, no_atime_update=off, nvfail=off, ignore_inconsistent=off, snapmirrored=on, upgraded_replica, create_ucode=off, convert_ucode=off, maxdirsize=62914, schedsnapname=ordinal, fs_size_fixed=on, compression=off, guarantee=volume(disabled), svo_enable=off, svo_checksum=off, svo_allow_rman=off, svo_reject_errors=off, no_i2p=off, fractional_reserve=0, extent=off, try_first=volume_grow, snapshot_clone_dependency=off

The above only happens to snapmirror destination volumes. We also have non-snapmirrored volumes in the same aggregate and they do not show this behavior, so it seems to be related to snapmirror.

There is plenty of room in the containing aggregate:

df -Ah aggr1

aggr1 10TB 7422GB 3006GB 71% aggr1/.snapshot 0GB 0GB 0GB ---%

The total size of the volumes in aggr1 is nowhere near filling it.

The filer with the snapmirror source volumes is running 7.2.3.
