Hi, I'm running into a similar problem as described in https://lists.freebsd.org/pipermail/freebsd-stable/2014-August/079514.html Using zfsnap (sysutils/zfsnap) when trying to backup some zfs zvols like this: /usr/local/sbin/zfSnap -s -z -a 90d -r zroot/data/bhyve geom / zfs generates dmesg output like this: g_dev_taste: make_dev_p() failed (gp->name=zvol/zroot/data/bhyve/.... at 2016-11-19_09.05.00--90dp6, error=63) Is anybody aware of any work being done to loosen this 63 char limitation? Might somebody perhaps be able to share a more elegant workaround than "rethink your zfs names" ? Kind regards, Ruben
