--qordeeddq3yuyl6f Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hey FreeBSD peeps, The zfs(8) manpage says that the maximum length of a dataset name is MAXNAMELEN (256 bytes). I've created a ZFS volume that has a dataset name length of 62. I don't see the ZFS volume in /dev/zvol and I noticed this sanitized error in dmesg: Aug 24 11:07:24 bh-build-01 kernel: [2395] ZFS WARNING: Unable to create ZV= OL tank/bhyve/productname/dev/users/username/username-shortened_productname= -dev-01/disk-01 (error=3D63). So I'm left wondering, does devfs have a smaller limit than ZFS for node paths?
