Length of ZFS volume names

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 ZVOL tank/bhyve/productname/dev/users/username/username-shortened_productname-dev-01/disk-01 (error=63).

So I'm left wondering, does devfs have a smaller limit than ZFS for
node paths?

Thanks,
