We have a X4100 running b66 exporting ZFS filesystems via NFS to
several HP-UX clients. Due to bug 6538387,
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6538387, we
must mount the ZFS filesystems from our X4100 server as NFSv2.
However, this causes problems with getconf(1) on this system:
hp-ux# mount -o vers=2 b66:/opt/tww /mnt
hp-ux# getconf NAME_MAX /mnt
getconf NAME_MAX /mnt: Operation not supported
hp-ux# mount -o vers=3 b66:/opt/tww /mnt
hp-ux# getconf NAME_MAX /mnt
255
We can "zfs set xattr=off" on the ZFS filesystems as, according to
zfs(1m):
xattr=on | off
Controls whether extended attributes are enabled for
this file system. The default value is "on".
However, this isn't enough. Is it possible to disable the extra
attribute bits used by NFS when NFSv3 is being used by the client? We
don't need any extra attribute bits more than the standard UNIX
permissions.
