How to set nolock option with mount?

[Deepu Chakravarty]

I am running HPUX 11.11 rp2470 server. I need to mount one file system with 'nolock' option. How can I do that? Is it available in 11.11, if no what is the other workaround?

Thanks.

Shalom,

I don't think so, but here are two previous threads that will contain answers. Hopefully I didn't post to either one.

Hello,
I think that nolock option is only avalaible for nfs.
Just use mount command with nolock option like this:
mount -o nolock server:/my/exported/dir /pub

or add this line in your /etc/fstab
server:/usr/local/pub /pub nfs nolock

and mount -a

Yes , I need nfs mount.
But it is giving following error:
# mount -o nolock 80.0.0.172:/working /working
nfs mount: illegal file system specific option: nolock

usage: mount [-l][-v|-p]
mount [-F FStype][-eQ] -a
mount [-F FStype][-eQrV][-o specific_options]
{ special | directory }
mount [-F FStype][-eQrV][-o specific_options]
special directory

Hi Deepu,

If you're talking about an NFS file system and you want to stop any lock requests from going over the wire to the server, the correct mount option is "llock", which stands for "local lock".

This option is only available on HP-UX 11.11 (11i v1) and 11.23 (11i v2) and you need to install patches to get this feature. On 11.11 systems the patch is PHNE_34293 or later. On 11.23 systems the patch is PHNE_33099 or later.

Once those patches, or patches that supercede them are installed, you can use the "-o llock" option to enable local locking on a per-filesystem basis.

Let me know if you have any other questions about local locking with NFS.

Regards,

Dave

Very good suggestion. Patches told were applied and mounted file systems accordingly with 'llock' option. Now database is created and opened.
Thanks all.
