2.2.19 and file lock on NFS?

2.2.19 and file lock on NFS?

[apark]

Hi,

Recently upgraded to 2.2.19, along with new nfs-utils(0.3.1).
But I have a program that requires a exclusive write lock
on a NFSed directory.  When I was using 2.2.17 all was ok,
but now it returns ENOLCK.  Does anybody else have the
same problem?
Thanks

-Andrew

Hi,

You are probably failing to run the statd daemon or you may have set
up over-restrictive /etc/hosts.(allow|deny).

See the latest NFS-HOWTO for a full description on how to set up
locking.

Cheers,

Or /var/lib/nfs/statd does not exist on your system, or it is not
writable by the uid rpc.statd runs under (rpcuser on Red Hat boxes
with all the upgrades).

I've had this problem myself, I don't think it's covered in the FAQ.

I haven't checked if the rpcuser thing is a redhat-ism, probably is,
their script is not doing anything special with rpc.statd so they
must have hacked it into the executable.
