3.1.2 MxFS-Linux Release Notes

Matrix File Serving Solution Pack for Linux 6

9081 File locks cannot be acquired when MxFS-Linux is not

running

When MxFS-Linux is installed, the NSM (network status

monitor) support is provided by /opt/polyserve/sbin/vstatd,

which replaces the traditional /usr/sbin/rpc.statd. vstatd is

cluster-aware and requires membership in an active cluster to

run. File locks can not be acquired over NFS while NSM support

is unavailable; lock requests will be rejected with ENOLCK.

9789 Client times out before it can mount exported filesystems

If the clientʹs mount command times out consistently (for

example, for every retry of a backgrounded mount), one

possible cause is that the client IP address cannot be resolved to

names at the server. The server mountd may take longer

attempting to translate the client address than the client mount

is prepared to wait.

To resolve this problem, ensure that the server can translate the

clientʹs IP addresses to names. This can be done in any of several

ways: by adding entries to the serverʹs /etc/hosts file, by

deploying a DNS in-addr.arpa zone that covers the client

addresses, or by avoiding the use of nonroutable private

addresses (for example, do not use network 192.168/16 without

private DNS in-addr support).
