Serviceguard NFS Toolkit A.11.11.05 and A.11.23.04 Release Notes

Features and Fixes in Recent Releases

Fixes in The Versions A.11.11.04 and A.11.23.03

The ﬁxes in these versions are as follows:

DTS Number Problem Description

JAGaf11503 The /etc/rmtab ﬁle is not synchronized when an NFS package fails over to

the standby node. This is now documented as a known problem.

JAGaf23782 The ﬁle name of the NFS_FLM_SCRIPT script must be limited to 13

characters or fewer.

JAGaf26367 The nfs.mon script uses rpcinfo calls to check the status of various

processes. If the rpcbind process is not running, the rpcinfo calls time out

after 75 seconds. Because 10 rpcinfo calls are attempted before failover, it

takes approximately 12 minutes to detect the failure.

JAGaf37266 Change the MC/ServiceGuard NFS Toolkit product name to be

Serviceguard NFS Toolkit.

JAGae26082 In the nfs_xmnt script, if CNFS[0] is set to ” /xxx_dir” and CNFS[1] is set

to “/xxx”, the second ﬁlesystem is not mounted and you get the error

message: <date>Note... was already mounted.

New Changes in Serviceguard NFS A.11.11.03 and A.11.23.02

Serviceguard NFS Toolkit A.11.11.03 and A.11.23.02 include a new feature - File Lock

Migration. The detailed information of this feature is as follows:

• Each HA/NFS package designates a unique holding directory located in one of the

ﬁlesystems associated with the package. In other words, an empty directory is created in

one of the ﬁlesystems that moves between servers as part of the package. This holding

directory is a conﬁgurable parameter and must be dedicated to hold the Status Monitor

(SM) entries only.

• A new script, nfs.flm, periodically (default value is ﬁve seconds; you can change this

value by modifying the PROPAGATE_INTERVAL parameter in the nfs.ﬂm script) copies

SM entries from the /var/statmon/sm directory into the package holding directory.

• Upon package failover, the holding directory transitions from the primary node to the

adoptive node, because it resides in one of the ﬁlesystems conﬁgured as part of the

HA/NFS package.
