HP Serviceguard Version A.11.17 Release Notes, March 2006 (revised)
Serviceguard Version A.11.17 Release Notes
Fixed in This Version
Chapter 1 43
JAGaf40323 (SR8606380087): /etc/cmcluster/
cmknowncmds undocumented and prone to be
deleted
What was the problem? A new internal file called cmknowncmds now
exists in /etc/cmcluster. The file was originally shipped as an empty
file giving the customer no idea the importance of the file. If this file is
accidentally deleted the cluster can fail to start and messages are logged
in syslog that say:
Error opening /etc/cmcluster/cmknowncmds
What was the resolution? A comment was added to this file to instruct the
customer not to remove the file.
JAGaf39230 (SR8606378981): cmlvmd exits on
accept(2) returning ENOBUF
What was the problem? A TOC occurs and an error like the following
shows up in syslog:
Sep 2 14:32:28 u962004w cmlvmd: Failed to accept
connections from commands: No buffer space available
What was the resolution? Since no buffer space available is a transient
error, LVM daemon can safely ignore this after logging the error in
syslog.
JAGaf38580 (SR8606378322): ioctls should be more
resilient against ENOMEM
What was the problem? A package will fail to start or halt due to the
add/delete IP ioctls encountering the transient ENOMEM (Not enough
space) error without SG retrying the add/delete IP ioctls. The package
control logs will show something like:
Failed to add IP 192.1.1.1 to subnet xyz: Not enough space
What was the resolution? The add/delete IP ioctls will be retried upon
encountering the transient ENOMEM error thus increasing the
resiliency towards this error and not causing the package start/halt to
fail.
