Serviceguard for Linux Version A.11.16 Release Notes
Patches and Fixes in this Version
Chapter 1 49
There was a deadlock in the code possible where one thread was
holding a lock while waiting for another lock that created a deadlock
condition with another thread.
• Resolution: The fix is to have the thread release the lock before
trying to acquire the other lock.
JAGaf45937: The value here will be used when reporting dates in
the log files of processes started directly or indirectly by cmcld.
cmviewcl -p does not show correct package status
• Problem: Under some conditions, cmviewcl -p pkg shows the state
and node as unknown. cmviewcl does show correct state. This has
only been reproduced under unusual conditions with cluster brought
up in single node mode.
• Resolution: The cmviewcl -p routine had been looking up package
state from the "view_node". This was corrected to check the real
package status.
The following defects have been fixed in HP Serviceguard for Linux
A.11.16.01:
JAGae91411: If subnet mask changes, online cmapplyconf does
not detect this
• Problem: If the subnet mask has been changed on a lan card used in
the cluster, a online cmapplyconf will not detect this change, so it
won’t update the cluster configuration. An offline cmapplyconf will
update the cluster configuration.
For example, if lan0 used a subnet mask of: 255.255.255.128 when
the cluster configuration was first applied, and now has been
changed to 255.255.255.192, when you run cmapplyconf you will
see:
# cmapplyconf -C cluster.ascii
Begin cluster verification...
