Mount/Unmount Performance on Systems with
Large Memory Sizes
Problem
On systems with 16 GB or more of physical memory, mounting
and unmounting of file-systems can take a long time. A single
mount or unmount may take up to 30 seconds on a 16 GB system.
This time increases significantly with increase in memory size.
What You See
You see long delays during mount, unmount, system startup, and
system shutdown. For example, a 16 GB system with 100
file-systems can take up to 3000 seconds, or 50 minutes, to mount
or to unmount all of them. This means that system startup and
shutdown can each take at least 50 minutes.
What to Do
One or more patches for this problem will be available shortly.
Please contact HP Support for the availability of these patches.
