Hi,
I'm having the following problem with an invariant of SL56, the cern
flavour. I thought perhaps that someone may have come across this
with SL56
Here in Sydney, we installed slc56 x86_64 on a Dell Power Edge R510 with
48Gb of RAM.
The problem we have is that once the os is installed slc56 top, free and
vmstat only reports 32Gb. All the yum updates were performed.
To check we booted with the rescue mode, SLC 5.6 and all the commands
report 48Gb .
A further check we installed RHEL 5.6 x86_64 it reports 48Gb .
Is there some tweak to the kernel that needs to be done? Or any cause to
the problem. Any ideas are much appreciated.
Cheers,
Aldo
Is this machine being a virtulization host?
I know that on SL5 for xen hosts (I haven't verified it for KVM hosts)
you only see the amount of memory that the host has left, not the total
amount of memory.
The best way I found to look at the full memory in this situation was to
do a "xm list" which lists all the xen client's memory, as well as the
hosts.
