filecache_min max error

[zxcv · Accepted solution]

Hi Duncan / Dennis ,

I have resolved the problem.

As you can see that hpvm was ocupying all the memory , i just changed the values startup disable and automatic memory allocation to "0" in /etc/rc.config.d/hpvmconf file .

Thanks for your help.

Which version of 11.31 are you running and which version of HPVM?  My guess is you're running the March 2012 or later Fusion and HPVM v6.1 or later.

Dennis,

I was reading this from the OP's kmeminfo output:

>> Physical memory = 522455 31.9g 100%

Is that wrong?

Hi Duncan,

The kmeminfo output displays the physical memory in three formats - number of pages, bytes, percent.  Looking at his output:

Physical memory usage summary (in page/byte/percent):

Physical memory = 522455 31.9g 100%

There are 522455 memory pages, 32GB of RAM in the system.  That being the case, we know that the system is using 64K memory pages (32 * 1024 * 1024) = 33,554,432 bytes / 522,455 pages = 64.  This makes sense on an Integrity VM host because we automatically tune the base_pagesize=64 on systems configured as VM Hosts or VSPs.  

My guess is this system is running March 2012 release or newer and Integrity VM v6.1 or newer because at that release we automatically grab 92% of the available memory when HPVM starts and assign it to the HPVM/vPar memory pool.  This is expected behavior that is documented in the Integrity VM/vPars v6.1 Admin Guide.

Hope this helps,

Dave

hmmm - it would appear I have lost the ability to read! Not sure how I was reading that as 52GB???

Yes but it also says:

(in page/byte/percent):

nbpg: 65536 bytes

And 32 GB matches the pseudo-swap total.

I did it like this:

kctune filecache_min=5%

kctune filecache_max=10%

Thanks Dave , i always had a doubt as to how the calculation was done.
