Kernel problems

[Joel Pavon]

Hi!

I have problems whit a virtual partition in server RP8400, I was change the kernel parameters but after of the shutdown I check the changes using SAM and there are any changes! so, I review the file /stand/system and it's diferent the file and the kernel to show the SAM

by example: on SAM the value of maxswapchunk is 6145 but on the file /stand/system the value is 16348. this is an example I have more kernel parametes like this.

Any body know a solution??

regards!

Hi Joel:

It would be useful to state the OS release. Other specific differences you believe you see would be helpful, too. 'maxswapchunks' is a deprecated parameter in current releases. You can/should view kernel settings with 'kmtune' (pre 11.23) or 'kctune' (11.23 or later).

Regards!

sorry, The OS Version is 11.11

I change the valir of this parameters on SAM:
maxswapchunks=16384
maxuprc=3687
msgmap=4098
msgmni=4096
msgseg=32767
msgtql=4096
ncsize=34816
nfile=63488
nflocks=4096
ninode=34816
semmap=4098
semmni=4096
semmns=8192
semmnu=4092
shmseg=120
vps_ceiling=64;

this is the value after the reboot the server (on SAM)
maxswapchunks=6145
maxuprc=1536
msgmap=258
msgmni=256
msgseg=7168
msgtql=256
ncsize=25620
nfile=34780
nflocks=800
ninode=20500
semmap=514
semmni=512
semmns=2500
semmnu=492
shmseg=24
vps_ceiling=16

This is the file /stand/system (only about kernel parameters):
STRMSGSZ 65535

What were the values BEFORE you made the changes? Did the values change at all?

If not, I suspect that the new kernel never got processed. After making the changes in SAM did you go up to the ACTIONS menu and select "PROCESS NEW KERNEL"? This will recompile your kernel and ask if you want to reboot your system. If you didn't do this, then that is your problem. If you did, then something else strange is going on.

[Joel Pavon]

yes, I process the new kernel after changes, and reebot the kernel after build the kernel parameters.
