HI admins,

I want to change the value of maxuprc in kernel .
and its immedaite-changes should get affect without reboot.BUt when i chenged using kctune
i got belw output

kctune maxuprc=nproc*9/10+1
NOTE: The configuration being loaded contains the following change(s)
that cannot be applied immediately and which will be held for
the next boot:
-- The module 'libusb' depends on a module 'mass_storage' which is
not available without a kernel rebuild.
WARNING: The automatic 'backup' configuration currently contains the
configuration that was in use before the last reboot of this
system.
==> Do you wish to update it to contain the current configuration
before making the requested change? yes
* The automatic 'backup' configuration has been updated.
* The requested changes have been saved, and will take effect at
next boot.
Tunable Value Expression Changes
maxuprc (now) 3780 nproc*9/10 Immed
(next boot) 3781 nproc*9/10+1

=====================
it showing next reboot

server is B.11.23 U ia64 3619037392

Hi,

>>>The module 'libusb' depends on a module 'mass_storage' which is
not available without a kernel rebuild.<<<

This shows answer to you. When it depends on other module which needs a kernel rebuild, then you need to live with it.

[Duncan Edmonstone]

Sounds like someone made some change already that aren't yet implemented following a reboot.

What do you see from running:

kconfig -D

I think by SAM we can change without rebuild as SAM will check all the things since maxuprc is dynamic
Biut m getting following error thro sam.

Enter Value/Expression OR q(quit) = nproc*9/10+1

The Expression is not valid

Please help on this..

and tell me any switches used with sam,so reboot is not required.

[Duncan Edmonstone]

now I'm confused... are you doing this through sam (kcweb) or via kctune?

Hi Ducan,

I reverted back the value,since its asked for next boot.

kconfig -D

I want to do it in SAM.As i posted,sam shows error.

In kctune i can change the value,bit it asks next boot.

I heard that sam will check all the things and it rebulid the kernel since maxpurc is dynamic.

himacs

[Duncan Edmonstone]

Thats indicating a lot of kernel module changes pending - someone or something at some point has requested these changes - you can probably figure out what running "kclog -a" and looking at all entries since the last reboot.

It *is* possible to ditch all these changes (using "kconfig -H"), but I wouldn't advise that you do that as the changes may have been made for a very good reason (e.g. have you done a major patch installation and then interrupted the install near the end?), in which case you may need to schedule a reboot so you can get them all applied.

HI admins,

Is there any switch can be used with kctune so that reboot is not required as maxuprc is dynamic.


please help me on this

himacs

[himacs]

Hi ducan,

Thanks for ur reply..

Since maxuprc is dynamic ,it should be changed without boot.
