System won't boot after kernel parameter change

[Kuekuatsheu]

I changed the kernel parameter maxfiles and maxfiles_lim to 409600. When I try to reboot the server, it won't boot anymore. Do you have any idea on how to recover my vpar?

Thanks.

hi

yiu can try boooting the alternate kernel that is /stand/vmunix.old

from the MON prompt try the following


MON>vparload -p -b


the alternate kernel name may be /stand/vmunix.old


If you had another Boot Disk in the VPAR which you might have detached during this kernel change, you can put in that disk which has the old kernel and try from the MON prompt

MON>vparload -p -B

Tried it. System still won't boot. Even when I use vmunix.prev

Any other ideas?

Thanks.

[sujit kumar singh]

What is the Error that you are getting trying to boot from the alternate Kernel and what is the error that is for booting the Old kernel?

can you please post the errors in both the cases please?

Error is the same as booting from the old and new kernels. Shown below:

[MON]
vPar "ANALYTICS" failed to load the kernel due to:

non-bootable boot media; incorrect vPars software installed;

or incorrect boot media EFI path in vPars database.
Try using "vparload -p ANALYTICS -E 0" to load the vPar.
Error loading "ANALYTICS". Shutting down "ANALYTICS"...
[MON] ANALYTICS has halted.

We already tried vparload -p ANALYTICS -E 0, still doesn't work.

[Don Morris_1]

First, halt the vPar (should halt itself eventually, you might have to do a vparreset from another vPar, though).

Then try one of the following:

1) vparload -p -b /stand/backup/vmunix

[vmunix.prev is more of an 11.11-ism. For v2 and later, you specify the backup/alternate kernel configuration -- the default auto backup is "backup" so this is likely to be there for your pre-tunable changes].

2) vparload -p -o \"maxfiles=2048 maxfiles_lim=4096\"

That may only work on a v3 kernel -- I don't remember for sure when boot-string tunable settings was done

3) Add more interleave to the vPar until it boots. What the problem is here is that you've increased this tunable -- and kernel data structures which use it and are allocated relatively early in boot grew accordingly. The problem is that early boot memory is a very scarce resource (there's a bootstrapping going on -- a little known good memory is used to get things built to bring in some more memory... then that memory is used to discover the rest of the system and bring the rest of the memory in, after which things work pretty normally from the allocator's point of view. Unpinned PDK memory is that second bit [Pinned is the original known good if you're wondering]). What you've indirectly asked the system to build is just too much for the memory known/available at this intermediate stage (which is usually just Interleave [or on a system with only CLM, the CLM which is addressed from low ranges].)

Personally, I'd go option (1) and then re-tune the system.

[Kuekuatsheu]

Tried options 1 and 2 to no avail. How do I add more interleaves? Maybe that will work. Thanks.

[Don Morris_1]

What happened with (1)? Was there no backup configuration on your machine [you could try last_install as well... but it would be nice to get some data on what your output is here].

Oh -- and one other thing to try:

vparload -p -o -tm

I had to dig around to find Failsafe mode -- but that should bring up the kernel with your tunable settings ignored and the Failsafe values instead. Try that before adding memory as described below. (And if that doesn't work, show what did happen -- getting the options recognized by vparload sometimes seems to involve getting the command to realize what goes with -o and what doesn't... so it may be that we just need to get a "" around the -tm or something.

You add memory to a vPar using vparmodify. Since this is v2, the vPar will have to be stopped (which shouldn't be an issue).

vparmodify -p -a mem::

Where vpar is the target vPar and size is the amount in Mb you want to add [since you don't specify a Cell, that is ILM in the command]. The size needs to be a multiple of the granule size defined for your vPar environment.

vparstatus -A in another vPar will show you available resources (granule size and how much ILM is left).

[Kuekuatsheu]

Thanks. Succeeded in booting in failsafe mode. The OS advised us to removed the saved with the kconfig -d command but when we issued it, the OS returned that the command was not found. How do we reset the kernel parameters to the old values in failsafe mode. Please advise. Thanks again!

OWEN

[Don Morris_1]

Ok... failsafe comes up in Single user mode.

So you'll want to "mount /usr" first [as kconfig lives in /usr/sbin/kconfig].

Then I'd do just "kconfig" first -- to see which configurations you _do_ have. Look for one such as "GOOD" or "backup" or anything other than your current one. Then kconfig -n and reboot.

Your system should come up in _that_ configuration -- at which point you can do: kctune -c maxfiles= maxfiles_lim=
which will reset the tunables to the default for that configuration. Then kconfig -n and reboot... and you should be back to normal. Alternately, you could try a lower setting than 409600 but higher than the defaults -- but at this point I'd be more focused on getting your system back.

After you mount /usr -- you could try just kctune directly... but my v3 system in Failsafe has a long message about configuration changes not likely to be written to disk in failsafe mode, so I'd assume v2 is the same here. Safer to reboot to an alternate configuration (non-Failsafe) and make the changes there.

[Kuekuatsheu]

Thanks Don,

However, when we tried to mount /usr, the system returned that /usr is busy. Is there another way around this? Booted the vpar in LVM maintenance mode but the system would not boot also.

Owen

[Don Morris_1]

Do a "ls /stand" and note the directory names. Those are the configurations -- and you'd be looking for anything other than current, I would think. Assuming you find one, go back to "vparload -p -b /stand//vmunix" -- that should boot the alternate configuration with prior tunable values. At which point, you can kctune -c the other configuration to get back.

last_install would be a good one if it is there too.

[Kuekuatsheu]

We tried to boot from the last_install. Now, the kernel won't even boot in failsafe mode.

Owen

[Don Morris_1]

All with the same out-of-memory panic? (Which wouldn't make any sense unless last_install is the only real configuration... but that's not at all the default).

Console logs of the vPar booting from loading vmunix to the panic might help here.

[Kuekuatsheu]

[Don Morris_1]

Ah... ok.. so it swapped last_install into the current configuration, but last_install was installed as an nPar not a vPar (and there are missing kernel modules needed).

Do you still have the ls output of the available subdirectories under /stand? All we need to do is find one of your vPar configurations -- preferably not the one you were running, but if we must then you can get back to booting that in failsafe mode [one of the things Failsafe would have done is explicitly copy that configuration to a unique name it displayed on the console... so that must be there].

[Kuekuatsheu]

Ok. We booted from /stand/backup/vmunix and entered failsafe mode. We'll try to reset all kernel parameters to default with kctune.

Owen

[Kuekuatsheu]

Tried kctune and reset all values. Still won't boot. Can I recreate my /stand/vmunix using my backup kernel in /stand/backup/vmunix? Just to try and see if the system will boot.

This looks like the results of your other thread:

400K is way too big. Who needs that many open files/sockets?

[Avinash20]

If you are able to boot from /stand/backup/vmunix, then just copy /stand/backup/vmunix to /stand/vmunix and boot the system

[Kuekuatsheu]

just tried that. still won't boot. we issued kctune commands to change kernel parameters. but when we reboot, the problem still persists and when we check out the values after reboot, they did not seem to change.

here is the output of kctune -c current before and after reboot.
