My /stand filesystem is full on one of my servers. I have created an ignite archive of vg00 excluding some filesystems, and want to use it to increase /stand.
My question is:
Are all filesystems still going to be intact after using the archive to increase /stand, or will I have to restore the excluded filesystems from backup?
Solved! Go to Solution.

SolutionFrom where did you exclude the filesystems in question? Ignite will re-create vg00 and the filesystems _you_ specified for it.
Good practice says that vg00 consists _only_ of the standard logical volumes (lvol1-lvol8) created during a cold-install.
In cases like that, you could let Ignite re-import your non-vg00 filesystems or perform the operation yourself (with 'vgimport').
Regards!

Re: Question about Ignite Restore
stand,swap & root lvols are contiguously allocated.
Example:
if /stand currently is 1GB and swap is 4GB, Increase the /stand to 1.5GB and reduce the swap size to 3.5GB.
These modifications can be done while restoring the archive image from the ignite server, choose the advanced installation option and change the size.

Re: Question about Ignite Restore
if you have a fresh backup, why do not try to extend your root filesystem online ?
it is not dangerous if you have a backup and you will win time.
some documentations on how to do it:

So If I understand correctly, I would need to restore the excluded filesystems from backup.
The reason I am trying to extend /stand is due to the error I received below when trying to install Fibre Channel driver on the server.
ERROR: Although the increase on the filesystem for the resulting new
kernel might be enough, building it, requires additional disk
space for the temporary kernel and the object files.There is
not enough disk space available on filesystem "/stand" to
allow creation of temporary files. You must free at least 135
Kbytes on this volume.

Re: Question about Ignite Restore
Instead, did you check the /stand contents and see anything that you can delete ? Sometimes I have seen people keeping 4 different copies of vmunix.prev ? 135K should not be that hard to clean up unless you are running a very tight ship with no room to spare. Clean up your /stand from junk if you can and schedule the restore from ignite approach to a weekend or a holiday as a proactive maintenance if you ask my opinion.

Re: Question about Ignite Restore
This is pretty simple.
You make an Ignite archive.
You boot off the archive and use the intervention prompt to restore and change the size of the /stand file system as part of the system restore process.
Then you restore non vg00 data and you are are done. You may not if careful not even need to restore anything else.
It is a BASIC Ignite function.

Re: Question about Ignite Restore
I couldn't agree with more. Finding 135K shouldn't be that hard to find. But I have always been leiry about removing anything from /stand. I did a search for some obvious files that could be removed, however nothing stood out to me. Maybe there is something I can remove but just being paranoid about it.

Re: Question about Ignite Restore
All the File Systems that have been excluded will have to be recreated from the lvol level and restored.

You may want to delete it or move it else where.

Out of this list, the file sizes of /stand/vmunix and /stand/current/vmunix are strikingly same. Run a diff against these two files and if they are the same, you can move /stand/current/vmunix to a different filesystem, to give you the temporary breathing room. Upon successful completion of a newly compiled kernel, it will be replaced by this new kernel and you do not have to move back the /stand/current/vmunix into original place, instead just delete it. If it does not, i.e., problems in kernel compilation, you can always refer back to this copy after booting to a recovery media and copying it back to its original place.
Hope this helps

Re: Question about Ignite Restore
Just a final bit of advice.
/stand is a single purpose file system. The only information that needs to be there is what is required to compile a kernel.
The files on stand if they are not being regularly used to boot the system can be stored elsewhere. HP-UX 11.11 still requires /stand to be HFS, but the files are not damaged by being stored elsewhere.
You can avoid the difficulty of ignite rebuilding your system with a few decisions on what you really need to boot your system off of.
I mean lets say you have a special kernel for running oracle all by itself, does it really need to sit in /stand or can it sit elsewhere and be moved into position just prior to reboot.
