VG backup file

[Rick Garland]

Hi all:

HPUX 11.23 on rx4640 systems.

Seems that when VGs are created the /etc/lvmconf/vgxx.conf is not created.

I have been used the VG conf backup file being created in the /etc/lvmconf directory. But it is not happening here. Or anywhere for that matter.

So when I do the 'vgcfgbackup -u' command it fails. Easy enough fix, take off the '-u' switch.

But why aren't the VGs being backed up at VG creation time?

Hi Rick,

It does not seems to a situation except that either the files was manually removed physically or some other location was specified for files let us say /tmp from where they got washed out by themselves alongwith routine cleanups.


It could be possible that the files perhaps do not get created while creating VG but instead get created /updated everytime LV chnages are made.Also there is a switch to bypass this backup file creation/updation option along with all lv related commands.

HTH,

Hi Rick,
Looks like a local machine issue. I checked lvmconf folder on a rx2600/hpux 11.23 and conf files are created/updated.

Most probably someone removed your conf files.

There are multiple LVs under each VG so I would expect that there be multiple backups of the vg conf. Not multiple copies, but multiple backups.

Using the defaults for VG/LV creation so there should be backups for all VGs made.

I will research the switch that would turn this off. I am unaware this switch existed so I need to find out.

This is happening on multiple ia64 systems and I am not removing them.

Question, would MCSG have an impact in this situation? We have MCSG 11.16.

Just went through patch analysis and got clean bill of health. But still that doesn't account for everything we might see.

Any other possibilities?

Move this to top.

Still investigating

No answers. Have made a work around.

Check the existing/active VGs on a system and verify its existence in /etc/lvmconf.

Give me some breating room to continue the research.

Thanks for the responses.
