[linux-lvm] restoring lvm cinfiguration

[Lars Grobe]

Hi!

This is somehow a followup to my message describing the (my) resize-error.

I took a look at vgcfgrestore, and it seams to be the right tool for me now
;-) But before I apply this to the ruins of our filesystem.... Am I right if
I suppose the /etc/lvmconf/vgname.conf to be the current configuration (so,
the wrong one after my lv-shrinking)? So that vgname.conf.1 is the previous
one, that I should restore? I need lvm to allocate the same space on the pvs as
it did before, so that I can rebuild my reiserfs with fsck.

Thank You, CU, Lars.

Hello Lars,
here it worked with /etc/lvmconf/vg01.conf.

Hi! 

My question is concerning the naming conventions of the files. So is vg01
the name of your vg?

I did a vgcfgrestore -l with the different files in /etc/lvmconf, and while
the <vgname>.conf gives me the current config (that is after resize, and I
want to get the config before resizing), I have a file <vgname>.conf.1.old that
seams to hold the data before resizing.

So I would like where lvm will store the data if I resize a lv - is .conf
the new (current after resizing) and .conf.1.old the old (before resizing)
configuration? So if I want to undo resizing, should I restore from .conf.1.old?

Thank You, CU, Lars.

Yes.

I think you should use .conf.1.old then. The newest file is .conf, the
oldest one .conf.9.old (at my system, "ls -l" shows you this).
You can use the -t option to test the command.

Yes, that's correct.

You can even have deaper backup histories setting the environment variable
LVM_VG_MAX_BACKUPS to a higher value than 9 (max is 999).

It worked fine here! Thank You!
