[linux-lvm] vgcfgrestore and bootstrap

[linux-lvm] vgcfgrestore and bootstrap

[Gingia]

Hi all.
I write in this list to explain the problem with the meta data and the 
inconsistence.

Thank to Heinz J . Mauelshagen i solve the principal problem.

Now i have another problem caused by the same root.

When i start the devlopment  server (debian woody), it remain in the runlevel 
1 e ask me the pass to root access for device-filesystem problem.
It said that it had problem with the  lvm.

To start the sewrver i must to :
1) vgcfgrestore -n volume1 -f /etc/lvmconf/volume1.conf /dev/i2o/hda3
2) vgchange -a y
3) mount -a 
 and only now i can go to runlevel 2 for normal start.

So i understand that 1) the "restoring" metadata is a routine operation at 
boostrap instead of a propely restoring 2) for some reason this does not 
happen more.

So my question is: Why ?
How i can restabilished this at boot time? I can move to solve this other 
problem?
Can you help me?

Gingia,

the normal procedure is "vgscan ; vgchange -ay ; mount -a"
rather than vgcfgrestore before vgchange.

vgscan recognizes changes in the IO configuration (e.g. devices moved
to different addresses causing device nodes t change).

Have you tried "vgscan ; vgchange -ay ; mount -a" before ?
(keep in mind, that vgscan needs space below /etc/ to store metadata copies)

I controlled the script of bootstrap  to see if there is the apropiated entry, 
and it seems is ok, i also re-started the server .
I  tried "vgscan" and i have the output:
invalidate :dirty buffer 
invalidate :busy buffer  
(any time)
vgscan -- "/etc/lvmtab" and  "7etc/lvmtab.d" successfully created 
vgscan -- WARNING: this programm doe not do a VGDA backup of your group

after i do :
vgchange -ay 
and the output was:
vgchange -- no volume group found 

so i made the restore:
vgcfgrestore .........
the ouptput was 
vgcfgrestore -- VGDA for "Volume1" successfully restored to phisical volume 
"/dev/i2o/hda3" 
vgcfgrestore  -- you may not have an actual backup of restored group "volume1"

then i can do  vgchange -ay  and go on 

This is all , was it the matter?

Thank you

Can you send the "vgscan -d" output of this case to me directly, please
(mge@sistina.com) ?
Probably some i2o devices scanning flaw.

I tried to make a backup with 
vgcfgbackup command but it failed and the output was :
vgcfgbackup -- ERROR: VGDA in kernel and lvmtab are NOT consistent; please run 
vgscan

Can i solve this?
How i can solve the problem of bootstrap? If possible?
