Hi!

Which archives are used to configure or to modify the LVM?

Thank'S!

an easy way to change LVM stuff is to use SAM -> disk and file systems.

You question is far from clear. The actual configuration data are stored in the the LVM disks themselves. The data necessary to restore the LVM metadata are created by the vgcfgbackup and are stored, by default, in /etc/lvmconf. There is also a binary file, /etc/lvmtab, that contains LVM data. You can partially examine its contents via "strings /etc/lvmtab". Essentially all of the commands that begin with "vg", "pv", and "lv" are used to create or modify LVM related structures. Start with "man vgcreate, pvcreate, and lvcreate" and the man pages themselves will point to the other commands.

Yes, but...lvmtab? inetd.conf? inittab....

it does not intervene?

Thanks

I say all about this why I can not mount any LVOL....

Re: LVM files

A. Clay Stephenson — Fri, 31 Mar 2006 11:14:15 GMT

LVOL's are not mounted; filesystems which might be housed on an LVOL are mounted. However, I think you may need to activate the volume group.

e.g. vgchange -a y /dev/vg01

Man vgchange for details.

Can you see any files in /dev/vg01 directory?
I guess you have exported your /dev/vg01.

find the map file and go an import
vgchnage -a n /dev/vg01
vgimport -m /dev/vg01 /dev/dsk/cxtydz
vgchangy -a y /dev/vg01
mount -a
chan

Post the output of this command:

vgdisplay -v /dev/vg00

and it's easier if you simply cut and paste the text rather than a screenshot.

Thank's!

Look the screen shot.

Re: LVM files

Daniel Caçador — Fri, 31 Mar 2006 11:59:27 GMT

I stay using the web console, only screen shot...sorry

Re: LVM files

A. Clay Stephenson — Fri, 31 Mar 2006 11:59:57 GMT

I said vgdisplay -v /dev/vg00 and DO NOT use a screenshot -- copy and paste the output itself into your posting -- as text. I need the complete output and also do an ls -l /dev/vg00 and post that.

Re: LVM files

Daniel Caçador — Fri, 31 Mar 2006 12:38:30 GMT

Sorry....I try but via web console has don't possible to mark the text and paste..

Very sorry...

But if you want to know about the lvol's..Yes, all OK.

Please, look the sreen shot off ls -l.

Thank's

Re: LVM files

A. Clay Stephenson — Fri, 31 Mar 2006 12:48:24 GMT

Okay, I see your problem:

Under /dev/vg00 your greoup file has minor device number 0x010000 this means that all the LVOL device nodes must begin with 0x01 as well but yours begin with 0x00. Normally, vg00's group files uses 0x000000.

Re: LVM files

Daniel Caçador — Fri, 31 Mar 2006 12:51:27 GMT

Thank's!!

How I fix this problem?

Very thank's!

Re: LVM files

A. Clay Stephenson — Fri, 31 Mar 2006 13:00:53 GMT

The easist approach is cd /dev/vg00.
rm group
mknod group c 64 0x000000

sync; sync

reboot

Re: LVM files

Daniel Caçador — Fri, 31 Mar 2006 14:07:25 GMT

Don't work...

What I can do now? See de screen shot..

Thank's

Re: LVM files

A. Clay Stephenson — Fri, 31 Mar 2006 14:15:59 GMT

It worked; you now have another problem. You need to edit /etc/inittab and comment out all of the entries that begin with "ems" and issue an "init q".

Re: LVM files

Daniel Caçador — Fri, 31 Mar 2006 14:34:54 GMT

I only can boot in single user mode (-lm), but don't have text editor...(like vi, ed, sed...).

How I edit this text?

Thank's Very very Thank's!
