vg07 does not show up in /etc/lvmtab

Hi!

 

I have an entry missing for vg07 in lvmtab.  I can see entry in fstab but not in lvmtab. /app File system is mounted on it. I can see it from SMH but I amhesitant to import it as it requires a new VG name. 

 

$bdf

/dev/vg07/lvol1    62898176 12433242 47328205   21% /app/oracle

What do I do so it gets added to lvmtab? Any advice?

 

Thanks

Re: vg07 does not show up in /etc/lvmtab

Can you please post the output of "strings /etc/lvmtab"?

 

Since the LV is mounted and vgdisplay and lvdisplay are working correctly, I wouldn't do anything drastic.

Re: vg07 does not show up in /etc/lvmtab

What disk(s) comprise VG01 (your 'vgdisplay' doesn't show the disks -- try 'vgdisplay -v vg07')?  Did it get renamed at some point?

Re: vg07 does not show up in /etc/lvmtab

Please post

 

 

# lvmadm -l

 

(lower case L)


Hope this helps!

I see the problem in the bottom of the output. Can I change the version # while file system is up and running?

 

Thanks

Re: vg07 does not show up in /etc/lvmtab

I wouldn't.  I don't see that having the VG as a version 2.0 VG is a problem.  Just something to keep in mind.

 

Also, information for VGs that are version 2.0 and greater is stored in the /etc/lvmtab_p file.

Re: vg07 does not show up in /etc/lvmtab

Version 2.x volume groups are not listed in /etc/lvmtab; this is normal. They are listed in /etc/lvmtab_p instead.

 

Version 2.x volume groups can have higher capacity/less overhead than version 1.0 volume groups, so it's actually a good thing.
