how to rebuild /etc/lvmtab

[Joe Profaizer]

Do I just move /etc/lvmtab to a different file, then run vgscan?

Thanks for you help.

Hi Joe:

Try this:

# mv /etc/lvmtab lvmtab.old
# vgscan -v

Hello,

From the man pages..
If the /etc/lvmtab file exists, the information
contained in the file is used to assist in rebuilding the file, but
the existing file is updated with the new corrected configuration.

I get the following error message:
vgscan: Couldn't access the list of physical volumes for volume group "/dev/vg00
".
Physical Volume "/dev/dsk/c0t2d0" contains no LVM information

/dev/dsk/c0t2d0 is my dvd.

#strings /etc/lvmtab displays:

/dev/vg00
i9-u
/dev/dsk/c1t2d0
/dev/dsk/c2t2d0

Is everything OK?

Yes.. Don't worry about the character on top of strings output.

Hi Joe


Yes everything is fine. mv /etc/lvmttab to .old file and do a vgscan -v -p and you are good to go.

Hi Joe (again):

1) The vgscan output is normal with DVD and CDROM devices. Just ignore it.
2) The strings command of lvmtab also is normal. The reason is that the lvmtab is a binary file and the strings command is looking for ASCII strings in that ! If you don't have problems while booting or activating VG, then you can ignore it.
