[TriLUG] Problem with LVM

[Brian McCullough]

Sorry to be late coming into this thread -- I was out of town and out of 
contact with the list ( dial-up at best ).


Tom,

What I am seeing is a very common issue with your type of installation 
-- you need to modify your lvm.conf file to "hide" the two components of 
the md0 "drive" from vgscan.

In that file, you will find "filter" clauses, one of which looks like:

filter = [ "r|/dev/cdrom|" ]

If you add another that looks something like: ( I don't remember your 
two drive specifications just at the moment )

filter = [ "r|/dev/sda3|", "r|/dev/sdb7|" ]

That should help your vgscan issues.  As far as the difference between 
/dev/VG/LV and /dev/mapper/VG-LV, as David says this is a version 
difference, and usually doesn't matter because the kernel seems to be 
able to accept both forms.  Check your /dev/ directory after vgscan runs 
successfully and see which form exists, and change your fstab to match.

Incidentally, I know this is a "teach your grandmother to suck eggs", 
but LVM _is_ starting at boot, correct?
