[linux-lvm] badiane: Problem

[linux-lvm] badiane: Problem

[gdurand]

I have created five volume groups (vg0 - vg4) to hold respectively /var,
/home, /home/music, /usr, /usr/local.

I started with a 500MB / partition then created the pv, vg and lv.  Now what
I wanted to know is how to have the system reboot and have the partitions
mounted properly since the lvm binary and library cannot be found properly.
The libraries are in /usr/lib/lvm and should be in /lib and the binary in
/sbin or /bin.

The install is from the debian binaries.  I can't compile on my system
without getting a seg fault (that's another story.)  So I'm thinking that I
would have to move the libraries to /lib and hope that the system will find
them upon boot and proceed without errors.

I would like to know the proper way to do this.

Oh!  I had mounted the lv's on temp mount points /var2/, /home2/ etc and
copied the original's data over and umounted so that upon remount they would
again be avail able.

Thanks in advance.

On my redhat system, I had to build LVM into the kernel ... but I had to fix
the Segmentation fault you talked about.  Search the archives for that one
... it's a compiler issue.

Just as an FYI - this is a very bad setup.  You should have 1 (or maybe 2)
VGs set up for these filesystems.  For a normal system, having a single
VG is far more flexible.  You can then "share" all of the unused PEs and
add them to whatever LV needs them.  If you have separate VGs, then you
are not much better off than having DOS partitions.

I would also suggest that you create these LVs as small as possible.  On
Debian in particular, you can have /usr almost 100% full, and only extend
it as necessary to install new packages.  Same with /home and /home/music -
give yourself a "reasonable" amount of free space in each, and leave the
rest unallocated, so you can add it where it is needed later.

Cheers, Andreas
