Re: [linux-lvm] Cannot unmount my /usr partition.....



Ah cool!

Thanks Heinz!

That worked.....apparently some stupid admin *cough*me*cough*.....forgot to put
on the -a flag when cp'ing from the old usr partition to the LVM usr
partition....

Heh. Just another thing to watch out for, boys and girls, when performing an
LVM enhancement to a pre-installed machine.....better way to do it would probably
have been to just tar the whole thing up and untar it to the freshly mounted /usr
directory...but hindsight is always 20/20 right?

Doing the lsof|grep /usr >/root/lsof.output in the /etc/rc.d/init.d/halt script
right before the / partition was remounted read-only gave me an output file I
could then use to see what the major malfunction was...and now I am happily
rebooting with green across the board..

Thanks again!

I now have a completely working LVM/Reiser/DevFS machine going :)

Now if only I could resize my / partition (2GB that I could use for
LVMing......there isn't a way to get the / directory as LVM is there?????) I
would be in happy-camperland..

Till the next time I screw things up and needlessly bother developers about it :)
