I've just set up my first RAID 5 array and LVM2 volumes on a Debian Linux 
(sarge) system. We do backups from another machine in our network using 
Amanda. In trying to add this LVM machine to our backup scheme, I've run

These are mounted on (/export) :

drwxr-xr-x   6 root root 4096 Sep  7 23:00 home1
drwxr-xr-x  23 root root 4096 Sep  8 10:36 home2
drwxr-xr-x   3 root root 4096 Sep  7 15:06 home3

So it seems that I need to change the LVM device partition permissions. I 
couldn't find anything about this on the web, so I thought I'd ask here if 
this is the right thing to do and if there are any issues or problems I'll
