How will the two FC7 systems detect the new drive?
Is there a method to the madness?
This is why we use disk labels or UUIDs instead of device names. With
changes like this in the kernel and especially with machines with
removable drives, or machines using fancy multipath storage, it's
nearly impossible to reliably predict exactly what order the drives
will be found in.
So the solution is: just give the partitions names instead. Then it
doesn't matter if your FC6 root drive is sda1 or sdb1 or hdc1, it's
always LABEL=fc6_root. If you say "mount LABEL=fc6_root /fc6" it will
Do The Right Thing.
So, in short, it doesn't matter how the two FC7 systems will detect
the new drive, so long as you give it a useful label.
Will, you could have mentioned:
1. a command to set the label ?
2. whether an lvm label like LogVol01 or LogVolhome is the same as the
label you are mentioning ?
Consider it either good or bad that a long time redhat/fedora user
does not know such a command - it gets set by the installer - for
actual partitions, but not? for LVM logical volumes ?
After much searching "label lvm partition" etc in google with little
result, I stumbled across the mkfs.ext3 parameter -L volume-label, but
decided that would actually format the partition.
tune2fs -L yourlabel /dev/yourdevice
