During installation I tried to retain an empty primary partition for
LinuxOS to test multi-boot without success. It needed a mount point
therefore I was compelled to create /tmp.
Now I want to move /tmp back to FC5_64 / and use its space for / of
another LinuxOS and repartition with LVM the unallocated space creating
a partition of 10G for its /home. Please advise how to proceed. TIA
Unmount /tmp and remove/comment out the fstab entry for it. Reboot. Your
system should come up OK with /tmp on the root filesystem (the /tmp
directory already exists).
Once you're happy that that's working, you can delete LogVol02 from your
volume group:
# lvremove VolGroup00/LogVol02
That will give you some free space in VolGroup00 that you could use for
a second OS install, albeit not a raw partition.
Besides is there any way to create an empty primary partition at time
of installing FC5_64, without mounting it
Just leave some free space on the disk and then you can create new
partitions as and when you need them. Your /dev/sda has only two
partitions on it, so that's effectively two more primary partitions you
could use if there was any free space. Unfortunately you have an LVM
physical volume using up all of your free space and there's no clean way
of shrinking that, so you'll probably need to use the same volume group
for your second install.
