Hi Paul, Tks for your advice. cat /etc/fstab dev/VolGroup00/LogVol00 / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 devpts /dev/pts devpts gid=5,mode=620 0 0 tmpfs /dev/shm tmpfs defaults 0 0 /dev/VolGroup00/LogVol01 /home ext3 defaults 1 2 proc /proc proc defaults 0 0 sysfs /sys sysfs defaults 0 0 /dev/VolGroup00/LogVol02 /tmp ext3 defaults 1 2 /dev/VolGroup00/LogVol03 swap swap defaults 0 0 * * * end * * * d use if there was any free space. > Unmount /tmp and remove/comment out the fstab entry for it.

If I understand your advice correctly /tmp will be automatically created on / (LogVol00) during reboot. > Once you're happy that that's working, you can delete LogVol02 from > your > volume group: I'll not delete LogVol02 and will use it to install 2nd Linux OS. Also I'll create a 5G partition on raw partition as its /home /boot will be shared by 2 OS.

That is my mistake. This is my first time using LVM. After successful completion I'll have 2nd round, wiping out the whole HD. However this is a little bid pitty because it took me sometime to install FC5_64. There were lot of problem before running "yum update" Either the mouse pointer or the PC hung. It is quite stable now. Others noted with tks. B.R. SL
