Hi All,
I was playing with my linux machine for RHEL preparation. I dont know where i left it last time before going to leave :-). Now the system is up and I cant take risk to reboot the machine.
Now if i give the command
# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
145G 133G 4.8G 97% /
/dev/sda1 145G 133G 4.8G 97% /boot
none 501M 152K 501M 1% /dev/shm
Strange thing is /dev/sda1 is mounted on /boot which is 100MB in size but if you see above its showing the specs of / into /boot
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
145G 133G 4.8G 97% /
same
/dev/sda1 145G 133G 4.8G 97% /boot
whats wrong with this ?
when I check the contents of /boot fodler it is empty.
# ls /boot
it gives nothing. and prompt to same place where it was (mean empty).
Please see the more outputs that can help

Mean: I can see the file and its contents in grub menu by
(grub> cat (hd0,0)/grub/grub.conf ) but nothing in /boot folder out of grub menu.
# cat /etc/grub.conf
cat: /etc/grub.conf: No such file or directory
# ls /boot/
# still nothing in this folder
Another interesting thing I cant move the mounted directory to somewhere with different or same name, what i checked on other system but here it works
# mv /boot/ /root/boot
[root@example /]#
That make sense that it wasnt mounted properly in last bootup. but I am not sure.
I have to recover it without reboot. Can any one help and sort it out?
Please do let me know if you need more outputs.
Many thanks.
Cheers.
