For sure you will be able to mount /var on your new disk....
Thank you very much for it.
but not before you boot single user and copy all the contents across manually and then modify /etc/fstab to reflect the new location of /var.
If I boot from single user mode and copy /var directory to new
hardiisk, What will happent to permissions?
you need to copy everything with the same permissions. rsync, tar cpf,
... should do, as already suggested.
Then, What should I do to /var directory on OLD HardDisk. Should I
leave it alone or Should I rename it or Should I delete it?
you will need /var to mount the partition of the second hard drive. so
the contents of the "old" one should be moved out of the way (mv or
whatever).
It is possible to move to the new var without rebooting. you must stop
all services that use /var (lsof |grep /var ... etc) to be able to
unmount it. if the box is near you, rebooting is a lot simpler though.
Remember, Curently / and /opt and /boot and /swap are MOUNTED. i.e
/var is under / partition.
here is my /etc/fstab
[root@gateway root]# cat /etc/fstab
LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
LABEL=/opt /opt ext3 defaults 1 2
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/sda2 swap swap defaults 0 0
/dev/sda3 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom udf,iso9660
noauto,owner,kudzu,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0
In my experience it is nigh-on impossible to *move* /var when a system is running.
Noted.
Hint : next time use LVM *even* if you only have 1 physical disk to start with. It makes this sort of situation an non-event.
Yes , I aggree with you.
