I was afraid you were going to say that.
Go back to single user mode.
mkdir /new_var
cd /mnt/raid/var
tar cf - . | ( cd /new_var ; tar xvf - )
Make sure both dirs look the same.
Change the link to /new_var. Or remove the old link & mv /new_var /var.
reboot.
Toby, Thank you for this nice tip. It worked perfectly. The server is
back in the game again.
Just for my learning experience, I would appreciate if you clarify one
point though. Why are you afraid when you hear /mnt/raid/var symlinked
to /var? Is something wrong with it?
Here is my fstab:
/dev/md2 / ext3 defaults
1 1 <--- md2 Software RAID1
/dev/md1 /boot ext3 defaults
1 2 <--- md0 Software RAID1
/dev/md0 /tmp ext3 defaults
1 2 <--- md1 Software RAID1
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
LABEL=SWAP-sda3 swap swap defaults,pri=1 0 0
LABEL=SWAP-sdb3 swap swap defaults,pri=1 0 0
/dev/raid_vg0/raid_lv0 /mnt/raid ext3 defaults
0 0 <--- Hardware RAID10
Before, home and var were under /mnt/raid directory and symlinked to
/home and /var. Now, both directories were copied to / (md2 software
RAID1) as new_home and new_var and /home and /var symlinks are now
pointing to these new directories. /mnt/raid (hardware RAID10) which is
the main storage of my server is not being used at the moment.
I am planning to have 2 logical volumes (for home and var separately)
instead of 1. Then, they will be mounted as separate partitions as /home
and /var to /dev/raid_vg0/raid_lv0 and /dev/raid_vg0/raid_lv1,
respectively. Is it a good approach? Please advise.
Thank you again.
Mufit
