move /var to new file system

[shatnawi]

Hi all ... hope all going will with you

OS : solaris 10
/var in my system is under / , and I want to move it to new file system , i appended new line in the /etc/vfstab file as the follwing
/dev/dsk/c2t1d0s0 /dev/rdsk/c2t1d0s0 /var ufs no yes -
when I rebooted the system the following message appeared
svc:/system/filesystem/minimal:default failed to mount /var

can anyone help me ... thank in advance

Have you created a filesystem on /dev/dsk/c2t1d0s0? Did you migrate the data from your existing /var directory on to the new filesystem?

Simply mounting it over the top of the old /var is not enough... it would also mean that no space would be released on your existing / filesystem because the old /var data would still be there, but hidden under a mount point.

assuming you have mirrored root drives.

the easiest way would be to break the mirror, repartition one of the disks to fit your necessary sizes and then do a live upgrade on to that new disk.

1. Boot in single user from a cd
Insert cd
boot cdrom –s

2. Mount your root file system.
I will assume that is /dev/dsk/c1t1d1s0.
mount /dev/dsk/c1t1d1s0 /a

3. Create a new file system for /var
format
Select the disk you want to use.
Create a partition of the size you want.
I’m going to assume that is /dev/dsk/c1t1d1s3
Remember to label the disk.

4. Create a new file system on the /var disk slice.
newfs /dev/dsk/c1t1d1s3

5. Mount the new var partition (anywhere will do)
mount /dev/dsk/c1t1d1s3 /b

6. Copy the data in the old var directory to the new var file system.
cd /a/var; tar cf - .| (cd \b; tar xfBp -)

7. If you are sure everything has copied over to /b, delete your old data.
/bin/rm –r /a/var/*
Keep the directory /a/var.
This is the mount point for the new file system

7. Edit /etc/vfstab on your root partition.
This is mounted on /a.
vi /a/etc/vfstab

The entries for root and var will look something like this:

/dev/dsk/c1t1d1s0 /dev/rdsk/c1t1d1s0 / ufs 1 no -
/dev/dsk/c1t1d1s3 /dev/rdsk/c1t1d1s3 /var ufs 1 no -

8. Cross your fingers.

9. Reboot on the original root file system.

10. df –k to check. You should see something like this:

/dev/dsk/c1t1d1s0 20646121 5524089 14915571 28% /
/proc 0 0 0 0% /proc
mnttab 0 0 0 0% /etc/mnttab
fd 0 0 0 0% /dev/fd
/dev/dsk/c1t1d1s3 10332460 651767 9577369 7% /var
swap 14901952 192 14901760 1% /var/run
swap 14907168 5408 14901760 1% /tmp
etc

Good luck.
