UNIX for Dummies Questions & Answers

Hi,
I need to copy all filesystem located on /dev/dsk/c1t0d0s0 to /dev/dsk/c1t0d0s3 which has more space (45Gig).

Here is the /etc/vfstab display:
# cat /etc/vfstab
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
#
/proc - /proc proc - no -
fd - /dev/fd fd - no -
swap - /tmp tmpfs - yes -
/dev/dsk/c1t0d0s0 /dev/rdsk/c1t0d0s0 / ufs 1 no -
/dev/dsk/c1t0d0s3 /dev/rdsk/c1t0d0s3 /adv1 ufs 1 yes -
/dev/dsk/c1t0d0s1 - - swap - no -

df -h display:
# df -h
Filesystem size used avail capacity Mounted on
/dev/dsk/c1t0d0s0 9.8G 8.1G 1.7G 84% /
/proc 0K 0K 0K 0% /proc
mnttab 0K 0K 0K 0% /etc/mnttab
fd 0K 0K 0K 0% /dev/fd
swap 1.0G 152K 1.0G 1% /var/run
swap 1.1G 24M 1.0G 3% /tmp
/dev/dsk/c1t0d0s3 57G 13G 43G 24% /adv1

Since /dev/dsk/c1t0dos3 has more space, i want to use ufsdump to copy OS to a new mountpoint here then put in backup somewhere in case of discaster may occurs.

Note: that /adv1 is the database and application in operation.

the prtvtoc /dev/dsk/c1t0d0s0 shows:
# prtvtoc /dev/dsk/c1t0dos3
prtvtoc: /dev/dsk/c1t0dos3: No such file or directory
# prtvtoc /dev/dsk/c1t0d0s3

Could someone help please step by step. I'm new to this environment.
I also noticed that ufsdump recommended in Single user Mode.

Thank you very much.

One thing that I'd recommend doing before going to all of this trouble is identifying what is taking all of the space on /

You may discover that you have an application that is storing data on this slice - the solution is to fix where the data is being written, rather than changing your root partition...

Hi,

I don't want to change my root partition. All i would like to do is having a copy of OS in case of emmergency...

Thanks
