Solaris

Hello.
When I use format command - It shows:

/dev/dsk/c0d0s4 is normally mounted on /u02 according to /etc/vfstab. Please remove this entry to use this device.

What does it mean?

Check if the disk is mounted under /u02 by running 'mount | grep /u02'. The message given by the format command is just to alert you to the fact that the disk is mounted. You should not be modifying a disk that is mounted under any filesystem.

If you want to make any changes on the disk, unmount it using 'umount /u02'.

Thank you pal - Its clear now :-) There is another small query:

I have got 2 FileSystems visible when I use df -k or mount command /u00 and /u02 of 5 GB and 10 GB respectively. Can you please let me know exact commands to execute for below:

1) Delete /u00
2) Modify /u02 from 10 GB size to 5 GB size
3) Create /u01 (new fs) of size 10 GB

Thank you!

It depends on whether you are using a volume manager or not, and if you are, which one you are using. Can you post the output of df -k?

I am not using volume manager and installed solaris using CDs by inserting one by one 5 CDs. When CD1 was inserted - I had created filesystems /u01 and /u02 for 5 GB and 10 GB respectively. I then looked into some websites and FAQs and did below:

1) ran format command
2) created a new filesystem /dev/dsk/c0d0s8 using newfs command which wasnt visible in df -k command. Appended this entry in /etc/vfstab and mounted the filesystem. Which is also now available when i see df -k

My questions now are:
1) Where do we assign the size of new filesystem while being created. I did not find any option
2) How do I know that a new filesystem can be created (How Big?)
3) How to change the allocated size of any filesystem?
I am now trying to install oracle, inserted the CD and copied .zip file to newly created filesystem /u02 having space of 10G. Created new user oracle under group dba. renamed .zip file .jar and ran tar-xvf - Which is the file to install oracle in it? In the manuals I see they ask to run ./runInstaller - But I am not able to find it?

Thank you in advance for your reply.
