extend filesystem

Need to know how/if to extend filesystem to new space made available from san. For example, have filesystem /dev/sdf1 mounted on /u02 that has 247G space but need 500G more. Client has made available another 500G from san and now we're not sure how to extend u02 to include the additional space.

Thanks for the great answer but I can't get anymore space. So, I thought I should be able to mount the new disk as /u03 and create symbolic link for directory /u02/oradata/appn to point to /u03. Datafiles for the database are the major consumers of space and they live under /u02/oradata/appn/<dir 1,2,3,etc>

I have run fdisk on /dev/sdg and created partion 1 as /dev/sdg1 fine, I then ran mkfs.ext2 on /dev/sdg1 and it seemed to run fine, though I was a little confused as it looked like it was prompting me for response but before I could figure out what to enter it completed.

I then ran e2label /dev/sdg1 /u03

I then added line to fstab as :
LABEL=/u03 /u03 ext3 defaults 1 2

But when I run mount /u03 I get "mount: mount point /u03 does not exist"

df -h shows no /u03 filesystem either.

Have I missed something?

Ok, figured out I hadn't created the u03 directory yet. Works now, I just need to do some testing.

Ultimately I did not use this answer but it helped me a great deal and was excellent otherwise.

Thank you.

:) Yeah I would just ask if you'd created the mountpoint. Just take your time. I hope everything goes well with you :)
