Summary: Extending a UFS filesystem

Thanks for all the quick responses.  Most folks said that I should use
growfs.  However from what I gathered from the man page, growfs does a
write-lock on that filesystem that I wanted to grow, which pretty much
prevents users from writing to that area.  So while it might work, it
wasn't a solution we could use.  
 
We gave the dba's the disk space the old fashioned way.  We brought
down the app, copied the data to a temp area, wiped out the 15 gb lun,
created a 65 gb lun then copied the data back in.  
 
Thanks for all your help.
 
Cheers,
 
Jim

Admins,

I need some immediate help if at all possible.  I've been directed to
add 50+gb to our DBA's filesystem (/u03) on my v440 running Solaris 9.

We don't have Veritas volume suite so this filesystem was created
using
the native UFS commands in Solaris 9.  This filesystem is 15 gb in
size
and it is mirrored.  There is approximately 53 gb'sish left (see
format
output below).  You guessed it, we can't take /u03 down at this time,
it
has to be after hours.  

Is there anyway to extend /u03 from 15 gb to 65 gb's w/o on the fly,
similar to online jfs does in the aix and hp-ux world?

Thanks for your help as always!

Cheers,

Jim
