I am using 5.1B-4 with AdvFS on all filesystem.
I know I can use disklabel to change filesystem size on disk. But the server is a mission critical server and the shared disk is a SAN EVA6000. What tool I can use to reduce the size of the filesystem and guarantee not losing any data on the disk?
Thanks S

SolutionAnd that is the only way to do it online.
But you must have have license for Advfs utilities to be able to do it.
By the way, take a look at:

Re: Shrink filesystem size.
I am not sure how you can use rmvol to clean up my existing filesystem:
oracle_dmn#dev 1258291200 237680291 203818296 54% /u01
oracle_dmn#tst 1258291200 816097499 203818296 81% /u04
As this filesystem is currently used by oracle. I can't shutdown this production Oracle in anyway. How does rmvol can shrink a advfs filesystem size without losing its data?
Thanks
Sam

Re: Shrink filesystem size.
The rmvol command will remove a disk from a domain, and will sucess only if there is enough space on the remaining disks to hold all the data.
Maybe you have another options, what do you need to do? Why do you need to reduce the size of the file system? What is your goal?

Re: Shrink filesystem size.
The oracle_dmn only occupy one disk;
# showfdmn -k oracle_dmn
Id Date Created LogPgs Version Domain Name
45d8dee4.000742d6 Mon Feb 19 10:19:00 2007 512 4 oracle_dmn
Vol 1K-Blks Free % Used Cmode Rblks Wblks Vol Name
1L 1258291200 203818256 84% on 256 256 /dev/disk/dsk1c
I need to reduce its filesystem size because we are running out of disk space and the new TB storage disk is not arrived so soon. I need to reclaim about 400GB space from the current Oracle domain.
Thanks
Sam

Re: Shrink filesystem size.
oracle_dmn#dev 1258291200 237680291 203818296 54% /u01
oracle_dmn#tst 1258291200 816097499 203818296 81% /u04
There is not 400GB to clean here.
u01 and u04, are filesets dev and tst both from the same domain oracle_dmn, and the avaiabel space shown on each line is the same space presented twice.
There is a total 200GB free in the domain, not 400.
How do you intent to use that free space?
Why not just create an other fileset in the domain and use that mountpoint for the needed expansion zone?
fwiw,
Hein.

Re: Shrink filesystem size.
what Hein suggests, is a good idea. In case you need the files in a certain directory, you can create a link to oracle_dmn
Otherwise do you have another domain, where you can rmvol one partition temporarily? If so add it to oracle_fdmn, rmvol the partition you want to split, split it and addvol the reduced partition and then move the temporary partition back to its original place.
greetings,
Michael
