The process varies upon whether or not you have OnlineJFS installed.

1) lvextend -L larger_size /dev/vg02/lvol3
2) If you have OnlineJFS, execute fsadm -F vxfs -b newsize /myfilesystem
If you do not have OnlineFS:
a) umount /myfilesystem
b) extendfs -F vxfs -s newsize /dev/vg02/rlvol3
c) mount /myfilesystem

Man lvextend, fsadm_vxfs, extendfs_vxfs for details. I assume this is a vxfs filesystem if not look for the corresponding hfs commands.

Hi Hari,

Depends a bit on if you do don't have OnlineJFS installed.

Without OnlineJFS.

# umount /filesystem
# lvextend -L new_size_mb /dev/vgxx/lvoly
# extendfs -F vxfs /dev/vgxx/rlovy
# mount /filesystem

With OnlineJFS

# lvextend -L new_size_mb /dev/vgxx/lvoly
# fsadm -F vxfs -b "new_size"M /dev/vgXX/lvolXX

Shalom,

Well you need to have the current size of the file system, because both lvextend and fsadm require you to submit not how much you wish to increase the file system size by, but what new total you desire.

Even if you don't have Online JFS, you can replace the fsadm step with extendfs if you umount the file system first.

Now I want to extend the below mentioned filesystem.
_________________________________

$ df -k /u01/app/oracle
/u01/app/oracle (/dev/vgtivoli/lvol2 ) : 15352112 total allocated Kb
2048056 free allocated Kb
13304056 used allocated Kb
86 % allocation used

_________________________________

So I am executing the below commands to extend the filesystem by 5gb, please confirm wheither it is right.

$ lvextend -L 5gb /dev/vgtivoli/lvol2

and then

$ fsadm -F vxfs -b 5gb M /dev/vgtivoli/lvol2

Please verify and comfirm me ASAP

Thanks

# lvextend -L 5120M /dev/vgtivoli/lvol2
and
# fsadm -F vxfs -b 5120M /u01/app/oracle

[Patrick Wallek]

NO NO NO.

You must put the NEW SIZE of the file system on your lvextend command line.

Doing:

# lvextend -L 5120
will just make the filesystem 5GB if it is SMALLER than that.

It appears as if you file system is currently approx. 15 GB in size. You said you want to extend by 5GB, so that would make it 20GB.

What you need to do is:

# lvextend -L 20480 /dev/vgtivoli/lvol2
and
# fsadm -F vxfs -b 20480M /u01/app/oracle
