Re: best practice on increasing VG00 volume group and file systems
Its good option to save downtime because lot of copying would be completed while your system is running.
You will have to install rsync if not alreay installed.

Re: best practice on increasing VG00 volume group and file systems
Actually we have file systems like /oracle , /oracle/a , oracle/b and /oracle/c . What would be the proper steps to move only /oracle out of VG00 to non VG00? /oracle/a , oracle/b and /oracle/c file systems are already non VG00.

Re: best practice on increasing VG00 volume group and file systems
Then check its size with bdf, maybe there's not so much data in /oracle itself and a migration isn't worth to do.
Unix operates with beer.

Re: best practice on increasing VG00 volume group and file systems
Kapil mentioned ...
1. create a new filesystem with name /abc rsync it with /oracle.
2. shutdown oracle, rsync again (would take very lil time).
3. rename /oracle as /oracle_old and /abc to /oracle. Then start oracle.
4. remove /oracle_old from vg.
As I have /oracel/a , /oracle/b etc , how can I rename /oracle as /oracle_old as other file system will be impacted ? What should I do in this case?

Re: best practice on increasing VG00 volume group and file systems
Best practice is that only OS information go in vg00.
Oracle applications and such should be in their own volume group. Data should be in yet another volume group.
In this scenario, I would plan some down time, back up the applications. I would then set up a new volume group for them and logical volumes and file systems. Then I would restore the data.
You can't keep adding disks to vg00. Eventually it will exceed the size of a single tape and make recovery a difficult, if not impossible situation.

Re: best practice on increasing VG00 volume group and file systems
New volume groups and logical volumes are all ready. My question is how am I going to mount the new logical volume at /oracle without disturbing non VG00 /oracle/a , oracle/b file systems?
If I unmount /oracle , will the current logical volume data located @ /oracle show up in / file system?

Re: best practice on increasing VG00 volume group and file systems
"...how am I going to mount the new logical volume at /oracle without disturbing non VG00 /oracle/a , oracle/b file systems?..."
Stop oracle and all other applications or other processes on the file system.
Make a temporary mount point (* mkdir /temp_oracle *)
mount the new lvol under /temp_oracle
cd old file system
cp -p -r new file system
umount both old and new file systems
mount new lvol on old mount point.
cp /etc/fstab /etc/fstab_old
update /etc/fstab
repeat for all new lvols
Once verified in 2-3 days by users, lvremove the unneeded lvols out of vg00, thereby reclaiming the space.
Note: Until your database and application are back up and an actual write operation has taken place, or even for the first day of work, you can roll back to the old lvols. This should be presented as an option to mgmt and a point of no return determined. When you reach that point, lvremove as indicated above.

Re: best practice on increasing VG00 volume group and file systems
How can I copy the contents of just /oracle file system data to a new place without /oracle/a , /oracle/b file systems data?
