It looks like you already created the physical volumes. What does pvs display?
It's not totally clear what you are asking, but if I understand, you want to "combine" the disks /dev/sdb and /dev/sdc. You can do this in as much as adding them to the same volume group.
You can then create three logical volumes, one each for /u01, /u02 and /u03
i.e.
Then you can create the filesystem using the LV's.
(far from optimal, but quick for me to show...)

Hello,
I need explanations about physical disks and physical volumes. What is the difference between these 2 things?
In fact, i am trying to understand what the AIX lspv2command does.
Thank you in advance. (2 Replies)
I was in smit, checking on disc space, etc. and it appears that one of our physical volumes that is part of a large volume group, has no free physical partitions. The server is running AIX 5.1. What would be the advisable step to take in this instance? (9 Replies)

Hello,
I have logical volume group of 50GB, in which I have 2 logical volumes, LogVol01 and LogVol02, both are of 10GB.
If I extend LogVol01 further by 10GB, then it keeps the extended copy after logical volume 2. I want to know where it keeps this information

Hi!
Can anyone help me on how I can do a basic check on the Unix filesystems / physical volumes and logical volumes?
What items should I check, like where do I look at in smit? Or are there commands that I should execute?
I need to do this as I was informed by IBM that there seems to be... (1 Reply)

Hi guys,

Hi,
I am new to unix. I am working on Red Hat Linux and side by side on AIX also. After reading the concepts of Storage, I am now really confused regarding the terminologies
1)Physical Volume
2)Volume Group
3)Logical Volume
4)Physical Partition
Please help me to understand these concepts. (6 Replies)
Hello everyone,
I just read that while creating a logical volume(LV) we can choose the region of the physical volume (PV) in which the LV should be created.
When I say region I mean: outer edge - outer middle - center - inner middle and inner edge.
Can anyone help me understand the utility... (11 Replies)

o2image(8) OCFS2 Manual Pages o2image(8)NAME
o2image - Copy or restore OCFS2 file system meta-data
SYNOPSIS
o2image [-r] [-I] device image-file
DESCRIPTION
o2image copies the OCFS2 file system meta-data from the device to the specified image-file. This image file contains the file system
skeleton that includes the inodes, directory names and file names. It does not include any file data.
This image file can be useful to debug certain problems that are not reproducible otherwise. Like on-disk corruptions. It could also be
used to analyse the file system layout in an aging file system with an eye towards improving performance.
As the image-file contains a copy of all the meta-data blocks, it can be a large file. By default, it is created in a packed format, in
which all meta-data blocks are written back-to-back. With the -r option, the user could choose to have the file in the raw (or sparse) for-
mat, in which the blocks are written to the same offset as they are on the device.
debugfs.ocfs2 understands both formats.
o2image also has the option, -I, to restore the meta-data from the image file onto the device. This option will rarely be useful to end-
users and has been written specifically for developers and testers.
OPTIONS -r Copies the meta-data to the image-file in the raw format. Use this option only if the destination file system supports sparse files.
If unsure, do not use this option and let the tool create the image-file in the packed format.
-I Restores meta-data from the image-file onto the device. CAUTION: This option could corrupt the file system.
EXAMPLES
[root@node1 ~]# o2image /dev/sda1 sda1.out
Copies metadata blocks from /dev/sda1 device to sda1.out file
[root@node1 ~] o2image -I /dev/sda1 sda1.out
Use with CAUTION. Copies meta-data blocks from sda1.out onto the /dev/sda1 device.
