lvextend

I found some free extents on my root disk, so I expanded /var,opt and usr. All went well. Do I have to worry about the mirrored root disk. Or does my lvextend on the primary root volume also automatically take care of the mirrored root disk.

Hi,

If your lvols are mirrored, your lvextend will be picked up on the mirror disk also. You can verify this by doing an 'lvdisplay -v' on the lvols that you extended.

Hi Robert,

You're covered. You can verify that by looking at the lvols with lvdisplay. You'll see that the current LE amount is half the allocated PE - the other half is your mirror.

If an LV is mirrored, then lvextend will automatically extend both copies. You don't have to worry about the mirror.

I'm sure you are aware the just lvextend'ing will not give you the space in the filesystem. You need to use either the fsadm (if you have Online JFS installed) or the extendfs (without Online JFS) to extend the filesystem and make the new space available to you.

Hi Robert:

You're fine. Extending a mirrored logical volume means that all copies are extended.

MirrorUX will take care of you if you set it up correctly.

lvdisplay -v will certainly tell you. Just look for the following in the output.

--- Distribution of logical volume ---

The disks in the lvol will be listed afterwards.
