Need to do LVM Upgradation

[Vidhya B]

Hi all,

We have LVM 1 version currently. We are facing issues because of the default number of PEs. We are planning to upgrade to LVM 2. I am not aware of the method to be adopted. Kindly tell me the steps which are involved in the upgradation.

Thanks in Advance!!

You can convert them with vgversion, e.g.

# vgversion -V 2.1 vg01

see vgversion whitepaper and man page for details.

Thank you!!

Will this work for all the OS Versions? I have heard that some patches are required for upgrading.

Kindly help.

This works with 11.31 only. The versions 2.0 and 2.1 came with a later update release - best to update (update-ux) the existing 11.31 installation to the latest update release.

Hi,

Thanks a lot for your replies.

Few of my servers are running on 11iv2. Is there anyway I can upgrade that to LVM 2? Will it support?

Kindly help me. Thanks!
