Comments on Migrating an LV from one VG to another IBM Power Systems and the Like 2012-02-09T11:39:08Z http://ddpwr.com/2012/02/migrating-an-lv-from-one-vg-to-another/feed/atom/ WordPress By: Anthony English Anthony English https://www.ibm.com/developerworks/mydeveloperworks/blogs/AIXDownUnder/?lang=en http://ddpwr.com/?p=123#comment-8 2012-02-09T11:39:08Z 2012-02-09T11:39:08Z Very good post and beautifully laid out – very readable. Perhaps it’s worth pointing out that when you move a logical volume to a new volume group, the file system must not be in use.

If you’re migrating within a volume group (to different Physical Volumes), then you ought to be able to do it online using commands like mklvcopy and rmlvcopy, or just migratepv.

But this post is about moving out of rootvg. I agree – I’ve always found it good practice to give rootvg the space it needs and keep data file systems in other volume groups.
