pvmove

[sodapop]

Hi,

I want to move my lvol on vg00 to vg01. vg00 is residing on the local disk and vg01 on SAN. My question is if I do a pvmove will my lvol automatically be a part of vg01? Thanks in advance.

best regards,
carlo

from the man page

" pvmove - move allocated physical extents from one LVM physical volume to other physical volumes"

physical volumes must be in the same volume group!

Backup your data and restore them to the new lvol.

Note:

Don't move OS core directories like /etc /opt /var ...

[Siju Vadakkan]

pvmove is possible only with in the VG only

[psreedhar]

what exactly is your purpose? why you want to move a LV from root volume group?

[Anshumali]

I hope not..
pvmove uses same code as mirror-ux and only possiblility is to move the extents on the disk in the same VG online.
As your target is different VG, its best to make a backup and restore it there.
Also, excercise caution whenever you decide to use pvmove as incomplete pvmove will result in stale extents.

Hi,

The main purpose is transfer all the data files that are located on an lv on vg00 to a space on SAN but will be on a different vg (e.g. vg01).
