I have a question, I have to for performance reasons move storage from one disk to another( EMC)
Now I have a live database on a file systems which has a 40 GB Physical Volume.
Now I plan to add a new 40GB disk ( A high Qaulity of Service disk from SAN) to the system and create a PV. and then add it t the Database Volume Group and then do as follows
pvmove OLDPV NEWPV
Would this work fine and I suppose I would not need a downtime for Database,please correct me if I m wrong.
The following are the logistic details
Server - VM server
OS - Red Hat Enterprise Linux ES release 4 (Nahant Update 5)
Kernel Version - 2.6.9-55.ELsmp
LVM version : LVM version: 2.02.21-RHEL4 (2007-03-26)
Library version: 1.02.17-RHEL4 (2007-02-02)

Any guidance would be highly appreciated.
