Since your PV is flakey (failing), probably the best way is to convert the LV to linear first and then converting back to mirror with a new PV. A failing PV should make the system convert to linear LV if you have right software (works on RHEL based system). Or you can do the following steps manually. First step may not be necessary, but it should not cause any harm in your case. 0) Run vgcfgbackup to back up your LVM metadata. This is needed if something goes wrong. You have been warned. If you know, this data is already there in archives... 1) lvconvert --mirrorlog core <LV-name> 2) lvconvert -m0 <LV-name> <Failing-PV-name> Make sure this did remove the PV you wanted. If not, use vgcfgrestore to restore and ask for help... 3) Insert your new disk, create PV label on it, and add it to your VG 4) Run "lvconvert -m1 <LV-name> <New-PV-name> 5) If you need "disk" log, run another lvconvert to get disk log. Hope this helps, --Malahal. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
