I want to add a mirrored device to a volume group.
So I've created a mirrored md (/dev/md0) and activated it. It shows into /proc/mdstat.
When I want to add it using system-config-lvm the device is not shown into the unused devices list. Using tools I can give /dev/md0 and initialize it but it still does not show into the unused devices list.
So if I add this device to my volume group using the command line it works, vgdisplay shows me there are 2 PV, the original one and md0, but that's all, pvmove fails (the VG is not the boot vg) and worse, at every reboot, the system complains there is a missing drive into this vg, etc....
So I wonder if it is possible to use a mirrored device into LVM ?
All help will be greatly appreciated !
