thanks for your replay. I have noticed that in your case the "old" disk has faild, but in my case the new disk faild. That means that the disks of the old LVM are all woring ! No bad Blocks or so. But SMART told me that one device will fail in future. So i put that bad disk in (i testet it befor - it showed no error).
My first atempt to get everything back working was to remove the device, throw it out of my hw-array config and boot. Well,i think pvmode tries to access this device , but it is no longer availible !
I have another disk that is bigger than the drive that faild. Does pvmove worke again if i put that drive in its place and start pvmove again ? Perhaps i have to mark the partition on the disk as lvm bevore, but is there a chance that pvmove just continues ? By the way how do i tell pvmove to continue ?
