Keith, Yes clvm is running.
Here is what I have done. 1) LUN assigned to the cluster nodes 2) multipathd detected the LUNs in all nodes 3) used GNU parted to create EFI/GPT 4) DID: kpartx -a /dev/mapper/mpath13 , then I see mpath13p1 5) pvcreate /dev/mapper/mpath13p1 6) vgcreate -c y prd_vg10 /dev/mapper/mpath13p1 7) Ran kpartx -a and partprobe in all nodes 8) lvcreate -n prd_vg10_lv -L2197GB prd_vg10 Error locking on node prd2: device-mapper: create ioctl failed: Device or resource busy Error locking on node prd3: device-mapper: create ioctl failed: Device or resource busy Error locking on node prd1: device-mapper: create ioctl failed: Device or resource busy Failed to activate new LV. Thanks Paras.
