On Ubuntu14.04.4 while creating disk partition using parted command following
error/message is displayed:
root@roselp1:~# parted -s /dev/mapper/mpath2 mkpart primary 0% 20%
Device /dev/mapper/mpath2p1 not found
device-mapper: table ioctl on failed: No such device or address
Device /dev/mapper/mpath2p1 not found
device-mapper: table ioctl on failed: No such device or address
Even though mpath2p1 is created , Device /dev/mapper/mpath2p1 not found
error is shown:
root@roselp1:~# lsblk /dev/mapper/mpath2
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT

Steps to recreate:
-------------------------
1. Install Ubuntu14.04.4 on a PowerVM lpar with multipath disks.
2. Create partition using parted command: parted -s <mpath device> mkpart
primary 0% 20% ----> This shows "device-mapper: table ioctl on failed" ,
even though partition is created.

For getting "udevadm monitor -p" output , I had to create one more partition
and whose output is :
root@roselp1:~# lsblk /dev/mapper/mpath2
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
mpath2 (dm-2) 252:2 0 20G 0 mpath
??mpath2p1 (dm-12) 252:12 0 4G 0 dm
root@roselp1:~# parted -s /dev/mapper/mpath2 mkpart primary 20% 40%
Device /dev/mapper/mpath2p2 not found
device-mapper: table ioctl on failed: No such device or address
Device /dev/mapper/mpath2p2 not found
device-mapper: table ioctl on failed: No such device or address
root@roselp1:~#
root@roselp1:~# udevadm monitor -p
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

Thanks Chandan..
Tried fdisk and partx which are part of "util-linux"
1. fdisk creates partition without any error message:
------------------------------
root@roselp1:~# fdisk /dev/mapper/mpath1
Command (m for help): n
Partition type:
p primary (0 primary, 0 extended, 4 free)
e extended
Select (default p): p
Partition number (1-4, default 1): 1
First sector (2048-41943039, default 2048):
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-41943039, default 41943039): 4096
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
WARNING: Re-reading the partition table failed with error 22: Invalid argument.
The kernel still uses the old table. The new table will be used at
the next reboot or after you run partprobe(8) or kpartx(8)
Syncing disks.
2. partx FAILS to add the dev mapping of the newly created partition:
----------------------------------------------
root@roselp1:~# partx -a /dev/mapper/mpath1
partx: /dev/mapper/mpath1: error adding partition 1
root@roselp1:~# lsblk /dev/mapper/mpath1
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
mpath1 (dm-1) 252:1 0 20G 0 mpath
To Create device maps after partition creation, we will have to relay on GNU
packages: partprobe or kpartx
Output of partprobe :
-------------------------
root@roselp1:~# partprobe /dev/mapper/mpath1
Device /dev/mapper/mpath1p1 not found
device-mapper: table ioctl on failed: No such device or address
Device /dev/mapper/mpath1p1 not found
device-mapper: table ioctl on failed: No such device or address
root@roselp1:~#
Output of kpartx:
---------------------
root@roselp1:~# kpartx -a /dev/mapper/mpath1
root@roselp1:~# lsblk /dev/mapper/mpath1
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
mpath1 (dm-1) 252:1 0 20G 0 mpath
??mpath1p1 (dm-21) 252:21 0 1M 0 part
Just with "util-linux" tools (eg, fdisk, partx), partition creation and device
maps fails. Only way to get the dev map for the partition created is to relay
on GNU tools: partprobe OR kpartx.
Does util-linux's partx required to be fixed ?
