On Power Machine with Ubuntu14.04.4, the above patch did not help to
resolve the parted command issue:
Installed package:
-------------------------
root at miglp2:~# dpkg -l|grep parted
ii libparted0debian1:ppc64el 2.3-19ubuntu1.14.04.2 ppc64el disk partition manipulator - shared library
ii parted 2.3-19ubuntu1.14.04.2 ppc64el disk partition manipulator
parted command shows ioctl fail message:
-------------------------
root at miglp2:~# parted -s /dev/mapper/mpath2 mkpart primary 20% 40%
Device /dev/mapper/mpath2-part2 not found
device-mapper: table ioctl on failed: No such device or address
Device /dev/mapper/mpath2-part2 not found
device-mapper: table ioctl on failed: No such device or address
As reported earlier, partx also fails:
-----------------------------
root at miglp2:~# partx -a /dev/mapper/mpath2
partx: /dev/mapper/mpath2: error adding partitions 1-2
root at miglp2:~# echo $?
1
Thanks,
Manju

Title:
ISST-LTE: parted command shows "device-mapper: table ioctl on failed:
No such device or address" error
Status in parted package in Ubuntu:
Fix Released
Status in parted source package in Trusty:
Fix Committed
Bug description:
[Impact]
Partitioning multipath devices after install always results in multiple error messages even though the devices get created.
[Test case]
Run the following command:
parted -s /dev/mapper/mpath1 mkpart primary 0% 20%
On a system where mpath1 is an extra unpartitioned multipath device.
[Regression Potential]
This should generally not adversely affect partitioning devices; the goal is to make sure parted correctly synchronizes with udev and multipath-tools so that device nodes are created at the right moment to satisfy what parted attempts to do, and that they are only created by udev, not automatically via device-mapper.
Since this only affects timing of device node creation and only in the
device-mapper case, where it already appears to be incorrect, there
should be no other effect than removing the error messages.

On Ubuntu14.04.4 while creating disk partition using parted command following error/message is displayed:
root at roselp1:~# parted -s /dev/mapper/mpath2 mkpart primary 0% 20%
Device /dev/mapper/mpath2p1 not found

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:

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 at 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 at 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 at roselp1:~#
root at 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 at 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 at roselp1:~# partx -a /dev/mapper/mpath1
partx: /dev/mapper/mpath1: error adding partition 1
root at 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 at 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 at roselp1:~#
Output of kpartx:
---------------------
root at roselp1:~# kpartx -a /dev/mapper/mpath1
root at 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 ?
