** Description changed: + [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. + + ---- + == Comment: #0 - Manjunatha H R <[email protected]> - 2016-01-19 03:02:12 == 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 mpath2 (dm-2) 252:2 0 20G 0 mpath ??mpath2p1 (dm-12) 252:12 0 4G 0 dm - root@roselp1:~# ls /dev/mapper/mpath2* /dev/mapper/mpath2 /dev/mapper/mpath2p1 - uname -a: -------------- root@roselp1:~# uname -a Linux roselp1 4.2.0-23-generic #28~14.04.1-Ubuntu SMP Thu Dec 31 13:41:19 UTC 2015 ppc64le ppc64le ppc64le GNU/Linux - multipath packages installed: -------------------------------------- root@roselp1:~# dpkg -l|grep multipath ii multipath-tools 0.4.9-3ubuntu7.7 ppc64el maintain multipath block device access ii multipath-tools-boot 0.4.9-3ubuntu7.7 all Support booting from multipath devices - parted packages installed: ----------------------------------- root@roselp1:~# dpkg -l|grep parted ii libparted0debian1:ppc64el 2.3-19ubuntu1.14.04.1 ppc64el disk partition manipulator - shared library ii parted 2.3-19ubuntu1.14.04.1 ppc64el disk partition manipulator - Steps to recreate: ------------------------- 1.
