Matching subscriptions: Ubuntu 16.04 Bugs https://bugs.launchpad.net/bugs/1582728 Title: DASDFMT fails with a buffer overflow error Status in Ubuntu on IBM z Systems: Fix Committed Status in s390-tools package in Ubuntu: Fix Released Status in s390-tools source package in Xenial: In Progress Bug description: [Impact] * In certain hardware configurations, dasdfmt fails to format a drive, thus preventing successful installation and/or initialisation of a new disk. "there is a bug in the parsing of /proc/dasd/devices which is being triggered only if an FBA device is listed prior to the ECKD device in question. And since you've had FBA devices attached to your system during the installation, you ran into that bug." [Test Case] * Activate on a system and FBA device and a ECKD device * Check that FBA device is listed first in /proc/dasd/devices * Try to dasdfmt the ECKD device with $ dasdfmt -t /dev/dasdX * One can change ECKD to "FBA " in /proc/dasd/devices by bind-mounting an edited file in place to reproduce the bug [Regression Potential] * Minimal. Bug fix cherrypick from upstream. [Original Description] During installation, either through the menu or in an ssh session , dasdfmt fails with a buffer overflow error and does not format the dasd volume. The volume is a z/VM minidisk - defined as 1 to end, this is common in this environment. The DASD volume was formatted from z/VM as a minidisk volume. These are the same steps taken for other distributions running under z/VM. I've attached some screen shots.
