** Description changed:
[Impact]
- * In certain hardware configurations, dasdfmt fails to format a drive,
+ * 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]
- * On a system with FBA and ECKD devices, perform dasdfmt
+ * 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.
+ * 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.
