Systemd-udev-settle timing out
This document (7022681) is provided subject to the disclaimer at the end of this document.
Environment
SUSE Linux Enterprise Server 12 SP2
Situation
4 ibmvfc npiv devices assigned but only 3 paths show up instead of 4 in the multipath output.
Resolution
Increase timeout for the kernel command line parameter.
rd.udev.event-timeout=300
Steps to add option:
1. Append option in the file /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT= rd.udev.event-timeout=300
2. grub2-mkconfig -o /boot/grub2/grub.cfg
3. reboot
Note:
rd.udev.event-timeout helped in this case but is seldom helpful in other cases.
rd.udev.event-timeout=300
Steps to add option:
1. Append option in the file /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT= rd.udev.event-timeout=300
2. grub2-mkconfig -o /boot/grub2/grub.cfg
3. reboot
Note:
rd.udev.event-timeout helped in this case but is seldom helpful in other cases.
Cause
The default rd.udev.event-timeout=180 seconds was causing a timing issue where systemd-udev-settle timed out.
