Subject: [PATCH] fix(multipath): disable user_friendly_names with mpathconf
|
|
|
|
If dracut is creating /etc/multipath.conf by calling mpathconf in either
|
|
multipathd-configure.service or multipathd.sh, there is a chance that
|
|
the multipath config in the real root differs. Specifically, it might
|
|
have chosen different user_friendly_names for the devices. When the
|
|
systems switches to the real root, multipath may not be able to switch
|
|
the devices to their configured names because those might already be
|
|
in use. To avoid this, call mpathconf with "--user_friendly_names n"
|
|
to create a multipath.conf with user_friendly_names disabled. If all
|
|
devices use WWID names, it is always possible for multipath to rename
|
|
them later.
|
|
|
|
Fixes b8a92b715 ("multipath: add automatic configuration for multipath")
|
|
|
|
(cherry picked from commit f36f2869859eb5f9613a94a28dfaf31505e645cc)
