yes, udevd runs:
service boot.udev status
Checking for udevd: running
Here the beginning of my /etc/multipath.conf file:
defaults {
udev_dir /dev
path_grouping_policy multibus
getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
prio "alua"
user_friendly_names yes
default_features "0"
}
blacklist {
devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*|sda"
}
multipaths {
multipath {
...
}
}
this version of the multipath tools is installed: multipath-tools-0.4.7-34.40
