Local disk partitions are not created at boot time on multipath-blacklisted devices in RHEL 6
Issue
- Disk partitions are not created at boot time for local storage with a single path
- System panics on boot as it can't find the root logical volume or partition on the local storage device.
- When my local device is blacklisted by vendor/model in
/etc/multipath.conf
, partitions do not get created, or are created and quickly removed. - Running a partprobe after boot brings partitions back
- We updated the kernel and now the system won't boot.
Environment
- Red Hat Enterprise Linux (RHEL) 6
device-mapper-multipath
prior to release0.4.9-64.el6
- Devices blacklisted in
/etc/multipath.conf
by vendor/model, for example:
blacklist {
device {
vendor "DELL"
product "PERC H700"
}
}
