Symptoms

Using fdisk(8) to create an LVM disk partition (type 8e) on a newly-created multipath device such as /dev/mpath/mpath0 generates the following message:

# /sbin/fdisk -l /dev/mpath/mpath0

Calling ioctl() to re-read partition table.

WARNING: Re-reading the partition table failed with error 22: Invalid argument.
The kernel still uses the old table.
The new table will be used at the next reboot.


Running partprobe(8) has no effect on this.
