Package: multipath-tools
Version: 0.9.4-3
Severity: wishlist
Hi,
after installation multipath-tools does not work properly in order to activate
mapping for devices automagically after the boot.
I finally figured out that
multipath -t >/etc/multipath.conf
generates an initial configuration which is usable, but for a
find_multipaths "strict"
which is the least friendly way of defining mappings and
practically prevents any auto-mapping (wwids need to be provided by hand).
While that is a perfectly working setup if properly manually configured, for
sure it is
not the easiast setting to cope with IMHO.
The final result, for instance, is that LVM could catch all single devices at
boot
and the proper multipaths maps result broken, with the admin not familiar with
multipathd inners lost in the dark.
A very simple configuration such as:
defaults {
user_friendly_names yes
find_multipaths yes
}
and a round of update-initramfs after that, gives a proper working
implementation, with
LVM perfectly capable of coping with variable names at boot time.
Note that RH folks provides a mpathconf script and an initial template
in /usr/share/doc/device-mapper-multipath-0.4.9/multipath.conf for that.
