Package: multipath-tools-boot
Version: 0.4.8-10
Severity: critical
Justification: breaks the whole system
I've got a system with QLogic ISP2432 Fibre Channel card which I was
trying to boot from a multipathed /. Unfortunately multipath-tools-boot
was unable to boot the system, as it takes a while for the LUN to appear
on the system, so it is available only after /sbin/multipath was ran.
So there were no devices created in /dev/mapper/ and the system was unable
to boot, since it was set to use /dev/mapper.
I think, that /sbin/multipath shouldn't be ran only once during the system
start, but it should be triggered whenever a new device is discovered
(since initrd will wait for a root device to appear this would work nicely).
As a quick workaround I've added the following line:
echo 'ACTION=="add", SUBSYSTEM=="block", KERNEL=="sd[a-z]",
RUN+="/sbin/multipath"' > $DESTDIR/etc/udev/rules.d/z60_multipath.rules
to /usr/share/initramfs-tools/hooks/multipath and I've rebuilt initramfs.
This fixes the problem for me.
