Perhaps, or I notice a strange parameter in zpool attributes :
drbdpool  failmode                       wait                           default

failmode = wait ? That's something that could lead the DRBD stack not beeing
informed of the zpool failure.

So, 2 more things to test as soon as I have finished the horringbly long list of
performance parameters.

Best regards,
