problem with multipath since I upgraded form etch to lenny

[Johan <johan.arens@gmail.com>]

Hi

I have a problem with my multipath setup since I upgraded a server
from Etch  to Lenny.

One of my paths doesn't show up anymore.

The command multipath -v6 gives me those 2 errors :
libdevmapper: ioctl/libdm-iface.c(1623): device-mapper: reload ioctl
failed: Invalid argument
SAN_ess5Disk1: domap (0) failure for create/reload map

Any idea ?

Do I have something wrong in my config ?


Thanks a lot

Johan
