Hello,
I'm using a 2.4.18-ac3 kernel and the multipath module in order to ensure
automatic IO path failover. The systems connect to a FC SAN environment.
New logical disks are added/removed from the SAN periodically.
Unfortunatelly, linux's raid subsystem uses major and minor numbers in the
superblock in order to identify members for all raid types - including
multipath. This causes the multipath module to fail when attempting to
identify the members. When the scsi driver is loaded, the bus is scanned and
all the available devices/targets/luns are added to the scsi subsystem and
are allocated a major and minor number.
you mean autodetection fails? don't use autodetection.
regards,
Luca.
