Hi Mig28mx,

if you can confirm that the issue is present when the second PATH is active, probably your problem is the compatibility of linux native multipath with the storage system.

For example, if your Storage Array is a HighEnd ( EMC VMAX, HDS VSP, DS8000), normally, the multipath daemon is fully compatible with default settings.

However if you Storage is a midrage (EMC VNX, HDS HUS or AMS), you need write special settings inf the multipath.conf. You need review the notes about of this setting in the User Guide of the Storage Array.

If the issue continue, I think that you need review the SAN Switches in order to see if the error counters in the fibre ports are growing.

If you can share with me the model of switches and storage I can be more precise.

NAME

       filesystem - event signalling that filesystems have been mounted

SYNOPSIS

       filesystem [ENV]...

DESCRIPTION

       The  filesystem	event  is  generated by the mountall(8) daemon after it has mounted all filesystems listed in fstab(5).  mountall(8) emits
       this event as an informational signal, services and tasks started or stopped by this event will do so in parallel with other activity.

EXAMPLE

       A service that wishes to be running once filesystems are mounted might use:

	      start on filesystem
