Any multipath SAS support in Linux?
I'm thinking about trying to setup a two node HA storage cluster connected to an external SAS box. Is such a thing possible at this time?
TIA,
Orion

I've had success with aic94xx + dm_multipath before. There has recently been a bug in the multipath tools wherein it fails to detect disk type due to the removal of a "bus" attribute in sysfs. and I don't know if that's been fixed. (Aside from building your own with the sysfs part removed....)
Note that success == I set it up, started I/O, yanked some cables, and it kept chugging. :)
