More than one device on a host

[Oezcan Acar]

That was actually my question: how detects mogilefs the device on the storage node? In my case  I added to mogstored.conf 

docroot=/database/mogdata

and created with mkdir -p /database/mogdata

After this operation device list output was:

dev1: alive      1.618   462.119 463.737

Mogilefs was able to detect the device on the storage node. After that I added the second device on the same storage node. Device list showing:

dev1: alive      1.618   462.119 463.737
dev2: alive      0.000   0.000   0.000

How mogilefs now knows on which disk dev2 resides?

thanks.
