Antwort: Re: [linux-lvm] MultiPath

[Dietmar Stein]

Hi

Follow documentation / sample raidtab for multipathing, which comes with
raidtools. If you've done that, both paths should be used (we have tested
this once and it was working, also the failover of the active path).

Otherwise I would say there's a misconfiguration.

I got the MD device setup in raidtab I am using the "multipath"
personality... It is not utilizing both paths though... I started a
write, then pulled the active path to simulate failure, and it just died
:) fun fun... thanks for the help!
