Hi Neil,
There is a few of us out here that are using the great mdadm multipath feature, however we are having problems with the failback on repair / replug of paths.
Also we've seen situations where both paths to devices are active & sync, is this correct or should one be active & sync and the other be standby ( I suppose active-active or active-standby is what I'm getting at).
Is there any chance you could help us out with this or maybe show us where we are going wrong in the config of this feature?
Please have a look at the following URL for our issues:
