Here is an update with my findings of today. Paths to R2 LU are flaged read-only upon detection, as can be seen with "hdparm -r". hdparm is able to flag them rw (hdparm -r0). Once paths are switched to rw, I still can't use multipath to load maps upon them. But, issuing "blockdev --rereadpt" on the paths finally resolves this issue. I'm confused. What is expected from the multipath tools there ? I'd like to have the multipath maps up and running for R2 LU, for them to be ready the moment they get activated by the R1/R2 split. But I'm not sure how to do that in the described context. Input welcome. Regards, cvaroqui -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
