No

nas4free 9.1.0.1 under ESXi cannot handle physical RDM (raw device mapped) hard drives, but 9.0.0.1 can.
Trying to use such drive causes error as like "(da1:mpt0:0:1:0): unsupportable block size 0"

    I'm guessing your actually meaning virtual RDM where you create a linking file object to a local hard drive vs a fiber channel connected disk which would be physical RDM.

    I saw the same issue under the Paravirtual controller. It does work for me under the SAS controller.

    I'm guessing this bug definitely caused by FreeBSD SCSI/CAM subsystem behavior, it handles RDMs pretty good in earlier nas4free builds.

    First I thought there is a problem with the RDM in ESXi using a 3TB drive.

    But now I can confirm this bug with NAS4Free 9.1.0.1.636. and 9.1.0.1.306.

    I was giving 9.1.0.1.724 a spin and ran into this same bug. I'm using 2TB drives with RDM in ESXi 4.1.
