So, unless > there's another user I missed it's not been tested. Multipath can be tested quite easily with a loopback scsi target, you don't require specialized hardware. The easiest way to do this would probably be the built in LIO target + open_iscsi initiator. I haven't attempted running this current version of the patch series but I haven't run into issues with bcache+multipath in the past. > >> >> Thanks. >> >> -- >> tejun > -- > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ -- CTO | Orion Virtualisation Solutions | www.orionvm.com.au Phone: 1300 56 99 52 | Mobile: 0428 754 846 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
