        Is there a way to use flockler against a generioc iSCSI SAN?
      • wallnerryan
        hi _markh_, today we do not support a generic iscsi blockdevice driver. However most of our backends support iscsi. Could I ask what your usecase is for using generic iscsi support?
      • _markh_
        wallnerryan: We have a SAN (Dell MD3820i) attached via iSCSI to four servers
      • we're wanting to run Swarm on those and be able to migrate conatoners between servers
      • so we're currently scratching our heads as to teh best way forward

      • if we simply attach targets to the servers, can flocker migrate persitent storage from a 'local' disk to one attached to another

      • wallnerryan
        unfortunately not, flocker needs to understand how to detach and reattach volumes from backends.
      • We do have Dell SC series integration, so I wonder if the MD3820i (powervault right) is on the radar
      • _markh_
        yep. Powervault
      • can it (flocker) migrate persitent data by copying?
      • wallnerryan
        flocker doesnt touch the data path today, so we dont copy, replicate, etc any data. Rather we provide automation for volumes when the container moves
      • so there would need to be a driver for generic iscsi as you mentioned or for powervault
      • you could reach out to the team behind the Dell flocker drivers and see if they would be interested in powervault driver development
      • I will make sure we (clusterhq) record it in our records. Could I ask a little bit about the use-case for using powervault with docker?
      • djx joined the channel
      • _markh_
        Isn'' that driver for SC devices not Powervault?
      • wallnerryan
        yes, but I think you can reach out to Sean McGinnis the developer on that project to see about other Dell Support, possibly powervault.

        I'll contact Sea and find out. I was looking at the demo at https://plugins-demo-2015.github.io/ which seems to imply flocker is able to migrate/copy local storage in some way. The initial diagram
      • implies that at least
      • or did I miss something...
      • wallnerryan
        oh, yes that use case uses ZFS
      • but, ZFS is experimental and there are bugs
      • in that case, ZFS does move data bits, but we recommend using our supported drivers

        Ah OK. Well, it was worth checking. Looks like flocker won't work for us at the moment...
      • lewq
        _markh_: curious to know what you're trying to achieve? Stuff we're working on might work for you soon...
      • ah, you described it above, sorry :)
      • _markh_
        we'd love you if it didf :)
      • did
      • Hmmm it seems the MD series has VMWare VAAI support - does that help?
      • wallnerryan
        _markh_: , if you can back vsphere with MD then in thoery you can you the vsphere flocker driver yes. VAAI lets you provision storage devices from MD in vsphere correct?
      • though, I'm not sure they configuration has been tried before, so would be interested if you did wind up trying it out

        _markh_: If you get a chance, I'd love to hear more about the use case behind actual movement of data rather than just mapping the LUNs to different nodes using shared storage.
      • The use case you described above, unless I'm missing something, sounds like a perfect fit for what Flocker can do already, provided you can find a driver that can communicate with your platform.
