Hi guys, According to http://drbd.linbit.com/users-guide-9.0/s-dual-primary-mode.html, DRBD-9.1 will support multiple primaries. I am wondering if it can also enhance the auto reovery from split brain. It seems that currently we don't have a good solution of recoverying from split brain without data loss when dual primary is configured. I think it will be good to have a policy to merge all up-to-date data. I am considering to build a storage pool by aggregating remote drbd volumes into a VG and then any client can write to LV created in the VG. This solution can remove the limitation of single host's storage capacity when thin provisioning is enabled. If thin-provisioning is enabled with drbdmanage, the new-added storage servers can't help the node which runs out of storage space. That's why I care about the case of multiple primaries. Thanks for any feedback! -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.linbit.com/pipermail/drbd-user/attachments/20160301/49c3ea64/attachment.htm>
