Community Forum > XFS Continuous Pool Replication

Hello:

Where does one set up the continuous pool replication ? I have defined a storage pool as XFS but cannot see how one replicates that ?

Thank you.

Hello Phil,

Pool level Replication using XFS and DRBD has been deprecated. We found that the old DRBD / XFS Pool Replication solution was not used by customers in production due to slower replication performance in comparison to our newer DR replication features that replicated at the individual Storage Volume and Network Share level.

Official removal of DRBD / XFS Pool replication was in the QuantaStor 3.14 release: http://wiki.osnexus.com/index.php?title=QuantaStor_Version_ChangeLog#v3.14.0.6993_.28December_30th_2014.29_REBOOT_REQUIRED

Storage Volume/Network Share level replication also provides data archive capabilities with snapshot retention which was something that was not possible with the older replication solution. Details on Storage Volume/Network Share replication is available here:
http://wiki.osnexus.com/index.php?title=QuantaStor_Administrators_Guide#Volume_.26_Share_Remote-Replication_.28Disaster_Recovery_.2F_DR_Setup.29

If you are looking for File Storage that has HA failover with multiple copies of data on different hardware, this is possible with our scale-out File Storage solution. Details on the Scale-out File Storage features of QuantaStor are available here:
http://wiki.osnexus.com/index.php?title=QuantaStor_Administrators_Guide#Managing_Scale-out_NAS_File_Storage_.28GlusterFS.29_Volumes

We also recently introduced initial support in QuantaStor 3.14 to provide Scale-out Block level storage using Ceph. Ceph allows you to serve SCSi Target LUN's from redundant block level storage with multiple copies of the data on different systems. If you are interested in the Ceph Solution I mentioned, please email sales@osnexus.com to indicate your interest and join our Ceph pilot Program.

Hi Chris:

GFS scale out is good, but does the solution support Geo-Replication as could not see that in the docs.

Thanks, Phil

Hello Phil,

Our Scale-Out NAS File Storage does not yet support Geo Replication. However, it is on our RoadMap to add in the future.

Thank You,
