RAID on OpenStack
Hi, I don't find any openstack API to RAID feature. Is it missing on purpose? How can the user ask to implement RAID 1/2/5/6... ? Thanks, Amir
First time here? Check out the FAQ!
Thanks for your fast replay, Could you please describe (in high level) the path from the user command (PUT) a file until it is written to a HDD? How the IT man configures the disk parameters? Is it part of the openstack? Many thanks, Amir
If you are speaking about the Cinder backend, this is not something that Openstack will probably ever implement or accept.
The Cinder backend itself should be setup as redundant. Then when users request space on the block device they don't need to know about those things. They can be confident thier data is redundant.
Now you may have a user want to do something like attach two Cinder volumes from different availability zones and RAID them. That might work, I haven't tested that scenario. But at that point the RAID would be handled inside the instance itself.
What would a "RAID" feature in Openstack look like to you? Perhaps we can suggest a way to accomplish that.
