I have a lab consisting of 3 machines connected with 2 10gbe links on 2 segregated networks. Each device has 100tb in block storage connected to it. I want to use ATA over Ethernet to create a storage cluster which can be accessed from all the machines at one time. I want to do this from both the client and initiators at the same time.
I want to be able to mount the target file system on multiple initiators. I do not need to write to the filesystem from multiple systems at once, but I do want to read from the file system from many at once. I have thought about creating cache devices, though i would like to avoid this if possible. I know this is a rather complex problem, but I feel like i'm missing something, as it seems like what I want should be possible. I have been playing around but have not come up with a good plan on how to do this. I've setup a target using vblade, and accessed that from a separate system; however I'm unable to access it from the host, if I access it from 2 initiators at once then it seems to become corrupted of course.
Additionally, I am not sure what filesystem i can use which will allow what I want without becoming corrupted. I tried btrfs, xfs, zfs... I am thinking maybe I am going about it wrong, so thought I'd write this post and see if anyone can share some ideas. I think i need to use GFS but I haven't been able to get it setup correctly.
So my question is if it possible to access the same disk from two systems at the same time using AOE?
relevant stuff:
- I do not want to use nfs, samba, ssh, or any of these options.
- Security is not a concern it is on a closed internal air-gapped network.
- Yes I've searched but it is hard to find relevant info.
- the systems are each have 2 10gbe links, one for tcp/ip, one for ata over ethernet.
- I'm open to suggestions, but I don't especially want to have to code a new solution, and want to stick with open source software.
- I apologize in advance for my poorly written question.
