Good morning All,
I have two storage servers, and would love to mirror them live, instead of rsync.
Currently I have Server A and Server B.
Server A:
Server B:
My plan is to install Ubuntu Server w/ZoL on each. Server A being configured in a gigantic effective raid 10, and Server B being configured as RAIDz2.
That should give me roughly 18TB on Server A, and roughly 16TB on Server B. (capacity taken using the Serve The Home raid calc, rounded down)
I don't need more than around 13TB of space right now, and I'm not intending on expanding anytime soon.
I currently use Server A as Storage for a XenServer Hypervisor over NFS.
I know what there are a lot of backup methods for me to use from Server A to Server B, especially while both running Ubuntu Server and ZFS.
Reading through the GlusterFS website, it looks to be pretty solid for live mirroring the two servers. Given the substantial difference in performance between the two systems, is GlusterFS a good choice? Is there another method for mirroring both servers live?
If needed, I don't mind setting up rsync to run every hour or so, but I'd much rather go with live replication if possible.
I am not intending on using the installed SSDs for anything beyond OS drives. Would there be a substantial performance difference if I used additional SSDs for either ZFS or GlusterFS?
Also! Please don't hold back regarding reality checks. The above is a combination of sleep deprivation and shower thoughts.
