Hi, Sorry for the late reply. So I summarized that NFS with DRDB is enough for POC purpose but not recommended for large scale production, where ceph would be more suitable.
Thanks for the insight for this problem. -- Regards, William On 09-Nov-17 19:28:49, Ivan Kudryavtsev <[email protected]> wrote: Hi. I wouldn't recommend go with HA NFS, because you have to use it in sync mode which leads to poor performance. I suggest using ceph with ssd (or even optane for log devices), because it's the thing which is supposed to be clustered and kvm "knows" how to use it properly and handle node outages via librados. But, still, nfs sync over drbd and keepalived should work, but not a scalable solution, of course. 9 нояб. 2017 г. 19:10 пользователь "Makrand" написал: > Hi William, > > The HA capabilities for storage are offered by OS/Vendor you're using for > storage.
