Redundant NFS Storage for ACS
Hi,
We are new to Apache CloudStack. We are looking for a Primary Storage (NFS
share) solution, where it does not fail because of single node failure. Is
there a way where I can use the NFS via any kind of clustering, so that
when one node fails i will still have the VM's working from another node
which is in ACS using the NFS cluster.
Has anyone done the Ceph Storage as NFS (NFS Ganesha) and used it for the
ACS on CentOS 7. Please share the steps so that we can look into it.
Basically we need a system that has:-
1. One single point IP address with the shared mount point being same.
2. NFS storage, as Apache CloudStack supports HA only with NFS.
3. I need to deploy around around 60 VM's for our application.
If NFS storage having the VM's goes down and not able to get back. How to
fix this, so that we can get back the VM's in running state.
Regards,
Mark.

This scheme can trigger HA
If you can, please provide remote login information. I can check it for you.

Hi Jerry,
I have tried doing the same as you mentioned but still no luck. HA doesn't work, host stucks in alert state.
*Primary Storage 1 -* Ceph RBD, *Tag= *rbd *Primary Storage 2 - *NFS (Size=100 MB) All Offerings created with storage tag= rbd
In my case, HA works only when NFS as primary.
Do I need to do anything else to make the hosts to write all heartbeat times to the KVMHA directory under NFS. (have no Idea about this) Any specific steps to make it work.
And What if Primary NFS server holding heartbeat fails? Will it work with another Primary NFS storage?
Regards,
Mark.

Hi All,
Can some one suggest for the NFS Primary Storage for ACS, that does not
goes off due to NFS host failure in CentOS 7.6
Regards,
Mark.

Hi Mark
I can provide one of my solutions for your reference:
Hypervisor = KVM
CloudStack = 4.11.3
Primary Storage0 = Ceph RBD, tag = rbd
Primary Storage1 = NFS
Primary Storage0 stores VM Volume,
Primary Storage1 stores the heartbeat of KVM (suggested capacity is 100MB)
all Compute Offerings.Storage Tags and Disk Offerings.Storage Tags = "rbd"
ALL Host tag = ha
Global setting-> ha.tag = ha
With the above configuration, all hosts in the cluster are connected to two storages (RBD, NFS) at the same time; all heartbeat times are written to the KVMHA directory under NFS;
When the host fails, it detects the KVM heartbeat timestamp through Primary Storage1 and triggers VM HA

You have to deploy HA NFS outside Cloudstack. CS doesn't care about storage
fault tolerance.
Gluster is fine (shared mountpoint), Ceph is fine too, HA Nfs can be
deployed with certain approaches or with proprietary appliances.
