Hi,
We are trying to make a lab with ACS 4.16 and Linstor. As soon as we
finish the tests we can give you some approach for the results. Are
someone already try this technology?.
Regards,

Since NFS alone doesn't offer HA. What do you recommend for HA NFS?

I have similar consideration when start exploring Cloudstack , but in
reality Clustered Filesystem is not easy to maintain. You seems have
choice of OCFS or GFS2 , gfs2 is hard to maintain and in redhat , ocfs
recently only maintained in oracle linux. I believe you do not want to
choose solution that is very propriety . Thus just SAN or ISCSI o is not
really a direct solution here , except you want to encapsulate it in NFS
and facing Cloudstack Storage.
It work good on CEPH and NFS , but performance wise, NFS is better . And
all documentation and features you saw in Cloudstack , it work perfectly
on NFS.
If you choose CEPH, may be you have to compensate with some performance
degradation,

I've been using Ceph in prod for volumes for some time. Note that
although
I had several cloudstack installations, this one runs on top of Cinder,
but it basic translates as libvirt and rados.
It is totally stable and performance IMHO is enough for virtualized
services.
IO might suffer some penalization due the data replication inside Ceph.
Elasticsearch for instance, the degradation would be a bit worse as there
is replication also in the application size, but IMHO, unless you need
extreme low latency it would be ok.
Best,
Leandro.

Hello community,
today I need your experience and knowhow about clustered/shared
filesystems based on SAN storage to be used with KVM.
We need to consider about a clustered/shared filesystem based on SAN
storage (no NFS or iSCSI), but do not have any knowhow or experience
with
this.
Those I would like to ask if there any productive used environments out
there based on SAN storage on KVM?
If so, which clustered/shared filesystem you are using and how is your
experience with that (stability, reliability, maintainability,
performance,
useability,...)?
Furthermore, if you had already to consider in the past between SAN
storage or CEPH, I would also like to participate on your
considerations
and results :)
Regards,
Michael
