From the docs, i understand NFS is not recommended, because NFS is slow.
"This style of high availability differs from data replication in that it requires a shared file system which is accessible by both the live and backup nodes. Typically this will be some kind of high performance Storage Area Network (SAN). We do not recommend you use Network Attached Storage (NAS), e.g. NFS mounts to store any shared journal (NFS is slow)."
1. Is this an issue with the latest version of NFS too.
2. In some threads, they have mentioned GFS with ext4. What other filesystems options we can consider. Please let me know.
Thanks in advance.
