NFS single server cluster creation needs several configuration changes

[fwiw6430]

After cluster creation using the stuck whose OCID is as follows,
ocid1.ormstack.oc1.eu-frankfurt-1.aaaaaaaay3sn4cgukqp2f5cbyimu6eq2x2pwzh5bxgdj3ngcxj2owgff6yba

I needed to apply following changes on NFS server to complete setting up NFS service.

1. Change /etc/fstab by both correcting mount point and eliminating nobarrier option
   #/dev/vg_nfs_disk/disk /mnt/nfsshare xfs defaults,_netdev,nofail,noatime,inode64,nobarrier,uquota,prjquota 0 2
   /dev/vg_nfs_disk/disk /mnt/nfsshare/exports xfs defaults,_netdev,nofail,noatime,inode64,uquota,prjquota 0 2
2. Change /etc/exports by modifying CIDR range (This file seems not to support classless CIDR, like /22)
   #/mnt/nfsshare/exports 10.0.8.0/255.255.252.0(rw,sync,no_root_squash,no_all_squash,no_subtree_check,insecure_locks) 10.0.4.0/255.255.252.0(rw,sync,no_root_squash,no_all_squash,no_subtree_check,insecure_locks)
   /mnt/nfsshare/exports 10.0.0.0/255.255.0.0(rw,sync,no_root_squash,no_all_squash,no_subtree_check,insecure_locks)

The issues I reported in my previous post came down to the fact that this stuck configuration could not handle scratch filesystem configuration with DenseIO shape.
To fix this, line 11 in locals.tf under the stuck top directory can be modified like this;
# standard_storage_node_dual_nics = (length(regexall("^BM", local.derived_storage_server_shape)) > 0 ? (length(regexall("Standard",local.derived_storage_server_shape)) > 0 ? true : false) : false)
standard_storage_node_dual_nics = (length(regexall("^BM", local.derived_storage_server_shape)) > 0 ? (length(regexall("Standard",local.derived_storage_server_shape)) > 0 ? true : (length(regexall("DenseIO",local.derived_storage_server_shape)) > 0 ? true : false)) : false)
