PR 2407141: You cannot provision virtual disks to be shared in multi-writer mode as eager zeroed thick-provisioned by using the vSphere ClientĪ shared virtual disk on a vSAN datastore for use in multi-writer mode, such as for Oracle RAC, must be eager zeroed thick-provisioned. The text relevant to Oracle RAC cluster is shown as below.
#No more rack app Patch
This patch resolves this issue and now one can use thin provisioned vmdk’s with multi-writer attribute for Oracle RAC cluster starting VMware vSAN 6.7 P01 (ESXi 6.7 Patch Release ESXi670-201912001). The current limitation is Oracle RAC shared vmdk’s need to be Eager Zero Thick for the multi-writer attribute to be enabled for the clustering software to work. VMware vSAN 6.7 P01 (ESXi 6.7 Patch Release ESXi670-201912001) release date, addresses a key limitation when provisioning shared disks with multi-writer for Oracle RAC cluster. In vSAN, the Eager Zero thick attribute can be controlled by a rule in the VM Storage Policy called ‘Object Space Reservation’ which need to be set to 100% which pre-allocates all object’s components on disk.
#No more rack app how to
KB 2121181 provides more details on how to set the multi-writer option to allow VM’s to share vmdk’s on VMware vSAN. Oracle RAC on VMware vSAN prior vSAN 6.7 P01 (ESXi 6.7 Patch Release ESXi670-201912001) So, in order for all of the VM’s to access the shared vmdk’s simultaneously, the multi-writer protection needs to be disabled. vmdk files ie all VM’s have exclusive access to their vmdk files. This applies to other clustered applications as well running on vSAN which uses multi-writer disks for clustering purposes e.g Oracle RAC, Redhat Clustering, Veritas Infoscale etcīy default, in a VM, the simultaneous multi-writer “protection” is enabled for all.
