OneFS 8.2.2 introduces a feature for large file support, permitting the maximum allowable file size in a PowerScale cluster to increase four-fold, from 4 tebibytes previously, to 16 tebibytes. For more information about the large file support feature for 16 TiB, see the Dell PowerScale OneFS Best Practices white paper.
Important: It is critical to note the implications of this feature, because after it is enabled, it cannot be disabled.
If large file support is enabled for 16 TiB on a source cluster, all SyncIQ policies only connect with target clusters that also have large file support enabled, as illustrated in Figure 43. Otherwise, SyncIQ policies fail when establishing a connection with a cluster without large file support.
These unique requirements apply to new and existing SyncIQ policies. Furthermore, workflow impacts for existing SyncIQ policies are possible, if for any reason the target cluster does not have resources for the 16 TiB feature.
