Protection Domains and Domain Marks

Question

Can someone explain please

1) What _exactly_ is a domain mark?

2) Why does it accelerate failover and notably failback?

3) Do you need to regenerate / run a DomainMark job each time?

4) When SyncIQ is used to transfer a SmartLock directory, what is the expected domain mark that will be set? A synciq domain mark, a worm domain mark, or both? This last question might be a lot about inner workings, but essentially closes the circle and brings me back to question number 1: what is a domain mark?

Thanks

Hello jammac,

A domain mark is a mark on files and directories that are part of protection domains that prevents modifications.
It can accelerate as it has to mark every file and directories.
It is recommended to run the Domain Mark job ahead before failing over or back to make the it faster.
In most cases it is worm as it is preventing modifications to files and directories.

Here is also a link to the web administrator guide. https://dl.dell.com/content/manual63960936-powerscale-onefs-9-2-1-0-web-administration-guide.pdf
