Sync Cache drive with Array for most used file?

[iJumbo]

I have a question but i can't really find the answer, Cache drive is not "safe" as the array, but what about syncing a file from the array to the cache drive for faster reads but keeping it updated in the array at every write. Is that possible?

Not currently, you can use 2 or more devices and create a redundant cache pool.

Hmm that's expensive, even with the rsync command in a schedule or something like that?

That you can do.
