Setting up drive pooling on fresh OMV5 install, picking between "mergerfs folders" or "Union Filesystems" plugins. Can either of these always write to a specific drive(/folder) unless that drive(/folder) is full?
Looking for something like write caching - focus my writes on an SSD that's part of the drive pool, run a script to move it off cache regularly. Didn't see anything that looked like this in "Create policy" for either plugin - perhaps there's some configurable way to do this in the underlying (FUSE?) filesystem?
Alternatively - is SSD write caching available in OMV, and I'm a doofus who couldn't find it?
Thanks in advance!
