    Write-Back cache!

    Hi, We are looking to use NVMe SSD as write-back cache just to enhance write IOPS while reads should only be served by backend storage based on HDDs. Is this possible with FreeBSD ? Regards.

    Invalidate file in cache (flush file cache) on FreeBSD ?

    I want to invalidate file and remove it from Cache, so that any additional access to that file will go through the lower level storage device. In linux, it's done using syscall ioctl(file_desc, BLKFLSBUF) but what is the equivalent in freeBSD ? P.S. I related the generate file cache...
