Casper, thanks for the tip! Actually I'm not sure if this would work
for me. I wanted to use directio to bypass the file system cache when
reading/writing files. That's why I chose UFS instead of ZFS. Now if I
create UFS on top of zvol, I'm not sure if a call to directio() would
actually do its work...
Why not just use ZFS and set the similar options on the ZFS dataset:
zfs set primarycache=metadata <datasetname>
That is a close approximation to the UFS feature of directio() for
bypassing storing the data in the filesystem cache.
