aufs does not use aio. It's only the coss driver which uses aio.
BTW I believe pthreads are not so good on FreeBSD at all and work different as
on Linux
It is rumored pthreads on FreeBSD 5 should work fine for aufs, but I have
not verified this.
aufs requires a pthreads implementation using kernel threads, allowing
multiple threads to be waiting for disk I/O to complete. It does not work
with user level threads where the whole process gets blocked if one thread
is blocked by disk I/O.
strange also, remembering on FreeBSD without posix-aio loaded, that even
if
configure --enable-storeio=diskd,aufs,null --with-aio
gives an error but completes and make goes through, I never tried to run it
then
Which error is seen?
