it is a wrong assumption. these are kernel processes - they are created and killed by the kernel.

can you show output of df and mount commands?

as for me it seems ok. if you're sure, you can try umount -f /oracle.

The immortal process are 8,they never die

Please issue lsof +D /oracle and show the output in code tags, thanks.

And do not try to kill those aioservers. Once started they will stay active, even if not needed. They have a starting amount and a max amount. If the system needs more of them than the starting amount, it spawns new ones until max is reached but, as said, they stay in the process list and do not terminate. If not needed, they just idle and do not really eat performance.

if you want to see them dead, try to change some parameters in the system ;-)

Code:
$ ioo -L | grep posix_aio
posix_aio_active          0             0                    boolean           S
posix_aio_maxreqs         128K   128K   128K   4K     1M     numeric           D
posix_aio_maxservers      30     30     30     1      20000  numeric           D
posix_aio_minservers      3      3      3      0      20000  numeric           D
posix_aio_server_inactivity

Already play with ioo,i set for test 1 to posix_aio_server_inactivity
and
aio_server_inactivity
But nothing change
