Thanks, I have already tried "UFSSUSPEND/UFSRESUME ioctls on the /dev/ufssuspend", and I found it actually not work. In Linux, if I send freeze ioctl, all write operations will be blocked unless I send thaw ioctl. While for "UFSSUSPEND/UFSRESUME ioctls", it does not work in that way. that is: If I send UFSSUSPEND ioctl, I still can do write operations, like create files, etc. I am still looking that the code of ufssuspend, and if that really not works, i may implement that in my driver level. thanks for any advice. -- View this message in context: http://freebsd.1045724.n5.nabble.com/About-Filesystem-freeze-thaw-in-freebsd-tp5989205p5992079.html Sent from the freebsd-fs mailing list archive at Nabble.com.
