How I can I quiesce / freeze all writes to zfs and zpool if want to take
hardware level snapshots or array snapshot of all devices under a pool ?
are there any commands or ioctls or apis available ?
zpool export <pool>
zpool import <pool>
That is the only documented and supported way to do it that I'm aware
of, and yes that does take the pool off line but that way you can be
sure it isn't changing.
The only other way I know of to freeze a pool is for testing purposes
only and if you want to learn about that you need to read the code
because I'm not going to disclose it here in case it is miss used.
