Assume starting one disk write action, the vdev_disk_io_start will be called
from zio_execute.
static int vdev_disk_io_start(zio_t *zio)
{
..
bp->b_lblkno = lbtodb(zio->io_offset);
..
}
After scaning over the zfs source, I find the zio->io_offset is only set value
in
would it possible to use ZFS snapshot as way
to doing hot backup for oracle database?
anybody have tried that?
Thanks.
Jason
