What release are you working on? Have you seen the latest code in
master that allows client operations to preempt scrub?
bool PG::write_blocked_by_scrub(const hobject_t& soid)
{
if (soid < scrubber.start || soid >= scrubber.end) {
return false;
}
if (scrub_can_preempt) {
if (!scrub_preempted) {
dout(10) << __func__ << " " << soid << " preempted" << dendl;
scrub_preempted = true;
} else {
dout(10) << __func__ << " " << soid << " already preempted" << dendl;
}
return false;
}
return true;
}

Hi~
We have make some modifications to osd queue so that Scrub would stay
in queue when client_op is busy. But this brings a problem, some write
request would be blocked by the scrub in queue too long time. So we
want to block a write request only when the scrub out of queue. The
question is, is there any accident will happen to it?
