Subject: Waiters on OSD operations will hang if replies invalid?
Date: Thu, 07 Nov 2013 11:08:24 +0800 [thread overview]
Message-ID: <527B0428.7090306@ubuntukylin.com> (raw)
For ceph_sync_write()/ceph_osdc_readpages()/ceph_osdc_writepages(), the
user process or kernel thread will
wait for the pending OSD requests to complete on the corresponding
req->r_completion. But it seems they only are waked up in handle_reply()
and provided the replies are correct. What about if the replies are
invalid, as the situations of label 'bad_put' in this function intended
to capture, the waiters gotta hang there?
