replay-single test_73c: MDS returns error when no objects available

Bug Major Resolved Cannot Reproduce WC Triage Maloo Fri, 4 Oct 2013 14:07:01 +0000 Thu, 9 Jan 2020 07:22:04 +0000 Thu, 9 Jan 2020 07:22:04 +0000 Lustre 2.5.0 0 2 <p>It looks like the MDS timed out trying to create any objects on the OSTs (which are very slow due to ZFS on a single VM disk), and returned an error back to multiop doing open(O_CREATE|O_RDWR). The MDS shouldn't ever return an error during create when all of the OSTs are out of objects. Instead, the MDS should try indefinitely to create the OST objects, and it can return -EINPROGRESS (instead of the current -EIO) to the client so that it will retry without blocking up an MDS thread.</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>15:14:44:Lustre: DEBUG MARKER: == replay-single test 73c: open(O_CREAT), unlink, replay, reconnect at last_replay, close == 15:13:31 (1380838411) 15:14:44:Lustre: lustre-OST0006-osc-MDT0000: slow creates, last=[0x0:0x1:0x0], next=[0x0:0x1:0x0], reserved=0, syn_changes=1, syn_rpc_in_progress=8, status=0 15:14:44:Lustre: lustre-OST0000-osc-MDT0000: slow creates, last=[0x0:0x1:0x0], next=[0x0:0x1:0x0], reserved=0, syn_changes=0, syn_rpc_in_progress=17, status=0 15:14:44:Lustre: lustre-OST0001-osc-MDT0000: slow creates, last=[0x0:0x1:0x0], next=[0x0:0x1:0x0], reserved=0, syn_changes=17, syn_rpc_in_progress=8, status=0 15:14:44:LNet: Service thread pid 3621 completed after 60.00s.
