Hi Eric, it seems that I'm hitting the same deadlock, but I don't use dual primary, and the split brain never occurs. Can you post your drbd config as long with the infiniband hba model and version you're using? regards, -- matteo ----- Messaggio originale ----- > Da: "Eric Blevins" <ericlb100 at gmail.com> > A: drbd-user at lists.linbit.com > Inviato: Giovedì, 15 gennaio 2015 17:53:48 > Oggetto: [DRBD-user] Possible IPoIB deadlock with DRBD > > We are using Proxmox with DRBD in dual primary using IPoIB for > transport > Recently tested Proxmox upcoming 3.10 kernel based on the kernel from > RHEL 7 and started having problems with DRBD. > > The kernel came with DRBD 8.4.3, I have also compiled and installed > 8.4.5 and both experience the same problem. > > During times of heavy IO loads (backups) DRBD will timeout and split > brain, I have included some logs below. > I stumbled on a couple LKML threads that discusses a deadlock with > IPoIB and IO that happens over the IPoIB such as iSCSI or NFS. > https://lkml.org/lkml/2014/2/21/655 > http://lkml.org/lkml/2014/4/24/543 > > Is it likely that DRBD could also trigger the deadlock discussed on > LKML? > If not, do you have any other suggestions on how I can prevent this > timeout? > > > Node A: > Jan 5 03:23:51 vm6 kernel: [2221944.335766] drbd drbd0: peer( > Primary > -> Unknown ) conn( Connected -> Timeout ) pdsk( UpToDate -> DUnknown > ) > Jan 5 03:23:51 vm6 kernel: [2221944.335782] drbd drbd0: asender > terminated > Jan 5 03:23:51 vm6 kernel: [2221944.335784] drbd drbd0: Terminating > drbd_a_drbd0 > Jan 5 03:23:51 vm6 kernel: [2221944.335846] block drbd0: new current > UUID > BD9DB97EC672F5C9:8F2DD469C771058B:925C07CF6316212D:925B07CF6316212D > Jan 5 03:23:51 vm6 kernel: [2221944.347788] drbd drbd0: Connection > closed > Jan 5 03:23:51 vm6 kernel: [2221944.347834] drbd drbd0: conn( > Timeout > -> Unconnected ) > Jan 5 03:23:51 vm6 kernel: [2221944.347836] drbd drbd0: receiver > terminated > > > Node B: > Jan 5 03:23:51 vm5 kernel: [2223090.170391] drbd drbd0: sock was > shut > down by peer > Jan 5 03:23:51 vm5 kernel: [2223090.170409] drbd drbd0: peer( > Primary > -> Unknown ) conn( Connected -> BrokenPipe ) pdsk( UpToDate -> > DUnknown ) > Jan 5 03:23:51 vm5 kernel: [2223090.170412] drbd drbd0: short read > (expected size 16) > Jan 5 03:23:51 vm5 kernel: [2223090.170421] drbd drbd0: asender > terminated > Jan 5 03:23:51 vm5 kernel: [2223090.170423] drbd drbd0: Terminating > drbd_a_drbd0 > Jan 5 03:23:51 vm5 kernel: [2223090.170480] block drbd0: new current > UUID > 2628F73F9DAE5EDF:8F2DD469C771058B:925C07CF6316212D:925B07CF6316212D > Jan 5 03:23:51 vm5 kernel: [2223090.185536] drbd drbd0: Connection > closed > Jan 5 03:23:51 vm5 kernel: [2223090.185585] drbd drbd0: conn( > BrokenPipe -> Unconnected ) > Jan 5 03:23:51 vm5 kernel: [2223090.185587] drbd drbd0: receiver > terminated > > Eric > _______________________________________________ > drbd-user mailing list > drbd-user at lists.linbit.com > http://lists.linbit.com/mailman/listinfo/drbd-user > > > -- > This message has been scanned for viruses and dangerous content by > RMnet MailScanner, and is believed to be clean. > > Click here to report this message as spam. > http://efa1.rmnet.it/cgi-bin/learn-msg.cgi?id=4C1D868B16.A88D5&token=94b3a0f1dfd9db46184ad15228603c27 > >
