just to annotate the below a bit in case it's not clear... sorry - should have done that in the first email :-/ 10.8.30.244 is MGS and one MDS, 10.8.30.245 is the other MDS in the failover pair. 10.8.30.201 -> 208 are OSS's (one OST per OSS), and the fs is mounted in the usual failover way eg. mount -t lustre 10.8.30....@o2ib:10.8.30....@o2ib:/system /system from the below (and other similar logs) it kinda looks like the client fails and then renegotiates with all the servers. cheers, robin -- Dr Robin Humble, HPC Systems Analyst, NCI National Facility > Lustre: 13800:0:(o2iblnd_cb.c:459:kiblnd_rx_complete()) Rx from > 10.8.30....@o2ib failed: 5 > Lustre: 13799:0:(o2iblnd_cb.c:459:kiblnd_rx_complete()) Rx from > 10.8.30....@o2ib failed: 5 > Lustre: 615:0:(o2iblnd_cb.c:2384:kiblnd_reconnect()) 10.8.30....@o2ib: > retrying (version negotiation), 12, 11, queue_dep: 8, max_frag: 256, > msg_size: 4096 > Lustre: mgc10.8.30....@o2ib: Reactivating import > Lustre: 13797:0:(o2iblnd_cb.c:459:kiblnd_rx_complete()) Rx from > 10.8.30....@o2ib failed: 5 > Lustre: 13798:0:(o2iblnd_cb.c:459:kiblnd_rx_complete()) Rx from > 10.8.30....@o2ib failed: 5 > Lustre: 615:0:(o2iblnd_cb.c:2384:kiblnd_reconnect()) 10.8.30....@o2ib: > retrying (version negotiation), 12, 11, queue_dep: 8, max_frag: 256, > msg_size: 4096 > Lustre: Client system-client has started > Lustre: 13798:0:(o2iblnd_cb.c:459:kiblnd_rx_complete()) Rx from > 10.8.30....@o2ib failed: 5 > ... last message repeated 17 times ... > Lustre: 615:0:(o2iblnd_cb.c:2384:kiblnd_reconnect()) 10.8.30....@o2ib: > retrying (version negotiation), 12, 11, queue_dep: 8, max_frag: 256, > msg_size: 4096 > Lustre: 615:0:(o2iblnd_cb.c:2384:kiblnd_reconnect()) 10.8.30....@o2ib: > retrying (version negotiation), 12, 11, queue_dep: 8, max_frag: 256, > msg_size: 4096 > Lustre: 13798:0:(o2iblnd_cb.c:459:kiblnd_rx_complete()) Rx from > 10.8.30....@o2ib failed: 5 > Lustre: 615:0:(o2iblnd_cb.c:2384:kiblnd_reconnect()) 10.8.30....@o2ib: > retrying (version negotiation), 12, 11, queue_dep: 8, max_frag: 256, > msg_size: 4096 > Lustre: 615:0:(o2iblnd_cb.c:2384:kiblnd_reconnect()) 10.8.30....@o2ib: > retrying (version negotiation), 12, 11, queue_dep: 8, max_frag: 256, > msg_size: 4096 > Lustre: 13797:0:(o2iblnd_cb.c:459:kiblnd_rx_complete()) Rx from > 10.8.30....@o2ib failed: 5 > Lustre: 615:0:(o2iblnd_cb.c:2384:kiblnd_reconnect()) 10.8.30....@o2ib: > retrying (version negotiation), 12, 11, queue_dep: 8, max_frag: 256, > msg_size: 4096 > Lustre: 615:0:(o2iblnd_cb.c:2384:kiblnd_reconnect()) 10.8.30....@o2ib: > retrying (version negotiation), 12, 11, queue_dep: 8, max_frag: 256, > msg_size: 4096 > Lustre: 615:0:(o2iblnd_cb.c:2384:kiblnd_reconnect()) 10.8.30....@o2ib: > retrying (version negotiation), 12, 11, queue_dep: 8, max_frag: 256, > msg_size: 4096 > Lustre: 615:0:(o2iblnd_cb.c:2384:kiblnd_reconnect()) 10.8.30....@o2ib: > retrying (version negotiation), 12, 11, queue_dep: 8, max_frag: 256, > msg_size: 4096 > Lustre: 13800:0:(o2iblnd_cb.c:459:kiblnd_rx_complete()) Rx from > 10.8.30....@o2ib failed: 5 > >looks like it succeeds in the end, but only after a struggle. > >I don't have any problems with 1.8.1 <-> 1.8.1 or 1.6.7.2 <-> 1.6.7.2. > >servers are rhel5 x86_64 2.6.18-92.1.26.el5 1.6.7.2 + bz18793 (group >quota fix). >client is rhel5 x86_64 patched 2.6.18-128.1.16.el5-b_release_1_8_1 from >cvs 20090712131220 + bz18793 again. > >BTW, should I be using cvs tag v1_8_1_RC1 instead of b_release_1_8_1? >I'm confused about which is closest to the final 1.8.1 :-/ > >cheers, >robin >-- >Dr Robin Humble, HPC Systems Analyst, NCI National Facility >_______________________________________________ >Lustre-discuss mailing list >[email protected] >http://lists.lustre.org/mailman/listinfo/lustre-discuss _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
