Dear all, I want to set max_pages_per_rpc to 64 instead of 256 lustre mgs/mdt version 2.53 lustre oss version 2.53 lustre client 2.6
on client I have done: lctl get_param osc.hiskp3-OST*.max_pages_per_rpc osc.hiskp3-OST0001-osc-ffff88105dba4800.max_pages_per_rpc=256 osc.hiskp3-OST0002-osc-ffff88105dba4800.max_pages_per_rpc=256 osc.hiskp3-OST0003-osc-ffff88105dba4800.max_pages_per_rpc=256 osc.hiskp3-OST0004-osc-ffff88105dba4800.max_pages_per_rpc=256 lctl set_param osc.hiskp3-OST*.max_pages_per_rpc=64 this works, but after remount I get again 256 therefore I want to make it permant with lctl conf_param hiskp3-OST*.osc.max_pages_per_rpc=64 But I get the message, that this command have to be given on mdt unfortunately I go to our combined mgs/mdt and get Lustre: Setting parameter hiskp3-OST0000-osc.osc.max_pages_per_rpc in log hiskp3-client LustreError: 956:0:(obd_config.c:1221:class_process_config()) no device for: hiskp3-OST0000-osc-MDT0000 LustreError: 956:0:(obd_config.c:1591:class_config_llog_handler()) MGC192.168.128.200@o2ib: cfg command failed: rc = -22 Lustre: cmd=cf00f 0:hiskp3-OST0000-osc-MDT0000 1:osc.max_pages_per_rpc=64 than I can not mount client and want to go back lctl set_param osc.hiskp3-OST*.max_pages_per_rpc=64 Lustre: Modifying parameter hiskp3-OST0000-osc.osc.max_pages_per_rpc in log hiskp3-client Lustre: Skipped 1 previous similar message LustreError: 966:0:(obd_config.c:1221:class_process_config()) no device for: hiskp3-OST0000-osc-MDT0000 LustreError: 966:0:(obd_config.c:1591:class_config_llog_handler()) MGC192.168.128.200@o2ib: cfg command failed: rc = -22 Lustre: cmd=cf00f 0:hiskp3-OST0000-osc-MDT0000 1:osc.max_pages_per_rpc=256 obviously what I have done was completly wrong and I can no longer mount a client, mounted clients are working. How can I get it back working? hiskp3-MDT0000 ist the label of the mgs/mdt but hiskp3-OST0000-osc-MDT0000 seems to be incorrect What I have to do to get the mgs/mdt working again? Its your production cluster Any help is welcome Best Harald _______________________________________________ lustre-discuss mailing list lustre-discuss@lists.lustre.org http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
