Hi all, I''m using lustre 1.8.0 on CentOS 5.0. I have a problem when MDS is restarted (forced). After, I mount lustre on MDS, the following are logs on MDS: Sep 26 01:43:09 MDS2 kernel: LustreError: 14452:0:(mds_open.c:432:mds_create_objects()) error creating objects for inode 20945086: rc = -5 Sep 26 01:43:09 MDS2 kernel: LustreError: 14455:0:(mds_open.c:432:mds_create_objects()) error creating objects for inode 20945086: rc = -5 Sep 26 01:43:10 MDS2 kernel: LustreError: 14441:0:(mds_open.c:432:mds_create_objects()) error creating objects for inode 20945086: rc = -5 Sep 26 01:43:10 MDS2 kernel: LustreError: 14456:0:(mds_open.c:432:mds_create_objects()) error creating objects for inode 20945086: rc = -5 .... Check df -h on clients, it''s OK. But client can''t read or write data to disk (storage lustre). mdt and mds on the same node, that is MDS. What''s happen with my system, and how to fix it??? Help me, please! Thanks, -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.lustre.org/pipermail/lustre-discuss/attachments/20090926/3f94d3d1/attachment.html

Are the OSTs mounted and accessible? Cheers, Andreas -- Andreas Dilger Sr. Staff Engineer, Lustre Group Sun Microsystems of Canada, Inc.
