Hello. I'm new to Lustre. I'm writing because I have changed some IP's and I can't get everything mounted.
4 total servers (changed IPs of just OSS servers) head - MGT/MGS (no IP change) oss0 - OSS (changed IP) oss1 - OSS (changed IP) oss2 - OSS (changed IP) brianjm was helpful in IRC and hinted I needed to read the manual about Changing a NID. I followed this procedure : 4.3.12 Changing a Server NID On all servers, I made sure everything was unmounted: umount /mnt/mdt and umount /mnt/lustre On head, I ran : tunefs.lustre --writeconf /dev/sdb1 On oss0, I ran : tunefs.lustre --writeconf /dev/sda5 On oss1, I ran : tunefs.lustre --writeconf /dev/sda5 On oss2, I ran : tunefs.lustre --writeconf /dev/sda5 I then mounted everything. First the mdt on server head On head: mount /mnt/mdt -- this didn't throw any errors. checked the logs and no errors. On oss0: mount /mnt/lustre mount.lustre: mount jupi...@tcp0:/mylustre at /mnt/lustre failed: No medium found This filesystem needs at least 1 OST Error log on oss0: Jan 11 14:12:25 compute-oss-0-0 kernel: LustreError: 151-5: There are no OST's in this filesystem. There must be at least one active OST for a client to start. Jan 11 14:12:25 compute-oss-0-0 kernel: LustreError: 4136:0:(ldlm_request.c:986:ldlm_cli_cancel_req()) Got rc -108 from cancel RPC: canceling anyway Jan 11 14:12:25 compute-oss-0-0 kernel: LustreError: 4136:0:(ldlm_request.c:1575:ldlm_cli_cancel_list()) ldlm_cli_cancel_list: -108 Jan 11 14:12:25 compute-oss-0-0 kernel: LustreError: 4136:0:(obd_mount.c:1951:lustre_fill_super()) Unable to mount (-123) The same error appears on the other oss servers. Any help would be greatly appreciated. -Brendon _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
