Hello, I am trying to install lustre from rpm and here is the errors i recived, please tell me what i am doing wrong ( i only had problems with starting mds ) the setup is 2 boxes n1 and n2, n1 runs mds and oss, n2 runs oss only the rpms on both boxes are: kernel-smp-2.6.9-22.EL_lustre.1.4.5.1.i686.rpm lustre-1.4.5.1-2.6.9_22.EL_lustre.1.4.5.1smp.i686.rpm lustre-modules-1.4.5.1-2.6.9_22.EL_lustre.1.4.5.1smp.i686.rpm the config was generated using lwizard. ( the fs in the config was ext3 but i manualy changed it to ldiskfs ) i did this on both boxes: lconf --reformat /etc/lustre/config.xml n2 had no problems but on n1 i gor the errors: ..... loading module: mds srcdir None devdir mds NETWORK: NET_st-node-1a.xxxxx.xxxxxxxxxxx.com_tcp .xxxxx.xxxxxxxxxxx.com_tcp_UUID tcp st-node-1a.xxxxx.xxxxxxxxxxx.com 988 OSD: ost1 ost1_UUID obdfilter /dev/sda6 0 ldiskfs no 0 0 OST mount options: errors=remount-ro MDSDEV: mds1 mds1_UUID /mds1 ldiskfs no recording clients for filesystem: FS_fsname_UUID Recording log mds1 on mds1 LOV: lov_mds1 240b9_lov_mds1_d683a04db2 mds1_UUID 0 65536 0 0 [u''ost1_UUID'', u''ost2_UUID''] mds1 OSC: OSC_st-node-1a.xxxxx.xxxxxxxxxxx.com_ost1_mds1 240b9_lov_mds1_d683a04db2 OSC: OSC_st-node-1a.xxxxx.xxxxxxxxxxx.com_ost2_mds1 240b9_lov_mds1_d683a04db2 End recording log mds1-clean on mds1 MDSDEV: mds1 mds1_UUID /mds1 ldiskfs 5000000 no MDS mount options: errors=remount-ro ! /usr/sbin/lctl (22): error: setup: Invalid argument and in /var/log/messages: Jan 29 10:58:46 st-node-1a kernel: LustreError: 4415:0:(ldlm_lib.c:233:client_obd_setup()) target UUID must be less than 38 characters Jan 29 10:58:46 st-node-1a kernel: LustreError: mds1: the profile mds1 could not be read. If you recently installed a new version of Lustre, you may need to re-run ''lconf --write_conf <yourconfig>.xml'' command line before restarting the MDS. Jan 29 10:58:46 st-node-1a kernel: LustreError: 4420:0:(obd_config.c:304:class_cleanup()) Device 3 not setup So the first question is what is wrong here... then i thought (based on this error target UUID must be less than 38 characters) that the hostnames i used were too long so added short names in /etc/hosts regenerated the config and tried again but i got "No hosts found", i alos tried to go back from ldiskfs to ext3 but even though the config was new in the logs i still saw ldiskfs (it''s like the config was cached). The second question is how do i clean the sistem so i can use a totaly different config ( i tried --cleanup and i tried uninstalling the rpms but that didnt help. ) there is also a small problem when trying to start using /etc/init.d/lustre script on both nodes: ! /usr/sbin/lctl (13): error: setup: Permission denied Thank you -- Best regards, Ruslan mailto:ruslan.talpa@gmail.com
