Dear All, I am trying to make two different file system, in an simple environment, with two MDS (in failover) and two OSS (in failover). But i get an error when i try to mount the second filesystem.
My first step was created the mgs in my first MDS node: [root@CASSACA-MDS-01 ~] mkfs.lustre --reformat --mgs \ --servicenode=10.10.0.19@o2ib \ --servicenode=10.10.0.20@o2ib \ /dev/vg_mgs/lv_mgs Then, I created the two different MDT (all in the same node): [root@CASSACA-MDS-01 ~] mkfs.lustre --reformat --mdt\ --fsname=chivoacc \ --index=0 \ --mgsnode=10.10.0.19@o2ib \ --mgsnode=10.10.0.20@o2ib \ --failnode=10.10.0.20@o2ib \ /dev/vg_mdtmgt_01/lv_mdtmgt_01 Finally I mounted the the mgs and the two mdt without any problem. [root@CASSACA-MDS-01 ~] mkfs.lustre --reformat --mdt\ --fsname=chivodp \ --index=1 \ --mgsnode=10.10.0.19@o2ib \ --mgsnode=10.10.0.20@o2ib \ --failnode=10.10.0.20@o2ib \ /dev/vg_mdtmgt_02/lv_mdtmgt_02 My second step was created the 3 ost for the fsname=chivoacc and 6 ost for the fsname=chivodp in my first OSS: [root@CASSACA-OSS-01 ~]# mkfs.lustre --ost --index=0 --fsname=chivoacc --reformat --failnode=10.10.0.22@o2ib --mgsnode=10.10.0.19@o2ib --mgsnode=10.10.0.20@o2ib /dev/ost000vgchivoacc/ost0000vchivoacc (the same for the other two ost) [root@CASSACA-OSS-01 ~]#mkfs.lustre --ost --index=0 --fsname=chivodp --reformat --failnode=10.10.0.22@o2ib --mgsnode=10.10.0.19@o2ib --mgsnode=10.10.0.20@o2ib /dev/ost000vgchivodp/ost0000vchivodp (the same for the other five ost) Finally, I mounted the three ost for the fsname=chivoacc and the six ost for the fsname=chivodp without any problem. My third step was mounted the fsname chivoacc in a client without any problem, but, when a try to mount the fsname chivodp in a client, i get this error: [root@CASSACA-cl-01 ~] mount -t lustre 10.10.0.19@o2ib:10.10.0.20@o2ib:/chivodp /mnt/new_archive mount.lustre: mount 10.10.0.19@o2ib:10.10.0.20@o2ib:/chivodp at /mnt/new_archive failed: Invalid argument This may have multiple causes. Is 'chivodp' the correct filesystem name? Are the mount options correct? Check the syslog for more info. I get this from the kernel log: [1382151.599809] Lustre: Mounted chivoacc-client [1382192.901603] Lustre: Unmounted chivoacc-client [1382201.442196] LustreError: 2324:0:(lmv_obd.c:525:lmv_check_connect()) chivodp-clilmv-ffff97659ab28000: no target configured for index 0.
