Well e2fsck didn't help. Same error for those two (Function not implemented). I also see in the MGS/MDS log each time I try: LustreError: 5974:0:(mgs_handler.c:487:mgs_handle_target_reg()) Failed to write nscratch-OST0001 log (-38) LustreError: 5973:0:(mgs_handler.c:487:mgs_handle_target_reg()) Failed to write nscratch-OST0002 log (-38)

I just did it again to test. Followed the instructions in section 4.3.11 in the luster manual. Mounting MDT goes fine. Mounting the OSTs, the first just seems to be hanging. The other two both gave: [r...@ost2 ~]# mount -t lustre /dev/VG_lustre/scratch_ost2 /mnt/lustre/scratch/ost2/ mount.lustre: mount /dev/VG_lustre/scratch_ost2 at /mnt/lustre/scratch/ost2 failed: Function not implemented Currently running e2fsck on the two OSTs that didn't want to mount. I have already run it, but doing so again, just in case.

You can binary edit this flag in the "CONFIGS/mountdata" file on each OST. Alternately, you could follow the process in the manual, and run writeconf on the MGS and MDS as well, and then the OSTs should be able to register again. > I see in syslog: > LustreError: 6182:0:(obd_mount.c:1097:server_start_targets()) Required registration failed for nscratch-OST0001: -38 Cheers, Andreas -- Andreas Dilger Lustre Technical Lead Oracle Corporation Canada Inc. _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
