Hello list, I've migrated our mdt data to a new machine via tar and getfattr, and then did the following:
mds/mgs: rm OBJECTS/* CATALOGS mds/mgs: tunefs.lustre --writeconf --mgs --mdt --fsname=lustre --erase-param --param mdt.quota_type=ug2 --param mdt.group_upcall=/usr/sbin/l_getgroups --param failover.node=172.17.4.124@o2ib /dev/sdb mds/mgs: mount -t lustre /dev/sdb /mdt Everything seems OK up to this point. I then modified each ost with: oss: tunefs.lustre --writeconf --erase-param --param mgsnode=172.17.4.123@o2ib:172.17.4.124@o2ib --param ost.quota_type=ug2 /dev/sdb Then, when I try to mount the ost I get in dmesg: Lustre: 3269:0:(client.c:1476:ptlrpc_expire_one_request()) @@@ Request x1361639653769217 sent from MGC172.17.4.123@o2ib to NID 172.17.4.124@o2ib 0s ago has failed due to network error (5s prior to deadline). req@ffff810133f24800 x1361639653769217/t0 o250->[email protected]@o2ib_0:26/25 lens 368/584 e 0 to 1 dl 1298560772 ref 1 fl Rpc:N/0/0 rc 0/0 LustreError: 3164:0:(client.c:858:ptlrpc_import_delay_req()) @@@ IMP_INVALID req@ffff810106b39c00 x1361639653769218/t0 o253->[email protected]@o2ib_0:26/25 lens 4736/4928 e 0 to 1 dl 0 ref 1 fl Rpc:/0/0 rc 0/0 LustreError: 3164:0:(obd_mount.c:1097:server_start_targets()) Required registration failed for lustre-OST0037: -108 LustreError: 3164:0:(obd_mount.c:1655:server_fill_super()) Unable to start targets: -108 LustreError: 3164:0:(obd_mount.c:1438:server_put_super()) no obd lustre-OST0037 LustreError: 3164:0:(obd_mount.c:147:server_deregister_mount()) lustre-OST0037 not registered The first mds/mgsnode has the mdt mounted. lctl ping and regular TCP/ip works over the ib interface. Did I miss something that the ost needs to join the new mds/mgs configuration?
