Hello, I have a new Lustre cluster based on Lustre 2.10.0/ZFS 0.7.0 on Centos 7.3 Lustre FS creation went smooth. When I tryed then to mount from the clients, Lustre is not able to mount any of the OSTs. It stops at MGS/MDT level.
this is from the client side: mount.lustre: mount 192.168..48.254@tcp2:/scratch12 at /reg/data/scratch12 failed: Invalid argument This may have multiple causes. Is 'scratch12' the correct filesystem name? Are the mount options correct? Check the syslog for more info.

So I tried to engage tcpdump: 17:58:53.745610 IP psana1510.pcdsn.1023 > psanamds12.pcdsn.cyborg-systems: Flags [S], seq 1356843681, win 29200, options [mss 1460,sackOK,TS val 284847388 ecr 0,nop,wscale 7], length 0 17:58:53.745644 IP psanamds12.pcdsn.cyborg-systems > psana1510.pcdsn.1023: Flags [R.], seq 0, ack 1356843682, win 0, length 0 17:58:58.757421 ARP, Request who-has psanamds12.pcdsn tell psana1510.pcdsn, length 46 17:58:58.757441 ARP, Reply psanamds12.pcdsn is-at 00:1a:4a:16:01:56 (oui Unknown), length 28 OSS, nothing in the log file or in tcpdump lustre client is 2.9 and the server 2.10.0 I have no firewall running and no SElinux this never happened to me before. I am usually running older lustre versions on clients but I never had this problem before. Any hint ? thank you very much Rick _______________________________________________ lustre-discuss mailing list lustre-discuss@lists.lustre.org http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
