You can do a quick check with 2.10.5 client by mounting lustre on MDS if you do not have free node to install 2.10.5 client.
Do you have lnet configured with IB or 10GE? LNet defaults to tcp if not set. Can it be you are connected through slow management network? Alex.

I noticed very slow performances couple of MB/sec when RHEL6 Lustre clients 2.8.0 are writing to the fielsystem. Could it be a Lustre version problem server vs client ? I have no errors either on server or client side that can debug it further... thanks Rick _______________________________________________ lustre-discuss mailing list [email protected] https://urldefense.proofpoint.com/v2/url?u=http-3A__lists.lustre.org_listinfo.cgi_lustre-2Ddiscuss-2Dlustre.org&d=DwIGaQ&c=gRgGjJ3BkIsb5y6s49QqsA&r=23V5nhLj03jeTboyg6QveA&m=ABK5Lf73Df1JeZ-ryuh87ds4a5qoTk1gcookZ1auOuU&s=3gW-gvhmg4r0oQv3isx4u1P2TBHOzyDeFC-MZoxR68Y&e= _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
