[Lustre-discuss] Any updates to the base CentOS 5 distro required?
I am trying to install lustre on a CentOS 5 fresh off the DVD install. (No updates) I am also using Lustre 1.6.4.1. I can''t seem to get the OSS or a client to talk to an MGC on a different machine. The networking looks correct, and I can ping between the boxes, but I cannot do a lctl ping to the remote machine. It comes back with an I/O error. Does the bare bones CentOS need to be updated for lustre to function correctly? Thanks! -- Andrew -------------- next part -------------- An HTML attachment was scrubbed...

I do on the mgs side. # lctl list_nids 192.168.135.81 at tcp 192.168.135.80 at tcp1 I also installed an OST on the MGS, and mounted it with no problems. I then mounted the client on that machine as well to test it and it mounts fine and I can write into the OST that is exported from the MGS machine. As I was unsure if I needed to patch, I wiped the OSS machine back to a clean OS and was getting ready to patch it. I won''t do that now, I will just install lustre again and try again. -- Andrew> -----Original Message----- > From: Cliff.White at Sun.COM [mailto:Cliff.White at Sun.COM] > Sent: Tuesday, January 15, 2008 4:15 PM > To: Lundgren, Andrew > Cc: ''Lustre-discuss at clusterfs.com'' > Subject: Re: [Lustre-discuss] Any updates to the base CentOS > 5 distro required? > > Lundgren, Andrew wrote: > > I am trying to install lustre on a CentOS 5 fresh off the > DVD install. > > (No updates) > > > > I am also using Lustre 1.6.4.1. > > > > I can''t seem to get the OSS or a client to talk to an MGC on a > > different machine.

Andrew, is lustre modules loaded? can you show error messages from console and /var/log/messages about it ?

I found the problem, iptables was blocking the connections. Will lustre function with iptables enabled? Do I need to open more than port 988 for lustre to function?

Do I need to open more than > port 988 for lustre to function?You need 988 open for incoming connections on the client, OSS, and MDS nodes. LNET will create 3 outgoing connections on available reserved ports to each client/server pair, starting with 1023, 1022, and 1021, unless those are used by something else.> > -----Original Message----- > > From: Alexey.Lyashkov at Sun.COM [mailto:Alexey.Lyashkov at Sun.COM] > > Sent: Wednesday, January 16, 2008 5:02 AM > > To: Lundgren, Andrew > > Cc: ''Lustre-discuss at clusterfs.com'' > > Subject: Re: [Lustre-discuss] Any updates to the base CentOS > > 5 distro required? > > > > Andrew, > > > > is lustre modules loaded? can you show error messages from > > console and /var/log/messages about it ? > > > > On Tue, 2008-01-15 at 15:25 -0700, Lundgren, Andrew wrote: > > > I am trying to install lustre on a CentOS 5 fresh off the > > DVD install. > > > (No updates) > > > > > > I am also using Lustre 1.6.4.1. > > > > > > I can''t seem to get the OSS or a client to talk to an MGC on a > > > different machine.
