[Lustre-discuss] Lustre 2.5.2 Client Errors
Hello Everyone, We're trying to run a cluster image on Lustre filesystem version 2.5.2 and repeatedly seeing the following message. Haven't seen anything bizarre on this machine other than this: 2014-08-22T13:52:01+07:00 node01 kernel: LustreError: 4271:0:(namei.c:530:ll_lookup_ it()) Tell Peter, lookup on mtpt, it open 2014-08-22T13:52:01+07:00 node01 kernel: LustreError: 4271:0:(namei.c:530:ll_lookup_it()) Skipped 128 previous similar messages This doesn't happen to our desktop Lustre clients. I'm wondering if anyone has any idea what this means. Thanks, Murshid Azman. ___ Lustre-discuss mailing list Lustre-discuss@lists.lustre.org http://lists.lustre.org/mailman/listinfo/lustre-discuss

Murshid, Does the error message actually have Tell Peter, lookup on mtpt, it open text in it? If so, one of the funnier Lustre error messages to be sure. --Jeff On Fri, Aug 22, 2014 at 12:28 AM, Murshid Azman murshid.az...@gmail.com wrote: Hello Everyone, We're trying to run a cluster image on Lustre filesystem version 2.5.2 and repeatedly seeing the following message.

I'm wondering if anyone has any idea what this means. This is one of those impossible condition has been met messages. Essentially it means that we got a lookup call for a mountpount, which should not happen because it's a mountpoint, so it's always valid and pinned in memory at the very least. What kernel do you use? anything else interesting about this client - e.g. NFS rexport?
