Thanks Sebastian, I didn't check that out. I'll start following that bug.
----- Mail Original ----- De: "Sebastien Piechurski" <[email protected]> À: [email protected], "lustre-discuss" <[email protected]> Envoyé: Jeudi 16 Juin 2011 15h30:38 GMT +01:00 Amsterdam / Berlin / Berne / Rome / Stockholm / Vienne Objet: RE: [Lustre-discuss] Path lost when accessing files Hi, This problem is documented in bug 23978 (http://bugzilla.lustre.org/show_bug.cgi?id=23978). To summarize: the fortran runtime is making a call to getcwd() to get the full path to a file which was given as a relative path. Lustre sometimes fail to answer to this syscall, which returns a non initialized buffer and an error code, BUT the fortran runtime does not test the getcwd() return code, and uses the buffer as-is. The uninitialized buffer is what you see as " @", followed by the relative path. A patch is currently inspected. > -----Original Message----- > From: [email protected] > [mailto:[email protected]] On Behalf Of > [email protected] > Sent: jeudi 16 juin 2011 12:17 > To: lustre-discuss > Subject: [Lustre-discuss] Path lost when accessing files > > Hi Lustre users, > > we actually a little problems with jobs running on our > cluster and using Lustre.
