ClearCase fs is (can be) case sensitive. Scenario is a
CC view exported to a FreeBSD machine, doing a build.
make(1) looks for the files BSDmakefile, makefile,
Makefile in that order. Debug trace shows three
NFS_LOOKUP calls, with the first two failing and the
third returning a fhandle.
After processing some other files it comes back to the
same directory, and tries the three files in order
again. Trace shows two NFS_LOOKUPs (for BSDmakefile
and makefile) and then a NFS_GETATTR on the fhandle for
cached Makefile.
sossnt returns NFSERR_STALE, because the InodeTable for
the given inode is empty.
It appears that the NFS_LOOKUP of makefile calls
file_getattr which in turn calls file_readattr, which does:
if (myfindfirst (path, &findbuf) != 0)
{
/* not successful */
if ((nodeid = pntoin (path)) != -1)
inremnode (nodeid);
DBGPRT0 (inode, "return false A");
return FALSE;
}
So it appears that since pntoin is not case sensitive
and the lookup of makefile fails, Makefile gets removed
from the inode table.
