Accessing some files which appear (from a directory listing for example) to have been stored correctly results in 'Bad file descriptor'. This is with a freshly checked and clean filesystem. I say 'clean', but after fsck declares it clean, another pass through fsck will diagnose further errors. This is without mounting the filesystem between passes. I ran a few simple tests and was able to ascertain that the open(2) and read(2) system calls don't return errors but fstat(2) does return EBADF. su-2.05b# ls | grep 1071701821.78602.aether.uk.clara.net 1071701821.78602.aether.uk.clara.net su-2.05b# ls 1071701821.78602.aether.uk.clara.net ls: 1071701821.78602.aether.uk.clara.net: Bad file descriptor Any assistance in diagnosing this would be greatly appreciated.
