This is probably the same problem as bug 648. Upgrading to a more recent kernel (2.2.10 that comes with 6.1 seems to work fine) should help. Actually, I had to install the glibc from the 6.1 distribution as well, so the problem might be in the glibc and not the kernel. This combination seems to solve the problem: kernel-2.2.12-20 glibc-2.1.2-11 |
Performing a "diff -qr <dir1> <dir2>" fails when either of the two directories are NFS mounted. According to an strace of diff: ---------------------------------------- open("ndd.sav", O_RDONLY|O_NONBLOCK|0x10000) = 3 fstat(3, {st_mode=0, st_size=0, ...}) = 0 fcntl(3, F_SETFD, FD_CLOEXEC) = 0 brk(0x805d000) = 0x805d000 lseek(3, 0, SEEK_CUR) = 0 getdents(3, 0 60 12 60 28 60 44 60 /* 4 entries */, 3933) = 60 lseek(3, 0, SEEK_CUR) = -1 EPERM (Operation not permitted) getdents(3, /* 0 entries */, 3933) = 0 close(3) = 0 write(2, "diff: ", 6diff: ) = 6 write(2, "ndd.sav: Operation not permitted"..., 33ndd.sav: Operation not permitted ) = 33 close(1) = 0 _exit(2) = ? ---------------------------------------- It appears that diff is trying to do an lseek on the directory to rewind it but this returns an error.
