Now, this was a good description, and something reproducible:
rm: Unable to remove directory ld/testsuite/lib: File exists
rm: Unable to remove directory ld/testsuite: File exists
rm: Unable to remove directory ld: File exists
etc.
Note that this does only happen when using the (default) NFSv3
protocol. If you mount NFSv2 (-o vers=2), the rm -rf works okay.
That's a piece of the appropriate truss log of the rm -r on the Sun:
getdents(7, 0x00025220, 1048) = 48
lstat("ld.exp", 0xEFFFF728) = 0
unlink("ld.exp") = 0
getdents(7, 0x00025220, 1048) Err#22 EINVAL
close(7) = 0
chdir("..") = 0
rmdir("lib") = 0
getdents(6, 0x00024DF0, 1048) Err#22 EINVAL
close(6) = 0
chdir("..") = 0
rmdir("testsuite") = 0
getdents(5, 0x000233A8, 1048) Err#22 EINVAL
close(5) = 0
chdir("..") = 0
rmdir("ld") Err#17 EEXIST
The EINVALs are our problem... Here's the tcpdump log of the very
same part. I have removed the timestamps for brevity, since they
aren't relevant here anyway. Note that the readdirplus calls yield an
error 10003.
Doug, can you make any sense out of this?
