I've just tested with 1.3.9. It has both problems, as well; they're not
unique to the 1.4 branch.
Thanks,

I believe I've narrowed down the setuid issue to a glitch in hardlink
handling. It was happening in the case of /usr/bin/sudoedit apparently
because sudoedit is a hardlink to sudo. When cp -a does the hardlink, it
wipes out the setuid bit. I'm fairly certain this is what's happening, as I
tried the cp -a with a bin directory that had sudo removed, and GlusterFS
happily preserved the setuid bit. Try again with sudo present, it fails.
Try again with sudo and sudoedit not being hardlinks, and it works!
great clue! just curious if this was not observed in the previous version
(1.3.x) as well?
Is anyone having any luck with "cp -a"'s inability to preserve directory
permissions? In case it helps, here's an strace snippet from "cp -a blah
/beast" where blah is an empty directory, mode 755, and /beast is my
GlusterFS:
there is no chmod/fchmod call issued by cp in the strace. Again, is this
observed in the new mainline and not in previous versions?
