This may have been discussed before, but I didn't quite find a solution.
On a SuSE 9.1 based system, with 2.6.18-vanilla and lustre 1.6.1 (but
also with different versions), I get a segfault for
# cp etc-ro/ypserver.conf /tmp
where /etc-ro is on a lustre fs, and /tmp is tmpfs.
strace reveals what I think the problem is:
listxattr("etc-ro/ypserv.conf", (nil), 0) = 12
listxattr("etc-ro/ypserv.conf", 0x7ffff79ea200, 12) = 12
getxattr("etc-ro/ypserv.conf", "trusted.lov", (nil), 0) = 56
getxattr("etc-ro/ypserv.conf", "trusted.lov", 0x515af0, 56) = 56
setxattr("/tmp/ypserv.conf", "trusted.lov", 0x515af0, 56, ) = -1
EOPNOTSUPP (Operation not supported)
cp tries to copy the EA, can't create that on tmpfs and I guess
doesn't handle the error return gracefully but segfaults. Now that
mostly looks like a cp bug, but I'm also wondering whether internals
of the fs (the "trusted.lov") should be exposed to a regular
userspace application?
