Begin forwarded message: Date: Tue, 5 Dec 2017 09:04:51 +0100 From: Gerrit K=FChn To: freebsd-fs@freebsd.org Subject: 100.chksetuid handging on nfs mounts Hello all, I just found that the daily security job on a system here was hanging on chksetuid due to a defunct nfs server. Specifically, it turned out that it was hanging on this find: --- find -sx / /dev/null -type f \( -perm -u+x -or -perm -g+x -or -perm -o+x \) \( -perm -u+s -or -perm -g+s \) -exec ls -liTd \{\} \+ --- My understanding up to now was that "-x" should prevent find from accessing mounted nfs dirs (/ is on local disk, the hanging nfs mounts are somewhere under /data/...). Why does the thing still hang, and how can I prevent this? cu Gerrit _______________________________________________ freebsd-fs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-fs To unsubscribe, send any mail to "freebsd-fs-unsubscribe@freebsd.org"
