I have a machine running a large number of nightly builds and unit tests every night, maybe more than 8000 targets/tests in all compiler/flag combinations. Every once in a while (on average maybe one per night) a random one of the builds fails with: gmake: getcwd: Permission denied Also sometimes the build of the manual (a python process), fails with: os.path.join(os.getcwd(), 'dummy'), OSError: [Errno 13] Permission denied The system: FreeBSD <snip> 10.2-RELEASE FreeBSD 10.2-RELEASE #0 r286666: Wed Aug 12 15:26:37 UTC 2015 root@releng1.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC amd64 The system is running a ZFS mirror on two SSDs and the relevant datasets are: zssdroot/tmp on /tmp (zfs, local, noatime, nosuid, nfsv4acls) zssdroot/nightly-builds on /usr/home/mi/h4nn3s/nightly-builds (zfs, local, noatime, nfsv4acls) -> the /tmp is not a tmpfs The situation is a little annoying, because it permanently produces false positives in the build matrix... Anything I can do to help diagnose / fix this? Thank you for your help!
^Triage: I'm sorry that this PR did not get addressed in a timely fashion. By now, the version that it was created against is long out of support. As well, many newer versions of ZFS have been imported. Please re-open if it is still a problem on a supported version.
