https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D207838 Bug ID: 207838 Summary: [zfs] getcwd fails with permission denied under load Product: Base System Version: 10.2-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: h2+fbsdports@fsfe.org I have a machine running a large number of nightly builds and unit tests ev= ery 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/GEN= ERIC amd64 The system is running a ZFS mirror on two SSDs and the relevant datasets ar= e: 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! --=20 You are receiving this mail because: You are the assignee for the bug.=
