Public bug reported: Since somewhere in the Jan 14-18 range my glusterfs georeplication reports Faulty. Georeplication uses rsync internally, and tracking this this down leads to an exit code 3 out of rsync.
I have no stacktraces myself, but I found this report about the same problem: https://www.spinics.net/lists/gluster-users/msg33568.html with traces: strace rsync : 30743 23:34:47 newfstatat(3, "6737", {st_mode=S_IFDIR|0755, st_size=4096, ...}, AT_SYMLINK_NOFOLLOW) = 0 30743 23:34:47 newfstatat(3, "6741", {st_mode=S_IFDIR|0755, st_size=4096, ...}, AT_SYMLINK_NOFOLLOW) = 0 30743 23:34:47 getdents(3, /* 0 entries */, 131072) = 0 30743 23:34:47 munmap(0x7fa4feae7000, 135168) = 0 30743 23:34:47 close(3) = 0 30743 23:34:47 write(2, "rsync: getcwd(): No such file or directory (2)", 46) = 46 30743 23:34:47 write(2, "\n", 1) = 1 30743 23:34:47 rt_sigaction(SIGUSR1, {SIG_IGN, [], SA_RESTORER, 0x7fa4fdf404b0}, NULL, 8) = 0 30743 23:34:47 rt_sigaction(SIGUSR2, {SIG_IGN, [], SA_RESTORER, 0x7fa4fdf404b0}, NULL, 8) = 0 30743 23:34:47 write(2, "rsync error: errors selecting input/output files, dirs (code 3) at util.c(1056) [Receiver=3.1.1]", 96) = 96 30743 23:34:47 write(2, "\n", 1) = 1 30743 23:34:47 exit_group(3) = ? 30743 23:34:47 +++ exited with 3 +++ The Changelog of glibc mentions that getcwd has been changed: * SECURITY UPDATE: Buffer underflow in realpath() - debian/patches/any/cvs-make-getcwd-fail-if-path-is-no-absolute.diff: Make getcwd(3) fail if it cannot obtain an absolute path - CVE-2018-1000001 and downgrading glibc to (2.23-0ubuntu3) indeed fixes my georeplication problem. 0ubuntu3 is the latest version that is available in the repositories, other than 0ubuntu10. ** Affects: glibc (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1746995 Title: regression in 2.23-0ubuntu10: rsync in glusterfs's georeplication fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1746995/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
