Bug occurred during 'zypper dup' (openSUSE Leap 15.0 -> 15.1). The machine in question, however, does not use BTRFS at all: --- snip --- box:~ # grep btr /etc/fstab box:~ # mount | grep btr box:~ # --- snap --- Some additional information: --- snip --- (761/898) Installing: btrfsmaintenance-0.4.2-lp151.1.1.noarch .............................................<100%>[\] box:~ # ps auxwww [...] root 8446 0.0 0.1 57256 9332 pts/1 S+ 13:44 0:00 rpm --root / --dbpath /var/lib/rpm -U --percent --noglob --force --nodeps -- /var/cache/zypp/packages/deflektor_oss/noarch/btrfsmaintenance-0.4.2-lp151.1.1.noarch.rpm root 8496 0.0 0.0 11980 2816 pts/1 S+ 13:44 0:00 /bin/sh /var/tmp/rpm-tmp.WnJcBQ 1 root 8531 0.0 0.0 11980 1904 pts/1 S+ 13:44 0:00 /bin/sh /var/tmp/rpm-tmp.WnJcBQ 1 root 8532 0.0 0.0 60224 6164 pts/1 S+ 13:44 0:00 /usr/bin/systemctl try-restart btrfsmaintenance-refresh.service btrfsmaintenance-refresh.path btrfs-balance.service btrfs-balance.timer btrfs-defrag.service btrfs-defrag.timer btrfs-scrub.service btrfs-scrub.timer btrfs-trim.service btrfs-trim.timer box:~ # lsof -p 8532 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME systemctl 8532 root cwd DIR 254,2 4096 2 / systemctl 8532 root rtd DIR 254,2 4096 2 / systemctl 8532 root txt REG 254,2 182416 531004 /usr/bin/systemctl systemctl 8532 root mem REG 254,2 1356080 3932198 /lib64/libm-2.26.so systemctl 8532 root mem REG 254,2 141560 533143 /usr/lib64/libudev.so.1.6.6 systemctl 8532 root mem REG 254,2 64208 530729 /usr/lib64/libjson-c.so.3.0.1 systemctl 8532 root mem REG 254,2 30896 525373 /usr/lib64/libargon2.so.1 systemctl 8532 root mem REG 254,2 354144 528070 /usr/lib64/libdevmapper.so.1.03 systemctl 8532 root mem REG 254,2 30840 524568 /usr/lib64/libuuid.so.1.3.0 systemctl 8532 root mem REG 254,2 18824 3932195 /lib64/libattr.so.1.1.0 systemctl 8532 root mem REG 254,2 575808 524531 /usr/lib64/libpcre.so.1.2.9 systemctl 8532 root mem REG 254,2 337224 530647 /usr/lib64/libcryptsetup.so.12.3.0 systemctl 8532 root mem REG 254,2 338976 525529 /usr/lib64/libblkid.so.1.1.0 systemctl 8532 root mem REG 254,2 268576 524634 /usr/lib64/libseccomp.so.2.3.2 systemctl 8532 root mem REG 254,2 35424 3932224 /lib64/libacl.so.1.1.2253 systemctl 8532 root mem REG 254,2 130208 530939 /usr/lib64/libgpg-error.so.0.24.0 systemctl 8532 root mem REG 254,2 18616 3932192 /lib64/libdl-2.26.so systemctl 8532 root mem REG 254,2 1164832 529454 /usr/lib64/libgcrypt.so.20.2.2 systemctl 8532 root mem REG 254,2 84352 525302 /usr/lib64/liblz4.so.1.8.0 systemctl 8532 root mem REG 254,2 235576 525270 /usr/lib64/liblzma.so.5.2.3 systemctl 8532 root mem REG 254,2 97200 3932312 /lib64/libresolv-2.26.so systemctl 8532 root mem REG 254,2 42120 3934078 /lib64/librt-2.26.so systemctl 8532 root mem REG 254,2 18984 526567 /usr/lib64/libcap.so.2.25 systemctl 8532 root mem REG 254,2 159456 3934083 /lib64/libselinux.so.1 systemctl 8532 root mem REG 254,2 2034848 3932178 /lib64/libc-2.26.so systemctl 8532 root mem REG 254,2 140688 3932289 /lib64/libpthread-2.26.so systemctl 8532 root mem REG 254,2 2302168 531028 /usr/lib/systemd/libsystemd-shared-234.so systemctl 8532 root mem REG 254,2 180056 3934066 /lib64/ld-2.26.so systemctl 8532 root 0r FIFO 0,12 0t0 50830 pipe systemctl 8532 root 1w FIFO 0,12 0t0 52546 pipe systemctl 8532 root 2w FIFO 0,12 0t0 52546 pipe systemctl 8532 root 3u unix 0xffff8801f5e10400 0t0 50858 type=STREAM box:~ # strace -p 8532 strace: Process 8532 attached ppoll([{fd=3, events=POLLIN}], 1, NULL, NULL, 8 box:~ # ps -elf | head -1;
