I've got a USB-attached SATA drive with 2 partitions, and I think a thumb drive as well. Normally, only one of the SATA partitions is mounted. Twice now, I'm using the SATA drive, and I get I/O errors, and see that both partitions are mounted, and I've normal usage of the one which _should_ be mounted. Doesn't clear up until I manually umount, mount, etc. Tonight I find the following in /var/log/messages: 2013-12-07T22:55:30.616422-05:00 binkenlights systemd[1]: Unmounting /data5... 2013-12-07T22:55:30.656153-05:00 binkenlights umount[29066]: umount: /data5: target is busy. 2013-12-07T22:55:30.656377-05:00 binkenlights umount[29066]: (In some cases useful info about processes that use 2013-12-07T22:55:30.656430-05:00 binkenlights umount[29066]: the device is found by lsof(8) or fuser(1)) 2013-12-07T22:55:30.656494-05:00 binkenlights systemd[1]: data5.mount mount process exited, code=exited status=32 2013-12-07T22:55:30.656812-05:00 binkenlights systemd[1]: Failed unmounting /data5. 2013-12-07T22:55:30.896650-05:00 binkenlights mtp-probe: checking bus 4, device 4: "/sys/devices/pci0000:00/0000:00:14.0/usb4/ 4-2" 2013-12-07T22:55:30.914347-05:00 binkenlights mtp-probe: bus: 4, device: 4 was not an MTP device 2013-12-07T22:55:32.030377-05:00 binkenlights systemd[1]: Found device ST2000DM001-1E6164. 2013-12-07T22:55:32.034794-05:00 binkenlights systemd[1]: Found device ST2000DM001-1E6164. 2013-12-07T22:55:32.034953-05:00 binkenlights systemd[1]: Starting File System Check on /dev/disk/by-id/ata-ST2000DM001-1E6164 _W1E4R7CL-part2... 2013-12-07T22:55:32.221292-05:00 binkenlights systemd-fsck[29094]: /dev/sde2: clean, 219049/54992896 files, 38956703/219942400 blocks 2013-12-07T22:55:32.298043-05:00 binkenlights systemd[1]: Started File System Check on /dev/disk/by-id/ata-ST2000DM001-1E6164_ W1E4R7CL-part2. 2013-12-07T22:55:32.298506-05:00 binkenlights systemd[1]: Mounting /data6... 2013-12-07T22:55:32.388914-05:00 binkenlights systemd[1]: Mounted /data6. /data5 is the one I normally have mounted, and the above operations screwed me up files become inaccessible to me. /data6 is normally not mounted, but after (whatever systemd is up to), it is mounted and stays that way until I manually fix it. I've googled, and grepped half my fs to find signs of what is going on here, but no luck.
