Hello!
I have a service in a form of a python script to copy OS profile to a LUKS-encrypted external drive on service stop and
restore from it back on service start. (If anyone is interested, this btrfs-progs
test: https://gist.github.com/ettavolt/b9e94c36a483f6045339c33fd90ce2e8 - might give an idea of the flow)
The service (backup-ask-rbr.service in the logs I'll attach below) is hooked to device connection via udev by adding
SYSTEMD_WANTS device property.
However, there is a race condition when I unplug the drive (e.g. to come with a laptop to a meeting).
1. disk-by-<…>.device is stopped (because unplugged).
2. systemd-cryptsetup@<…>.service is stopped, because it BindsTo=disk-by-<…>.device.
2.1. Fails, because drive is still mounted.
3. Service is stopped, because it BindsTo=<…>.mount, and that has stop propagated from blockdev@dev-mapper-<…>.target.
3.1. Fails, because IO can not go to device.
4. <…>.mount is unmounted.
4.1. Succeeds.
Note, that /dev/mapper/<name> is still there.
Now, when I plug the drive back, systemd tries to activate the main service (due to SYSTEMD_WANTS). Service
BindsTo=<…>.mount, so systemd goes to activate the mount. Mount sees /dev/mapper/<name>, doesn't activate systemd-
cryptsetup@<…>.service, fails. Consequently, the main service fails to start too.
BTW, /dev/sdc seems to be occupied, so the drive gets /dev/sdd (but that's not a problem for cryptsetup&mounts per se).
Things can get up properly on replug if I manually issue cryptsetup close <…> before plugging.
I've solved this race by adding overrides to <…>.mount and blockdev@dev-mapper-<…>.target so that the former
BindsTo=blockdev@dev-mapper-<…>.target and the latter BindsTo=systemd-cryptsetup@<…>.service. With that, things are
properly ordered on unplug:
1. disk-by-<…>.device is stopped (because unplugged).
2. Stop propagates through systemd-cryptsetup@<…>.service, blockdev@dev-mapper-<…>.target, <…>.mount to the main
service.
2.1. Fails to properly stop because of IO failure.
3. <…>.mount successfully unmounts (nothing tries IO).
4. systemd-cryptsetup@<…>.service successfully closes, because unmounted.
And units get up without manual interaction on plug.
What do you think about making systemd-fstab-generator to write BindsTo=blockdev@<…>.target instead of just Requires=,
and also somehow make sure that systemd-cryptsetup@<…>.service is BoundBy blockdev@dev-mapper-<…>.target?
Attached are statuses of device, crypt, mount, and service units after various actions, the units themselves (without
overrides), and journal excerpts after unplugging (with and without overrides).
Thanks
