I'm trying to debug why dmraid won't deactivate this raid set and am
very confused by the code I see. Hopefully someone can shed some light
on this.
change_set() calls deactivate_set() which calls dm_remove(), which calls
run_task() in lib/activate/devmapper.c. run_task() looks like this:
if (ret &&
DM_DEVICE_CREATE == type)
ret = dmraid_uuid(lc, rs, uuid, DM_UUID_LEN) &&
dm_task_set_uuid(dmt, uuid) &&
dm_task_run(dmt);
Now that looks to me like the only kind of task it will run is a create
task, not a remove task, like the one it is being asked to do. This
code looks like it will never work, as if the removal code was never
completed, yet I know that dmraid -an does work normally, so what gives?
