Well yes - it shows the device is being held open - lvm2 retries to several
times if the device does not get close - but it doesn't so it refuses o
deactivate.
So if you are sure there is no user - then maybe you have some kpartx
partition this device ?
I'd probably need to see your whole 'dmsetup table'
(at least do a grep for VG_AAA_TEMP/LV_AAA_TEMP minor)
