A disk was removed and it was not removed cleanly

Removed the block devices
root@linux:~ # echo 1 > /sys/block/sde/device/delete
root@linux:~ # echo 1 > /sys/block/sdk/device/delete
root@linux:~ # echo 1 > /sys/block/sdq/device/delete
root@linux:~ # echo 1 > /sys/block/sdw/device/delete
I was able to remove the device that device-mapper used but I was not able to remove the device with the partition
root@linux:~ # dmsetup remove disk2
root@linux:~ # dmsetup remove disk2p1
device-mapper: remove ioctl failed: Device or resource busy
Command failed
I had a filesystem using the device /dev/devvg/u01lv so I had to remove it before I was able to remove the device with the partition
root@linux:~ # dmsetup remove devvg-u01lv
root@linux:~ # dmsetup remove disk2p1
