Lvm – Can’t remove open logical volume

lvm

When I try to remove a logical volume I get the message

#lvremove /dev/my-volumes/volume-1 
Can't remove open logical volume "volume-1"

#lvchange -an -v /dev/my-volumes/volume-1 
Using logical volume(s) on command line
/dev/dm-1: read failed after 0 of 4096 at 0: Input/output error
Deactivating logical volume "volume-1"

#lvremove -vf /dev/my-volumes/volume-1

#lvs

How can I force the removal of this volume?

Thanks,

What does the logical volume contain? Is it a filesystem (I accidentally wrote partition)? Could it be it's mounted? In that case:

umount /dev/my-volumes/volume-1

Does it have any active snapshots?

Edit: try lvchange -an -v /dev/my-volumes/volume-1 and lvremove -vf /dev/my-volumes/volume-1.

Edit 2: please post 'lvs'.

Edit 3: Try this with some other problematic volume. It's not the cleanest option but according to this site it may work, and it's less problematic than rebooting anyway.

dmsetup remove my--volumes-volume--number
lvremove /dev/my-volumes/volume-number
