Hi,
I probably have the same problem.
It occurs in about 20% of the calls to lvremove,
but can be reproduced reliably using the description bellow.
Symptoms:
$ lvremove vg/lv-snap
Do you really want to remove active logical volume lv-snap? [y/n]: y

Hi,
I have the same problem. lvremove fails to remove snapshot LVs in many
cases (but not 100% of the time).
As a workaround, I am currently using the dmsetup remove trick.
What can we do to fix this problem?
Here are the software versions I’m using:
lvm2 2.02.95-4
udev

Thanks for this hint. I added the -s flag, but I can still reproduce the
snapshot removal problem:
lvremove --verbose -f plana/snap_web
Hello,
After reporting[1] the workaround[2] of calling dmsetup directly to
schroot, Roger Leigh suggested me to make a report against LVM2 or udev.
I don't know where the problem is exactly, but on my system the bug in
100% reproductible:
#+begin_src
root@home:~# lvcreate -L2G -s
Trying not too add too much noise to this bug... I just ran into this
and followed the advice to stop udev, then try to remove the volumes (in
my case they were snapshots created for backup purposes), and it worked.
I'm running stable:
ii dmsetup

Too less information. A swap LV can be in use by a large amount of
things:
- Used as swap.
- Used as resume device.

I had this problem because my old swap LV was listed in
/etc/initramfs-tools/conf.d/resume . I changed it, update-initramfs
-u, reboot, and then I could remove the LV.
