Hello I have the following thin volume, which I'd like to delete:
lvdisplay -v /dev/coregroup/c13537_2k
Using logical volume(s) on command line.
--- Logical volume ---
LV Path /dev/coregroup/c13537_2k
LV Name c13537_2k
VG Name coregroup
LV UUID LBPr0i-uac8-i3Co-5B3M-A6Bv-q8iv-kSRLRr
LV Write Access read/write
LV Creation host, time xxxxx.net, 2015-10-14 02:02:45 -0500
LV Pool name corepool
LV Status available
# open 1
LV Size 1.80 TiB
Mapped size 42.11%
Current LE 471808
Segments 1
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 252:6
dmsetup info coregroup-c13537_2k
Name: coregroup-c13537_2k
State: ACTIVE
Read Ahead: 256
Tables present: LIVE
Open count: 1
Event number: 1
Major, minor: 252, 6
Number of targets: 1
UUID: LVM-M8PwSxzGcsZQTtdgzfixsr08ZAlNpAbALBPr0iuac8i3Co5B3MA6Bvq8ivkSRLRr
dmsetup status
coregroup-c13537_2k: 0 3865051136 thin 1627684864 3865042943
The version of the software is:
lvremove --version
LVM version: 2.02.118(2)-RHEL6 (2015-09-08)
Library version: 1.02.95-RHEL6 (2015-09-08)
Driver version: 4.26.0
And the kernel is 3.12.47.
When I run 'lvremove -f /dev/coregroup/c13537_2k' I get the following
error: Logical volume coregroup/c13537_2k contains a filesystem in use.
I also get the same error when I try to deactivate the volume.
fuser doesn't report anything and the volume is not mounted anywhere. I
have also acquired an ftrace trace from executing lvremove but there are
multiple invocation of the dm_ioctl function and I'm not sure which one
is the relevant. So if you tell me what information in particular you
need I'd post it here.
Regards,
Nikolay

Nikolay,
this is a question for linux-lvm.
You're saying the fs is not mounted but the lv is open as of
your lvdisplay output, thus you can't lvremove it.

Right, will know from now on .

How can I see which is the actual user of it? As I stated previously
fuser and lsof didn't show anything relevant. Is there some additional
tools from the lvm suite that I can see to obtain such information?

fuser and lsof can only report open files of active processes.
You should check the following as well:
grep c13537_2k /proc/{mounts,swaps}
dmsetup table|grep 252:6
losetup -a | grep dm-6

Okay, the next time this situation occurs I will do that and
report back (this time to the correct mailing list :) if I find anything?
