Hello,
I'm unable to deactivate an lvm.
My system is RHEL 6.5 with lvm2-2.02.100-8.el6.x86_64 and kernel
2.6.32-431.29.2.el6.x86_64
I get error code 5 with message
Logical volume VG_AAA_TEMP/LV_AAA_TEMP in use.
You can find output of
lvchange -d -d -d -d -d -d -an VG_AAA_TEMP/LV_AAA_TEMP
here:
https://drive.google.com/file/d/0BwoPbcrMv8mvTjlBMkRUbG9nczA/view?usp=sharing
Not really accessible.
But anyway - if you have problem with 'semaphore' resouces - you could
'recycle' old ones -
'dmsetup udevcomplete_all'
Of course it's hard to guess what experiments are you doing and would could
lead to uncompleted cockies (stuck udev scans)
Do you happen to have some suspend devices in your table ?
(dmsetup info -c should show them)
[root@orapr2 ~]# lvs VG_AAA_TEMP/LV_AAA_TEMP
LV VG Attr LSize Pool Origin Data% Move Log
Cpy%Sync Convert
LV_AAA_TEMP VG_AAA_TEMP -wi-ao---- 1020.00m
How can I see the responsible for the reference that apparently keeps it open?
Open count: 1
so I can check and eventually fix??
dmsetup ls --tree
is usually good in shows deps between devs (i.e. target A holds target B)

Zdenek
