So it's likely a time to look through 'dmesg' output if there is not something suspicious ?

Kernel bug/report showing some error behavior which may lead to openned descriptor being leaked?

Is there anything in  /sys/block/dm-49/holders ?

cat /proc/self/mountinfo | grep 253:49 ?



I tried before, but found nothing

[root@orapr2 ~]# ll /sys/block/dm-49/holders
total 0

[root@orapr2 ~]# cat /proc/self/mountinfo | grep 253:49
[root@orapr2 ~]# 

last lines of dmesg contain
dlm: closing connection to node 1
dlm: got connection from 1

That refers to when we restarted the passive node yesterday
Nov 26 17:23:58 orapr2 kernel: dlm: closing connection to node 1
