I tried before, but found nothing

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

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