Thanks Herv

I’ve checked the output of command “lvs”.

The output from the server where the problem “State change failed: (-12)
Device is held open by someone” is still exist.

[root at abaco-a bin]# lvs --noheadings

  lnpdb    vgdrbd0 -wi---   2.00G

  mysql    vgdrbd0 -wi---   6.00G

[root at abaco-a bin]# lvs --noheadings -o lv_attr



The output from the server where problem doesn’t exist.

[root at elap2A bin]# lvs --noheadings -o lv_attr

  /dev/drbd0: open failed: Wrong medium type

 [root at elap2A bin]# lvs --noheadings

  /dev/drbd0: open failed: Wrong medium type

Any idea what could be wrong here?

*Maybe you should check LV attributs:
$ lvs --noheadings -o lv_attr $LVM_VG/$LVM_LV
$ lvchange -an $LVM_VG/$LVM_LV
$ man lvchange
