[Linux-cluster] [PATCH] wrong strings in quorum disk registration.



Hi all,

on the openais based cman-2.0.35-2.el5 the output of "cman_tool nodes"
or "clustat" provides a wrong quorum device name:

[root nodo01 ~]# cman_tool nodes
Node  Sts   Inc   Joined               Name
   0   X      0                        /dev/sdb1��
   1   M      4   2007-01-05 13:03:18  nodo01
   2   X      0                        nodo02

[root nodo01 ~]# clustat
/dev/sdb1�� not found
realloc 924
Member Status: Quorate

  Member Name                        ID   Status
  ------ ----                        ---- ------
  nodo01                                1 Online, Local
  nodo02                                2 Offline
  /dev/sdb1��                       0 Online, Estranged


Looking at the code look like the call to info_call in
cman_register_quorum_device passed a too small by one "inlen" argument
missing the ending \0 of the device name string.
I attached a patch the should fix this, I hope it's correct.

Thanks!

Bye!
