[Linux-cluster] clvmd mirroring problems on split-site SAN (2 node cluster) - cpg_dispatch failed: SA_AIS_ERR_LIBRARY

[Pieter Baele]

Hi,

After doing a lot of research on the several ways to mirror a device
from one LUN to another on another side,
I had this problem:

Feb  2 16:42:49 x cmirrord[3682]: cpg_dispatch failed: SA_AIS_ERR_LIBRARY
Feb  2 16:42:49 x cmirrord[3682]: cpg_dispatch failed: SA_AIS_ERR_LIBRARY
Feb  2 16:42:49 x cmirrord[3682]: cpg_dispatch failed: SA_AIS_ERR_LIBRARY
Feb  2 16:42:49 x cmirrord[3682]: cpg_dispatch failed: SA_AIS_ERR_LIBRARY

Feb  2 16:42:49 x cmirrord[3682]: cpg_dispatch failed: SA_AIS_ERR_LIBRARY
Feb  2 16:42:49 x cmirrord[3682]: cpg_dispatch failed: SA_AIS_ERR_LIBRARY
Feb  2 16:42:49 x cmirrord[3682]: cpg_dispatch failed: SA_AIS_ERR_LIBRARY

............


What does it mean and could be the reason?

clustat on the one node shows bode online, on the other one is offline...
