Operating Systems Solaris Sharing a physical disk with an LDOM Post 303042253 by hicksd8 on Thursday 19th of December 2019 04:16:14 PM

One thing for sure is that only one of the nodes (Solaris 11 Global or Solaris 10 LDOM) can have control of the volume. In any situation, having two operating systems writing to a volume simultaneously is a recipe for instant filesystem corruption. One operating system must control file opening, locking, etc. Even in a cluster scenario using dual tailed storage, a major function of the cluster suite is to control which node has exclusive control of the volume and effect disciplined failover when necessary.

Therefore, like any two nodes, one option is to mount the volume on one node, configure a NFS share on that node, and mount the volume using a NFS client from the second node. The first node then controls ALL activity on the volume.

VOTEQUORUM_LEAVING(3)				    Corosync Cluster Engine Programmer's Manual 			     VOTEQUORUM_LEAVING(3)

NAME
votequorum_leaving - Tell other nodes that we are leaving the cluster SYNOPSIS
#include <corosync/votequorum.h> int votequorum_leaving(votequorum_handle_t handle); DESCRIPTION
The votequorum_leaving function is used to tell the other nodes in the cluster that this node is leaving. They will (when the node actually leaves) reduce quorum to keep the cluster running without this node. This function should only be called if it is known that the node is being shut down for a known reason and could be out of the cluster for an extended period of time. Normal behaviour is for the cluster to reduce the total number of votes, but NOT expected_votes when a node leave the cluster, so the clus- ter could become inquorate. This is correct behaviour and is ther eto prevent split-brain. Do NOT call this function unless you know what you are doing. RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is returned. ERRORS
The errors are undocumented. SEE ALSO
