Hi,
To learn what I'm doing, I set up two OpenSolaris VMs and worked to cluster
them. This let me learn much faster than real hardware.
For anyone following along, the key in Augustus' statement that I needed an
iscsi connection to both the local disk and the remote disk. Once I told
iscsiadm on each node to look at both the local and remote interconnect IPs,
everything connected. (If you set up a cluster like this, read the example
closely as well as the linked articles explaining how all the pieces work.)
I've hit another snag, though. I can't online the cluster resource.
# /usr/cluster/bin/clresourcegroup data3
clresourcegroup: (C198212) Unrecognized subcommand - "data3".
clresourcegroup: (C101856) Usage error.
...(usage info)
Reading the clresource manual page, it seemed that what I wanted was
"clresourcegroup data3." That seemed to work, and allowed me to create a
resource to manage the iscsi-mirrored zpool "data3" and put it into management
mode, as per the example. But then I try to online this group:
#/usr/cluster/bin/clresourcegroup online data3
clresourcegroup: (C748634) Resource group data3 failed to start on chosen node
and might fail over to other node(s)
clresourcegroup: (C135343) No primary node could be found for resource group
data3; it remains offline
It appears that this error shows up when mixing zone and global clusters, but
"cluster show" indicates that I have no zone clusters.
Obviously, I'm missing something. Should the first "clresourcegroup" command
have worked without a subcommand? Or am I missing something else that would
let me online the group?
Thanks,
==ml
