I am trying to set up a NFS cluster as per the instructions at
http://docs.sun.com/app/docs/doc/820-7821. I've reached the point where I
export disks over iSCSI with COMSTAR, and the process fails. Being new to
OpenSolaris, I'm sure I'm missing something basic.
I have two 2009.06 x86 servers, each with two public NICs (one to the mgmt
network, the other to the client network), and a third NIC connected via
crossover cable to the other server. Each has ha-cluster-full installed.
I think I have disks exported. Here's one server exporting c10t0d0:
datastore1~;itadm list-target
TARGET NAME STATE SESSIONS
iqn.1986-03.com.sun:02:6230a9ff-67d0-e995-9e85-f009c17adab9 online 0
datastore1~;
Here's the other server, where server 1's c10t0d0 is listed as the first target:
datastore2~;iscsiadm list target
Target: iqn.1986-03.com.sun:02:6230a9ff-67d0-e995-9e85-f009c17adab9
Alias: -
TPGT: 1
ISID: 4000002a0000
Connections: 1
Target: iqn.1986-03.com.sun:01:e00000000000.4b2fd513
Alias: -
ISID: 4000002a0000
Connections: 0
On server 2, the initiator, I create links with devfsadm and use format to
check the disks. But not only is the disk from server 1 not listed, the disk
I'm exporting on server 2 (c9d1) isn't listed either.
datastore2~;devfsadm -i iscsi
datastore2~;format < /dev/null
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c8d0 <DEFAULT cyl 60725 alt 2 hd 255 sec 126>
/pci at 0,0/pci-ide at 1f,2/ide at 0/cmdk at 0,0
1. c8d1 <DEFAULT cyl 60797 alt 2 hd 255 sec 126>
/pci at 0,0/pci-ide at 1f,2/ide at 0/cmdk at 1,0
Specify disk (enter its number):
datastore2~;
Shouldn't I also see the disk I'm exporting locally as well as the disk from
server 1?
Both machines in the cluster seem to be aware of all the disks:
/usr/cluster/bin/cldevice list -v
DID Device Full Device Path
---------- ----------------
d1 datastore2:/dev/rdsk/c7t0d0
d2 datastore2:/dev/rdsk/c8d0
d3 datastore2:/dev/rdsk/c8d1
d4 datastore2:/dev/rdsk/c9d1
d5 datastore1:/dev/rdsk/c10t0d0
d6 datastore1:/dev/rdsk/c8t0d0
d7 datastore1:/dev/rdsk/c8t1d0
d8 datastore1:/dev/rdsk/c8t2d0
Should those disks be visible when running "format"?
Thinking I might be too paranoid here, I followed the instructions to create a
mirrored zpool:
datastore2~;zpool create cluster1 mirror /dev/did/dsk/d4s2 /dev/did/dsk/d5s2
cannot open '/dev/did/dsk/d4s2': Device busy
Any suggestions on where I should look, what man pages or tutorials I should
read, etc?
Thanks,
==ml
