Hi,
*
**Can we share the iSCSI data storage domain across multiple clusters in
the same datacenter?*
Following are the setup details which I tried.
- One datacenter, Say DC1
- in DC1, two clusters, say CL1 and CL2
- In CL1, one host, say H1. And in CL2 one host, say H2
- iSCSI Data Storage domain is configured where external storage
LUNs are exported to host H1(A host in CL1 of Datacenter).
While adding H1 to CL1 is succeeded; addition of H2 in CL2 is failing
with following error in vdsm.log.

no. you can access a storage domain from multiple clusters in same DC.
which type of storage? could it be its "protecting" shared access to the DC?
is moving the host to same cluster as the SPM resolving the issue for
you (it shouldn't)

no. you can access a storage domain from multiple clusters in same DC.
[Santosh]
That is my understanding also.
which type of storage?
[Santosh] 'Storage' is of
'iSCSI' type. Domain type is 'Data (Master)'
could it be its "protecting" shared access to the DC?
[Santosh] How should I find it out?
is moving the host to same cluster as the SPM resolving the issue
for
you (it shouldn't)
[Santosh] Moving the host to the same cluster as that of SPM
did not
resolve the issue.
Thanks for the reply.

**Can we share the iSCSI data storage domain across multiple clusters in
the same datacenter?*
Following are the setup details which I tried.
- One datacenter, Say DC1
- in DC1, two clusters, say CL1 and CL2
- In CL1, one host, say H1. And in CL2 one host, say H2
- iSCSI Data Storage domain is configured where external storage
LUNs are exported to host H1(A host in CL1 of Datacenter).
While adding H1 to CL1 is succeeded; addition of H2 in CL2 is failing
with following error in vdsm.log.

[Santosh] Moving the host to the same cluster as that of SPM did not
resolve the issue.
and if you move the SPM host to maint, does the 2nd host able to become
an SPM/access the storage (which would indicate an issue with storage
side 'protection'.
else, are you sure all hosts can access the storage?
Thanks for the reply.

and if you move the SPM host to maint, does the 2nd host able to become
an SPM/access the storage (which would indicate an issue with storage
side 'protection'.
[Santosh:1] After moving SPM host to maint, 2nd host is
able to become
SPM an access the storage.
[Santosh:1] I will check the storage side protection.
else, are you sure all hosts can access the storage?
