Hello list, 

I started playing aroud with Comstar in snv_134. In snv_116 version of ZFS, a 
new hidden property for the Comstar MetaData has been intoduced (stmf_sbd_lu). 
This makes it possible to migrate from legacy (iscsi target daemon) to Comstar 
without data loss, which is great. 

Before this property you always lost the first 64k of your zvol data where 
comstar wrote it's metadata - which is bad.

When testing send/receive with the latest opensolaris I found that the property 
is not replicated. Without the send/receive support, it makes it very difficult 
to use send/receive to perform disaster recovery - why ? Because disk ID's of 
the devices change on the target side, so clients must be reconfigured, which 
is difficult with many clients.

After investigating this, I tried "iscsioptions" - the old style property of 
the legacy target. This is also not replicated. So it seems to be "designed in".

So I wonder - where can I found information which properties are replicated and 
which are not ? 

Can someone help ? 

Regards,
Robert
