<P><FONT face=Arial size=2>Hi list,</FONT> </P>
<P><FONT face=Arial size=2>i've successfully implemented a three-node setup with
an offsite node via drbd stacked-device as explained in the
users-guide</FONT></P>
<P><FONT face=Arial size=2>( </FONT><A
href="http://www.drbd.org/users-guide/s-pacemaker-stacked-resources.html"><U><FONT
face=Arial color=#0000ff
size=2>http://www.drbd.org/users-guide/s-pacemaker-stacked-resources.html</FONT></U></A><FONT
face=Arial size=2> )</FONT> </P>
<P><FONT face=Arial size=2>the offsite drbd-device status is always 'secondary'
because it has to stay in sync with the 'primary' (stacked) device managed by
pacemaker crm.</FONT></P>
<P><FONT face=Arial size=2>afaik 'secondary' devices cannot be
mounted/accessed.</FONT> </P>
<P><FONT face=Arial size=2>so, how can i access the offsite data, assumed all
nodes in my ha-cluster failed?</FONT> </P>
<P><FONT face=Arial size=2>how to handle the different states, the
offsite-device can be in and how to do a recovery from it?</FONT> <BR><FONT
face=Arial size=2>i can think these:</FONT> <BR><FONT face=Arial size=2>
- cs:WFConnection ro:Secondary/Unknown
ds:UpToDate/DUnknown</FONT> <BR><FONT face=Arial size=2> -
cs:WFConnection/Unknown ro:Secondary/Primary
ds:Outdated/DUnknown</FONT> <BR><FONT face=Arial size=2> -
cs:WFConnection/Unknown ro:Secondary/Primary
ds:Consistent/DUnknown</FONT> <BR><FONT face=Arial size=2> -
cs:WFConnection/Unknown ro:Secondary/Primary
ds:Inconsistent/DUnknown</FONT> </P><BR>
<P><FONT face=Arial size=2>is there a possibility to make the data on the
offsite node permanently available (read only)?</FONT> <BR><FONT face=Arial
size=2> e.g. so i can always 'clone' my production data to my
test-environment from the state:</FONT> <BR><FONT face=Arial
size=2> cs:Connected ro:Secondary/Primary
ds:UpToDate/UpToDate</FONT> </P><BR>
