this:<SPAN style="mso-spacerun: yes"> </SPAN>We have a SAN project coming
up but we do not have the SAN or a similar type shared storage device
available.<SPAN style="mso-spacerun: yes"> </SPAN>We have the node
machines on hand and are trying to work through the GFS implementation as we are
new to GFS (We have run RedHat Linux since version 5.0 and all the flavors in
between.).<SPAN style="mso-spacerun: yes"> </SPAN>We have tried to
simulate the SAN environment by utilizing the GNBD software and we have followed
the instructions available at:<SPAN style="mso-spacerun: yes">

color=#000000><FONT face="Times New Roman">We have not had any problems getting
the shared devices, pools, and filesystems created as followed in the
documentation.<SPAN style="mso-spacerun: yes"> </SPAN>What we have
happening is that when we mount the GFS filesystem on one node and then we try
and mount the filesystem on the second node, the second node will hang when
issued the command to mount the filesystem.<SPAN
style="mso-spacerun: yes"> </SPAN>No errors are reported on console or in
logs.<SPAN style="mso-spacerun: yes"> </SPAN>No errors are reported in the
Lock Server either.<SPAN style="mso-spacerun: yes"> </SPAN>Everything
appears to be working correctly as the log information for both machines at that
instant are the same, ie, the one that is hung, has the same log messages as the
one that is not hung.<SPAN style="mso-spacerun: yes">

still trying to mount the filesystem, and unmount the filesystem, node two
immediately finishes the mount command and everything is fine with node
two.<SPAN style="mso-spacerun: yes"> </SPAN>However, when trying to mount
node one again, it just hangs and so on.<SPAN style="mso-spacerun: yes">
</SPAN>It is only allowing one node to mount the filesystem at once.<SPAN
style="mso-spacerun: yes"> </SPAN>The configuration files are all the
generic examples given in the documentation with the fencing mechanism as GNBD
(Tried fencing with manual and the same situation exists with that
method.).<SPAN style="mso-spacerun: yes"> </SPAN>I can provide all
configuration files and also give log file information if this problem isn’t
something that experienced GFS users know what the problem may be.<SPAN
