*It seems that 45085cbf-da10-4852-9d85-754707d20a92 was
disconnected at 12:36:49 from vdsm.log, just before this
ConnectStorageServerVDSCommand() in engine.log at 12:36:58. What
does that mean? Did it connect the Storage server after the VDSM
disconnected the StorageServer in a very short time interval. **

I suppose something went wrong in the flow of deactivating the SD
and then detach it<br>
<br>
As soon as I saw the red mark showing the down status of the
Export domain I placed in Maint, I clicked the "detach" button and
kaboom!<br>
<br>
IMO it took the "right time" before the mark went red and SD was
marked as "Maintenance" so I didn't raise any suspect, but
immediately after it failed to detach and was NOT mounted on the
node. <br>
<br>
Did the GUI say SD was down while it wasn't yet?<br>
<br>
After I remounted the Export SD on the node by hand I was able to
detach the Export Domain using the GUI.<br>
<br>
It looks like some sort of "asynchronous" execution of commands on
the node isn't it?<br>
<br>
Thanks and bye<br>
