Xen users - Jun 2011 - Xen with DRBD, mount DRBD device / Filesystem type?

Hi everyone,

 

I´m using Citrix XenServer with DRBD. But something went really wrong, so I
need a fresh Install.My only question is, how can I mount the DRBD
partition? It is /dev/drbd1 , but if I try to mount it, I need to provide
the filesystem type. Does anyone know what I have to do? I only need to copy
some data from it, it doesn’t matter if it will be destroyed. I tried GFS as
filesystem type, but it says unknown. Or is it possible to mount it without
the DRBD device?

 

Thanks

You need to setup DRBD again (at least on one side) so that it uses the 
same backing device as before (ie: /dev/md1). Once the DRBD resource is 
up (cat /proc/drbd -> Primary and UpToDate). This will recreate the 
/dev/drbd1 device which you can then mount as you did before.

If you want more specific help, you will need to provide the details of 
your setup.
