Hello,
I am trying to recover data from a RAID 5 configuration with vinum/gvinum and notice some integrity problems on the system I've been asked to 'fix'.
Here are outputs telling me the status of the system.
Rather than get the entire system operational, the goal is to retrieve data from disk, so my intent would be to try and get the offset and length and use the dd command to grab the desired data, not concerning myself with the swap partitions, etc. The offset and length are not shown with the list command nor the vinum printconfig command.
Any thoughts on how to approach this with the problems shown above?
Thank you,
Scott
