[Lustre-discuss] MDT backup procedure

[Daniel Kulinski]

As we move forward with our lustre testing I am wondering about MDT backup.


 

Is it feasible to unmount the MDT, create an image of it and remount it
after the backup.  Of course this wouldn't happen but nightly.

 

>From what I can identify, in the case of an MDT failure we would have to do
the following:

 

Restore from the last backup.

Run an lfsck across the filesystem.

 

Am I missing anything else at this point?  We will also be doing file level
backups of the filesystem as a whole but we are looking for quick ways to
recover from an MDT failure.

 

Thanks,

  Dan Kulinski
