[lustre-discuss] Recovering data from failed Lustre file system

[Vicker, Darby (JSC-EG311)]

I'd recommend using this command to find all the files that were affected:

lfs find --ost <failed ost index> <lustre mount point> > lost_files.txt

Then run an rsync to copy off the data that is left.  Something like:

rsync --exclude lost_files.txt <lustre mount point> <backup dest>

The storage array crashed and we have had some data loss .
What is the best way to backup the available data from client ?
Scp, rsync from client crash on Lustre client osc read error.
