I would also highly recommend mpifileutils. Not only is very high performing but it is also lustre aware, allowing you to copy all non-lustre extended attributes (e.g. those associated with FACL’s) but honor the striping/PFL settings on the new lustre file system. If you use another tool, be very careful with copying extended attributes, especially if your PFL/stripe settings are different between the two filesystems.

I'd recommend mpifileutils and the parallel dsync if they are two separate file systems. ________________________________________ From: lustre-discuss <[email protected]> on behalf of Ihsan Ur Rahman via lustre-discuss <[email protected]> Sent: Wednesday, October 15, 2025 11:05 To: [email protected] Subject: [lustre-discuss] Copying the data from one lustre to another lustre Hello Lustre Community, We have two lustre file systems.
