Our apps server using cluster GFS. The idea is want to upgrade to GFS2. The reason is our vendor backup not support anymore for GFS.
We have some issue with our apps server. Our apps server have large partition that store attachment like pdf, video, document file.
This partition is about 20TB. We need to migrate all this folder and sub-folder on new SAN.
What is the best solution? Currently large partition is from SAN storage.
