Hi, Reading the "Repairing a possibly incomplete xfs_growfs command?" thread this month makes me wonder if there is some type of rough formula or guesstimation cheat sheet to figure out how much memory and swap one would need for an xfs_repair given a file system with many terabytes. Say I have an 8TB LUN that needs an xfs_repair. What would be the rough memory requirements and swap space?
General rule of thumb at the moment is 128MB of RAM/TB of filesystem plus 4MB/million inodes on that filesystem. Barry.
