Allow me to drag the OP's question under a different light... I have a 20TB XFS filesystem with 3000000 files. What is the minimum amount of system RAM I will need to run an xfs_check or xfs_repair or xfs_[tool] on this filesystem, assuming Linux has been put into a low overhead state, and said tool[s] has access to the bulk of the system memory? Is there a formula available so any XFS user can calculate this xfs_[tools] RAM requirement, given FS size X and file count Y? -- Stan _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
