It's news to me (in this thread!) that XFS is actually "getting some developer love," which is a pretty crucial factor to considering it relevant. XFS was an SGI creation, and, with: a) the not-scintillating performance of the company, b) the lack of a lot of visible work going into the filesystem, c) the paucity of support by Linux vendors (for a long time, if you told RHAT you were having problems, and were using XFS, the next step would be to park the ticket awaiting your installing a "supported filesystem") it didn't look like XFS was a terribly good bet. Those issues were certainly causing concern a couple of years ago. Faster "raw performance" isn't much good if it comes with a risk of: - Losing data - Losing support from vendors If XFS now *is* getting support from both the development and support perspectives, then the above concerns may have been invalidated. It would be very encouraging, if so. -- output = ("cbbrowne" "@" "gmail.com") Rules of the Evil Overlord #228.
