My thoughts on this are roughly: * 2.7T isn't really big ext3,xfs,jfs,etc. should all be fine * We've run XFS alot, but still, it's a lot less mainstream than ext3 * Ext4 is still a tech preview in 5.4 * We have alot of data on Lustre-style ext3 (in the range 4-8T), no issues Boils down to: Use what you're comfortable with (XFS is typically faster for us but ext3 certainly won't break down at this scale). /Peter > As for XFS I have read that a UPS is necessary and this is not a problem > since these machines are already connected to a UPS (and that UPS has a > backup as well). > > Any help appreciated, thanks, > > Khusro
