Sorry, but why is that? And do you mean read performance, write performance or both? And is that a factor of the type of storage (e.g. spinning disk vs. SSD)? > In addition for the root file system, you really do want to leave the > default at 5% so that root can write to critical file systems. Sure, I didn't suggest eliminating the reservation, just reducing it. Or is there some reason that root would need at least 5% (as opposed to 1% or 2%) of disk available to write to that I'm missing? > And since the vast majority of Ubuntu users are using a single root > file system, that implies that the for the vast majority of file > systems created by Ubuntu, the default is in fact appropriate. While that may be true of Ubuntu on the client (desktop, laptop, tablet, phone, etc.); I'm not sure it's true of server and cloud? -- James -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1340448 Title: 5% reservation for root is inappropriate for large disks/arrays To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/e2fsprogs/+bug/1340448/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
