If you are going to use drives with 4KB physical sectors you need to avoid filesystems with 1KB blocks.
I'm sure there are many in the silent majority here who don't have the detailed knowledge, or, like me, have let it pass them by since they deal with other matters (such as users and applications), and wonder about one or another implication in that statement. We've seen the example with mkfs or extFS for various block sizes, but what about other file systems? And more to the point for most of us: How can we tell about these things? * What block size the disks are are I suppose all late model disks are 4K :-) * what size the file system blocks are for the file systems in use - Not just extFS but XFS, reiserFS, BtrFS - if the are not 4K what can we do about it? * Some might ask about the other file systems in /proc/filesystems. - Does it matter with tmpfs? What about when it 'overflows' to /tmp? * How can we tell if they are aligned? - if they are not, what can we do about it? Either it matters, and these are the questions that emerge, or it doesn't. Speaking for myself, if this issue had never came up, it wouldn't have mattered to me[1], but I'm sure there are people out there who do care even if they are not sysadmins of a large pool of servers. I have friends who are gamers and fall into that category. [1] Regular readers will recall that since the equipment I play with from the Closet of Anxieties is never leading edge, ultimate performance isn't a burning concern. And professionally, the big IBM, HP etc machines are a separate issue. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
