Notes about Linux filesystems
http://sabi.co.uk/Notes/linuxFS.html
Notes about Linux filesystems. Some of my notes on filesystems. Older references are not quite accurate, because things in kernel 2.6 are quite better than in kernel 2.4 and filesystem maintainers have reacted to older unfavourable benchmarks by tuning their designs. So the references below are ordered by most recent first. And the JFS mailing list archive. And the XFS mailing list archive. Results with btrfs and zfs. BTRFS: The Linux B-tree filesystem. XFS: the filesystem of the future? Warnings: many o...

XFS to ext4 for user storage - why we made the switch - PythonAnywhere News
http://blog.pythonanywhere.com/110
XFS to ext4 for user storage - why we made the switch. Last Tuesday, we changed the filesystem we use to store our users' files over from XFS to ext4fs. This required a much longer maintenance outage than normal - 2 hours instead of our normal 20-30 minutes. This post explains why we made the change, and how we did it. Tl;dr for PythonAnywhere users. Tl;dr for sysadmins. Don't use XFS with quotas on current Ubuntu LTS (or any kernel between 3.11 and 3.17), or you're likely to have long downtime. Are just...
