Switching to XFS solved the problem for me. One thing I might be able to add to the discussion: While this problem manifests without disk crypto, adding dm-crypt to the soup, especially on a computer _without_ hardware AES support, generally makes it *much* worse. I've seen disk accesses, especially fsync()s (per latencytop), take minutes in the worst case under some medium disk load; 5-10 seconds are a norm on light I/O load. I can't see much reason why disk crypto should make it that much slower. But since it's a problem also without crypto, perhaps dm-crypt just somehow makes it worse and more obvious? -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
