Then one of these flags was assigned a meaning, causing things to break. Running e2fsck v1.45.4 or later on the filesystem should fix this by clearing the casefold flag. Can you try that? I'm not sure there's anything else to do here, unless we were to make the kernel ignore unexpected flags. Ted, have you considered that? And it is intentional that e2fsck ignores unknown flags? -- You are receiving this mail because: You are watching the assignee of the bug.
