P.S. What sort of flex_bg size are you using? EXT4-fs: not enough memory for 8198 flex groups EXT4-fs: unable to initialize flex_bg meta info! Modern e2fsprogs default to using 16 block groups per flex_bg, which means 8198 flex groups is a little over 16 TB --- which the mainline e2fsprogs doesn't support yet. You wouldn't be using a smaller flex_bg size for some reason, are you? If so, can you say something about why? I've been actually thinking that we might want to bump up the flex_bg size slight more, but it appears you're using something smaller; was this deliberate. - Ted -- 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
