[patch adding mkdir if "osd data" or "mon data" dir does not exist] The requirement for the osd data dir to exist beforehand is intentional, and is intended to avoid some operator errors; with the mkdir in your patch, it's all too easy to accidentally use a subdirectory of a relatively small root partition, instead of the big extra disk you thought you were using. If you don't want to use btrfs, don't use it. ext4 or xfs with extended attributes will work just fine. Just mount any filesystem in the "osd data" dir, or pre-create the directory. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
