This Just happened to me yesterday: A 90 32GB VM ROOT IMAGES stored in one 3TB RBD/XFS volume. Mounting this volume gave an error, "structure needs cleaning" and won't mount. Ran xfs_check. Ran xfs_repair. Mouted rbd volume, no error. Booted all 90 VM ROOT IMAGES. Have not used EXT4 on OSD's or RBD's.

I initially formatted the image using ext4 as shown in the rbd quick start guide, however I have found several examples across the internet that show rbd being formatted with xfs instead. I was just wondering, if there is was any major known pros or cons when it comes to using xfs instead of ext4 (or vise versa) for the rbd filesystem.
