MDT needs to be formatted with {{--mkfsoptions="-O extents"}}. This is not a normal configuration, but has been seen in the field
-
6163
Description
Short symlinks on MDT filesystems formatted with the "extents" feature appear to be created with the EXT4_EXTENTS_FL in osd-ldiskfs, but that shouldn't be happening. e2fsck considers this a corruption and deletes the symlink.
While we have never formatted MDT filesystems with "extents" enabled, some users have done this, or enabled it after formatting, and the MDS should not corrupt such filesystems.
