But it should be relatively safe to use it. http://marc.info/?l=ceph-devel&m=131942130322957&w=2 If we hit the 4KB limit of xattrs in ext4 how does it show up in the rbd layer? How does it show up in the fs layer, would the fs still be clean? -martin Am 14.11.2011 14:09, schrieb Tomasz Paszkowski: > what about limit on xattr size ?
