how about directly reading backtrace, something equivalent to: rados -p cephfs1_data getxattr xxxxxxx.00000000 parent >/tmp/parent ceph-dencoder import /tmp/parent type inode_backtrace_t decode dump_json
Where xxxxxxx is just the hex inode from stat(), right. (I only just realized this :-))
Are there Python bindings for what ceph-dencoder does, or at least a C API? I could shell out to ceph-dencoder but I imagine that won't be too great for performance.
