Problem You may get trouble when you remove your ceph source by rm -rf ceph if you used vstart.sh before:

rm -rf ceph
rm: cannot remove ‘ceph/src/dev/osd0/current’: Operation not permitted
rm: cannot remove ‘ceph/src/dev/osd0/snap_1’: Operation not permitted
rm: cannot remove ‘ceph/src/dev/osd0/test_subvol’: Operation not permitted
rm: cannot remove ‘ceph/src/dev/osd0/sync_snap_test’: Operation not permitted
rm: cannot remove ‘ceph/src/dev/osd0/async_snap_test’: Operation not permittedasync

This is because vstart.sh uses btrfs create those subvolumes for osd.spa

Solution
You should first delete those subvolumes before trying to rm those directories. List, delete subvolumes as below:

sudo btrfs subvolume list ${PATH_TO_SOURCE}code

ID 351 gen 291361 top level 5 path eric/workspace/ceph/src/dev/osd0/current
ID 352 gen 291671 top level 5 path eric/workspace/ceph/src/dev/osd0/snap_1
ID 353 gen 291361 top level 5 path eric/workspace/ceph/src/dev/osd0/test_subvol
ID 354 gen 291671 top level 5 path eric/workspace/ceph/src/dev/osd0/sync_snap_test ID 355 gen 291671 top level 5 path eric/workspace/ceph/src/dev/osd0/async_snap_testrem

sudo btrfs subvolume delete /home/eric/workspace/ceph/src/dev/osd0/*get
