| Summary | 0009297: With an OverlayFS that has Btrfs as the upper layer, removal of directories silently fails |
|---|
| Description | When an OverlayFS is mounted with a Btrfs filesystem as the upper layer and the user attempts to remove a directory in the overlay that exists only in the lower filesystem, the directory whiteout character device is not created in the upper filesystem, nor does the directory appear to be removed in the overlay.
This issue is reproducible regardless of the filesystem type of the lower filesystem, and does not reproduce when other filesystem types such as ext4 are used as the upper filesystem. |
|---|
| Steps To Reproduce | The attached script will reliably reproduce the issue. |
|---|
| Additional Information | This was tested on EL7 kernels, Fedora kernels, and mainline kernels (tested with CentOS 7, Fedora, and Arch). |
