OverlayFS stuck mounts #22

Closed toxyl closed 2 years ago

toxyl commented 2 years ago

Sometimes (in the order of several times a day to once every few days) the mount cleanup repeatedly fails with the error:

cleanup worker, close overlay '/etc/ossh/ffs/sandboxes/62.173.60.106/merge-1652635240': unmount: invalid argument

this seems to be related to multiple connections from the same host using different ports

Seemed fixed, but it's not :/ It looks like the problem occurs if a host opens tens of connections at the same time.

On the host system more detailed error messages appear:

kernel: [748305.519446] overlayfs: fs on '/etc/ossh/ffs/defaultfs' does not support file handles, falling back to xino=off.

What I could find about this seems to indicate that this is more of a warning than an error. Therefore the error is now being ignored.
