Re: Linux Laptop Losing CephFS mounts on Sleep/Hibernate

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



So the client session was dropped when the laptop went into sleep mode,
maybe what could've happened is that since the client is silent; it failed
to renew its caps in time and hit `session_autoclose` (defaults to 300
secs) and thus got evicted. As Kotresh mentioned, client logs would reveal
better insights.
