The best way I would recommend is to disable sleep when the laptop lid closes. You will need to open the “logind.conf” file, ( sudo nano /etc/systemd/logind.conf ) and then will need to change #HandleLidSwitch=suspend to HandleLidSwitch=ignore Remove the # Remember to save and exit. You can follow this article <https://corpit.org/disabling-lid-suspension-in-rocky-linux/> Regards, Suyash On Tue, Mar 26, 2024 at 4:16 AM <matthew@peregrineit.net> wrote:

Hi All,

So I've got a Ceph Reef Cluster (latest version) with a CephFS system set up with a number of directories on it.

On a Laptop (running Rocky Linux (latest version)) I've used fstab to mount a number of those directories - all good, everything works, happy happy joy joy! :-)

However, when the laptop goes into sleep or hibernate mode (ie when I close the lid) and then bring it back out of sleep/hibernate (ie open the lid) the CephFS mounts are "not present". The only way to get them back is to run `mount -a` as either root or as sudo. This, as I'm sure you'll agree, is less than ideal - especially as this is a pilot project for non-admin users (ie they won't have access to the root account or sudo on their own (corporate) laptops).

So, my question to the combined wisdom of the Community is what's the best way to resolve this issue?

I've looked at autofs, and even tried (half-heartedly - it was late, and I wanted to go home :-) ) to get this running, but I'm note sure if this is the best way to resolve things.

All help and advice on this greatly appreciated - thank in advance

Cheers

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.

I think the client should reconnect when it's out of sleep. Could you please share the client logs to check what's happening?
