Re: [SlimDevices: SqueezeCenter] LMS@Raspbian - wake up external USB HD attached to router

I've set up the cifs mount thru Webmin and provided extra information
like server IP and workgroup. Since then everything is working fine.

Re: [SlimDevices: SqueezeCenter] LMS@Raspbian - wake up external USB HD attached to router

I'm not sure disabling spindown is much of an option on recent drives.

In general there are 2 possible strategies:
a) enforce system state: don't let the drive slide into sleep,
b) go stateless: try to reconnect every time you need the drive.

As already said by drmatt, first place to look for solutions are
mount/system options on the Pi and on the router.
If nothing helps, some add-on or changes to the client can be made:
- run (on the server or the client) a script that regularly runs
"touch" on a dummy file, accesses a web page on that drive, etc. Beware
of caches which will try to avoid drive spinup. And perhaps finally link
this keep-alive script to LMS usage via SrvPowerControl plugin.
- switch the client to automounting with a short dismount timeout (less
than the HDD timeout). A mount is expected by the O.S. to take some
time, so it is more of a blocking call. Upon accessing the library,
rather than being swiftly returned  by the O.S., LMS would be
blocked until the OS has something to return.

For a robust system I would recommend the stateless way. With a stateful
system if the drive (or router, or link between hosts) goes away your
client will hang until it is back; useful for a thin-client workstation
but not much else. (Not mentioning the case where the client doesn't
hang, but crashes...)

Have fun, maybe.

You could mount the pi0 on the hub and mount the hub on the HDD...

You may also be able to disable spin down altogether if you plug the HDD
into the pi and send it some ioctls using hdparm or similar.

Not the job of the Pi to wake the HDD, it's the job of whichever device
has it mounted. Any file reference via e.g. NFS or CIFS should cause the
fritzbox to wake the HDD. It may not wake in time of course and the Pi
might timeout the action..

I would connect it to the pi via a powered hub.
