So that is a DLNA server and the options that I suggested are broadly similar and therefore should work. minidlna might be a good place to start, at least to prove that it can work. Roon is for those who want in depth information on albums, artists, etc. and offers a potentially better media browsing experience. I tried it, but decided that for me it was not worth the cost. It may claim audio quality benefits - but a good DLNA client and server can stream bit-accurate audio gaplessly, so I am sceptical regarding any additional audio benefit from Roon. One important point to note is that the media browsing and selection options are heavily determined by the DLNA server application and not by the player or the control point / media broswer (if that is separate). Thus, some DLNA software will only let you see a list of 500 artists as a single long list - whereas others (Twonky Server, for example) allow custom search trees, and indexed searches (such as A, B, C, D or ABC, DEF, GHI as a first menu level) which can make life a lot easier. There really is no substitute for trying different server applications with your own player and your own music library. I use Twonky for FLAC streaming, but not the exact version found from Community Applications. I just happen to have been running mine as a process started up from the "go" file on my Unraid flash drive, and I've been doing it that way for the past 10 years, long before Docker was available as a means of running third party applications under Unraid. I also run another DLNA server called AssetUPnP, but again I run that more or less from the command line, not via Docker.

@Scancell Does the Bluesound Node support DLNA? (the product's web pages are seriously lacking in useful information regarding the network streaming protocols that may be supported, and the manual tells me even less.) If so then take a look at Minidlna or Serviio in Community Applications (install that first as a plugin if you don't have it). Also there you will find Twonky Server which may also work for you. In Community Applications just search for dlna and you should be able to find these. Edit: I also see that the player should be able to read files directly from a Samba share, in which case you may not need any additional software at all to access music files from an Unraid share on your home network. See here... https://support.bluos.net/hc/en-us/articles/360000469948--How-do-I-connect-music-on-my-NAS-PC-or-iTunes-Shared-Music-to-BluOS-

It looks like the cycle of alternate good and bad releases of Windows is continuing... 95 - good 98 - bad 98 SE - good ME - bad XP - good Vista - bad 7 - good 8 - bad 10 - good 11 - ???? Ok, that's a little contrived, but from everything that I hear about it, I am getting the feeling that upgrading to 11 any time soon may not be worth the effort.

You need to set it that way in the Time and Date settings - but you have control over where it goes. I also set up some other devices so they get it from Unraid, but that's just me...

It's often the case that your router may offer a local NTP server. My Unraid server gets it from there, and only the router gets time from outside.

Without more info we can only make wild guesses.

I don't see this. How long does it run for before stopping? If it stops when scanning your library, for example, then that is most likely an issue with one or more of your media files, perhaps invalid meta-data. I have the docker running for weeks at a time without issue, and the only restarts are for version updates.

There is some set up of folders in the docker settings, but the Web page is working just fine for me both for looking at the library and for streaming to some clients... http://[IP_address_of_server]:3689 For what it's worth, I have never used this with iTunes - I probably wouldn't know where to start.

I would be very surprised if USB display adapters are generally supported by BIOS or by unRAID, since they often seem to have very specific drivers. One option that is PCIe x1 and full-height is this, but it's not cheap and perhaps it is overkill for your needs... https://www.asus.com/uk/Motherboards-Components/Graphics-Cards/All-series/GT710-4H-SL-2GD5/ https://www.ebuyer.com/982815-asus-geforce-gt-710-2gb-4-x-hdmi-graphics-card-gt710-4h-sl-2gd5 https://www.newegg.com/asus-geforce-gt-710-gt710-4h-sl-2gd5/p/N82E16814126433

Just a hunch - could it be a fan failure warning? Either a slow fan, an fan not plugged in, or an incorrect BIOS setting for fan monitoring?

You're welcome. I use this on both my servers to help keep an eye on things. It's especially helpful whenever I am moving / upgrading drives.

The Disk Location plugin does this on the multi-disk summary display. It also displays the current temperature of each drive, regardless of whether they are spun up or not.

Memory errors are probably the most likely cause of a file corruption. It could be that the file has been corrupted while being transferred, or it could be that another write to the disk has been written to the wrong place due to a memory error. Is there a possibility that your memory is being run at a higher speed than desirable? A long run of Memtest may show errors in such a case. Also, have you looked at the SMART data for your drives (via the Dashboard)? If in doubt, I suggest that you generate a set of Diagnostics (via the Tools page) and post that with your next message.

I agree with @JorgeB - either that or the fact that I have been using H77 successfully for around 7 years in one of my servers is just an illusion...

If you are using powerline modems to extend your network such as those from TP-Link, then the performance can be very dependent on the layout of the mains wiring. In the UK, this method of connecting a network often works quite well for connections between sockets on one floor of a house since they usually share a ring-main circuit. Performance between sockets on different floors is normally quite bad. In mainland Europe and the US, it is common to feed each socket separately from the breaker panel, and this makes it much harder for powerline to give a good performance. I am in the UK, and I use powerline for a couple of connections and 1080p rips from blu-ray are playing OK to Kodi. But from upstairs to downstairs it is completely impossible and I use a 1Gbit wired connection instead.

I just wanted to check... Is this a VM under Unraid, or is this nothing to do with Unraid? If the latter, then this might not be the best place to get answers that are relevant to your use case.

The OP asked if there was a need to kill power (not that he wanted to), and my argument is that it should always be possible for safety reasons. But I would also agree with you that using a smart switch is not the way to do this. It would add a significant point of failure, it would also potentially be difficult or impossible to operate in an emergency unless it also had a mechanical override.

I would argue that for safety reasons you should always have access to the mains outlet or its power switch. There are potential failure scenarios in the UPS or in the server that make this highly desirable. Examples could be UPS battery faults, DC wiring faults around PC power distribution to disk drives (a known issue), accidents with liquids, failures in other equipment connected to the UPS, etc. For mains powered products sold in Europe that I worked in the recent past it was generally required that the user be advised in the product documentation that they must be able to access the mains socket while the product is in use.

As part of the above, I set shares that are almost never accessed to not be exported (so they are not accessible or visible on the local network). Then I configure shares for items such as media that are accessed frequently for reading but rarely for writing to be read only. For both of these I only modify the settings as needed of access or updates on a temporary basis. This prioritises security above convenience, but it minimises the time that a potential rogue device on the network could possibly have access. The only shares that I have enabled for writing are not used for critical data, and only for short term storage. On top of that I have a second backup server, which is powered off and therefore completely inaccessible for more than 99% of the time (that is, any time except when I am updating those backups). I accept that not everyone has the luxury of a second complete backup, but it is vital to have additional backups of critical data on storage which is completely independent of your Unraid server. The same would apply to any other network connected storage system.

The UPS software in Unraid is based on apcupsd, and does not generally need Modbus enabled in order to operate correctly. All that Modbus offers is a much more detailed view on the parameters in the UPS relating to power usage, battery and so on. However, I note that your UPS includes what APC describe as "Basic UPS signalling" and I have seen reports that suggest their may be problems in making this work with the apcupsd software. I have not been able to find out what "Basic UPS signalling" really means, but I suspect it may be a very limited protocol, and perhaps only working with APCs own software provided for these units. I suspect also that the Modbus option is not a feature in your unit. I am sure you already looked, but I could not find other references to this type of UPS on this forum

I understand that you would only buy your batteries locally, but there are probably some battery sellers in Sweden who can help you. I cannot advise about alternative UPS brands to be honest. I have only used APC due to the compatibility. Support for APC is already provided in Unraid and it is normally quite easy to configure. My recommendation would be to find a used APC UPS in Sweden that may need new batteries, but then you could find a local supplier for those. I have zero Swedish language skill, but will Google translate I was able to find this battery supplier, for example... https://www.batteripoolen.se/produkter/industribatterier/standbybatterier

This is not generally true. You only pay such a high price if you buy batteries from the UPS manufacturer. For example, APC batteries for any APC UPS are normally very expensive. But you can generally buy the same batteries from a trusted battery brand much cheaper. (Examples would be Lucas or Yuasa batteries sold in the UK). Then you can buy the same capacity maybe for around 30% of the cost. Many UPS use 12V 7Ah or 12V 9Ah batteries - these are standard sizes from many manufacturers. Also many battery suppliers will list equivalent types for UPS batteries for APC and other UPS makes. Here is an example from a supplier in the UK - https://www.tayna.co.uk/ups-batteries/ Sometime a UPS battery is made of two standard batteries joined together, and it is generally possible to assemble the replacements using the same cables and housing.

I don't know how easy this is from the software point of view, but I agree, it would be a very welcome improvement in the behaviour of the user controlled spin down function.

I am not a Sonos user, but I thought their system would also play from DLNA server software. If so then there's a Docker for minidlna that could be tried. It seems complete overkill to have to add an external processor to server a share to the Sonos system. I run both AssetUPnP and Twonky Media Server, to share my audio library to a range of other DLNA clients, although I have these set up to run directly from the config/go file on the flash drive (the apps are on my cache drive).

@DuzAwe - by all means try the guidance here, but it is perfectly possible that you have a different issue. It would probably benefit you and the OP for you to create a separate thread for your issue so that responses and suggestions do not get mixed.
