>> Apparently the Synology shell is something of a virtualization layer on top of the actual OS.
Yes, sort of. The user-interface for Synology DSM runs on linux. It's not a virtualization layer as such, but just a user-interface on top of regular linux. In the case of my Storage Manager, it does provide a bit more insight than smartctl, but that's probably because Synology developed other tools to manage the raid array. They call it "SHR - Synology Hybrid Raid", which is like regular RAID, but allows different types of disk, and volumes can grow/shrink. >> Do note that RAID 5 is a three disk configuration, so one of your disks must function as a spare. Does SSM tell you which one is which, i.e. which one is the spare? Actually that's not correct. Raid-5 has one-disk redundancy, but there is no concept of a "spare". Think of it like this: There are 4 disks in the array, all are equal to each other, and when a file is written to the array, the parity is calculated, and stored alongside the file, and it's distributed across disks. Then, if any one of the four disks fails, a new disk is inserted, and all the missing files are reconstructed, one by one, based on the parity. >>verify this behaviour with the Duet Now I can't because I no longer have a Duet. I had one for years, but recently sold both on ebay. I have replaced the Duet with my Raspberry Pi. I can say for sure that this issue does NOT exist with the SqueezeLite running on piCorePlayer on the Raspberry Pi 3B+. I tested it again yesterday, and it ran all day with not a single hiccup. >>That implies that the problem is on the client side, not the server. Yes I agree. I also used the Synology LMS for years with the Duet, and also never saw an issue like this. That's why I presumed that this is a windows-specific client-side issue. I also re-ran tests on BOTH my windows machines separately, and both have the same problem with audio dropouts, and the exact same behavior too. 1. Dell XPS-13, Core i7 6th gen, 16GB memory, windows home. 2. Asrock Mini ITX, Core i7-8700K, 16GB memory, windows pro. For both machines, the behavior is the same: * Interruptions happen every 5, 10, 15 or 20 minutes, almost exactly these time-intervals * The interruption always lasts for 30 seconds, and then resumes. >>Do you have active drive mappings to the Synology on the Windows client? Yes, the Synology is running Samba, and both windows systems have drive-mappings to the Synology over Samba. I don't see how this could affect the behavior of the SqueezeLite, because it doesn't talk to the Synology over Samba. >> If after some time (probably about 5 minutes or so) you see a red X appear over the mapped drive Good suggestion, but I confirmed that there is no network outage. I know that when you unplug the ethernet cable, or reboot the NAS, I would see those "red X" showing that the drive-mapping had become disconnected, and when the connection is restored, you only need to click on the drive-mapping, to reactivate it. That feature works as expected, but in this case, there is no network outage. That is, when SqueezeLite loses audio, I can immediately navigate to samba shares, and the network connectivity continues normally. I have examined both windows and synology systems during the outage, but everything is normal. Thus we can say that the SqueezeLite client is the only cause of the outage. But since it's hard to reproduce on another Windows system, we still don't know that for sure. There could be some weird routing issue with my LAN on which these 2 machines sit, but I don't know what that could be. It could be some weird Windows thing but what? The right way to fix this, is to debug it on my machine. I'm not set up with Visual Studio, but I could set it up and do a debug session, if we exhaust the basic options. Separately, I'll reply to ralphy and test the new build he put up.
