  1. Thanks, trurl. No, it's unpingable and its address is unknown on the network. I've rebooted it several times, with and without the UnRAID boot USB. Without the UnRAID USB it should boot into QTS as the original DOM is still in place. However, it doesn't – all eight drive lights are red, I'm getting nothing over HDMI and the built-in display is stuck at SYSTEM BOOTING… As it won't boot into either UnRAID or QTS, it's looking very much as if we have a QNAP hardware failure. But I'd welcome any further suggestions. -- Chris
  2. I tried to log in today to my UnRAID 8-bay server based on a QNAP TS-853 Pro which has been running flawlessly for several months. I was unable to find it at its usual IP address even after a reboot. As far as I can make out, the Ethernet port is flashing normally and the connection to my switch is secure. I've tested the UnRAID boot USB in a second machine and it boots apparently correctly into UnRAID with the static IP address I'd allocated. I'd welcome any suggestion on how to go about diagnosing this further. Please let me know if any further details would be useful here. -- Chris
  3. My problem with calibre on UnRAID is that the webGUI is completely intractable when accessed from a phone. While the regular UnRAID webGUI can be zoomed and panned, calibre's simply fails to shift, making it impossible to access necessary parts of the screen. Has anyone found a workaround for this? -- Chris
  4. Good question, @John_M. It's all set out in the UnRAID story. The SSD in question uses RAISE and I did ask the forum earlier whether this made an external TRIM utility redundant but the response seemed to be to go ahead with TRIM anyway. I still have my doubts about whether the combination of btrfs, TRIM and RAISE may not be asking for trouble. I understand that OWC, the manufacturer, is currently investigating this. Meanwhile, I'm running the SSD, now happily formatted as xfs. TRIMmed weekly, uneventfully. -- Chris
  5. I've raised a query with the vendor about this, @JorgeB. I'm continuing to run the cache xfs-formatted with a weekly TRIM. I'll report back here if I find out more. -- Chris
  6. Thanks for that, @JorgeB This was the other error being thrown up. Can we be sure it wasn't the result of a TRIM conflict? -- Chris
  7. Not only is the TRIM utility not useful for btrfs formatted SSDs (because TRIM is built in to btrfs) but it appears to be positively dangerous. My recently destroyed btrfs SSD cache drive was using the UnRAID TRIM utility (on advice from other UnRAID users) and succumbed after a couple of months, turning read-only with the error: cache and super generation don't match, space cache will be invalidated If I'm reading this aright (always a big IF) and the current UnRAID implementation of TRIM is destructive on btrfs-formatted SSDs, shouldn't the utility be updated to detect btrfs, warn the user, and render itself inactive? The good news is that only the btrfs formatting was destroyed. Reformatted as xfs, the SSD lives on. But if I can get confirmation of my assertions here, I'm inclined to return the SSD to btrfs. -- Chris
  8. Thanks for that, @ich777 My jDownloader directory is on a single device, which happens to be the cache drive. I'll investigate deleting the .jar file from the appdata directory and report back. LATER THAT SAME EVENING I seem to be in serious trouble. I tried to get to appdate using krusader but its WebUI is kaput too. So I'm using the krusader console. All I can find in /unraid_shares/appdata/ is syncthing. No sign of any other docker data there. -- Chris
  9. Damn, jDownloader is defeating me again. I got it working when I set the port to one not previously assigned to another docker (always a good idea) and it was running fine. But now VNC is telling me it can't connect to the server and I gather from the logs that I have an invalid or corrupt jdownloader.jar. The only two changes I've made to the config files are to set the port to 18080 and change the local download to mnt/user/jDownloader/ -- Chris
  10. You're spot on, @ich777. The clue was in installation log which was trying to warn me of a port conflict. The default port was already being used by calibre. I've now switched to 18080 and all is well. Many thanks for the valuable lesson. -- Chris
  11. JDownloader has been working marvellously. Until today. Now, when I try to start it I'm seeing: EXECUTION ERROR Server error. I removed the docker and reinstalled it. Same result. Nothing appears to be showing up in the logs. Any advice would be welcome. -- Chris
  12. My Calibre Docker's WebUI now announces itself as "Guacamole Client". I think with previous versions it called itself "Calibre". What can I do to change this? -- Chris
  13. Tagging on here in the hope of responses relevant to this thread: I'm trying to understand UnRAID's FTP service. I notice that there are several FTP dockers available in the Apps Store, although I see from /etc/inetd.conf that UnRAID offers the option to run a choice of two FTP servers (vsftpd and proftpd). What advantages do the dockers offer in this context? -- Chris
  14. Did you take SED any further, @stereobastler? I'm hoping to investigate the possibility of using hdparm to set the password on SED drives, rather than using the BIOS. There's an hdparm parameter, --sanitize-crypto-scramble, that I believe might do the trick, Do you, or anybody else here, know anything about this? -- Chris
  15. @dimes007 Did you take your SED investigation any further? I'm preparing an encryption supplement to the Tested Technology UnRAID story and would welcome any more information. -- Chris
  16. This is a question I've put to memory vendors and never had a satisfactory answer. They just quote the official manufacturer's specs back at me. ===✄=== I have an 8-bay QNAP TS-853 Pro, currently with 4GB of RAM and a Celeron J1900 processor. QNAP and Intel both spec the maximum memory capacity at 8GB. However, it's my understanding that this maximum is derived from the number of memory banks available (2, in this case) and the maximum capacity of a compatible memory module at the time the processor was launched (2013), which was 4GB. Would it be true to say that when 8GB DDR3 SODIMMs became available the maximum became 16GB? I believe that 16GB DDR3 SODIMMs single modules are available too. Do you know if these would be compatible with this QNAP hardware (I'm not using QNAP's QTS operating system)? ===✄=== It's a specific question but I'd like to get to the fundamentals. What exactly is that max RAM spec based on? Is it the case that the number of processor address lines limits the number of banks? And that what limits the size of a bank is down to current manufacturing capability? Anyone? -- Chris
  17. Thanks, @itimpi. I'll follow that through. BTW, I have a Pro licence---I'm not trying to limit my drive count. -- Chris
  18. I've installed UnRAID on a QNAP NAS without opening it up to remove the DOM. I want to ensure that the DOM and its contents remain intact in case I ever want to derepurpose it back to being a QNAP again. The WebUI seems to offer no easy way to hide the DOM from UnRAID so I've marked it as read-only. It occurs to me that I might also mark it as pass-though but pass it through to nothing. Does this make sense? Will this achieve my aim? -- Chris
  19. I've much to learn about dockers, @saarg, lovely things that they are, so thanks for that. Is there any particular objection to my using a custom network as described? It seems to be the logical and recommended approach. -- Chris
  20. How does that work out, @saarg? I'll try this if you think it's a good idea, but I'd expect it still to have the base IP address of the docker, not of the UnRAID NAS. -- Chris
  21. It's great to have calibre running on my UnRAID server. Thanks for that. Makes more sense than installing it on some random LAN client. Or, worse, several of them. I'm running into a problem, though, that exposes my ignorance of dockers. When I try to set up the Content Server it announces that it's running on a network wildly different from my LAN., which knows nothing of I can change the port, of course, but can't seem to find where or how to map the LAN address to my own. Installed on a LAN client, as calibre has always been for me in the past, the address of the Content Server is set to the address of the client. So I'm guessing I need to tweak the container parameters but I can't see how. LATER THAT SAME EVENING UnRAID's docker documentation appears to suggest that this is fixed under Docker Settings by changing host access to custom networks from disabled to enabled. However, my Docker Settings here on UnRAID 6.0.9 rc2 appear to glue this parameter firmly to "disabled". I'm wondering if I stopping the array will unglue this. All suggestions very welcome. LATER STILL (SOLVED) It's there in the docker parameters. To run a Web server inside a docker with the same address of your LAN you need to set the Network Type to Custom. Ha! This gives the docker an address on your LAN (not, as I rather stupidly thought, the same address as your NAS). Now Content Server will take that local LAN address with whatever port you allocate to it inside calibre and your calibre library now becomes accessible to any other client on your LAN. This is by far the easiest way, for example, of loading books onto my Kobo Aura. (I'm leaving this up in case it helps somebody else as this doesn't seem to be crystal clear in the documentation.) -- Chris
  22. I'm puzzled by the notifications I found on my Dashboard this morning: a report that the parity check has concluded successfully, immediately followed by an error message from Parity Check Tuning that the parity check was aborted. (I am assuming that notifications are stacked newest uppermost.) My guess is that Parity Check Tuning is assuming that if it is set to run in increments of (say) three hours, any cessation of the parity check short of that time is "an abort". If this is right, unless the whole parity run mod 3 isn't exactly zero we're always going to see this "abort" notice. Can this be right? Please sanity check the conjecture from a relative newbie. -- Chris
  23. It's for creating comics. An Android app called PicSay. Very easy and useful. I use it quite a bit. -- Chris
  24. OK, I've moved on and taken down the link to that private Tested Technology page about my struggles with the Cosmos (possible title for my autobiography, perhaps?). The real UnRAID story starts here. -- Chris
  25. I'm not sure I see how that improves the security. And what if—as in my case—the array is unencrypted? -- Chris
