  1. 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
  2. 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
  3. 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
  4. 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
  5. 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 dete
  6. 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
  7. 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
  8. 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
  9. 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
  10. 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
  11. 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
  12. 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
  13. @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
  14. 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 b
  15. Thanks, @itimpi. I'll follow that through. BTW, I have a Pro licence---I'm not trying to limit my drive count. -- Chris
