  1. Interesting! Why honestly, why not just use the Add2PSU and a molex connector between the cases?
  2. yeah, I spent a couple of hours to see how to get this done correctly, and even custom ordering the cables, so they are made properly... cost is more than an second PSU. Easier to get an Add2PSU and use a second PSU. Thanks again for the help! Last question: You mention you run a 3U and 2U as a diskshelf, how are you ensure the power on between the two?
  3. I managed to find some, even higher rated 12V to 5V 10A converters, and coincidentally also some chia miners that use the same method to split the power off EPS and PCI-E.
  4. Ah, I get it. In essence I could make an EPS or PCI-E 8pin to a step-down 12V>5V and 12V>3.3V and then to SATA, or just 5V and Molex. However, I seem to be unable to one in Europe.
  5. Could you clarify what you mean by the DC-DC module and that there's already one inside?
  6. I'm starting to run out of space and room in my rack for drives. I currently have an Inter-Tech 4U 4129L with an array of 14 drives (incl. one for parity), plus an nvme, ssd cache and a hdd cache all working quite well with an Zalman ZM750-ARX PSU. The drives are a mix of shucked 8TB WDCs, 16TB Seagate DC and WDC DC drives totally 152TB, and yes, I'm running out of space. I bought the Inter-Tech 4F28 (imgur), as it can hold 28 3.5" plus 6 2.5" drives (two on either side of the drive cages and two side mounted in the rear compartment) without thinking of PSU, but just needing more drive space. I plan to populate it with WDC 16tb or 18tb DC drives, which usually pull operationally 5V/0.5A and 12V/0.57A, but would like to port over my existing drives which based on the drive spec pull 9.2A on 5V and 9.8A on 12V. Yes, I have been reading a lot here, reddit, and many other communities, reached out via DM to a lot of OPs to figure out their set up's, and found that most just only look at the PSU wattage not amps or just plainly ignore amps, staggered spin-ups, max connections on sata cables, and far too many seem to underpower their systems. Personally, I don't need a high-spec'd CPU or motherboard, I currently use a Gigabyte H97-D3H-CF and an Intel i7-4770 with 32gb, which is more than enough for storage and running a few dockers. The controller is a Adaptec 71605 in HBA mode, and I don't see any options in the controller BIOS for staggered spin-up. The short question(s): - How many drives do you have and what's your cabling/PSU? - My Zalman ZM750-ARX delivers 5V rail 22A 120W and 12V rail 62A 744W (80% load would be 5V/17.6A/96W and 12V/49.6A/595W) is it enough? - Should I get a 2nd PSU, just to be safe? - What's the best mounting options for a 2nd PSU considering the case/any regular 1 PSU ATX/4U case? Am I overthinking this? Did my Googling just make the simple decision a lot more complicated?
  7. Here are some pictures of the 4F28. Very promising! Will try to post more pictures in a different thread.
  8. Thanks for the response. This is good info! I actually started to do some test prints and glue tests, and also started to search for eva foam strips. First test prints were promising! However, while doing my research for eva foam, I discovered that one of the case manufacturers actually started producing a 28 vertical bay rack again, and I just ordered one of those. Only downside is that the rack uses 120mm fans instead of 140mm. Try searching for 4u 28 drives, and the case manufacturer pops up on Alibaba and a few sellers on AliExpress. Inter-Tech is selling them under the model 4F28 https://inter-tech.de/en/products/ipc/server-cases/4f28-mining-rack
  9. wow, this is really an elegant solution and just what I have been looking for. Any chance you can share the STLs or upload to Thingiverse? So many questions also, like: - How does the bottom part look like - How much tolerance do you have on the drives - Why not 15 drives instead of 14? - Any vibration issues? - How is the airflow and drive temps? - On the read, I see two squares, are these just there to hold up the mount? - How did you glue/stick/mount them together? - Did you screw the cage to the rack, or is it just sitting there loose?
  10. Thanks for the clarification. Unfortunately, I don't think that the issue here, as there is no script set to run and the option to collapse the tree is greyed out. It's like unassigned devices is "asking me" to run the script, while there shouldn't be a reason for it.
  11. In the last few days, I've noticed drive three is expanded and a lightning is shown next to one of my drives in Unassigned Devices. I don't seem to be able to find any real info about why this is, except it's to execute a script. However, when I do, I get the prompt it's completed, but the lightning doesn't go away. Any ideas?
  12. That is the error: /tmp/user.scripts/tmpScripts/emby_monitoring_spinup/script: line 18: mdcmd: command not found Only difference to your original script, was that I changed it to monitor for Emby rather than Plex.
  13. I'm trying to use this script to spin up the drives to avoid the Emby coverart loading time. However, when I try to run the script, I get the following error: /tmp/user.scripts/tmpScripts/emby_monitoring_spinup/script: line 18: mdcmd: command not found Right now, I'm just running it to test using the CA User Scripts "Run Script" option. Any ideas why it's reporting mdcmd not being found? I did try to run mdcmd status | grep "rdevLastIO.1}=" | cut -d '=' -f 2 | tr -d '\n' from the webterminal and that worked fine.
  14. Just to give an update here: I'm back online! YaY Flashed the USB drive again Copied over super.dat and the drive assignments were found Copied over the Shares folder and got my shares back. Still had to do some configuration, as the shares weren't set up to use cache. Copied over the Plugins folder and got my dockers back. Some of them had broken templates as the xml file in flash\config\plugins\dockerMan\templates-user was lost. Turns out that if you uninstall a docker and leave the image and the reinstall and keep the same paths and ports, it fixes the missing template. I wish I had known this before I delete some of my dockers. Fortunately, the most critical ones were recovered Had to reinstall lots of plugins Had to set up all my settings again I only a few files that where in the process of being copied when I did the hard shutdown, and of course spent my Saturday fixing my mistake Lessons Learned: Don't write scripts after a bottle of wine Test and QA your scripts before using them Backup Backup Backup Unraid works a lot better than I expected!! Thanks for the help here and on Discord!
  15. Looks like only the plugins, shares and super.dat are intact. Reading a lot more instructions, it looks like that you can read out the disk assignments order from super.dat using strings. However, you can also copy super.dat to your new USB config folder (reboot) and then it should load the assignments. Gonna cry myself to sleep and wake up and try this....
  16. What I tried: > Copied the config folder to a backup location > Flashed the USB again and copied the config folder over > Booted up. I get a prompt, but the webinterface does not load, nor does the array start (was set to autostart) and /mnt/ is empty except for /disks/ and /remotes/ > Flashed the USB again, didn't copy over the config folder, webinterface now loads No I don't remember the disk assignments order. I have a partial screenshot of the drives, but none of the names are visible. Nor can I deduce from the screenshot which drive is what as the drives have been filled even more since then. What happens if I start the array again, but with a different drive order? EDIT: Is there a file in config that should have had the order? super.dat seems to have something, but it's not humanly readable.
  17. So I need to know - rather confirm - how badly I messed up, and what I think I need to do, is what I really need to do. Background: I was messing with CA User Scripts to backup a Emby's library.db and delete backup's older than five days using the command find . -type f -mtime +10 -exec rm {} ; .... but as you can see, I forgot to put the path appdata path in. I had webterminal open, no commands worked, not even ls... Unraid webadmin didn't even load anymore.... my heart starting racing, did I just rm -r everything!!! I panicked and did a hard power off on the powersupply. Checked the USB... almost all the files are gone :((( there are a bunch of files in /config... I grabbed a cuppa... read the community posts and wiki and I know I messed up badly... I followed the recommendations to copy off everything, flash the USB again and copy back the /config folder... Unraid boots, but webinterface isn't loading.... and no I didn't make a backup of the USB / flash backup, since I was still in the process of getting my 100TB server set up.... so... how bad is this? bad bad bad... or baaad... I'm thinking of just going to bed and crying... Right now I flashed the USB again and started booting up. I guess, I'm starting fresh... arg... Or give me some hope ppl... Although, I crushed that myself...
