I got this today, but I guess that kind of file is one of the kinds you should NOT hash since it gets changed a lot. Is there an list of common extensions you should exclude?

I think it was connected to the HBA all the time, not sure if I ever tried directly to mobo. Its an Dell H310 6Gbps SAS HBA. Edit: My bad, I tried the drive also on my desktop with an X570 board, same problems there, the drive shut down every minute before I turned off the EPC and power balance.

Model ST20000NM007D Sata, none SED

Hello So this is ether something everyone know about, or very few has experienced, because when I got problems with a brand new Seagate Exos X20 20TB, the information on how to get them to work on an none-hardware-server (as most of us uses at home) was not easy to find, so I put down my experience here, just in case someone else may get the same problems as I did. This does not happen on all configs, and are my experience. It all seems to boil down to if the mobo, HBA, sata-controller supports EPC or not as far as I understand. If you don`t experience any of this things with your setup, no need to do ANYTHING! This information is for them who experience the same as me. My drive is an Model ST20000NM007D sata, none-SED ----------------------------------------- Problem 1: Power This drive does NOT like molex to sata power adapters. While I did get it to work, if connected to an adapter, in Unraid, it spits out a lot of read errors. When connected directly to psu power (sata 15pin power) this does not happen. Same seems to happens with my WD Red 10TB drives. As far as I understand, none of these drives uses the 3.3v, so I don`t get why this happens with converters, but it does. Problem2: Backplane: I tried to use the exos in my Chieftec Backplane CMR-2131, this did not work at all, tried with different bays and an 2nd one as I have 2, same happens. Once again I think this has something to do with power as this backplane, 2*5 1/4" to 3*3.5" bay uses 2 molex as power. My recommendation is not to use this backplane with exos drives, may be the same with other consumer backplanes that uses molex as power. Problem3: Drive shuts down/parks head every minute: This was the hardest one to figure out but I found the answer over at r/datahorder. Enterprise drives have certain features I did not know about when it comes to power balance and the Seagates has a feature called EPC that I`m not sure what does, but as far as I understand it parks the read/write head very often. Real server hardware works with those features, but an desktop/workstation board does not, so for us we need to turn those features off in the drives firmware. (yes, I guess this is over simplified but I don`t know how this really works in a real server, and the post over at r/datahorder recomended to turn both of them off for home-use) Once you know how to turn it off, its not that hard I will tell how to do this on Unraid, but you can also do this from Windows. I assume you download on an windows or linux desktop -First we need to download SeaChestUtilities from Seagate -Unzip the folder and go to Linux-->Non-RAID-->x86_64 -Here we need 2 files: "SeaChest_SMART_x86_64-alpine-linux-musl_static" and "SeaChest_PowerControl_x86_64-alpine-linux-musl_static" -Make an new folder on the Unraid USB, I named it "seagate" and copy the files there (this can be done from unraid with the Dynamix File Manager plugin) -Open an Unraid terminal and we need to edit the "go" file -"sudo nano /boot/config/go" -add the following lines to the end of the file: cp -r /boot/seagate/ /usr/local/sbin/seagate chmod -R +x /usr/local/sbin/seagate This copy the files from the usb to an location on the unraid ram drive and makes the files executeable. Files on the usb cant be executeable. -Reboot Unraid -After reboot, open an terminal and "cd /usr/local/sbin/seagate" You should see the files in here now. -First we need to find the exos drive by running: ./SeaChest_SMART_x86_64-alpine-linux-musl_static --scan -Find the right drive by serial number and take an note of its number "/dev/sgX" -then run the two commands: ./SeaChest_PowerControl_x86_64-alpine-linux-musl_static -d /dev/sgX --powerBalanceFeature disable ./SeaChest_PowerControl_x86_64-alpine-linux-musl_static -d /dev/sgX --EPCfeature disable -This should turn both features off and it should be remembered though reboots. -The following commands can be used to check if EPC is turned off: ./SeaChest_PowerControl_x86_64-alpine-linux-musl_static -d /dev/sgX -i Down under "Features Supported" it should say ETC and nothing next to it, that means its turned off. ------------------------------------ After I plugged it in directly to psu and turned off said features, it been working fine with no random read errors I be doing this if I get more exos drives in the future. (and yes, this took some weeks to figure out for me. Ran a lot of smart tests, even forgot the power thing, connected working drive into molex adapter after moving case and parity got ruined because the read errors so had to rebuild after using correct power connector) (hopefully someone else can explain to me WHY some drives just don't like molex adapters. I also don`t know if this is specific to the X20 drives or all exos drives)

As someone who have used both Synology, Unraid, OSX-Server (when that was its own OS) and OSX-Server after it just became an "app" (before Apple just cut server all together), I dont think the Unraid gui is hard to get at all. True, DSM is nice looking, everything feels like an "app", just like on any smartphone, but the Unraid gui is way more simple and things you need to know is way more "in your face" Yes, what is an setting and what is a tool is a bit messy, but you dont need to be an linux expert to understand the Unraid GUI (Im not) I for one does not want an Unraid gui that looks like an iPad.

Im not sure if this is a bug or not, but I get the "error" "macvlan call traces found" even if I have ipvlan on my docker config

Used Notepad++ to find and replace all 5 instances of "md${d:9}" with "md${d:9}p1" in the script and it looks to work just fine now on 6.12.4 (just need to wait and see when it finishes to make sure it actually worked)

aha! Would that be as simple as adding 2 lines that says "cp *location on usb/file1 /usr/local/sbin" "chmod +x "/usr/local/sbin/*filename*" for each file?

Hello I have some linux executable files (SeaChestUtilities) that I want to put on the usb so I can use them without starting the array, but where on the usb should something like this go?

ops, I forgot that and I have restarted after this Now I have tried to connect the drive directly to MB with an molex to sata power, fingers crossed, no errors past 23min. If this is working now, I think I know what the problem is. I started off having the drive in my Chieftec 2*5.4" to 3*2.5" bay, that bay used 2*4pin molex to power the backplane. For some reason, it looks like enterprise drives does NOT like that power delivery/backplane, even if I made sure EPC and power-control was disabled. My older CoolerMaster PSU in the Unraid box has 5pins on the sata power cables, that should mean 3.3v lines are connected, I wonder if it will work if I use those or if I have to use 3pin sata power/molex adapter for this drives.....need to test. When I figure all this out, I may write a post about this complete story so others in my situation can read my experiences Thanks for the input edit: According to the manual for this drive, it needs only 5v and 12v, so it must be something else with that backplane thise enterprise drives does NOT like.....Since they dont have the middle screws, looks like I need a new case for my unraid box soon.....

Hello I thought I had got this drive to finally work after disabling EPC and power-controll (before that the head parket every minute and the drive shut down randomly), but during preclear it seems to fail because no space left on disk? I dont get what is going on now preclear_disk_ZVT5T2M4_18568.txt ST20000NM007D-3DJ103_ZVT5T2M4-20230914-1022.txt

So this happened -during preclear disk suddenly failed. -tried again but this time with pre-read turned on, after 24hours read failed with errors that Unraid no longer can find the disk. -connected the disk to my w10-pc to check with SeaTools, quick test passed. -Checked with long test, after 10min, the disk just disappears from SeaTools, and from windows, just like it powered off. -Just to be sure if the problem was with my sata/molex power and/or sata cable, I did the same tests, long and short with my Segate Ironwolf 8TB, all test pass and no problems. -Tested with Seatools 2min test the day after, the disk disappears/power off after 10sec Looks like I got another dud after the problems with the Ultrastar

Im giving up soon Got an brand new Segate X20 20TB and as soon as I start to precleare it it starts to throw smart errors and after a while preclear failed The numbers just keep going up when I try to do stuff too. Edit: according to this post on reddit, this is normal for segate disks, Im confused

Good advice 🙂 The store was not the problem, bought from one of the 5 biggest computer stores here in Norway.

I contacted seller and got an rma on it and today I got it refunded First time in years I got a bad disk, but it had to happen sooner or later I guess. Now I look at the Seagate Exos X20 20TB instead. In the specs power disable is not mentioned at all on the sata version. Also looks as a good disk and it is a bit cheaper than the Ultrastar

Then I will try to use my current proxynetwork, just will make it more easy I guess since I use NPM already

Nice The new one does what I missed from the old one, the ability to start/stop the entire folder with one button!

Do the NEED to be on their own network or can I put them all in my proxy network?

Hello I wanted to check here if anyone has any idea what is going on or if I just have been unlucky. I bought an WD Ultrastar 20TB because they are very reasonable prized. I know data center drives can have problems in a pc/home server because of sata-power pin3, but I bought the one with legacy pin3 config, "Legacy Pin 3 config – no Power Disable support" and SE (no self encrypt support, SED) and still I have problemes Unraid cant see the disk at all. I tried the disk on my w10 desktop too, with an molex to sata as I heard this bypass the pin3 problem, and my desktop bios/efi dont see the drive, but windows do, it shows up as an 18TB as expected, but when I try to initialize I get an i/o error. The sata cable I used here is new and I know it works. The molex/sata adapter I used for years with no problems.

Not that I don't trust you, but where was it confirmed? 🙂

Makes sense. So ntfs on an fileio gives more overhead than ntfs on an block device it seems then if the speed test is to be trusted.

So I tried an FileIO disk on my zfs-mirror pool just for fun to check the speed vs just use the pool over smb: FileIO Read 240MB, Write 121MB SMB: Read 229, Write 293 Is the iscsi fileIO overhead that big or is it something else? Also have an single 8TB hdd setup as block storage and there I get the expected speed of Read/Write 135MB All is over an 2.5gbit direct connection.

Have I understood it correctly that znapzend is zfs-replication build into an "easier" syntax and with build in scheduling and stuff?

Well, that makes sense and was the reason I thought too. Some say it's because if arc uses too much ram and it overflows, things will crash, but I thought it has more to do with the casual unraid user may not have a ton of ram.

Why is the zfs-arc limited to 1/8 of ram as default? 🙂
