Hi everyone, I am looking for a PSU that will power many HDDs/SDDs (up to 20). I can buy a PSU with 6 cables, with 4x and 2x SATA connectors but these are higher wattage PSUs that are unnecessarily expensive for my purpose. Trying to avoid IDE -> 4x SATA cables, I wanted to try for my first time SATA expanders. So, I have 2 questions: 1. Is it safe to connect a 4x SATA expander to a 4x SATA cable (thus having 7 drives per cable in total)? 2. Is it better to connect the expander at the 1st or the last connector of the SATA cable. Or is it of no importance? Thanks in advance for your answers....

So I tried various proposed stuff (and was away for a bit, sorry for taking too many days to get back to you after your prompt inputs). What I found out is by disabling docker, the problem was fixed. Additionally, I noticed in the dashboard that docker was using quite a lot of memory, when enabled. More particularly 67% of my 6GBs, which is almost 4GBs. I noticed that in my other unraid machine docker was also using ~4GB. I do not understand why that would be since all my containers were stopped. Maybe the memory is reserved by docker?

Thanks a lot for the input. I will boot normally and when the problem occurs again (I am guessing soon), I will post the diagnostics. I might try that too, afterwards. A plugin might be the problem but I seriously doubt it has something to do with Docker since I am nor running automatically any of the installed plugins.

Hi everyone, I am using unraid v6.11.3. Suddenly (without me having made any significant changes), the user shares have started disappearing and they do not reappear until I reboot. Initially it happened once in a while but it keeps happening more and more often (3 times today). Here is what I tried (having also searched the forum for suggestions): 1. Tried stopping and restarting the array - didn't work 2. Changed Settings > Global Share Settings > Tunable (support Hard Links) to "No" - didn't work 3. I have some Docker Containers but they are not running so I dont think they could be the problem 4. Updated all apps - didn't work 5. Checked the XFS filesystem in all disks EDIT: I just noticed an error in the logs: Could this be the problem? My server has 6GB and I am running cache_dirs (folder caching). I also have a LOT of files in the server. I always had but they have been slowly increasing. Could I have reached a limit where the memory is somehow filled? Any help would be very welcome as my server has been rendered unusable.

Huh, I did not know that. Have you tried them?

I just stumbled upon this this Silverstone "ECS07 - 5-Port SATA Gen3 6Gbps Non-RAID M.2 PCIe storage expansion card". I just wanted to mention it because it seems like a very interesting alternative. If a Mobo has 2 M.2 slots one could easily add 10 SATA ports. If they work as advertised, I would certainly prefer them to HBAs. One big caveat is that the price has not been released yet so I dont know if they cost 50 or 500 euros....

I hate it when people try to help me and I seemingly ignore them. I read your answers but I had to be away for >1 month. When I came back, 1 HDD was dead so I first had to replace it. Now the problem has disappeared for some reason. Thanks for your input and know that i did not ignore your input (at least intentionally)...

I did not notice any such errors in the systems log. Thanks for pointing me to the upcoming changes. I think I will wait for 6.10.3, so as not to bother anyone for no reason, and come back if the problem persists.

I had already done all the above but I did not think to try the private mode. unfortunately, it did not change anything. PS: Just to be sure, I tried a fresh Firefox portable but I get the same results...

Hi, I upgraded from 6.9.2 straight to 6.10.2. I noticed that, after the upgrade, for some reason, the main window content takes a few seconds to load (and meanwhile it shows as in the attached file). This happens in Firefox but not in e.g. chrome. It is a bit annoying but minor, I am just mentioning because I dont think it has been already mentioned.

Hi, I have encountered an error that (from what I managed to find) I have not seen mentioned somewhere else. I was trying to benchmark this controller: MV64460/64461/64462 System Controller, Revision B Marvell Technology Group Ltd. RAID bus controller Type: Add-on Card in PCIe Slot 2 (x1 PCI Express) Current & Maximum Link Speed: 2.5GT/s width x4 (1 GB/s max throughput) Capabilities: storage pm msi pciexpress bus_master cap_list rom Port 1: sdj 8TB Seagate ST8000AS0002 Rev AR17 (Disk 13) Port 2: sdk 2TB Western Digital WD20EARX Rev 51.0AB51 (Disk 7) Port 3: sdl 4TB Western Digital WD40EFRX Rev 82.00A82 (Disk 9) Port 4: sdm 2TB Western Digital WD20EARS Rev 80.00A80 (Disk 3) Port 5: sdn 8TB Seagate ST8000DM004 Rev 0001 (Disk 12) Port 6: sdo 8TB Western Digital WD80EZAZ Rev 83.H0A83 Port 7: sdp 8TB Western Digital WD80EZAZ Rev 83.H0A83(Parity) I should add that according to the manual for the mobo, this slot is suposed to be PCIe v.2 (PCI Express 2.0 x16 Slot (PCIE5 @ x4 mode) which seems different with what Diskspeed is reporting. and I get the following error (the error appears when the "Benchmarking Parity (sdp)" bar reaches 100%).. What could be causing it? container run: I should also mention that i have this controller in the same mobo and it is benchmarked with no problems (although it might also be misreported) : MV64460/64461/64462 System Controller, Revision B Super Micro Computer Inc (Marvell Technology Group Ltd.)

Sorry @Alex R. Berg, somehow I missed your comment (and, again, thank you for your contribution). Your strategy is useful for cases like yours, but for cases like mine, where I cannot foresee which file I will need to use, It is not very helpful. Additionally - and this might be less important - in my windows machine I use Everything for indexing/searching, and cache_dirs works well with it... Still, thanks for sharing your scripts, one additional value for me is that they can help improve my shell scripting....

I actually remember @Joe L., I had one or two very pleasurable interactions with him. I both hope that he is having a good time and also that @Alex R. Berg keeps maintaining cache_dirs

@Alex R. Bergyou have a sincere "thank you" from me. just 2 questions for anyone invloved: The thing is, I think cache_dirs is very important (at least to me). If you have many disks you have to wait a long time for a listing. What do people who do not use it do? Is there an alternative? Why does Joe not still maintain it? Is there an "official" reason i have missed?

Everything has been working fine for me, have fun with your vacation...

Just wanted to mention that this is not the case for me (and I am guessing other people who have the same problem), so I hope this helps the particular user but it is not a general solution

Are we sure the problem is on Unraid? Because it might be on the windows side. Although it would be nice if somehow UnRaid could mitigate it

I also have the same type of problem. - Very often I cannot copy the file as everyone else mentioned - It occurs even if I use a third party copier (TeraCopy) - For a few minutes I cannot remove or overwrite the partially copied file. If I try later, I either get the same error or the partial file can be overwritten - When I am copying/moving many files, it will only happen at the start of the copy. i.e., if the 1st file is copied the error does not occur for the following files. As mentioned before, it might be some changes with how Win treats Samba, but, either way, a solution would be welcome, otherwise UnRaid is rentered practically unusable for us Windows users

Thanks for your response, I though so, I just wanted to double check

Before updating to 6.7.1 I run the update assistant and I get the following: Checking for plugin compatibility Issue Found: dynamix.cache.dirs.plg is not known to Community Applications. Compatibility for this plugin CANNOT be determined and it may cause you issues. I have the latest cache dirs version (2018.12.04). Does anyone have problems with cache dirs and 6.7.1?

Hi, did you find a solution? I have the same problem, sometimes files do not copy with the same error message,,,,,

I am fairly certain that the P11 firmware will work fine (although I do not have the particular card) but also have a look at this link. They mention successfully using P19/P20. Btw, if it helps, I have a Dell H200 crossflashed to LSI9211-8i IT with a P20 ( P20.00.07.00) firmware and it works fine. If I were you I would try P20.00.07.00, since it is anyways made particularly for your card, it is not even crossflashing.

I had removed the cardand put back my original SAS2LP in order to use the array. So I put the H200 back in order to post diagnostics and suddenly it sees the HDDs. I really dont know why, before the original post I reseated it 3-4 times & rebooted, I even changed SAS cables and it did not work. Thanks for your willingness to help me and I am sorry for wasting your time but it was not out of laziness. BTW, how can I see data about my controller through unraid?

Hi everyone, I just received a PERC H200 and followed the instructions in order to flash it to IT mode. I followed the last post: There was no error, I was only instructed to skip step 4 (I did not have to reboot). After everything finished successfully, I booted to unraid but the disks that are connected to the controller are not recognized. I should mention that the green light is flashing so the controller is powering up and that I followed the default action which does not install the controller BIOS. Any advice as to how I should troubleshoot? Also how to check if unraid and/or the MoBo at least see the controller? PS: I am attaching the logs folder from the USB stick I used in order to flash, although i dont know if it is necessary logs.rar

1. I have no VMs. 2. I have already changed my MOBO/CPU/RAM to much better configuration (but the 2 SASLP controllers remain). MSI RD480/AMD Athlon 64 3700+/3GB -> Asrock FM2A88X Pro+/: AMD Athlon™ X4 840 Quad Core @ 3100/8GB 3. These are the results for one of the controllers with the new configuration: There is more bandwidth due to the move from PCI e 1.0 to PCIe 2.x. But still, the bandwidth is not balanced across all disks. The bandwidth usage is maximized for each drive until the last 2-3 drives have very little bandwidth available.
