Hi, Not an unRAID expert, but recently I have noticed that my server seems to be serving data a little slower than normal (actually noticed poor Plex server performance mostly), and I think this stems from something a little odd happening with a process always consuming CPU time which I do not expect. This is taken from the processes list in Settings: root 3964 63.7 0.7 1153420 121572 ? Ssl Sep20 1638:55 /usr/local/sbin/shfs /mnt/user -disks 15 -o noatime,allow_other -o remember=0 I have at this point stopped all of my dockers, and removed any plugins I do not need, and the server has been rebooted relatively recently (2 days ago). Is anyone able to point me in the right direction to get this sorted? My server always used to sit with CPU usage idling "normally" at 5-10% and is now nearer 25% with everything stopped. Diagnostics attached. davidserver-diagnostics-20210922-1440.zip

I've been pointed in the direction of this post from another I created (not realising they were connected due to lack of knowledge). This seems to have been outstanding for a while. I do not have any network bridges configured, but do have dockers running. I have now disabled the NetBIOS under SMB as I have no SMBv1 on the network (It is 2021 now!!).

Thanks. Have posted there to follow for any updates/resolutions on that thread.

Hi, I hope you can help me and hope I am asking this question right. I am running unRAID on an HP MicroServer Gen8 with Xeon E3-1220 V2, 4x SATA disks, and 1x SSD (cache). I have noticed in the last 24 hours that my CPU usage has gone up from the normal baseline to a higher baseline (graph from system stats plugin): I am not a linux expert, but instead of just rebooting to clear it I thought it may be a good idea to ask why this has happened, so looked at the processes list and noticed the following: root 4071 12.7 0.3 1160308 54532 ? Ssl 2020 2502:38 /usr/local/sbin/shfs /mnt/user -disks 15 2048000000 -o noatime,allow_other -o remember=0 root 4168 6.5 0.0 2512 100 ? R 2020 1297:54 /usr/sbin/wsdd One process constantly at 12.7% CPU and the other at 6.5% CPU. I am unclear what these are or why this would have happened, can anyone help? Diagnostics file attached. Thank you David davidserver-diagnostics-20210104-0928.zip

Hi all, I hope I am posting this in the right place. I am about to move house and there is potential for the power supply to be unreliable based on where we are moving to. I am planning on buying and installing a UPS to protect my unRAID server, core switch and router and wireless, however there is one critical requirement I want to make sure I get right: I want to ensure that if the UPS goes into battery operation then after a time (or when the UPS gets low on battery) that the unRAID server does a clean shutdown including stopping all the dockers, etc. Are there specific UPS which will work with unRAID? Has anyone got experience of setting this up and would you recommend something specific? Thank you David

I would really apprecaite seeing some form of progress on the Mover to show how long it is likely to run or a count of files to be moved or something.

Are we talking seconds? minutes?  good point. I think it pauses at that screen for about 2 minutes. not sure how i can tell exactly other than to run a stopwatch whilst watching? Is there a log file I could look at with timestamps? Thanks for the other answer. I had looked but clearly not well enough. David

Hi, Not posted for a while so apologies if I have missed any required information. Since updating my server to version 6.7 I have noticed that it has been much slower to start up than previous versions. I do not do much at the unRAID level on my server and it is a fairly simple setup; 4x SATA HDD and single SSD as cache drive, all in an HP MicroServer Gen8 with Xeon E3-1220 with 16Gb ECC Ram. When I have watched a reboot I notice that it appeart to wait for a long time on the screen below for haveged to load: Is there a reason why this may take an unusually long time to start? Also every time the server starts I have to manually press the Start array button regardless of how the server was shut down meaning none of my dockers start if the server restarts unexpectedly. Any advice or information appreciated. Thank you all. David

I am suffering from this error so if any details are needed ping me and I can test or play with my system. Thanks David

Yes unRAID will format a blank disk (or at least give you the option to). For setting up the easiest option is to use the WebUI to create one or more shares (I have several shares such as "Media", "Personal", "Software" and "Backup" but up to you what to create. If your existing NAS is working the easiest way to copy files is simply to connect to the shares using another client and drag them from one to another. Not necessarily the most efficient but certainly simple. Yes you can create your initial array with as few disks as you like (min is 1) and you can do that without any parity drive. Ensure you plan for your largest drive to be available to become the parity drive.

Not sure if this has already been answered but the tech specs show the PSU in a Dell T410 is a 580w so max power draw on the UK 240v would be about 2.5A therefore a 5A fused lead would be sufficient. I know there have already been several responses, but it sounds to me like your system is quiet like mine (although I acquired an HP MicroServer with a Xeon E3-1220 CPU) and I went through the slow process of migrating from older disks to newer ones. The basic plan was use my second largest HDD as the first installed (this will make sense later) and format it as a single drive in unRAID. Copy across my local network from other systems to free up my next largest (always keeping the larges drive outside of unRAID). Each time a drive was empty I formatted it and added it to unRAID as an additional array drive increasing the capacity. When all data was on the unRAID server array I added the last drive (which was the largest I own) and configured that as the parity drive (see told you it would make sense). I have since failed and replaced drives in the server to gradually to increase capacity but otherwise little has changed. I run Plex and a few other dockers to run my media life on the server and everything is quite stable and simple.

Thank you. I had my doubts but the server was quiet enought to stop everything this morning, the DNS is now 8.8.8.8 and 8.8.4.4 and everything is working at full speed. I really wonder what Sky broke in their DNS resolution but will leave my curiosity alone for now

Where did you change your DNS settings? In the unRAID configuration or at the router?

Shutdown, removed memory stick, put in my Windows 10 desktop. No issues. Backup of USB taken. Reinserted in server and booted again. Took absolutely ages to start, but I assume this was waiting for the docker images to all start or the UI to update once they had.

not sure that's my issue. both unraid from a console session and inside the docker images can resolve DNS and ping without issue.

I updated a few docker images on Thursday which is when I noticed this issue so sure it won't help, but if you can get a network trace while you are doing it then that may?

I've not managed to work this out (I don't have traffic monitoring on my home network) but my theory is that during the process of looking at docker related pages in the unRAID UI a call is going to somewhere on the internet which is timing out before the UI is returned. I am on Sky BB so was looking for correlations. I am currently trying to work out how to start monitoring network traffic (a-la-wireshark) on a network without a managed switch. Can anyone who knows more about unRAID than me comment on whether I am chasing dragons?

I will shut the server down this morning and check.

Are you by chance UK based with Sky broadband? I think the issue may be related to unRAID itself accessing the internet...

Not tried to install a a plugin but if I try to update or check for updates on the plugins the same happens.

This is going to sound really odd, and I have been unable to work out what is going on so hope someone can help me. Firstly I will say that unRAID is (and has been) running really well for me. I have a simple setup which is an HP MicroServer with 4xHDD (3d+1p), 1xSSD (cache) running unRAID 6.3.5. Today when I was starting my periodic updates (docker image updates & plugin updates) the unRAID gui started being really unresponsive. All of the docers run fine, share access is fine but any time I try to load a page in the unRAID GUI which shows anything to do with Docker images it takes AGES for the page to load. Most pages load in <2 seconds, ones with Docker stuff on (e.g. Docker or Dashboard) well over 2 minutes. I rebooted the server with a clean shutdown of each docker image, stop of the array, etc. and all started back up fine (although maybe slower than normal) so thought I would ask the question. I am seeing some odd display of the docker images (missing icons - see screenshot) and have attached a diagnostics in case this helps. Anyone able to point me at what may have started causing this? it is a real pain waiting for the ui to load when checking things. davidserver-diagnostics-20170922-1822.zip

Today I came home from work to find my unRAID server completely unresponsive, and while I get it online again just hoped someone would look over the logs to see if there is an obvious reason why. Things I did to test the server before hard shutdown: 1. Tried to load web admin. No response just spinning browser wait. 2. SSH to server. Got login prompt but after entering password never returned a prompt to enter commands 3. HP iLO connection to console. Got login prompt but after entering password never returned a prompt to enter commands (same as SSH). 4. momentary power button press (through iLO). Saw message on console & SSH warning of shutdown but nothing stopped and the server did not do clean shutdown (waited 15 minutes) 5. disconnected network cables. waited a minute connected one, repeated logon attempts, nothing so tried with other network connection, nothing. 6. Hard power off I saved the first diagnostics after power on but before starting the array but then realised I should probably start the array so have done so in maintenance mode, then stopped, done a clean reboot, started the array in normal mode and then grabbed the diagnostics again. It is about now I wish there was a way to start the array with the disks being mounted but prevent my docker images from starting automatically. Everything seems to have come up ok, but just starting a parity check (not writing changes) to make sure all the disks are OK. If anyone has any suggestions for me to check, fix or otherwise I would appreciate it. David davidserver-diagnostics-20170602-2017.zip davidserver-diagnostics-20170602-2028.zip

Thank you for the advice. I reintroduced the parity drive with no problems (SMART was all clean) and will run the memtest as soon as I can shut the server down for a few days. My Plex users are not going to be happy about that!

Hi, Not sure if my server has an issue or not, and I am not sufficiently skilled in reading the log files to work it out. I have the FCP plugin running, and when I logged in this morning it warned me: As a result this is my post, and here are the diagnostics. I have not suffered any problems with the server, noticed any dockers crashing or anything like that. Thank you in advance davidserver-diagnostics-20170205-0838.zip

Just wanted to say thank you to the respondents on my post. The Parity rebuild has almost completed (7 hours to go) with no issues on the drive as predicted. Thank you
