I have confirmed that the NFS mount parameters used on my Ubuntu server are identical for the Synology NFS share and the Unraid NFS share. I also set Global Share Settings > Tunable to YES and the "ls" command against the unraid share still takes 1m57sec. I tested this several times and all timings are identical. The ls against the Synology share takes less than 5 seconds. There are currently 57,000 files on the share (camera video clips). I also logged directly into the unraid server and ran "ls /mnt/users/blueiris | wc -l". The command ran in less than 5 seconds. So why does this command take almost 2 minutes when ran remotely against an unraid NFS share but under 5 seconds when ran ON the unraid server, and less than 5 seconds when executed against a Synology NFS share with the same number of files? All devices are on my home network which is flat with a single subnet. Please advise.

I'm running unraid on a decent desktop (see attached). The array is primarily used as a target for Hyper Backups from a Synology and as a target for FTP from Blueiris (camera NVR software). I mounted the unraid share to a Ubuntu 20.x server and when I run the "ls -ltr" command it takes multiple minutes to return. There are at least 40,000 files on the share. I would understand this but the same command from the same Ubuntu server with an NFS share mounted from my Synology device (with the same file count) returns in seconds. Blueiris FTP's captured video clips to BOTH unraid and a Synology share. On the Ubuntu server, when I launch the "ls" command against the unraid share I see my CPU maxing out at about 27%. The share in question does not currently have cache turned on (kept it off while seeding the filesystem with the 40k files). It is not exported as SMB. For purposes of this post I ran the commands against each filesystem. The one against the Synology share took 17 seconds. The ls against the unraid share had not completed after 7 minutes so I killed it. According to the Array Devices this share is on disk2, disk4, and disk5. Any ideas where to start?

I'm a recovering Synology user setting up a new Unraid box with a circus of disks pulled from a flaky Synology DS. I have 2 x 500G M2 disks on the board, and the following spinning SATA disks: 1 x 2TB 1 x 4TB 1 x 5TB 2 x 6TB 1 x 8TB Does anyone have any config suggestions for these disks for best performance for simple NFS/CIFS file usage? Your opinions are appreciated. Thanks!

Thanks!

Hello, Looking through the options to download and install I don't see any guides for guys using Ubuntu desktop. I dumped all my Microsoft Winders installs a year ago and haven't looked back. How do you recommend downloading and installing Unraid using Ubuntu 20.x desktop? Thanks.

I have no problem with noise. If it's too loud then I can put it in the basement where I am already running two DL380 G6 servers. What kind of price range are the Supermicro rack mount servers?

You have some pretty nice stuff in your signature. I have never built a Super Micro system, how much different are they than the standard offerings they have at the local Microcenter? My bad experiences with dockers on Unraid, again my own fault, led me to decide to let the Unraid do just NAS stuff. Although I have quite a mix of Ubuntu instances on my VMware server (Kloudspeaker, SABnzbd, Spotweb, Owncloud, Emby and experimenting with an LDAP instance), I really didn't want to put too much important stuff on a single box. I actually run a Pfsense install on another DL380 G6 by itself. I'm assuming that running any of the above apps as dockers on Unraid with a robust Supermicro build would probably speed things up pretty substantially for all apps, given that the storage and network are local to them, and maybe I could retire the DL380.

My current server is in a medium sized tower case in my home office (spare bedroom). I believe I have six drives or whatever the maximum was for the cheapest unraid license (I'm currently out of the house) . I have 16GB of ram in the unraid server. I do have a gigabit Network. I am not running any dockers on the unraid server which is only due to my inability to get the darn things to work. The Emby server is running as a VM on an ESX installation on an HP dl380 G6 with two physical CPUs quad-core hyper-threading and 24 GB of RAM. Hot swappable drives would be nice and I would also consider upgrading my unraid license to more Drive count. I am basically looking for something here that I will not have to maintain for quite some time.

Home use. I'm using about 6 of 15TB of usable storage today. Over 90% is Video storage that I and playback through my home network devices (pc, other streaming devices) , and an Emby internet connected server, backups of LAN connected computers and several ISO images that I occasionally boot from. Also have a home cloud server that mounts unraid shares (NFS) to internet connected file servers. I am mostly concerned about performance within my local area network when playing video. I have a ridiculous fast internet connection so downloading from my server is important too.

I recently came into some money and I would like to build a new Unraid server. My current Unraid server is a hodge podge of disks, memory, etc. Yes, I already did the right thing and put new windows in the house (and bought a few toys) so let's just keep the focus on building the "best" Unraid server that money can buy (or at least around $3k). Performance, maximum capacity, and reliability are focal points. If you were starting over, and had a few grand just burning a hole in your pocket, what disks, cpu, memory, and main board would you build a new Unraid server with? Thanks for your replies.

Is there a guide to downloading and installing the non stable versions? Also, where are the RC's kept... can't find anything in the downloads section. Thanks.

Thanks. I'll read up on the how-to tonight.

Yeah, I'm curious what is causing the memory loss. I understand that shutting down the filesystem is the effect, but what is the cause?

For some reason that I cannot remember, I rebooted the box 4 days ago and did not re-enter the settings. I have just rebooted, entered them, then started the array. Was there anything in the log that indicated why I was low on memory to begin with?

I'm baaaaack... About 15 minutes ago my Windows desktop lost connection to an unraid share. I logged into my unraid server and found that I was "out of memory". I stopped the array and tried to restart it but got errors telling me to run "fix common problems". When I launched that app it complained that my server was out of memory (duh), and that call traces had been found. I have attached the lines of the syslog file from just before the server ran out of memory. I have not yet actually rebooted the machine and will probably hold off until tomorrow morning in case anyone wants to see anything that might disappear after a reboot.

I ran the sysctl commands that Johnnie.black recommended and also removed the Krusader and Plex dockers that were not in use and have yet to have a problem. A week ago I had to shutdown EVERYTHING as the local power company was running new lines and had to shutdown my entire block. I have not seen a CPU or memory spike since then and also have not re-entered the "sysctl" commands so I will have to conclude that removing the unused dockers seems to have made the trouble go away. For now. Thanks everyone.

Just teasing about the Synology vs. unRAID. If Synology was that great I wouldn't be here now... The hardware is brand-new out-of-the-box so I tend to doubt it is failing this early in it's life cycle, but anything is possible. I did remove the two dockers this morning and cleaned them up with the Community App (don't recall them name and not connected to my home at the moment). I'll bounce the box tonight to make sure everything is clean, then keep it under observation. Thanks.

Just for fun I deleted the two dockers (Krusader and Plex) and ran the CA to clean up the docker remains. Hopefully the new version will be coming out soon or someone can give us a clue what's killing our machines. Sorry to say folks, but I didn't (and still don't) have these problems with my old Synology...

Your recommendation seems to have helped with the RAM issue but this morning it crashed as all CPU's were at 100% and the system started killing processes. I was able to ssh in and run a quick top and saw that load averages were 17,10, and 4 but nothing was running (that I know of). I also noticed some of the top processes running were "docker" and "php", which was odd as I mentioned before I don't have any VM's defined and have 2 dockers defined but neither are running. I have to delete the plex docker (running it on another machine) and I leave Krusader off until I need it. When I logged in I tried to launch diagnostics but the system killed it. I was able to run "poweroff" which took about 5 minutes and after I powered the machine on I ran a new "diagnostics" (attached). Any assistance would be appreciated. Thanks.

I won't hold my breath waiting for the new release, but I did enter the commands you provided. According to the Dashboard Memory is at 7%. I'll keep an eye on it and if it starts climbing I'll consider installing the swap plugin, unless the new version is available first. Thanks again!

Not to go too far off topic, but how soon before 6.4 is GA? Also, how much of a pain is it to switch to a release candidate, then switch back to GA when it is available, or back to 6.3.5?

It seems odd that there is no system swap file to begin with. Can I create one on an SSD drive? Would this "fix" the problem?

Partial crash. System stayed up but shares went offline. I have attached the latest diagnostics file (I ran before doing a clean reboot from the gui). Seems to be a lot of chatter about running out of memory/swap. The only traffic the box should be seeing is CIFS/NFS. Any advice or observations would be appreciated. Please advise if any other files are needed. There are quite a few diagnostics files in /boot/logs. Thanks. unraid1-diagnostics-20170819-1538.zip

I am running unRAID v6.3.5 (permanent license). The PC running unRAID was built about 45 days ago and made it through a 30 day trial license all the way until today with no trouble. A few minutes ago I was using VLC to watch a video (.avi) on my Win2k10 desktop PC that was playing from a mounted unRAID CIFS share when the video started pixelating then hung. VLC crashed trying to read the file. The desktop computer lost access to all unRAID shares. There are about a dozen unRAID shares mounted to the desktop some CIFS, some both CIFS and NFS. The NFS shares are mounted to several different VMware instances of Ubuntu 16.x on a HP DL380 G6 server. At the same time this happened I was gunzipping a large file (300GB+) on an Ubuntu 16.0.4 VM running on the G6. The .gz file was on an unRAID share mounted to the VM (R/W) via NFS. It hung. At the same time, on a different Ubuntu VM on the G6 server, SABNZBD hung while downloading to an unRAID NFS share. Basically all unRAID shares hung to all my machines. There were no dockers running. There are no VM's defined on the unRAID. I was able to ping the unRAID server but I was unable to http or ssh to the server. I unplugged the network cable but there was no effect so I had to power cycle the server. After power cycling I was able to mount shares and everything came back online. While trolling through /var/log/syslog I noticed that it only started at the time of the crash/reboot. There didn't appear to be any previous versions of syslog. I did run "diagnostics" and attached it to this post. Can anyone please advise where I can find older syslogs or some indication that might show what happened here? Thanks! unraid1-diagnostics-20170816-1951.zip

Is the webapp lighter and more responsive than the client? Maybe I was doing it wrong but since I installed it on Ubuntu on a physical server, I launched the Windows client/install process, but immediately did a remote connect to the IP of the Ubuntu server. How do you launch the webapp?
