[Unexpected High CPU issues [6.9.2]]

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.

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

[(Version: 6.8.3) Weird "stuck" process (SOLVED)]

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

[Advice Please: Looking to get a UPS]

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

[Mover % bar or information]

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.

[Slow startup since upgrade to 6.7]

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.

[Dynamix - V6 Plugins]

Hi, I'm a relatively new unRAID user, but to monitor my setup I decided to add the Dynamix System Statistics plugin (alongside some others) to ensure my server is running as it should be. Today I saw something a little odd on the Network graph (screenshot attached). As you can see the peaks show values above 200Gb/s. My network is two 1Gbit connections configured as bond for failover, and my internet connection is only 40Mb/10Mb so there is no way that level of network traffic should have been generated.

 

The server is an HP MicroServer Gen8 with 4x SATA HDD (3d,1p), 1xSATA SSD Cache.

 

If you need any more details please ask me but I'm curious how this stat anomaly has happened and would be happy to provide more details if this would help fix a possible problem.

 

Thanks
