dman75 Posted June 26, 2017 Share Posted June 26, 2017 Hi all Im in the process of building a new unRAID system and Im currently moving data to the new drives. Im copying the data from a Windows 10 box using robocopy to SMB shares on the unRAID server. The copy runs fine, speed is reasonable etc for about an hour, then everything stops and I get errors from robocopy. Cannot connect to unRAID via SMB, but everything looks fine in the web inerface. On further investigation I find that the rootfs is full. I reboot, all shares are fine, everything works great for about an hour of data copying, then poof, same issue. Ive attached a USB to the server directly and copied a large chunk of data using cp (around 3-4 hours worth) and didnt have the same issue, so it certainly got something to do with SMB. Ive just done a large-ish copy and watched my rootfs go from 72M free to 45M free in the space of a few minutes. If I go much further rootfs will fill up and I wont have space to run the diags. Hopefully there is enough data in the diags to find out whats going on. I dont have any dockers or vms running. Cheers Dean tower-diagnostics-20170626-2009.zip Quote Link to comment

Squid Posted June 26, 2017 Share Posted June 26, 2017 And you're going to want to post exactly what you're doing. The destination folder etcSent from my LG-D852 using Tapatalk Quote Link to comment
unevent Posted June 26, 2017 Share Posted June 26, 2017 From Telnet/SSH/Console, enter the command below and attach the fsroot.txt file to a post. This will allow us to see what is taking up the space. du -h / > fsroot.txt Quote Link to comment
dman75 Posted June 26, 2017 Author Share Posted June 26, 2017 I have 1Gb memory, this is a reasonably old QNAP box, meaning it has an Atom 1Ghz processor. It runs fine, albeit a bit slow if I try any docker images. The command Im using to copy is: robocopy M:\Share T:\Share /S /E /W:1 /R:1000 /xo /fft M: is a USB attached to my local PC, T is mapped to \\tower\Media Attached du -hx / (added x as Im sure you dont want a listing of all my /mnt data ) fsroot.txt Quote Link to comment

Squid Posted June 26, 2017 Share Posted June 26, 2017 ^^^ This And, you're right at the edge of what is barely functional for a basic file server in unRaid 6+ Functional minimum I would say is 2G RAM. Either upgrade your RAM, or uninstall all of the plugins, and don't use it for any docker apps. Quote Link to comment
dman75 Posted June 27, 2017 Author Share Posted June 27, 2017 (edited) I found the culprit: -rw------- 1 root root 4.0G Jun 27 09:37 smbXsrv_session_global.tdb Pretty sure that shouldnt get that big TBH, this is probably moot, I will be moving the drives in this system to a new PC this week that will have 32Gb RAM and an SSD for cache, but it would still be interesting to know why and how this is breaking.
