May 11, 201511 yr My array is running unRAID 5.0.4 and it got a lot slower very recently. Any ideas how I could find the reason for this issue? Thanks for your help!
May 11, 201511 yr The first step would be to post a syslog to see if anyone can spot anything that needs looking at.
May 11, 201511 yr @luksak: can you describe what you mean by that? What operations were slower and how did you measure it? (Parity check, disk rebuild, file copy/move, etc)
May 11, 201511 yr Author I am sorry for the poor report. Attached you can find my syslog. @ysss: I am accessing my array using AFP, which is slow in general. But very recently it got that much slower that the Mac OSX Finder crashes listing folder with a lot of files and VLC is unable to play any videos. I just found out that the memory is full. I tried using top to find out what uses a lot of memory but without success. Any idea how to do this? syslog.txt.zip
May 11, 201511 yr Probably unrelated, but your syslog has this: May 9 13:23:05 Tower kernel: FAT-fs (sdg1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck. Put your flash in your PC and let it checkdisk. I think on apple it uses something called Disk Utility. As for your speed, possibly your network connection has degraded to 100mb. From unRAID command line, what do you get with ethtool eth0 ? What do you mean memory is full? Linux will normally use up any free memory for i/o buffers. It is not unusual for memory to be full. See Linux Ate My RAM
May 11, 201511 yr The syslog shows that there is definitely some sort of corruption/failure on the USB stick so follow the suggestions for fixing this. If it cannot be fixed then the other possibility is that the USB stick is failing and you will need to follow the procedure for getting a new USB stick and contacting LimeTech to get your license transferred to it.
May 11, 201511 yr Author @trurl: Here is the result of ethtool eth0 : Settings for eth0: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: Symmetric Receive-only Advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: Twisted Pair PHYAD: 0 Transceiver: internal Auto-negotiation: on MDI-X: Unknown Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000033 (51) Link detected: yes omg, you were right about the ram. everything's fine. I' ll try to repair the memory stick an get back to you. Thanks!
May 11, 201511 yr Author I am still getting this one ofter repair: May 12 01:33:00 Tower kernel: FAT-fs (sdg1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck. Is my USB drive broken? How did my network connection get degarded to 100MB/s?

Is my USB drive broken? How did my network connection get degarded to 100MB/s? Not sure about your USB drive. I have seen that in the log when there was nothing wrong. Your previous log did have a lot of other things in it about your USB drive. Maybe post a new log and we can see if it is still throwing errors. GB ethernet can be very sensitive to cable and plug problems. The first thing I would try is unplugging and replugging the cable at both ends.
May 14, 201511 yr Author Now my network is back up at 1GB. I guess a cable was the problem: Settings for eth0: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: Symmetric Receive-only Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: Twisted Pair PHYAD: 0 Transceiver: internal Auto-negotiation: on MDI-X: Unknown Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000033 (51) Link detected: yes But I am still facing the same problem. I am unable to play a 1080p mp4. I attached a new syslog. syslog2.txt.zip
May 14, 201511 yr But I am still facing the same problem. I am unable to play a 1080p mp4. I attached a new syslog. That syslog seems to be one taken just after a reboot - I assume it does not cover you trying to play a mp4? When you say you cannot play a mp4 are you talking about a specific mp4 file, or any mp4 file? If it is any mp4 file then I would think the problem was at the player end, not the unRAID one.
May 14, 201511 yr Author No, this syslog includes trying to view several mp4s. I am trying to access my array from my Mac. I am used to very slow directory listings as a lot of people using AFP with unRAID. But since a few weeks the directory listing got so slow that Finder crashes and VLC is unable to play 1080p files. I doubt that the issue is with Finder or VLC...
May 15, 201511 yr It is a selection when booting. The boot options appear in the screen when booting.
May 15, 201511 yr How do I enable safe mode? I couldn't find anything about it... SAFE mode is on the boot menu before unRAID starts.
May 15, 201511 yr How do I enable safe mode? I couldn't find anything about it... It is one of the options on the unRAID boot menu. If you have a monitor+keyboard on your unRAID system then you can select it when booting the system. If you run your unRAID system headless, then you can edit the file syslinux/syslinux.cfg that controls the boot menu on the USB drive and move the 'default' entry to the section for Safe boot. If you then reboot the server you will be in Safe mode.
May 15, 201511 yr Few things to try... 1. Have you tried copying said 1080p movie from one unraid disk to another? mc (midnight commander) can show the copy speed. 2. Have you tried a different protocol? Samba? Does it exhibit the same problems? 3. What kind of switch do you have? Tried switching ports? If it's manageable, check the log on the switch? 4. Do you have other computers to test with? Does the problem show up on all clients?
May 31, 201511 yr Author Sorry to reply that late... I didn't have time to look into this issue further. Yes, I am running unRAID headless. I don't understand where I should move 'default'. Here is what my syslinux.cfg looks like: default menu.c32 menu title Lime Technology LLC prompt 0 timeout 50 label unRAID OS menu default kernel bzimage append initrd=bzroot label Memtest86+ kernel memtest

May 31, 201511 yr Author I guess I will wait for unRAID 6 to be released and see if the problems persist...
June 16, 201511 yr Author Well, upgrading to 6.0 solved the issue. Now even 4k mp4s play without any problems...
