chickensoup Posted March 22, 2015 Share Posted March 22, 2015 Hey guys, For the last few months I've had some intermittent issues with slow copying to my unRAID box. At first I suspected my cache drive, then a particular array drive but I'm still having performance issues. I have removed my cache drive and writing directly to the array, copies level out at about 2mb/sec. Apart from the above, I've also tried upgrading from 5.0.6 to 6.0b14b and while again I thought this fixed the issue- it hasn't. No dropped packets.. root@Tower:~# ifconfig eth0 eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.1.5 netmask 255.255.255.0 broadcast 192.168.1.255 ether 1c:6f:65:80:5f:a4 txqueuelen 1000 (Ethernet) RX packets 2759309 bytes 1519961540 (1.4 GiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 4346454 bytes 6418082330 (5.9 GiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 root@Tower:~# Attached: I did notice a SMART attribute (188) Command Timeout when looking at my parity drive. Since this only seems to be affecting writes and doesn't appear to be specific to any particular disk. Could it be my parity drive on it's way out? It doesn't seem to be limited to a specific machine or operating system as copies affect my Windows 7 PC, Windows 8 PC and Linux Mint VM (hosted on Win7 PC) when writing to the unRAID PC. These are all connected to the same switch however when copying between the Windows PC's I get consistently over 100MB/Sec. syslog22-3-15.txt Quote Link to comment
Duppie Posted April 10, 2015 Share Posted April 10, 2015 Same here :-( and I cannot pinpoint the fault. From Unraid (read) ->>> Synology I get 40MB/sec from Synology >>>> Unraid (write) I get 2MB/sec. The Unraid and Synology box is connected via a 5 x 1G port Netgear switch Duppie Quote Link to comment
