@Switchblade: I can tell you that I can get myself a lot more speed than you said ( I did posted recently at http://lime-technology.com/forum/index.php?topic=28664.msg255628#msg255628 , maybe worth continue this discussion on that topic as drawz pointed... ), garycase posted below me with similar results... and apparently reading the forum for some time now I have the idea that other users can get similar speeds... however each system is a system... though our nic's should be similar... but there are many other factors... switch, cables, client pc's and software on them, etc... etc... Did you tested any other protocol to compare to smb results? try ftp. If you can't get more from ftp also test what speed you can actually read/write on unraid server itself... again more factors... on the server itself, controller, hdd speed (note that hdd's are a lot slower near the "end" of the hdd, same applicable to the client pc hd, you see...).

Some minutes ago I did got emhttp (on rc16) completely and permanently unresponsive, not allowing any further connections to it, after I did started to download a big file from webgui file browser and then cancelled the download at middle. After that emhttp got completely unresponsive and these lines started showing on syslog: Jul 31 03:42:09 unRAID emhttp: returnFile: sendfile /usr/local/emhttp/mnt/disk1/t10: Broken pipe Jul 31 03:58:16 unRAID emhttp: returnFile: sendfile /usr/local/emhttp/mnt/disk1/t10: Broken pipe Jul 31 04:14:23 unRAID emhttp: returnFile: sendfile /usr/local/emhttp/mnt/disk1/t10: Broken pipe and I ended needing to manually umount filesystems, mdcmd stop and reboot... This may not be of huge importance as most users will probably not download files from webgui file browser... but thought I should report this anyway.

@peter_sm: I can only see normal http requests on your log, not any problem?

I did just tested it and I can't really reproduce any smb slowdown on rc16c with w7 as client, see attached screenshots, showing copy to and from cache drive on unraid server. And I'm using the crap onboard realtek nic (details on my sign) and a very very cheap TP-Link TL-SG1008D switch. P.S. I did double checked speed values with iftop to make sure they match the ones showing on Windows file copy window. P.S.2. Repeating test on XP SP3 as client I can still get ~105MB/s when copying to unraid but only near ~50MB/s copying from unraid, however this is not new and I did always seen this on XP as client. I did searched for that on the past and it seems usual, apparently mostly because XP doesn't have smb2 and thus efficiency is not good for a gigabit network, understandable for XP age, but pity that it didn't got smb2 as update, along with tcp rescale window auto-tuning...

'Secure' only allows you to set read/write or read-only, what you want is 'Private'. If before it did asked you to login even on 'Secure' (probably it would show if no user matched both unraid and client pc) it was still not what you want at all... and any login would have allowed to access these shares.

I see a lot of SMB slowness as well. I don't know if it's a blocker, but for directories with more than 100 entires, it's pretty darn slow - taking several seconds to more than a minute to provide a listing. By comparison NFS is very fast. The only slowdown I can reproduce to list files is for folders with many and large files that haven't been accessed since system booted (i.e. fs not cached) but it is not SMB related at all, just fs thing... if I do an 'ls' on them right after system boot I can see same (and yes I know that there is some script/plugin that lists all files to avoid this, but I just don't feel the need for it until now). Other than that I can't really see any slowdown to list files over SMB even for folders with 1000 files I can open them "in a blink" over smb. Not something at client side (realtime antivirus or something similar)?

I had a similar problem (not sure if same thing though, and it was on an earlier vbox version) with w8 when using it with virtual sata controler, switched to virtual ide controler and no problem.

I'm quoting my own post from last year just to say that with the latest unraid rc16c (with 3.9.6 kernel), and latest vbox v4.2.16, now usb share seems a lot better, I can now get 5MB/s from a pen with usb2 support enabled and 8MB/s with usb2 support disabled... both ways a lot more responsive than before for sure, I can't just understand why it is still faster with usb2 support disabled

Yes, better to fix it but corruption on that smarthistory file is surely not the cause of the problems you are getting...

If you just restart the server after it running for some time do you get the same problem or does it only happens when system cold, i.e. at 1st boot after power up? If this is the case then you may want to try to run memtest asap right at 1st boot. Some time ago I had a defective ram module that did only show errors when cold, right after it warms up a bit it would pass all tests... then I was getting similar problems with OS crashing always on 1st boot. Such temperature triggered problems may sometimes be hard to check... as last resource if you have multiple ram modules you may just try to remove one module at a time and test it. Btw, you may also try a different usb drive...

You are lucky there in the UK with the "heatwave", last week with it we did hit 42ºC here in Lisbon, fortunately at night it did go down to acceptable values... and with all closed during day I was able to keep max 30ºC inside without AC surely no problem with my unraid server but it is (yet) a very small server... and green hdd's, low power cpu, etc...

Apparently no procedure runs it. I did got the idea that he had intentions to to call the file for safe-mode but then changed his mind and the file was left... See: http://lime-technology.com/forum/index.php?topic=27960.msg252072#msg252072

since /home/ dir is not persistent I guess you are maybe copying it's contents from the flash on each boot? (and on the flash all is 777...) you may need to add a line on go file to adjust permissions on every boot.

Syslinux is just a boot loader and doesn't have any function after OS loaded. It may be a bug on syslinux that is triggered by old bios... you may use old syslinux without problems or just try to update it (the one on unraid is apparently 4.03), you can get other versions at: https://www.kernel.org/pub/linux/utils/boot/syslinux/ You just need to get two files (from the compressed file you will download) win32/syslinux.exe and com32/menu/menu.c32 then overwrite the ones with same names on root of your flash and then run make_bootable.bat to "install" that syslinux version. I would just start by trying 4.06 as it is the latest one on 4.x series, you can also try 5.x or 6.x but you also don't need the new features on them anyway... Edit: Also note you may need some extra files for 5.x/6.x, see: http://www.syslinux.org/wiki/index.php/Library_modules

Thank you tobias but I would really like one with good linux support to use with tvheadend.

You should use the 'powerdown' script which calls emhttp to initiate the shutdown. The reason you want to do that is because emhttp will generate all the proper shutdown events that plugin event handlers are possibly waiting for. and this is the included one with 5.x ? /sbin/powerdown #!/bin/bash # # Helper script to gracefully power-down unRAID server. # Works only if webGui is running and listening on port 80. # Access a blank page in case this is first request since startup. /usr/bin/wget -q -O - localhost/update.htm >/dev/null # Have emhttp do all the work as if user clicked 'shutdown' in webGui. /usr/bin/wget -q -O - localhost/update.htm?shutdown=apply >/dev/null so what if the array is running (does it stop it, then do shutdown)? what happens if its doing a parity check? or if webgui isnt listening? and finally, can we make this be called if the user hits the power button (not holding it down). From my experience it is called on stock unraid when I hit power button and yes it seems to gracefully stop array and shutdown properly, if no file is in use/open, else it will wait... exactly as when you stop array from webgui.

Did you found a good card? I would like to get one too, with good support on linux and preferentially with drivers for it included on latest kernels without the need for crap vendor/3rdparty patchs etc...

Probably not worth asking it as most probably rc16b will come very soon seeing the clear results of this pool...

I did voted for "Yes, release -rc16b", there are very important fixes on it, mainly for users still running rc15a... and I guess the most important is they update it ASAP. Also I think it may not be the best thing to do to just release 5.0 final without a public rc first with the changes you added on rc16a... it's ok that a few users (me included) tested it really hard, but still a public rc available for everyone to be able to test it before final I think would be a right thing to do (i.e. make sure the stop array crashes from rc13 are not really back on any system or some unexpected problem that could arise as each system is a system...). You can then look at "transport endpoint not connected" issue with more time.

I can tell you that I have a very good experience with 'Leaseweb' for dedicated servers (I do manage some few servers - used as mirrors to a downloads site - hosted with them, on both NL (for 6 years now) and US datacenters (for 2 years now)), so far without any significant problems, other than a problem on a switch on US datacenter sometime ago - quickly sorted - and one or two very small (quickly sorted) network glitches in years... From my experience their service, mainly in Europe, is very good and with good and fast support... not sure though about their vps's. Also note that a big part of European traffic of Wikipedia, as well as some other big sites, seems handled by them. Did also heard good things about 'Pair', from some friends using it to host relatively large sites, but no experience myself.

I did googled a bit and tested on my tests VM and you can just remount tmpfs to a new size without losing files on it. I did just used: mount -t tmpfs tmpfs /var/log -o size=1G,remount Anyone running more extensive/debug logging may just increase it, no?

Did you checked files open at cache disk? something like: fuser -c /mnt/cache Also if it freezes on sync I guess if you try umount it will probably also freeze on it... at least on the 'problematic' one...

This problem is fixed on rc15a, see: http://lime-technology.com/forum/index.php?topic=28075.0

+1, TL-SG1008D here, very cheap thing and runs really cool both the switch itself and the power adapter (many gigabit switchs for home use like some dlink, netgear run really hot...) but I really don't see needing something better for home use...
