Thank you, I forgot to close of the router! done now...

Ok, so ftp disabled, rebooted, checked disabled but still loads of attempted logins? help anyone please?

ok... thanks for the info, I will investigate VPN, if anyone has some novice pointers I would appreciate it! Cheers All

Thanks jonathanm, do you mean not putting myself in the position by not having my unRAID server connected to the outside world?

Thanks for all your input guys, I need to have a good look into making this as secure as possible.... I am using the ProFTPD Plugin and it is behind a DD-WRT Router so I should be able to work something out! Thanks again....

Hi, yes I access the unRAID whilst out and about

The first point is that you want the Min Free space setting for the cache drive under Settings->Global Share settings share to be larger than any individual file you are copying (e.g. At least 4GB with the quoted example). This is because once unRAID has selected a file to start writing it it does not later switch that file to another drive if there is not enough space for the file. When the free space on the cache drive falls below the Min Free space value any subsequent files are written directly to the array (albeit at a slower speed) bypassing the cache. Perfect! that is what I hoped for :-)

Hi, I understand the single file size limit put on the cache drive but what happens for example if I am copying for example 100 4GB files to my server with a 250GB Cache drive when it fills up? what happens to the other 150GB does it then start writing to the disks directly? Many Thanks

Probably network related, try different cable/switch. Many Thanks, it was the "New" Switch! bye bye Netgear!

Ok, so I am able to write to server at over 100mbps but can only read at 9-11mbps? I have changed the cache disk, also tried an IBM server Gigabit LAN card (slight improvement to 13mbps) any ideas as to why my read speed is so slow? Many Thanks

Just an update, I have tested fastcopy as recommended by many sites & I get 105mbps when writing to the cache disk which is great but also with this copier I am only getting 1mbps? I notice that when writing the disk activity light is almost on all the time as expected but when verifying I barely see a flicker? something is bottlenecking up! any ideas? I have attached the diagnostics file Many Thanks unraidserver-diagnostics-20160421-0110.zip

Thanks for all your replies, I bit the bullet & bought the upgrade and now getting solid 90mbps+ constant write speed which is great, the issue I have now is the verification speed using Teracopy from Windows as it takes approx 3-4 minutes to verify 2GB! Anyone else experience this? is Teracopy a problem? is there an alternative file copy program that verifies? Thanks again for everyones support...

Have not tried Turbo Write as I do not think it is the path I want to go down... I am getting 90mbps reading from the unRAID server... This looks as if everything is working ok (My Network) it is just down to the parity write... I will have to consider upgrading my licence for the cache disk I suppose

you will only need to upgrade your license if adding the cache drive takes you over the attached devices limit for your current license. It would do... by one

I will work out how to post diagnostics but after reading it would seem that a cache drive would be the answer (I have a spare 120GB SSD lying around) its a bit crap that I have to upgrade my licence though just to get acceptable speeds...

Hi, I have been struggling to get good speeds from my unRAID server and have some comparisons from another machine in the same network. I have just replaced all the cables to CAT6, Replaced the Switch (I have tried 3, DLINK, NETGEAR & TPLINK) From my Desktop machine to my G1610T 8GBRAM unRAID server with Western Digital/Samsung/Seagate 2TB Disks I get a transfer rate of 32MBPS after the write to memory boost of 80MBPS but if I write to my Windows 7 HP G1610T Gen8 Microserver 8GB (Same CPU, Same RAM & Same Disks) I get a constant 95MBPS? what can be slowing the unRAID server down so much? I have been struggling with this for quite some time and cannot currently see the point to having an unRAID server when Windows 7 seems to be so much faster? I understand there are hardware differences so do I need to change my network card in the unRAID server? Please understand this is not a dig at unRAID because despite all this I love it, I just need faster transfer speeds... Many Thanks

That's great news, Many thanks for your hard work

Any updates on this? sorry if it appears rude? I have no idea what is entailed! is it a quick job for someone knowledgeable? Many thanks :-)

Hi, I have just trialled the software using 2 data disks and 1 parity, I seem to have made the assumption that the parity disk is not part of the disk limit as I have just purchased the basic licence and am trying to configure my 6 data disks and 1 parity but I get a message telling me to consider upgrading my licence. Is this correct? if so I have wasted $10 on my licence as I would need to upgrade a licence I have just purchased? also I am preclearing some disks and the array wont start as too many disks are in the system but they are not part of the array so why wont the array start? they are just inserted for the preclearing process. I hope this makes sense? Many Thanks

Thanks, I have downloaded both and just emptying some disks to put in the Server to try it out... Thanks for all your help

Ah!! That was it!! I feel a little stupid now! Many Many Thanks... that was very frustrating

Sadly not what do I have to do to download this plugin

Hi, I have done that, and now just tried on Microsoft Edge (Was using Chrome) but still the same?

PM Sent... thanks
