Ciao! qualcuno e' interessato ad aggiungere il supporto fibre channell su xpenology ? ci vogliono un po' di capacita' tecniche e una discreta conoscenza di linux

lsmod |grep i or try to load by hand

Thank you but i don't want to bother Trantor, I was hoping there was someone who can tell me why i have this behavior.

Hi, in my trying to set-up Fiber Channel target on synology i have only one last try, installa compiler into synology, someone could point me on some doc on how-to do it? Many thanks

Nothing, even with braswell compiler, it doesn't work

Which compiler are using to compile xpenology kernel? i saw two of them in sourceforge repos, one called braswell and another called linux-3.2.40 bromolow the first one it seem related to kernel 3.10.35 but our arch it's' bromolow i'm trying to use bromolow compiler to see what happens

Hi, as you can see i'm trying to ad SCST support into synology to see if it's' possible use it as FC target, after a lot of trying i get a strange behavior My setup dev-machine centos7 with all rpm for kernel compiling, synogpl-sources 5644, toolchain bromolow-gcc473_glibc217_x86_64, kernel config from synotest with last xpenoboot bootloader ad last synology update, i used config.ko to retrieve running kernel config. i have expanded braswell sources into /opt/ so i have /opt/source/linux-3.10.x folder with .config from running xpenology system Following howto to compile modules, i use toolchain instead of native dev-machine compiler. All kernel steps goes well all modules are correctly compiled,if i try to use newly compiled module for qla2xxx it doesn't work like the native in synology system, i don't unerstand why if the kernel it's' the same, the compiler it's the same, the .config it's the same, it seems that i lost something or xpenoboot it's' compiled with another compiler or the modules in bootimage comes from original pat file, or, i dont know Can someone helpme to undesrstand? Many thanks

Thank you very much bdazala, i already have all the stuff i need. I'm ecountering some issue with qla compiled driver, I do not understand why qla2xxx module from original synology installation works, but the new one compiled by me in dev-machine not work. If you want i can write HOWTO so you can try by yourself if you have. For my needing i have one syno-test machine with qla installed and one VM with centos7 where i can compile modules.

Yes, but to be sure i have to write all the steps, check if it works, write doc and pray someone who can help me with web-part, it's enough compile only scst and modules, bzImage from compiled kernel in dev-machine it's not needed

Hi trantor, it's not only settings problem, i have to patch kernel source before start compilation because scst subsystem itself need to have kernel patched, you have to start to compile patched kernel, compile modules, make modules_install, after you can compile scst subsystem. Another problem is QLA Adapter, there are several type of them and SCST guys suggest download source from qlogic git and substitute them in kernel tree. If all the things goes well we need to compile userspace part and start to configure it, user space part need to be "hacked" to respect synology layout. I'm afraid that it's not possible to pack all the things in a synopack because it's mandatory to have kernel with patch applied. Hope it Helps, i'm preparing a sort of howto to compile parts.

Thank you but we ar far from to have something usable I had to compile kernel,it's' not enough patch kernel and make modules, but my kernel can't boot into synology system because xpenology use a patched kernel from sancome and others users. i need their help to start one test.

Hi Trantor, i'v build with success al the parts needed using braswell source (Linux-3.10.35) with bromolow config, but i suspect that we have to use vmlinux image and not only modules, as far i can see i can't use my vmlinuz image instead of zImage of xpenoboot, if you want to test i can write a short howto on how to setup environment and so on.

Hi Trantor, thank you for your interest. Fibre Channel support are done via SCST http://scst.sourceforge.net/ it's a kernel extension who permit use of Fibre channel and FCoE, in my particular setup i need only Fibre Channel because i have two HBA ) Host Bus Adapter Qlogic QLA2340 2GB FC adapter, but you can use every FC-HBA is supported by linux. In Synology there isn't any FC support, there is only Driver, and it's' not enough to server FC Target. FC support it's similar to ISCSI support,but it's done via FC instead of IP, another difference it's in howto permit to read particular LUN from particolar host,this involve WWN that you can thing symilar to mac address, you setup a lun to be visible from particular host simply add WWN of the FCHBA present in the host, this is know like zoning a concept similar to Vlan but that involve WWN instead of port. My "project" aim to build a complete synology package, but it's almot a dream because i don't know anything about web programming and so on, my knoweldge it's' limited to follow howto, compile module, compile user-space part and try to see if it works. Basically you need to download SCST package, compile kernel to obtain a regular kernel file, modules and so on, make modules_install to setup all the things, after you can patch kernel and compile scst itself, copy modules and zImage into synology, and try to see if it works. If you need more info, don't hesitate to write, also in PM

Hi Brantje, not something like DDNS that is for internet use. There is bind ( dns server) packaged for Synology, but you have to add any ip address if you want use it, if you setup Synology like dhcp server, any ip served it's not added on dns, dhcpd has the ability to update A record in the zone file served by bind, it's' just a plus for geek and "hackers" it's' not mandatory for home users. Netboot server. I'm a System manager and i need to have several OS to boot, now i have a iso repo where are all the iso of OS, when i need to boot a VM simply connect iso file to vm and that's it. If you want to use a real hardware, you need usb stick or DVD, but if the hardware can boot via network, you can install os via network avoiding the use of any physical support. Another interesting trick is to install a OS into ISCSI target, virtual or physical doesn't matter, the mandatory part it's to have a boot server. Think about the possibilities to boot parted, clonecd and so on via network.

I hope i think would be awesome if we could use Fibre Channel instead ISCSI or both to cover several systems.

Could be fun try to integrate some functions that are not present, for example a real dhcpd server with dns-update, as far you know synology use dnsmasq, adding support for Fiber Channel target, a complete netboot server via ipxe like UDA, and so on. I'm not so skilled programmer but i have some knowledge.

No lucky, i had some trouble on compiling scst even if i setup right kernel source in scst Makefile i need to talk with someone who has programming skills

Tonigth i will try to do some test, i have all the stuff i need, 2 FC hba, one FC cable one esx host and one synology. I don't know if i can use one HBA via VM I would not screw up my synology

Hi, i have sane scenario, but for what i understood it's not enough to have driver, you need to add FC support into kernel, as far i know you have to compile SCST support and user-space part. I'm starting a "project" ( i'm not a skilled programmer ) to try to add FC support to synology. It could be great if we can build a package with kernel parts, user-space parts and web-management to manage WWN lun and so on.

Dovete anche aggiungere una seriale virtuale, altrimenti il cluster non parte

After some try i'v set a synoha HA cluster in VM environment, now works only under esxi because cluster need to setup MTU of heartbeat nic to 9000 and it's impossibile on vmware workstation, another critical step is create a fake serial port to redirect messages, without this the cluster wont start

Hi friends, i need to play with kernel source, which architecture are we using for xpenology? I saw in sourcforge fews arch to download, i would like to know the right for what we are using.

Hi friends, as you know is there some possibilities to use synology via FC-HBA instead of ISCSI?

Potrebbe essere normale in quanto stai usando hardware non synology, in questi casi o ti editi serial number e mac address del tuo hardware o ti appoggi a servizi come DDNS o NOIP per avere un nome visibile in internet

The Jumbo Frame works only if you have your switch configured to handle jumbo frames on ports where the stuffs it's' connected, if your switch do not support jumbo frame, you get all the packets fragmented because the switch ports have MTU fixed as standard ( 1500 or 1492 bytes ) so if you send a big packet the switch cut a big packet in several small like max MTU handled, check you switch and do the right config on every port on which you want enable jumbo frame. At the same way, you have to configure every network card to manage jumbo frame.
