E-SATA?
Hi everyone,
I need an sftp-server and would like to set it up with OpenBSD. The server will do nothing but sftp. It should have two e-sata drives connected and mounted in the sftp home-directory. The server will be connected directly to a DSL-line and the e-sata drives will be the only way to exchange data with machines inside the network. Now my questions: Does OpenBSD support E-Sata at all? I could find any information about it And if it does, how stable is it? TIA for your help! |

E-SATA is the same as SATA, just with different standards for connectors, size, etc., from http://en.wikipedia.org/wiki/Sata#External_SATA :

Mh, yeah I knew that, but what about controllers and adapters?
What I'm also a bit afraid of is stability. With FreeBSD, I have had so many problems using USB. whenever I unplug a device, I bet my rear end sooner or later it will crash and freeze to death until reboot. |

The complete list of supported hardware for each architecture platform can be found by looking through your intended architecture web page at:
www.openbsd.org/plat.html Please look there. |

It's funny you mention that. I just had a 2T USB-drive connected to this machine here, did not even mount it, merely plug in, partition and unplug. When I came back 10 minutes later: FREEEEEEEEEEEEEEEEEEEEEEEEEEZE |
|

But I don't want the system to debug, I want it to work
Or should I go to my boss and tell him "I know our customer's pissed because the machine crashes every hour, but hey! We got that nifty blue debug-screen!" ? |

If you are unwilling to diagnose your own problems, may I recommend a commercial support contract? See www.openbsd.org/support.html for a list of companies and their services, world wide. You might consider outsourcing hardware selection, also.[/Soapbox] Wrong attitude, Patrick. See http://daemonforums.org/showthread.php?t=596 for our hope, if not our expectations. |

jgimi, with all respect, but I am not paid for debugging.
I have had the very same problem with three different BSDs: OpenBSD, FreeBSD and PCBSD. Each one sooner or later froze when unplugging a USB-device. Some did not for hours, sometimes a device did not freeze it at all. Yet, I have tried various machines with various usb-devices with various cables and various locations. The only thing they had in common: BSDl. Conclusion: If I have a critical task with USB => NO BSD. I have more than ten years of systemadministration in my fingertips, and almost 8 with BSDs, as well as Sun, SGI etc. I doubt I'll need some funny lesson telling me where to find hardware errata or commercial support. If you don't have any other assistance to offer: Thank you and have a nice day. The question remains, does anyone have experience with ESATA and is it stable with OpenBSD. Because until gettin paid for spending a week or two trying and testing if it works: No way. |

That was unbelievably rude PatrickBaer..
If you're not going to act civilized.. on a community created by BSD enthusiasts for BSD enthusiasts, then leave us in peace. System administration implies a sort of responsibility, if you seek out help.. but at the same time are unwilling to follow expert advice, you've most definitely chosen the wrong career path in life.

Detaching USB device without umounting it is known problem, and on FreeBSD side it is fixed (in 99% situations) on STABLE/HEAD branch. |

How exactly he or she makes them work is not really important to whoever is paying you ... If debugging is what's necessary, then that's what's necessary. I realize you're not in a pretty situation, in fact, it downright sucks, but this is a drawback of using (a free) operating system primarily developed in people's spare time, and with little or no commercial support ... No one owes you anything, The OpenBSD people will fix it when it suits them, which may be tomorrow, or it may be in a year ... Or maybe never. All that you (As a non-developer/programmer) can do is to provide as much accurate information to describe the problem as you can, which will make it easier for the OpenBSD developers to locate and fix the problem/bug. This is simply how free operating systems (Such as FreeBSD, OpenBSD, Linux, etc.) work.

Hey Carpet, no problem at all. We two have different points of view, so what? My opinion about things like this USB-stuff is quite simple: Don't do it. I cannot risk my head using a system which will almost definitely run into severe problems. So I won't waste my time doing things like this but stick to the stuff I know it works. I have had dozens of systems with BSDs for all kind of purposes, Mail, Apache, Newsserver whatever. All worked just fine. But use them for USB? No
I got no idea, how you people work with BSDs: At home, at work, at school. Do you have a single fileserver or a 20 machine database cluster? But if you have a sales-guy, customer support, the CEO and a bunch of cutters behind you, you'd better think twice before using a "is most probably not really working 100% ok but with a bit of luck it will after a week or so of work spent on it"-system. I am still in the situation: I need a machine with the ability to hot-swap ESATA-drives. And I came in here to ask for opinions, maybe someone has worked with external drives and knows about bugs and limitations, maybe can recommend controllers and so on. But instead of qualified opinions people send me links to hardwarelists Oh, BSDFan, just a little note: That was my "whipcream with sugar on top"-version. I actually have no idea what you are so shocked about, just like I have no idea why you feel involved at all? Oh well... Back to topic, if someone really has experience, with ESATA, please tell me. |

FWIW, eSATA can be found in the misc@ archives in three threads. In addition, it is specifically mentioned on the OpenBSD website only in reference to OpenBSD/socppc hardware connectivity. |
