Real-Time Video Recording (ionice equivalent)
Hi, I'm looking for a ionice equivalent for FreeBSD. Let suppose that I setup a NAS using FreeBSD. I can substain 50MiB/s writing. Let suppose that I have a 720p security camera, writing at 2 MiB/s in a file. Then I have 10 users copying files around. All of this activity (camera + users) through Samba, so each connection has a dedicated process. Problem is that I want to give camera's maximal priority to guarantee smooth recording. I don't expect Samba to use much CPU, 99% should be spent in IO. So if I set the nice value of camera's process to Real-Time, it should do much, because its process will be on wait status most of the time. Consequently, when some IO requests coming from camera's process are in the queue, I want them to have top priority compared to requests coming from other processes. As the camera is limited to 2MiB/s, I expect the system to remain responsive. I know that seeks may lower the speed of the HDD, but as the HDD is slowing down, completing requests, I expect the number of camera IO requests to increase in the queue, and to be packed together, hopefully, stabilizing the number of seeks. BTW, I would use root preexec setting of Samba to execute a shell script for each new connection, giving best priority to the process if the user is camera. Any idea?

Re: Real-Time Video Recording (ionice equivalent)
Of course, just like you could put real-time processes in one CPU, and normal processes on another to avoid implement complex algorithms. While your solution is pragmatic, I would like to know if there are clean ways to do it. If not, this would be a documented use case to why would anyone actually need an I/O scheduler.

First, top-posting on this list is considered rude. Please don't do that. Sorry, I didn't want to hurt anyone, I just didn't know the traditions of this mailing-list, I'll be careful from now on. If you're running 8.1, try man gsched, it's new and haven't tried it. Excellent! I can use 8.1, it's for a new setup. Other than that, the traditional way would be to give higher priority to the process that needs it. It's the poor man's io scheduler, but it generally does work well. If you have lots of concurrent io and are running a UFS file-system, consider running gjournal as it scales those requests better. Also if you're hardware supports it, NCQ is available via the ahci and a few other modules. It will make your requests more efficient. Thank you for your tips. I'm happy that I will be able to use FreeBSD for this job.

Re: Lost Root Pasword.
I would have prefer to let someone more experienced speak, but since there is not much answers To reset your root password I think there are two solutions: 1) Boot in safe-mode, I think it will not ask password, and you can juste use the passwd to reset the password. 2) Boot with another FreeBSD install (live CD or so). Mount the partitions you have installed FreeBSD on. chroot then passwd should work. I know it is confuse but I only did that with Mac OS X. Warning: Remember that encrypted partition can only be decrypted using the password. Good luck, Laurent.

You're really funny.

Re: Toshiba Portégé 4000 laptop
Okay the solution is to disable COM and Parallel ports in the bios. (Maybe also USB KB, and USB FDD). To access the bios you have to press ESC while the red TOSHIBA boot screen is displayed, then press F1. (I explain that becaused it's undocumented). With the default settings, I even got the 5.x kernel to panic. Really strange.
