During the boot process you can interact with the loader that would be responsible for reading /boot/loader.conf and loading the kernel and modules. When you get to the countdown screen choose the option to "escape to loader prompt" and poke around there to see if you can get it to load in the...

You haven't given us much to work with. What kinds of drives, how are they connected, to what kind of controller? So something like "two Maxtor Atlas 73GB SCSI drives connected by ribbon cable to an Adaptec 39320" would be helpful. Also, install smartmontools and run SMART tests on the...

With three disks in a RAID-5 or RAID-Z, you need at least two disks worth of data to recreate the third disk perfectly if it should fail. If disk 2 is fine, disk 1 has some bad blocks that it hasn't found yet (normally a few bad blocks will just be remapped by the drive, and doesn't warrant...

Enabling TLER for use in any kind of redundant array of disks makes sense, whether it's hardware or software. ZFS behaves a lot like a RAID controller in that, if the drive simply reports that it has a bad block or there is a checksum error, ZFS will try to write the correct data back to the...

I think there's some confusion, I was talking about TLER, and it looks like you were talking about the head parking during moments of idleness. Rereading it now makes more sense. As far as I'm aware TLER doesn't only affect drives on RAID controllers, although RAID cards are much less lenient...

Timeout issues cause disks to fail from RAID arrays. And you'll notice the original post indicates he's getting timeouts. As far as I'm aware, the 4k sector issue just causes terrible performance and probably undue drive wear, but I am not aware of any mechanism by which 4K sector disks would be...

I see far more people having problems with WD Green drives in RAID configurations than any other kind of drive, and I've seen lots of Samsung, Hitachi, and Seagate. Greens won't fail absolutely every time, but it's far from "working fine". There are differences between desktop-class drives and...

For the CPU, anything x86 or x86-64 should work fine. I recommend installing 64-bit unless there's a particular reason you need 32-bit. If you can't think of a specific one, then there probably isn't a reason to use i386. For the GPU, I always buy nVidia because that driver works well for me. I...

I don't know of a PCI card that will work and supports hostap mode. Read the manpage of "run" for a list of compatible cards. I'm not sure if they will currently work in 802.11n mode either, but the card supports it at least. These are all USB: Airlink101 AWLL6090 ASUS USB-N11 ASUS...

It's probably those green drives. Green + RAID = bad. They are consumer class drives not intended for use in RAID. If you google for "wd30ezrx raid" one of the results features the following statement on the page where those drives are being sold:

It looks like you already have SMART tools installed, read the manpage for instructions on how to test a disk. Fully backing up and then restoring the backup to a freshly recreated zpool should fix the permanent errors it's talking about. Another thing you may be able to do is overwrite the...

You can clear the error with "zpool clear". See manpage for more: http://www.freebsd.org/cgi/man.cgi?query=zpool&sektion=8 I do tech support for a major server OEM, and one problem we see occasionally is where you will get a bad block on one disk, and have another drive go offline for whatever...

If you are not booting from the zpool, why are you using gptzfsboot? Shouldn't you have gptboot?

Good GUIs run on almost any platform, and good platforms run almost any GUI. A FreeBSD-specific GUI is unlikely to be a good GUI. You may want to try PC-BSD. Must in order to do what? FreeBSD isn't at war with other operating systems. Must be everywhere in order to do what? I wish it was a...

I use ZFS snapshots and nullfs mounts. There's an article in the handbook (http://www.freebsd.org/doc/handbook/jails-application.html) mentioning using nullfs to have a shared root, with only a few directories not being shared (/etc, /root, /usr/local, /var, /tmp, and /home.) Using nullfs means...

Did you replace both the key and the cert or just the cert? As far as I know the CSR is a certificate signing request and is only used to create the certificate. It isn't used directly by the webserver, only by the SSL signing procedure.

You can use FreeBSD's Linux ABI compatibility and jails to make something resembling an lx zone. http://wiki.freebsd.org/Image/Linux/CentOS55 It's not very polished but it proves the concept is possible.

I don't understand why you would mirror together two such drastically mismatched disks. Put the 10000 RPM disk to some good performance-sensitive use, you're going to slow it down by mirroring it with a 7200 RPM disk. Or sell it to somebody who will, and get another 7200 RPM disk to mirror it...

What's the last thing that it does before it stops doing what you were expecting? That's probably the point where it got messed up. Do you get the boot screen where you press a number key? Does it boot the kernel and then complain that it can't find the root filesystem? Does it just tell you...

It's probably making sure that they are empty by re-emptying them. Specifically it's probably block by block reading off one drive and copying whatever is there to the second drive. (Since there's nothing there, it's rezeroing.) It's the simplest way to be sure that both drives have identical...
