It's an option that you afaik can only set on filesystem creation and therefore needs a restart from scratch if you get it wrong. According to the illumos wiki it's possible to run a mixed pool (if you have drives requiring different alignments[1]) If in doubt: ask ryao (iirc given the right information he can tell you which are the right options for you if you can't deduce it yourself).

[gentoo-user] Unable to catch kernel crash dump
I've been getting a kernel oops for awhile that is worse than ever in 3.11.1. It seems to be related to my XHCI USB port. I followed the instructions here: http://wiki.gentoo.org/wiki/Kernel_Crash_Dumps but /proc/vmcore doesn't exist after I reboot the system after a crash. I did notice that I was getting a lot of white text dumped to the screen against a black background before I followed the instructions in the wiki, but after following them the screen just freezes when it crashes. Does anyone know what I might be doing wrong or how to find out? - Grant

No need to analyze further. The reason I said that because in the future, *all* drives will have 4 KiB sectors. Currently, many drives still have 512 B sectors. But when one day your drive dies and you need to replace it, will you be able to find a drive with 512 B sectors? Unlikely. That's why, even if your drives are currently of the 'classic' 512 B ones, go with ashift=12 anyway. For SSDs, the situation is murkier. Many SSDs 'lie' about their actual sector size, reporting to the OS that their sector size is 512 B (or 4 KiB). No tool can pierce this veil of smokescreen. The only way is to do research on the Internet. IIRC, a ZFS developer has embedded -- or planned to embed -- a small database into the ZFS utilities to conclusively determine what settings will be optimal. I forgot who exactly. Maybe @ryao can pipe in (hello Richard! If you're watching this thread, feel free to add more info).

[gentoo-user] Kompozer, anyone?
Hi list, I used to use Kompozer (part of the Mozilla suite) but time has passed and now the libraries it needs are no longer in portage. That's using the binary. Attempting to build it from source according to these instructions [1] fails too because the script can't find some other libraries. The project seems to be dead, or at least moribund, and hasn't been updated since version 0.8b3 which relied on gcc 4.2. Has anyone managed to get it to compile? Or maybe there's another WYSIWIG HTML editor? I use BlueFish most of the time, but just occasionally Kompozer has been useful too, and it would be a shame if it just died. -- Regards, Peter

I would like to build sane-backend only for one specific scanner. However, there are a huge lot of different USE flags for other scanners that are already switched on by default. Is there any easy way to switch them off? Something like: media-gfx/sane-backends -sane_backends* sane_backends_hp Exactly that way does not work, but may be something like that... ...instead of directly switching off every one of them.

According to the Package Manager Specification, the variable should not be incremental, i.e. any value set would override *any* defaults or previously set values. So just do SANE_BACKENDS="xxx" in your make.conf, same as what you'd do for VIDEO_CARDS and the like. Hope it helps :)

HiFrank, thanks for your help! I will try to use it as *help. :) Whats interesting with all that is: "previously" (read "before that problem") everyhing works fine. And then ...once in a sudden... "something" had shuffled the channels. Is there any /sys/... or /proc/... entry to which I could shout "stereo" to switch back to good 'ole stereo instead of this surround stuff ? Best regards, mcc

[gentoo-user] re: duplicated packages
Howdy, Is having duplicate packages a good or a bad thing in gentoo? I'm clear about having duplicate packages for the kernel. I'm using the more recent one, but hanging on to the old one just in case. Perhaps, the reason for having duplicate packages is the fact that various packages I have installed on the system may require a different version of a package I may already have installed. Is that it? _box0=; equery list --duplicates '*' * Searching for * ...

You'll see people argue for both sides at this size, but the 'saner default' would be to use RAIDZ2. You're going to lose storage space, but gain an extra parity drive (think RAID6).
