When you have an array with uneven disk speeds, you might consider using the --write-mostly option of mdadm: -W, --write-mostly subsequent devices lists in a --build, --create, or --add command will be flagged as 'write-mostly'. This is valid for RAID1 only and means that the 'md' driver will avoid reading from these devices if at all possible. This can be useful if mirroring over a slow link. This should help in concurrent read and write operations because the kernel will not dispatch read requests to a disk that is already having trouble managing the write operations. On another point: Are you sure your disks have different speeds? SATA150 and 300 are no reliable indicator because most HDDs cannot saturate the SATA port anyway. dd is still the most reliable way to measure sequential throughput.

Raid-4(4 disks) was almost as fast as raid-5 so I don't see any sense to use it. Best regards, Bushkov E. When you have an array with uneven disk speeds, you might consider using the --write-mostly option of mdadm: -W, --write-mostly subsequent devices lists in a --build, --create, or --add command will be flagged as 'write-mostly'. This is valid for RAID1 only and means that the 'md' driver will avoid reading from these devices if at all possible. This can be useful if mirroring over a slow link. This should help in concurrent read and write operations because the kernel will not dispatch read requests to a disk that is already having trouble managing the write operations. On another point: Are you sure your disks have different speeds? SATA150 and 300 are no reliable indicator because most HDDs cannot saturate the SATA port anyway. dd is still the most reliable way to measure sequential throughput.

How can I find out which is the parity disk in a RAID-4 soft array? I couldn't find that in the mdadm manual. I know that RAID-4 features a dedicated parity disk that is usually the bottleneck of the array, so that disk must be as fast as possible. It seems useful to employ a few slow disks with a relatively fast disk in such a RAID-4 array. Best regards, Bushkov E. You are seriously considering a RAID4? You know, there is a reason why it was superseded by RAID5. Given the way RAID4 operates, a first guess for finding the parity disk in a running array would be the one with the worst SMART data. It is the parity disk that dies the soonest. From looking at the source code it seems like the last specified disk is parity. Disclaimer: I'm no kernel hacker and I have only inspected the code, not tried to understand the whole MD subsystem. Regards, Florian Philipp Thank you for answering... The reason I consider RAID-4 is a few sata/150 drives and a pair of sata II drives I've got. Let's look at the problem from the other side: I can create RAID-0(from sata II drives) and then add it to RAID-4 as the parity disk. It doesn't bother me if any disk from the RAID-0 fails, that wouldn't disrupt my RAID-4 array. For example: mdadm --create /dev/md1 --level=4 -n 3 -c 128 /dev/sdb1 /dev/sdc1 missing mdadm --create /dev/md2 --level=0 -n 2 -c 128 /dev/sda1 /dev/sdd1 mdadm /dev/md1 --add /dev/md2 livecd ~ # cat /proc/mdstat Personalities : [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md2 : active raid0 sdd1[1] sda1[0] 20969472 blocks super 1.2 128k chunks md1 : active raid4 md2[3] sdc1[1] sdb1[0] 20969216 blocks super 1.2 level 4, 128k chunk, algorithm 0 [3/2] [UU_] [] recovery = 43.7% (4590464/10484608) finish=1.4min speed=69615K/sec That configuration works well, but I'm not sure if md1 is the parity disk here, that's why I asked.

Regards, Florian Philipp Thank you, that's what I was searching for. It seems I configured my RAID-4 right. Nonetheless that array wasn't better than RAID-5. Finally I created RAID-5 (two sataII drives and 1 sata/150) with lvm. From a test time dd if=/dev/zero of=/mnt/gentoo/bigfile bs=1M count=3000 I've got 163 MB/s. That in any way better than my 1-disk system(46.7 MB/s from the same test) that I've been using. As regard interfaces speeds I ran hdparm command and got: livecd src # hdparm -i /dev/sd[abd]|grep UDMA UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 *udma6 UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 *udma6 UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 *udma6 So you are right, all the drives seem to utilize the same interface speed.

And if that fails, here a hint from an earlier thread Recovering Gentoo from a broken python This may be a life saver. I noticed that I have two version of python installed on my Gentoo box. So I thought I'd try uninstalling the old one. This actually uninstalls the latest version libraries leaving me with a warning such as ImportError: no such module time. This is bad as you cannot use emerge at all not even to emerge python to fix things. To fix, as root: cd /root wget http://distfiles.gentoo.org/distfiles/Python-2.7.1.tar.bz2 tar jxvf Python-2.7.1.tar.bz2 cd Python-2.7.1 ./configure make ./python emerge python cd /root rm -rf Python-2.7.1* You are now fixed. Or replace 2.7.1 by 2.6.6 if your system has been running under Python 2.6 before the problem arose. Helmut. Thanks from me too. Lots of good ideas in this thread. I'm glad the thread was there already when I ran into exactly the same thing. I can't even take refuge in claiming to be a n00b -- I've run gentoo on my main machine since somewhere around 2002, when I finished grad school and bought it for myself as a present. (two dual-core Xeons, 2GB DDR ECC, built from parts as suggested as the machine of the year (or something like that) by Linux Journal). I wound up with Gentoo because slower-release distros did not have kernels that knew how to configure such a machine -- I never figured out if it was the Xeon stuff or just SMP. Anyway, an up-to-date kernel avoided it triggering clock slowdowns. Nothing like having a state-of-the-art machine that persists in running at 10%. I do try to get elogs by email, but its flakey for some reason. But some of those other steps mentioned above I've never heard of before. Time for a little studying (sigh). -- Kevin O'Gorman, PhD

[gentoo-user] videos that won't go away.
Hi folks, I noticed something weird but I'm not sure what to even search for to get a fix. When I play a video with Seamonkey or Firefox, then close the tab or close the browser, the video is still there. If the video contains text, it is really noticeable. It's like a freeze frame of what ever was there when I closed the tab or browser. It does this in both Seamonkey and Firefox. The video affects my desktop wallpaper or background, Konsole, Kpatience, and any other program I have open. It is weird. Some programs like Konsole, which is running as root, just sort of distort in some weird way. The only way to correct this weirdness is to log out of KDE and back in. That returns everything back to normal. Closing the app I was using to play the video does not work. If I use Firefox and download helper to capture the video and save it, I can play the video with Smplayer with no ill effects. It plays and closes just fine. It's just when I use Seamonkey or Firefox that this happens. I have upgraded the kernel and had upgrades to both Seamonkey and Firefox. I have recompiled the nvidia drivers as well. The nvidia drivers, kernel and other info is here: root@fireball / # equery list seamonkey [ Searching for package 'seamonkey' in all categories among: ] * installed packages [I--] [ ] www-client/seamonkey-2.0.14 (0) root@fireball / # equery list firefox [ Searching for package 'firefox' in all categories among: ] * installed packages [I--] [ ] www-client/firefox-3.6.17 (0) root@fireball / # equery list nvidia [ Searching for package 'nvidia' in all categories among: ] * installed packages [I--] [ ] media-video/nvidia-settings-260.19.29 (0) [I--] [ ~] x11-drivers/nvidia-drivers-260.19.44 (0) root@fireball / # equery list xorg [ Searching for package 'xorg' in all categories among: ] * installed packages [I--] [ ] x11-base/xorg-drivers-1.9 (0) [I--] [ ] x11-base/xorg-server-1.9.5 (0) root@fireball / # uname -r 2.6.38-gentoo-r3 root@fireball / # I have not tried a emerge -e world yet.

[gentoo-user] QA Notice: libdialog.la appears to contain PORTAGE_TMPDIR paths

I just installed a Gentoo box and i am having a bizarre problem (bizarre for
me at least), i'd like to point that the only solution i have found so far
(attempt to modify some eclass) is way beyond the limit of complexness that
i am used to so if there is another way i would really appreciate if anyone
pointed it out for me

and linux in general
anyway, thanks in advance!!!

Try killing flash so it restarts to see if that helps get things working. Sometimes my system needs a full reboot - even restarting X doesnt help.

How silly of me. lol One thing I just noticed, it doesn't always do this. I went back to a link that did it just before I posted and it worked fine this time. So, this appears to be a intermittent problem which opens a new can of worms. We all know how hard it is to fix those. I'll try killing flash next time it does it and see what that does. Dale :-) :-)

Have you checked if xulrunner and the adobe flash plugin is still running *after* you shut down seamonkey/FF? I noticed on a 32bit machine that the latest stable xulrunner/FF update (or was it the nss nspr libs that caused this) has increased both CPU memory consumption, but can't say for sure. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

The thing is that emerging mirrorselect has the following outcome: * QA Notice: libdialog.la appears to contain PORTAGE_TMPDIR paths * ERROR: dev-util/dialog-1.1.20100428 failed: * soiled libtool library files found Hmm ... I don't know why this is caused, but I would run: emerge --oneshot -av libtool and then revdep-rebuild -v -- --ask -- Regards, Mick signature.asc Description: This is a digitally signed message part.

That I have not tried. I do think that it got worse after the upgrade of flash. I can't recall which version was the last that did it tho. I have upgraded flash stuff and browser stuff so I can't point to which is causing what. I have noticed a larger use of memory tho. I have 16Gbs here and it uses a good bit more than it used to. Maybe another upgrade will reduce it back down. Wonder why programs have to use so much now? Maybe the new html5 will change that. ;-) I'm waiting on it to do it again. It is random but I don't recall it ever doing it on youtube. I spend a lot of time there. lol Dale :-) :-)
