Re: [gentoo-user] Intel(R) C600 SAS Controller
hello again ... noone interested? ;-) I understand in a way ... Maybe I have something in the kernel misconfigured ... Right now I get these messages again: [ 1998.118658] hpet1: lost 1 rtc interrupts Should I disable HPET in the BIOS and/or via kernel command line? I never know how to set the timer-related kernel options, especially with KVM hosting. Stefan

Stefan Hi Stefan, block size / stripe size mismatches only really penalise random io, if you are trying to use dd and have slow speeds this would suggest something else is awry. I don't know the c600 rad chip personally, but in trying to google it it appears to be a motherboard based raid device? is it a real raid or fakeraid? I'm a little confused over your setup to help. i'm sorry if there is duplication but it would be useful to have all info in one hit rather than trying to piece it together from all your messages. 1. please can you list your hardware raid config. I'm looking for the physical disk sizes, the virtual disks and their raid types. do you have cache enabled on the raid card, is there a background scrub or anything like that running? do you have active seek/ prefetch configured ? parity size being 50% of total size is just odd to me - but i guess these are mirrors ? but it says raid-level3 --- just odd, most setups use raid0(not raid) raid1(mirror) raid5(parity stripe) raid6 (double parity stripe) or combinations, like 50.. raid3 is allocating a single disk to parity but is very rarely used. 2. how many other devices are actively doing IO? do you have any other raid cards/io cards of note that might be clashign on the board. 3. do you have active I/O when doing your performance tests? if you have several virtual machines running depending on what they are doing they will crucify your access. 4. are you using any type of CGroups ? 5. i'm also confused over your LVM config. please can you send the output of vgs pvs and lvs -a -o +devices 6. please also send the output of mount 7. do you have atop or iotop that you can use to monitor performance - specifically we are looking for disk ios per device and disk latency per device. both before and during you are trying to run your backup. this should give us a better idea of where the problems lay.

[gentoo-user] Problem with power management of SATA hard drives
Hi there, I'm using Gentoo ~amd64 on my NAS. This is my setup: Mainboard - Asus E35M1 CPU - AMD E350 HDD - 1x 500GiB WD Caviar Green WD5000AADS (root) HDD - 4x 3TiB WD Caviar Green WD30EZRX (Raid10) As these hard drives are desktop hard drives and not designed for 24/7 purposes, I want to spin them down when they are not in use. (And in fact, they will probably be idling most of the time, so let's save energy) I'm able to force spin down those drive by using hdparm -y. hdparm -C then tells me, that they switched from active/idle to standby. Setting standby-time using hdparm -S also seems to work fine: hdparm -S 10 /dev/sdb /dev/sdb: setting standby to 10 (50 seconds) But this does not standby my drive after 50 seconds. So I tried to set the Power Management Level: hdparm -B 5 /dev/sdb /dev/sdb: setting Advanced Power Management level to 0x05 (5) HDIO_DRIVE_CMD failed: Input/output error APM_level = not supported Obviously, my system does not support APM what I can hardly believe... So I tried to enable APM but my kernel configuration doesn't allow me to enable APM support as long as I use a 64 bit kernel - APM option is only available for 32 bit kernels. What am I doing wrong? My hardware is *relatively* new and I don't believe that it doesn't support those power management features. But besides that, does anyone have further tips or tricks to protect hard drives? E.g. try to minimize Load Cycle Count, ... Output of hdparm -I: http://pastebin.com/RyAU6u8T Cheers, Ralf

Ok so the first thing I noticed:
http://dev.gentoo.org/~spock/projects/uvesafb/
You don't have permission to access /~spock/projects/uvesafb/ on this server.
So you need to drop the (gentoo-dev) a line about where to look at his
sources
Now looking at the flags {debug x86emu} I see:
sys-apps/v86d: Use x86emu for Video BIOS calls
If you've been reading the gentoo user list, you can see
much has changed with frame buffers and video drivers recently
in the kernel. The best place to start reading is posting on
25/may/2014 by Greg Turner.
My best guess is changes in the kernel affect your emulation,
and you'll have much digging to do, if the gentoo -dev that
develops/maintains that code does not drop a hint onto your
questions as to waz sup with x86emu.
Are there any notes when you compile it? News? Read the comments
in the ebuild as to new problems?
good hunting.

Thanks. I have a fairly old kernel for other reasons and I installed
v86d in 2011 and it has not changed since. I use udesafb because I
want a frame buffer so I can get a lot more than 80x25 in a virtual
console. Iget 64x160. I also need something which will net the nvidia
driver work since this is the card I have. I did try the noveau driver,
but it did not give me as large of a screen and nvidia driver did not
like that driver. I can't remember what it complained about, but it
means no X at all.

If you're not booting in EFI mode, then you can use vesafb instead. This doesn't require v86d and doesn't even require an initrd. uvesafb is mostly for non-PC or generally platforms where a BIOS is not available (EFI on a PC also lacks BIOS), and it achieves that through v86d. vesafb uses the BIOS directly, so v86d is not needed.

Re: [gentoo-user] Intel(R) C600 SAS Controller
looks promising: virt-backup dumps and packs a 12 GB image-file within ~145 seconds to a non-compressing btrfs subvolume: a) does a LVM-snapshot b) dd with bs=4M and through pigz to the target file The bigger LV with ~250GB is running right now. The system feels snappier than with the old kernel ... I wonder if there is more to tune as right now I am using the rather generic config which is not tuned for the specific CPU, for example (which might even have helped? ;-) ). That was good progress today ... but I might consider re-configuring the RAIDs as mentioned. As I run backups via amanda I have to provide a so called holding disk as intermediate place for dumps on their way to the tape drive. This means copying around stuff within the same hardware raid array. One big fat hw-RAID10 might be better? But losing the wrong 2 drives makes it crash again ... afaik. time for a break here.
