ZFS on Linux & mplayer

Hi,
I have a problem with the combination of zfsonlinux and mplayer.
Actually I'm not quite sure if one of them is the culprit, but I have some pointers.
Problem: When playing a movie (e.g. a mkv ~ 2GB or a vob ~ 6GB) every few minutes the the movie shortly stutters (picture & audio)
Observations:
1) This didn't happen with zfs-fuse which is supposedly slower than zfs on linux.
2) I can copy a vob file in under a minute to my home directory (ext4), hence read performance should be reasonable.
3) When playing the movie from my home dir, no stuttering occurs. Hence I'd rule out an mplayer or sound card issue.
Now I don't know what I can do about zfs on linux. Read performance seems to be ok and there seem to be no sound card issues. When I run bonnie or iozone, cpu usage stays below 20%, so that shouldn't cause an issue as well.
Any hints or tips on what I could look at next? Thanks!

Nfs + zfs on linux

How do you use nfs + zfs on linux? I vaguely remember that there was some nfs functionality built into zfs, but i'm not sure if that works on linux also.
Currently i am using the standard nfs export method described in the wiki, which has the problem that bind mounts must happen after the zfs-mount service, and requires me to use a mount unit.

[SOLVED] What is the best way to use ZFS on linux-ck?

Hi, I've recently gotten into ZFS to replace my Intel FakeRaid array I had set up for my /home folder. All is well under the stock kernel, but I'm running into issues while trying to run it under linux-ck.
At boot systemd throws a fit, and in the emergency shell it seems that -CK cannot use the installed module (module not found). I noticed that the versions for -ck and -arch are currently slightly different, and tried recompiling -ck to match -arch's version to no avail.
Inspecting the PKGBUILDs for the zfs packages, it looks like they're designed to be built for the current [core] version of the stock kernel only, which would explain why -ck can't see the zfs module.
Is there an elegant, semi-automatic way to go about maintaining zfs/spl so that I can keep it up-to-date for the current linux-ck version?
Thanks!

Okay, I was thinking it would be something along those lines. Thanks for the clarification.
After I modify the PKGBUILDs to use linux-ck, I should be able to build the modules against -ck even if I'm currently running -arch, correct? Just want make sure, since I'd like to avoid breaking ZFS on both kernels at the same time so I don't have to deal with some awkward situation where I need to build the modules against -ck from the emergency shell or something.

Oboy. http://github.com/behlendorf/zfs

I've tried making PKGBUILD's. And spl build and installs fine, but I get a building error on zfs:

WVC80N problems - linux mplayer capture, FTP issues

This camera was very stable for months, not sure what that heck happened about a month ago.
First off, only use this on Linux OS. I use mplayer to capture a still image every minute. Used to be very stable, for weeks on end (the linux way!). About a month ago the cam would just freeze, I could access the cam through the network but could not capture an image (either viewing on network page or via mplayer). The only way would be to reboot the camera and all was fine for a few hours before it would freeze again. I have not been able to fix this problem.
Now I decided to try the motion detection FTP feature. No luck, I cannot get the cam to find my ftp server. I can access this server from my other computers (including my windows box). I opened the port, no dice, nothing. Never seen an image saved via the motion sensor FTP option.
I anyone out there able to use the FTP feature (preferably on linux)??
Thanks so much for any help or feedback on this...

Problem solved. I finally got around to reading the manual and the answer was right there in an appendix. Using linux all you need to do is...
curl -o 00000001.jpg http://192.168.1.115/img/snapshot.cgi?size=3&quality=1
Substitute the ip address of your cam. I save a time dated file and send it to my web server and can run a time lapse of my cam. Been very stable so far.
Hope this helps someone,

(Native?) ZFS on Linux. Hmm...

http://www.phoronix.com/scan.php?page=n … &px=ODgyNA
Has anybody tried any of that? I'd like to see a PKGBUILD or something.

Do you really expect a FS with end to end checksumming and such a large amount of features to be as fast as a "basic" filesystem?
ZFS is first and foremost about data integrity and scalabilty, anything else is secondary.
Consider a mirror setup using a standard FS , if a bit of data gets screwed on drive 1 then the same bit of data gets screwed on drive 2, not so with ZFS. With the checksumming drive 2 recognizes that bit of data is corrupted and self-heals it with the correct data.
Compare creating mirrors, RAID5, LVM's etc between a normal FS and ZFS, ie RAID 5 with 1 disk for parity
zfs create tank raidz1 /dev/ada0 /dev/ada1 /dev/ada2
Snapshots.. its simple to roll back to any of these points in time.

I'd really suggest looking at all the things ZFS offers and then how fast it is all things considered, my workstation storage pool uses mirrored WD caviar blacks 1TB's and gets 250MB | 109MB read/writes, pretty fast enough.

Trouble installing ZFS in archlinux kernel 3.6.3-1-ARCH

@modular, You're trying to build with the 3.6.2 kernel. The current version (rc11) does not work with the 3.6.2 kernel. If you want to use it, you will have to downgrade to the 3.5.6 kernel (linux and linux-headers). https://wiki.archlinux.org/index.php/Downgrading_Packages
Thanks!
Comment by: MilanKnizek on Wed, 24 Oct 2012 08:07:19 +0000
@demizer: there still seemed to be a problem during upgrading - zfs/spl requires kernel of certain version (hard-coded) and this blocks the upgrade (the old installed zfs/spl requires the old kernel and kernel can't be upgraded w/o breaking dependency of zfs/spl and therefore build of the new zfs/spl fails, too).
So far, I have had to remove zpl/spl, upgrade kernel, rebuild + install spl/zfs and manually run depmod against the new kernel (i.e. the postinst: depmod -a does not work until next reboot) and only then reboot to load the new kernel zfs modules successfully.
That is quite clumsy and error-prone - I hope it will be resolved via DMKS.
Comment by: srf21c on Sun, 28 Oct 2012 04:00:31 +0000
All, if you're suffering zfs kernel upgrade pain fatigue, seriously consider going with the LTS (long term support) kernel. I just successfully built zfs on a system that I switched to the linux-lts 3.0.48-1. All you have to do is install the linux-lts and linux-lts-headers packages, reboot to the lts kernel, and change any instances of depends= or makedepends= lines in the package build file like so:
Before:
depends=('linux=3.5' "spl=${pkgver}" "zfs-utils=${pkgver}")
makedepends=('linux-headers=3.5')
After:
depends=('linux-lts=3.0' "spl=${pkgver}" "zfs-utils=${pkgver}")
makedepends=('linux-lts-headers=3.0')
Then build and install each package in this order: spl-utils,spl,zfs-utils,zfs.
Worked like a champ for me.
Comment by: stoone on Mon, 29 Oct 2012 12:09:29 +0000
If you keep the linux, and linux-headers packages while using the LTS you don't need to modify the PKGBUILDs. Because the checks will pass but it will build the packages to your current runnning kernel.
Comment by: demizer on Mon, 29 Oct 2012 15:56:27 +0000
Hey everybody, just a quick update. The new build tool I have been working on is now in master, https://github.com/demizer/aur-zfs. With it you can build and package two different groups of packages one for aur and one for split. Again, building the split packages is more efficient. I still have a lot of work to be done, but it is progressing. I will be adding git, dkms, and lts packages after I setup my repo. My next step is to add unofficial repository support to my build tool so I can easily setup a repo with precompiled binaries. I will be hosting the repo on my website at http://demizerone.com/archzfs. Initially it will only be for 64bit code since the ZOL FAQ states that ZOL is very unstable with 32bit code due to memory management differences in Solaris and Linux. I will notify you all in the future when that is ready to go.
@MilanKnizek, Yes updating is a pain. ZFS itself is hard-coded to linux versions at build time. The ZFS build tool puts the modules in "/usr/lib/modules/3.5.6-1-ARCH/addon/zfs/", and this the primary reason it has to be rebuilt each upgrade, even minor point releases. Nvidia for example puts their module in "/usr/lib/modules/extramodules-3.5-ARCH/", so minor point releases are still good and the nvidia package doesn't need to be re-installed. A possible reason for ZOL to be hard-coded like this because ZOL is still technically very beta code.
I do have a question for the community, does anyone use ZFS on a 32bit system?
Thanks!

I am not able to compile this package after the upgrade to the 3.6 kernel. Anyone else ? any idea?
Comment by: mikers on Mon, 15 Oct 2012 23:34:17 +0000
rc11 doesn't support Linux 3.6; there are some patches on GitHub that might apply against it (I've not done it myself), see:
https://github.com/zfsonlinux/spl/pull/179
https://github.com/zfsonlinux/zfs/pull/1039
Otherwise downgrade to Linux 3.5.x or linux-lts and wait for rc12.

@vroomanj, I plan on working on the git packages this weekend. All I have to figure out if it is going to be based on an actual git clone or if its just going to be the download links you provided. They are pretty much the same, but i'm not really clear what the Arch Package Guidelines say about this yet. Also, I don't think the current packages in AUR now should be based off of git master. They should be based off of the ZOL stable releases (rc10, rc11, ...). That's why I am making git packages so people can use them if they want to upgrade to the latest kernel and the stable release hasn't been made yet. As is the case currently.

Did you read the comments, either on the AUR page or in the output that you posted? They explain it.

Thoughts on ZFS-FUSE stability?

I'm considering putting ZFS on my home file server for the data drives, and setting it up for mirrored RAID. I was wondering if anyone had any experiences with it as far as stability and data loss, good or bad. Performance isn't a HUGE concern, since it's just for my own use. I do keep backups on an external hard drive in any case, but that's one of those things you hope you never have to use.
So has anyone used ZFS-FUSE extensively, and if so, how was your experience with it? Is it ready for prime time, or not?

Well, since few people seem to be talking about the current state of ZFS on Linux, I'll offer my experience:
Other than a solvable bug preventing some filesystems from NFS export (affects ZFS and other FS as well), I've found ZFS-FUSE to be a pleasure to use. ZFS is much more mature than BTRFS and I think a production-functional kernel module is not far away. BTRFS has had recent data loss issues and I wouldn't trust my important data to it yet.
I am running a 4-disk RAIDZ2 setup with 4 2TB disks that gives me ~3.7TB of usable space with dual redundancy. If you decide to expand your storage, ZFS makes it a breeze. NFS exporting with ZFS is also super easy, as long as you organize your ZFS 'filesystems' properly. It's a bit different thinking about ZFS filesystems but I really like it (individual permissions and sharing settings, variable size, nestable) now that I'm used to it. I also have no trouble sharing the filesystems over Samba to my Windows boxes.
ZFS-FUSE is not blazing fast but it's fast enough for my NAS running backups and serving high-bandwidth media. The self-checking/self-healing feature gives me a calm feeling about data I haven't had before. It's easy to get status and statistics about the current state of the FS from the zfs and zpool commands. I only wish I'd switched my NAS to ZFS sooner!
EDIT: This post by a BSD user describes well how I feel about ZFS:
ZFS is not just only another filesystem. And there are faster filesystems out there.
But if you need the features of ZFS, it is the best you have ever worked with.

Is there any shadow copy in linux

If you use ZFS on Linux (not that I'm saying you should) you get a third way to do this as well.

Shadow Copy in Windows is actually a feature that Linux had long before and Microsoft was embarrassed for going so long without having it. It's famously one of the big "finally Windows is catching up" features where every OS had it years before them.
Shadow Copy is just another name for snapshots. Linux uses LVM as its main snapshot tool although snapshotting is starting to appear as an extra tool in BtrFS too.

Questions about ZFS

Hello
After having some serious issues with data corruption on ext3 and 4 over time, I have decided to start using ZFS on the disk. After what I have read, ZFS is the superb filesystem for avoiding data corruption, as far as I have understood zfs-fuse (http://aur.archlinux.org/packages.php?ID=8003) to use zfs with linux, or is there any better option?
And Ive heard that zfs requires alot of the machine? And is there any other alternatives?

he means until it's stable in the kernel. which could take a loong while I think. (personal guess: 2 years or so)

Problem with partitioning - disk permanently falls back to old p-table

Hey Guys!
I'm quite desperate and can't find answers for the following problem - maybe some of you already had a similiar problem.
I want to reuse a SSD that I used on a different machine as primary system drive. It's partition-table:
# fdisk -l /dev/sda
Disk /dev/sda: 119.2 GiB, 128035676160 bytes, 250069680 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x0004f0e5
Device Boot Start End Sectors Size Id Type
/dev/sda1 * 2048 499711 497664 243M 83 Linux
/dev/sda2 501758 250068991 249567234 119G 5 Extended
/dev/sda5 501760 250068991 249567232 119G 8e Linux LVM
There is a LVM volume group with two volumes (root and swap) on sda5. No matter how I try to destroy the LVM setup and the partitioning, it is always "reseted" to this setup.
I tried: lvremove, vgremove, pvremove, fdisk, cfdisk, gdisk, cgdisk, dd from /dev/null, testdisk - with and without reboots, from arch-linux booted from usb and from an ubuntu-live-cd. No matter what, the partitioning does not change.
Why I want to reformat it? I want to use the drive as cache for zfs-on-linux.
It feels like the drive is somehow write-protected.
Has anyone suggestions what to try next?

Thanks @ROOKIE
Sadly didn't work either - see below. Underneath I added results of smart-tests - maybe I miss something.

Vp7 codec - any way to play or re-encode it?

Hi,
I have several videos encoded with vp7 (or vp70, as mplayer tells me).
Is there any way to play or re-encode to some other coded on a 64 Bit arch linux system?
Thanks!
Nathan

I know, old topic, but solution does exist. Just install codecs from AUR. It's some kind of "K-lite codec pack" for Linux, Mplayer works with them perfectly

K8N Diamond+ 6600GT=green videos

hello.
i have the following problem: since i upgraded my system to winchester 3000+, msi K8N diamond sli and msi 6600gt pci-e all the videos (avi + mpg) are shown in green, a green checkpattern or even freeze the system.´
first i tought it may be a codec prob, but uninstalling and installing correct codes and even trying playerz with build in codecs such as the (linux) mplayer - but that didnt help.
so, at last, i reinstalled my system:
1. windows xp pro
2. sp 1a
3. 6.37 mobo drviers (i am using that beta dirver, since all other mobodrivers cause problems with online gaming and surveyprogs like everest, butnevertheless i tried official drivers as well-still didnt help)
4. directx 9c
trying to play a video with the mplayer works as fine as it should without a videocard driver.
but as soon as i install a videocard driver the above discribed problems reoccur.
i tried various drivers, starting from the 66.93 from nvidia hp, the msi dirver from the cd delivered with the vidcard, the drivers form msi hp, and of course plenty of drivers i found on guru3d.com, including the latest 71.80, nad "old-school-drivers" like 66.00.
i testet the temperature via everest. in idle mode cpu and gpu are below 40°C. bios proves everest right. so it cant be a temp prob.
i had no problems, artefacts , whatsoever during the benchmarks (3dmark2001/2005). also Call of Duty and Doom 3 run perfectly for hours.
only Warcraft doesnt want to start....i get a green screen at the very beginnig...i suppose that is due to the video that is played at wc3startup.
with one beta driver (i think it was 66.10) i was able to activate hardwareoverlay, which did help playing videos "better", but then wc3 claimed it couldnot find directx. testing via dxdiag it showed direct 3d produced mistakes. asking google i decided to deaktivate all the none necessary crap in the bios (sil-controller, marvell lan, craetive sound) to avoid irq problems.
that made dxdiag happily testing the direct 3d, but still videos are green.
strangely, now i even cant choose that hardwareoverlay option anymore, and i havent found it in another driver yet
it seems that quicktime movies cause no trouble.
thinking it might be a problem with the 32bit mobo drivers i even installed the win xp pro 64 rc1 on my other hdd, putting on the brandnew 64bit mobo and vidcard drivers - same problem here.
this problem has kept me hostage for days and i start feeling a little despaired.
i was mighty happy if anyone could help me.
sincerely,
ben
ps: english is not my first language, so please apolgise bad grammar and spelling

thank you very much for your reply, wonkanoby.
i tried various codecs and playerz with build in codecs. i even reinstalled my system 3 times - still videos are green with an vga driver installed.
also the fact that it does show videos correctly when no vga driver is installed shows it is not a codec problem.
annybody got other ideas?
sincerely, sick nick

How to recover/update GUID_EXTERNAL between ODI and WLS

HI All,
        I have lost my all security in a OBIA 11.1.1.7.1 environment, and I'm trying to recreate it. I've already recreated at WLS the following users biappsadmin (my OBIA admin user), BIAppsSystemUser and BISystemUser.
       I've got to log into OBIEE again, but when I try to log into ODI Studio I've got the following error :
oracle.odi.core.security.BadCredentialsException: ODI-10163: This OPSS user biappsadmin has different GUID than the one found in Oracle Data Integrator repository.
at oracle.odi.core.security.SecurityManager.createAuthentication(SecurityManager.java:511)
at oracle.odi.core.security.SecurityManager.createAuthentication(SecurityManager.java:252)
at oracle.odi.ui.docking.panes.OdiCnxFactory$1.run(OdiCnxFactory.java:208)
at oracle.ide.dialogs.ProgressBar.run(ProgressBar.java:655)
at java.lang.Thread.run(Thread.java:662)
     Then, looking at SNP_USER from <prefix>_BIA_ODIREPO I have the following :
I_WUSER                    --> 2500
WUSER_NAME          --> biappsadmin
WUSER_INIT               --> null,
PASS                         --> null,
AUT_SUPERVISOR     -->1,
FIRST_DATE               -->null,
FIRST_USER               -->null,
LAST_DATE               -->null,
LAST_USER               -->null,
IND_CHANGE               -->null,
EXT_VERSION            -->null,
EXPIRACY_DATE       ->null,
I_TXT_DETAIL             -->null ,
USER_EXPIRACY_DATE --> null,
GUID_EXTERNAL          --> 7D635A9155BD11E38F07A52086C80F5C
    So, Is there a way to know what is the GUID that WLS has created to this user ? If dont, How to recover the security ?
Thanks in advance...

I googled it, but can't find the solution. Would you explain it a bit, for example, the PKGBUILD below, how to change it to let it compile against a specific version kernel? Thanks.

How to embed mplayer in Linux with JNI

Hello All,
I was wondering if anyone here knows to get a Linux based video player to draw on the awt Canvas. I am trying to play the streaming video in ASX / WMV format on Linux. And MPlayer is one such player that can play almost anything.
For windows, there are a few options to embed the native media player and I am thinking of going with jawin as it hides most of the native implementation. But I have not much idea about how to do it in Linux. Couldn't find many examples / guides either.
If someone has an idea / links and would like to share it, it'll be highly appreciated.
Thanks in advance,
Rex

I could advance a little more and got the JNI library to draw on the awt Canvas. But still can't get another native program like gedit to draw on the Canvas.
This is what I am doing to draw the rectangles (from Sun's example) -
gc = XCreateGC(dsi_x11->display, dsi_x11->drawable, 0, 0);
XSetBackground(dsi_x11->display, gc, 0);
for (i=0; i<36;i++)
XSetForeground(dsi_x11->display, gc, 10*i);
XFillRectangle(dsi_x11->display, dsi_x11->drawable, gc,
10*i, 5, 90, 90);
XSetForeground(dsi_x11->display, gc, 155);
XDrawImageString(dsi_x11->display, dsi_x11->drawable, gc,
100, 110, testString, strlen(testString));
But how do I pass the handle 'gc' to another program like gedit to draw on this surface instead of opening it's own window ? It'll be a great help if someone could share an idea on this.
Thanks,
Rex
