"AUFS" balancing

  • Hey Aaron,


    there is another issue with the balancing feature in AUFS.


    I have on a 5 disk spanned AUFS filesystem some problem with file moving.
    The Pool was successivley englarged. The first disks were already full.
    I have moved (nfs) some large mediafile from a folder on the pool to another
    folder on the pool - with help of filemanager on linux desktop.
    The result of this: error - not enough space on filesystem.
    total AUFS space: ~ 10 TB
    free AUFS space: ~ 5 TB


    It seems the balancing is repeatedly not working...


    can you support me?


    Thank you much

    I haven't been able to test the following command but it worked in this thread. If you are willing to try it and it works, I might add a utility/button to the plugin for this problem.


    find /media/ -type f -name ".wh..wh..opq" -exec rm -f {} \;
    reboot

    It is an aufs issue that I have never been able to duplicate but common enough that quite a few people have posted about. Did the fix work?

    I just wanted you to execute the two commands as root. If that fix they problem, there is nothing else to do. Reinstalling the plugin will not help. This isn't a plugin problem.

  • halo aaron!


    actual status:


    *fix was executed


    *folderstructure on desktop filemanager was still not shown ("AUFS" pool name: AV-Pool, nfs export name: AV-Pool)


    *with this "no folder on desktop" problem i decided to delete "AUFS" pool (name: AV-Pool), uninstalled unionfilesystem plugin and nfs export (name: AV-Pool).

    *installed unionfilesystem an set "AUFS" pool to new a name (av-pool) and nfs export to a new name (av-pool)


    *nfs export "av-pool" with "AUFS" pool "av-pool": balancing seems to work


    the old landingpage "Aufs-Pool" is still on disk with needed files on it. Who can i set "AUFS" to the old landingpage and delete the new? is this procedure meaningfull?


    A few days before the balancing error, i changes permissions to all files to 774. Can this thouch the .wh .wh .opq files and lead to the issue?


    Aaron, thanks a lot for your help!

    Just to get one thing straight... aufs does not alter files on the disk. It works on top of the filesystem. Removing and adding a pool only creates a virtual pool of the files. It doesn't move anything. So, all of your files are still there.


    That said, why did you change permissions to 774??? That can cause a lot of issues. First of all, you won't be able to access directories (the 4 needs to be a 5 for directories) with some users. Second of all, you can't make files executable on data drives. Finally, yes, it could cause issues with aufs.

  • now i deleted my nfs share with the old "AUFS" bind. After this i got the message:



    where can i delete the wrong uuid?
    there no uuid like this in the config.xml


    thanks

  • Hi there!


    Now i have made omv from scratch. I have all old "Aufs" files on the 5 member pool deleted before.
    I setup the new "AUFS" pool on the fresh system, but now i have on 3 of the 5 disk the "AUFS" landing page. What goes wrong there?
    thanks for your help
