  • How to hange disks 5x2TB for 3x8TB with mergerfs and SnapRaid on live system

    Hi,

    i plan to change my disks which are 5x2TB (4x2TB as data disks and 1x2TB as parity in SnapRaid) for 3x8TB (2x8TB data and 1x8TB parity). I am using mergerfs and SnapRaid. On 2TB disk I have shared folders which are used for some services (database, Public_html, KVM, Docker, etc.).

    What is the best practice to transfer data to bigger disks and have no problem with running services which are pointed to shared folders on data disks?

    1. I mean that 1.st step is to stop all services which are using data disks (if it is possible on running OMV).

    2. Then copy data from smaller to bigger disks (it should not be a problem to move all the data from the small disks to one large one) - how to copy data to preserve access permissions?

    3. change shared folders paths to new disks

    4. change paths in services (database, nginx, KVM, ...)

    5. start Services and setup SnapRaid (sync)


    Am I right with these steps? Or did I forget something?

  • New HDD added, how to link folder to UnionFS subfolder

    Good day to all,


    my config:

    4x2TB HDD + 1x500GB for OS


    3x2TB (data disks) are linked in UnionFS (Ulozisko) and 1x2TB is spare disk (all are linked in SnapRaid).

    Folder (Ulozisko) is shared to network. I have subfolder called "Nahravky" in "Ulozisko" which is used for my STB to record movies. Now i need move this folder "Nahravky" to new disk (500GB).

    I need use this 500GB HDD only for recording movies from STB. How can I setup this? I don not want to setup my STB from beginning to access to new shared folder on NAS.

    Is it possible somehow to simlink my folder "Nahravky" from array UnionFS to new HDD? Or is there other way to setup?


    Thank for any help.

  • Docker - problem with permission

    Problem resolved. Probably Unionfs was the cause.
    In Docker is base path (/var/lib/docker) an I set it to my data disk via Unionfs (/srv/xxxxx/). When I set it to default (system disk with OS) all is working.
    I try set direct_io=disable but had some errors - set it back to enable.


    Now I have Docker system files on OS drive and contained data on Data drive (direct path - /media/xxx not via Unionfs)

    Can anyone help with this problem?

  • apt-get update error

    When trying to update OMV:



    It is some problem with public key? How to repair?

  • No updates via GUI, errors via CLI

    Hi,


    few days ago I noticed that no updates for OMV are in GUI (Update Manager) but I received mail with info about new updates daily (cron). When I try to manually refresh new updates via GUI - no new updates.
    When try to update in CLI (apt-get update) I get this error:

    Code
    Fetched 820 B in 8s (98 B/s)
Reading package lists... Done
W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://apt.spideroak.com release Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 573E3D1C51AE1B3D


W: Failed to fetch http://apt.spideroak.com/ubuntu-spideroak-hardy/dists/release/Release


W: Some index files failed to download. They have been ignored, or old ones used instead.


    apt-get upgrade install all updates


    How can I solve this problem?

  • Slow copy from/to NAS

    Got new information:


    Roday I installed new PC with Windows 7 PRO
    Now is installed basic Windows 7 Pro with SP1 and basic SW (audio, video player, antivirus, Chrome, burning SW, PDF reader) and speeds are good (around 80MB/s in doth directions)


    Now I tried to update Windows and check speed from/to OMV
    I think the problem is in Windows updates....

  • Slow copy from/to NAS

    Extra options are empty and logging is off. But speed is still slow... Can it be faulty switch (different speeds UL/DL)? Tommorow I test another switch, maybe cable...
