  • Migrate to new drives / replace all existing drives

    Hi OMV-Community,


    over the last years I learned through OMV a lot of Linux, storage and self hosting topics and I am loving it!

    Recently I encountered a spin down problem and figured out, I am using SMR drives for my main RAID 5 Storage. I have heard a lot about SMR and the issue when rebuilding a Raid. Even tough I am doing regular backups, it seems quite risky to me.

    This is why I wanna/must replace all 4 drives of my RAID-5 array. With this task I also want to extend the capacity of my drives. Currently I have 9 TB of data used (1,7 TB user data + 7,3 media data).


    What steps do I have to do, to migrate my raided data from the old SMR-raid to my new drives?

    How can I ensure all SMB-users and docker-applications can access the data on the new drives?

    Do you have any other tips regarding this topic? ;)


    Thanks in advance and have a nice day!

    Regards, Max

  • HDD spin down stopped working

    Hi there,


    I noticed that HDD spin down stopped working a while ago. Unfortunately I didn't find a solution to fix it...

    Spin down is really important to me, because 90% of the time I am not using my HDDs. This way I can save power and life of them.


    Short explanation of my OMV server:

    - HDDs (4x) are in a OS Raid 5 and used for mass storage

    - HDDs are connected via SATA to the mainboard

    - SSDs for OS and most Docker containers

    - Spin down worked for years


    Solutions I tried fixing the spin down problem:

    - Checking the SMART "Power mode" (Storage --> SMART): Is set to "Standby"

    - Checking the spin down time (Storage --> Disks): Is set to "20 minutes"

    - "Advanced Power Management"-Setting (Storage --> Disks): Trying both 127 and 255 (it worked with 127 before)


    When I manually spin down the HDDs with sudo hdparm -y /dev/{sda,sdb,sdc,sde} the drives spin up a couple seconds after.

    I also see the HDD activity LED blinking every 30 seconds or so.


    Do you guys have any ideas how I can fix this problem?

    I think some process/container is using the HDDs/RAID every now and then.

    --> Is there a way to see what process/container is using the HDDs/RAID?



    Thanks in advance and have a great day.

  • apt-get update error (Release file missing, repository can't be authenticated)

    Hi,


    I have several problems regarding updates and installing applications on my server.


    Today I wanted to do some updates on my server when I encountered some errors.
    First I tried it via the webinterface. When I hit "check" to check for updates under the update-panel I got an error message (see "webinterface error message.txt" in attachments webinterface error message.txt ).


    Since that didn't work I tried it via the CLI using "sudo apt-get update". When doing that I also got an big error message. (see "CLI error message.txt" in attachments CLI error message.txt ).



    I am not sure what could have caused this and how to fix it.
    Some weeks ago I had also trouble with pulling stuff from hub.docker.com due to some certificate issues. But that problem is now fixed.


    Thank you in advance.
    Regards,
    Max
