  • Replacing a system disk in Open Media Vault

    Fortunately Open Media Vault, OMV, emails warnings when disks are failing. This is also true for the system disk. I have been getting warnings my old system disk is failing and this is what I did to fix it. First shutdown the PC and disconnect the RAID disks – just to ensure you don’t do… read more…

  • Scheduling a task in Open Media Vault

    I need to run some scripts every night to move some files around in OMV. I want something that simple and easy to maintain and more or less stock standard. There are probably many variations on how this could be done but this is how I chose to do it. Before we start it is… read more…

  • DNS problems, email notifications not being sent

    I had a working Open Media Vault system with notifications going out and then it stopped. OMV runs on Debian. In the log I started seeing: The actual error was: postfix/error[1443]: 1D96741676: to=<joe.blogs@domain.com>, relay=none, delay=175894, delays=175853/41/0/0.24, dsn=4.4.3, status=deferred (delivery temporarily suspended: Host or domain name not found.

    I am setting up an Open Media Vault, OMV, NAS box for my home storage requirements, detailed in the post Installing Open Media Vault. I don’t have the resources to setup a full RAID 5 array, this would require a box with space for 3 drives plus which I would actually need to purchase 3… read more…

  • Installing Open Media Vault

    OMV doesn’t have a backup function which is a problem. Given it is relatively straight forward to setup OMV one option is to simply set it up again. I really don’t want to do that so the only other comprehensive option is to backup the system disk. The problem is that there isn’t any free,… read more…

  • Wipe a RAID disk

    If for some reason you have a disk which used to be in a software RAID and you need to add it back into OMV then OMV will still recognize it as a RAID disk, even if you have reformatted it. In my case I had a disk that was removed from the array for… read more…

  • Create a Debian Live USB flash drive

    There are many sites that describe how to do this, but some techniques just didn’t work for me and many required you to do it from Linux which also doesn’t work for me. This is what worked for me on Windows 10. 1. Insert you key into your Windows PC 2. Though this may not… read more…
