  • Setting up Rsync

    Post

    I wouldn't bother backing up the PLEX metadata folders. Instead make sure that the video files are backed up. In case all of the plexmediaserver files are lost plex can be reinstalled easily and automatically update and download the metadata again. But most likely the actual media files are not as easy to replace. If you want FULL backups then you most likely have to stop everything running on the nas. The easiest way is to boot from some other media and mount the drives and backup that way. Als…

  • There is no should. Whatever works is OK. Most likely the most efficient way to copy the files would be if both HDDs are connected to the same Linux computer over SATA. But if you are not in a hurry then you can most likely do the transfer over the network or with one or both HDDs connected using USB. Even over USB 2. Linux computers can read and write windows filesystems. But it is much more difficult for a windows computer to read a Linux file system. It is like the Americans or British speaki…

  • You need to provide more information. What types of "files"? How are the files updated? From where are the files updated? How are the files accessed? How are the sites connected? Why not just use a central cloud solution?

  • This is a great opportunity for you to test your backup system. Just pretend that the old drives died and restore to the new drives. What does it matter if you loose links to old paths? Just use the new paths. KISS! Install to the new system partition then restore the data. Fix new backup scripts/routines. Done!

  • Different Micro sd size

    Read only allocated partition should do it. But I don't use Windows, so I can't test it. I remove the SD card and use a Linux Laptop with a SD card reader to back it up. I use a script, and dd and partclone. It only copies the partitions. There are other tools that do the same. I agree it would have been great if you could backup/restore the rootfs from OMV. See: New to OMV and Linux

  • I've never figured out how to fix this. I just restore a working backup of the rootfs to the SD card and carry on. This happened to me a lot because my HDDs are incompatible with hdparm and activating ANY of the physical disk properties caused them to unmount and fail to mount on reboot. Now I stay away from enabling any of the physical disk properties, and OMV works fine. Also I reflashed the SATA firmware. Se recent posts. YMMV.

    OMV doesn't expand the rootfs to fill the available space. Only to 7-8GB. So it should work perfectly to restore the rootfs from a 32GB card to a 16GB card or the other way around, if you don't manually resize the rootfs. I do this, and it works fine. Just make sure to use a tool that doesn't image the whole card, but only the actual partitions.

    Yes that looks right. Everything disabled. But it should be "/dev/sda" not "/ dev / sda". I assume that the firmware update fails otherwise? You should get: "Programming & Compare Success!!" response if the update was successful. You have to power cycle after successfully updating the firmware. A reboot is not enough. Pull the power plug and wait a few seconds before reinserting it again. The drive should now spin down after 30 minutes. However you need to make sure that you don't run any softwa…

  • OK. If it was a physical partition on a physical drive, then this would be easy, just boot from another partition on another drive and install and run for instance parted to resize the partition. Or gparted if it is a full Linux desktop system. But since it is a partition on a virtual drive I suspect it is not that easy to access the partition on the virtual drive. You may need to use some VMware tool or utility to resize the partition inside the virtual drive while the VM is not running.

  • If space runs out on the root filesystem OMV will crash. If you have some software that store data in the root filesystem you can move that data to the data partition and link to the original place in the rootfs. Or mount another partition in the rootfs. Either is good practice to avoid any catastrophic problems with a full rootfs. Also it makes backups of the rootfs smaller and faster to do. I do this for Emby, for instance. OMV automatically resizes the rootfs on first run. Typically expanding…

    wiki.odroid.com/odroid-xu4/app…requtils_cpufreq_govornor I don't run S. M. A. R. T. other than manually from the GUI. I used it initially only to get HDD temperatures to ensure that the HDDs didn't run too hot. I had problems with the cooling, but I fixed it with a ultra low noise Noctua A12x25 FLX fan for all five HC2s.

    Also I underclocked four of my HC2 to 1400 MHz because they are still able to saturate GbE and I only use them as file servers. That makes the HC2s run cooler with less power. One HC2 runs full speed. It is the one with a SSD and on which I run Emby, LMS and some other software. I updated the SATA firmware on all 5, and set spin down to 30 minutes on all of them.

    Yes. I set it to 30 minutes when I updated the firmware to SATA. You can set it to whatever you want, as long as it is 3 minutes or longer. See example 4 in the link above. It works fine without hdparm settings in physical disk properties. When I tried the physical disk properties the HDD was permanently unmounted after the first spindown and would not mount on reboot.

    I use 12TB IronWolves with two of my hc2. I updated SATA and disabled all physical disk properties. Disk->edit. Otherwise OMV quickly dropped/unmounted them. When I updated SATA I also set spindown to 30 minuters. Now my IronWolves seem happy... wiki.odroid.com/odroid-xu4/software/jms578_fw_update

  • Built-in backup fails

    Post

    Don't backup /tmp. It is very difficult to correctly fully backup a live root filesystem. The best way may be to boot from other media and run a backup on the filesystem when it is not live. It would be great if OMV added some functionality so that you can set a flag somewhere and reboot. And during the reboot a clean full snapshot of the root filesystem is created. Or restored.

  • Rsnapshot needs to much space on target

    It is difficult to figure out the actual size of rsync snapshots. The reason is that several snapshots may share copies of the same file, if the file didn't change between snapshots. That is why you use rsync snapshots. But the snapshots looks as if they each have a separate full copy of the whole file system. The best way to estimate the size may be to look at free space left on the filesystem and compare that to total space on the filesystem. Some filesystems don't support hard links that rsyn…
