Should you resize root partition on flash?

  • There is the flashmemory plugin which is significantly reducing the writes to the SD card.


    As far as I know it does not matter how large the partition is. The controller of the SD card will level the writes to the complete available flash.

  • Get a mirror?


    Most likely you installed software in a way that means that flash is being used for storage. For instance docker app data with metadata databases for media servers.


    You should create a share on the hard drive and use that instead.


    There should be no need to resize partitions on the SD card. If you feel a need, then you are doing something very wrong. However the worst(?) that can happen, I assume, is only that the card fail prematurely and you may lose all data on the card. You can buy a new card, right?


    Even if you only have a 8 GB partition on a 64-128GB card, that is perfectly fine. Leave the unpartitioned parts unpartitioned. Wear leveling will make use of the whole card.

    Be smart - be lazy. Clone your rootfs. This help is Grateful™.

  • Honest suggestion after having usb key or SD cards dieing: install OMV on the cheapest SSD you can find (64/128GB) and stop worring about it.

    That’s fine if you are using an AMD-64 machine and don’t mind sacrificing a SATA port.

    RAID is NOT a backup and not useful for most home users. Rsync makes true backup and restoration stupid easy, and it's built right in to OMV. Use this command in a Scheduled Job: rsync -av --delete /srv/dev-disk-by-label-NAMEofSOURCEdisk/ /srv/dev-disk-by-label-NAMEofDESTINATIONdisk/

    I have an AMD-64 machine and I didn't sacrifice a SATA port. I put the OMV 2.5in 16GB SSD into an external USB case and plugged into a USB port.
