I followed below without resizing/stretching the initial partition1. After booting into redsleeve and yum update I took out the SD card and I resized partition1 with fdisk on my laptop. I rebooted on dreamplug with pre-mount option and tried to stretch it with zpool command. I couldn’t start zfs-fuse, nor use zpool command.
However, after booting again normally, I could see the expected partition (enlarged) size. Is it possible that the stretching could have taken place automatically during the booting? > On Oct 30, 2015, at 7:15 PM, Gordan Bobic <[email protected]> wrote: > > OK, guys, this is what I suspect some of you have been waiting for: > > https://www.mirrorservice.org/sites/ftp.redsleeve.org/pub/el7/images/ > > Assumptions: > 1) DreamPlug: use internal uSD card > 2) SheevaPlug: use USB attached storage (otherwise change /dev/sda > in /etc/fstab to /dev/mmcblk0) > 3) GuruPlug: Not 100% sure, but one of either 1) or 2) will be > appropriate depending on how the > device you want to do appears in /dev/ > 4) On the staging machine the SD slot appears as /dev/mmcblk0 - double > check this to avoid the risk of clobbering the wrong device! > > Process (assuming the target is the DreamPlug: > > 1) Update your *Plug's u-boot as per the instructions here: > http://www.cyrius.com/debian/kirkwood/sheevaplug/uboot-upgrade/ > > Make sure you note down your MAC addresses before you reflash u-boot, > and re-set them afterwards! > > > 2) Download the image and extract it to a uSD card (/dev/mmcblk0 on the > staging machine) > wget -O - > https://www.mirrorservice.org/sites/ftp.redsleeve.org/pub/el7/images/kirkwood.img.xz > | xz -cd > /dev/mmcblk0 > > 3) Re-partition (MBR format, use fdisk) the target device to stretch > the root partition to take up all of the device.
