Re: What is the best way to move a VM to a bigger image?
Hello everyone, And now the conclusion. I indeed ran the installer to get partitioned disk easily and the result was just the bsd and base file set installed system. That system worked fine. Then I dumped and restored the partitions or filesystem as FAQ instructs. Anyway I got sha256 identical systems except /dev, /tmp and /etc/fstab The comparison was interesting. $ find / -type f >/tmp/files.txt $ wc /tmp/files.txt 10 100572 5291532 /tmp/files.txt That was weird. No-one should have exactly 100k files in their system. I don't understand why during startup all programs just dumped core. I would suspect some library randomization. After re-installing bsd and base fileset again the new disk booted nicely. I believe relinking the kernel and other end of installation steps would probably be enough to fix that kind of problem. So that was my way of doing this operation. Best regards, Hannu Vuolasaho

Or is there a better way to do it? It's fine, but I took it a different route recently, for a VM that I've been using for a year or two but realized I needed more space. It wasn't that hard to resize. However, it is worth calling out that recreating a VM can be a good way to find out what you need, and don't need, on it. If you go for the resize, you'll need the qemu-img tool from the qemu package in order to make sure the disk image is in qcow2 format (you can convert from a raw image if necessary), and then change its size. From there you can do partition and filesystem manipulation from within the VM. If you need to do something more complicated than add filesystems or grow the last partition, you should probably add more disk images or consider starting from a fresh install. Matthew

Or is there a better way to do it? Not enough information to give an absolute answer, but on minimal thought, I can think of a few ways to deal with a space problem on a VM: 0) Just start over * Advantage: Disk space probably wasn't your only error in setup. Good time to fix those other issues, too. Practice in config. * Disadvantage: Opportunity to make NEW errors! :) 1) build a new VM, restore from your backup to the new VM. * Advantage: tests your backup and restoration process. If your routine backup/restore process doesn't get you through this, you have a problem. You still have your old VM untouched. * Disadvantage: More or less end up with where you started, but more space. 2) Add additional virtual disks to your VM. Copy partitions to new disk, delete partitions on old disk, growfs partitions on old disk to use space of partitions, etc. * Advantage: you really learn disk manipulation, can sometimes be done with minimal downtime. * Disadvantage: you can really screw stuff up, too, leading to option #0 2a) Enlarge the existing virtual disk, use the additional space as with option #2 above. 3) Dang, I thought I had another option here, but I'm blanking on what it was. Advantage: someone else can put their thoughts in. Disadvantage: do you really want to trust someone this forgetful? Nick.
