    Migrate VM ZVOL From One Pool To Another

    Edit: I saw someone mention in another thread that a simple dd if=/dev/zvol/storage/virtual_machines/Arch_Linux-hfs0ap of=/dev/zvol/flash/virtual_machines/Arch_Linux-hfs0ap should work and it does, one caveat is that you need to first create the zvol in the other pool before you start dd...

    Moving a zvol

    Hi I have a couple of Linux VM's and I believe the drives their zvols are stored on may be failing. These are SSD and they pass all the regular SMART based read tests so write tests will be needed in order to verify that they still work. However I was wondering how I can move the zvol's to...

    Can someone test zvol expansion with iSCSI?

    In 11.1U6 if you expand a zvol that is presented as an iSCSI LUN, the new size is not reported until the iSCSI (ctld) service is restarted. Can anyone confirm if this is still the case for 11.2? I know I could test this in a VM but I'm lazy/busy/either.
