November 16, 20178 yr I am on day 2 of my trial exploring unraid! I don't have enough spare real disks for testing, so I am testing unraid in a KVM with several qcow based disks. It seems to be working fine for testing purposes. I'd like some advice on (a) migrating existing VM's and (b) best use of my existing storage devices. My current setup is a single host with Samba, NFS, MySQL, libvirt and syslog server. Running 6 KVM guests. No exotic configs, all basic servers. One has a single USB passthrough device and no PCI passthrough in use, at the moment. These VM's make use of the host's NFS exports and mysql server wherever possible. I am considering migrating services to Docker to reduce the number of VM's and hopefully free up resources, perhaps for a more demanding desktop VM with passthrough. However, I'm as yet unfamiliar with Docker. But unraid looks ideal for this type of mixed set up. Currently I have assorted disks, no redundancy. I do have a fairly reliable rsnapshot based backup. Though I currently omit some media from these backups (CCTV and recorded TV each currently with their own dedicated real disk in KVM's). I can afford to lose the data on these if juggling disks to install unraid dictates it. Storage available is: HDD: 1x 3TB, 3x 1TB, SSD: 1x 250GB. AIUI all the disks added to unraid will be zeroed first. Initially, I will make do without a parity drive, since I would lose 50% of my current storage space (the single 3TB drive). AIUI I can introduce a parity drive at a later date. I intend to use the 250GB SSD as a cache and as the sole storage locaton for virtual disks. i.e. no copying. Given the intended usage, I'd appreciate any tips for organising disks, importing existing KVMs and choosing a location for their disk images. Many Thanks.
