    Is this correctly configured?

    Hi All, I'm a FreeNAS newb, but have spent many hours poking around on it.... its starting to play nice. Anyways, I just checked my Volume Status and wanted to get someone with more experience to confirm if this is indeed a RAID10 or Striped Mirrors in ZFS Terminology. I have an SSD drive as...

    Noobie here, planning 1st time build with existing parts

    Hello Noobie here, I've done some reading up on raid and FreeNAS and still have so many questions. I'm an IT network engineer so considered a geek but I've never really dug into building raid before. My plan was to rebuild my unused Windows 10 home built desktop into a FreeNAS, as its only...

    SOLVED How to create striped mirrors aka RAID10 in the GUI?

    I have six 3 TB drives and I would like to create 3 striped mirrors with 2 drives in each mirror - RAID10. The wording in the manual and the GUI are confusing and not very detailed. Googling and searching the forum for the past couple of hours haven't helped me much. What is the difference...

    Degraded RAID-10 Array

    I have been running FreeNAS 9.10 containing a RAID10 volume comprised of six 3TiB WD datacenter drives for about a year now. A few days ago I saw that one of the mirrors had degraded causing the array to degrade. So I added a new 7th disk and instructed freenas through the GUI to replace the...

    Striped mirrors not setup correctly

    I have a FreeNAS Mini (4x HDD) with 4x 3TB drives. It's supposed to be setup as a RAID 0/1 striped mirror: 1 mirror extended by 1 mirror. I'd expect this to show roughly 6TB of disk space, but it shows 3TB leading me to believe the second mirror is a mirror of the first instead of an extension...

    FreeNAS SSD iSCSI not performing as expected

    I'm looking at using FreeNAS to act as the iSCSI storage in a large QEMU/KVM environment. The idea is to find a build that works really well, and add identical SANs to the environment as it grows. I just assembled the first prototype and am concerned with the initial performance tests. Let's...

    112 TB Server with only 32GB of RAM?

    I have replaced ten of the fourteen 4tb drives in my array with 8tb drives. My server always seems stable and fast to me, but I notice that I am considerably out of step with the 1 GB per 1 TB guideline. The problem is that my motherboard is maxed out at 32GB of RAM. Should I complete my...

    SOLVED Demo FreeNAS RAID10 ZFS Pool failed drives and upgrade drives experiments

    Hey guys, checkout my cool video which I did with my FreeNAS setup. I did a setup with 8-drives configured in RAID10 ZFS pool. And I did multiple iterations of failed drives and upgrade drives scenario. Since it is RAID-level10, to speed-up my demo I did removal/replacement of 2-drives each...
