    ZFS ZFS on hardware RAID

    Hello, I used Centos for 10 years on a particular server. Now as Centos 8 gone, I would like to switch to FreeBSD instead of Linux (no particular reason, I might just use Debian though, but I like FreeBSD). Now the doubt is here.

    At some point in time, my pool named Transcend began using a device reference instead of the previously specified label – gpt/cache-transcend – for its one cache device.

    ZFS GELI vs ZFS encrypted dataset

    I've been using ZFS encrypted datasets pretty much since the first day of availability. On this forum and also the mailing lists I see a lot of people running ZFS "on top of" GELI. I'd like to ask: Is that usually more of a legacy thing or are there situations where one would prefer ZFS on GELI...

    I had a setup with 4x4 TB disks, with two mirrors consisting of two disks each, giving me about 8 TB of usable storage space. One mirror consists of ada0 & ada2, the other mirror of ada1 & ada3. I needed to upgrade storage space, so I decided to upgrade one mirror by resilvering two times. I...

    ZFS What is the difference between gpart and other tools?

    I'm trying to format my external disk with ZFS filesystem. I've search and found several guides using different tools.

    Solved When does it make more sense to use multiple vdevs in a ZFS pool?

    I know for one thing that if the primary concern were protection against disk failures, raidz3 would be the way to go. In such a scenario, If I had 7 disks, I would create a pool like this: pool: tank state: ONLINE scan: none requested config: NAME STATE READ WRITE...

    Following this guide I created a mirror disk for my zroot. So, I decided to disconnect the main zroot disk to see if the other one was booting (I installed the bootcode on the disc). When the system boot, ZFS cannot boot the mirrored disk and display just a series of writing errors as : ZFS...
