    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. I have hardware RAID controller there, LSI MegaRAID. 6 slots. My...

    Solved OpenZFS: peculiarity with a labelled cache device and an unexpected label

    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. Question Now, is there any way for the pool to begin using the label without loss of content of L2ARC? I assume that either...

    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...

    Solved Encrypted & Mirrored ZFS vdevs Stopped Booting After Resilvering

    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. Since sysutils/gpart is used in handbook, it seems FreeBSD prefer it than other tools. So, I'd like to know what's the difference and I'd like to make sure the commands I used...

    Has anyone installed 13.0-RELEASE on a RPI 4 with ZFS

    I would like to put 13.0-RELEASE on a RPI 4 4GB, using ZFS. I've previously installed it successfully using the img file, which comes with UFS, and that worked fine. I now would like to try ZFS for familiarising myself with ZFS. I followed this Reddit comment to a post I made on how to...

    Solved Relocating zroot to new disks

    I want to completely replace my existing zroot which was configured by the FreeBSD installer as a ZFS mirror on ada0p3 and ada1p3. The new zroot is to be installed as a mirror on ada2p3 and ada3p3. Adding ada2p3 and ada3p3 as additional mirrors to the zroot pool, and removing ada0p3 and...

    Dear All, looking for some info to tuning and extend the life of my SSD disks I couldn't find any valuable information. The documentation reports: None of these make sense for me. My knowledge of FreeBSD is still very limited and my knowledge of ZFS is even narrower. On Linux I can...

    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...

    Booting From an Alternate Disk in a Mirrored ZFS Root Pool

    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...

    ZFS ZFS basic questions

    Hi Everyone, I've started to use ZFS instead of the venerable UFS and would like to clarify some points about vdevs and zpools. My understanding is that the primary purpose of vdevs is to allow the combination of several disks to be used as a single virtual disk, and the primary purpose of...
