    ZFS Undo offlining of a RAIDZ1 drive (without rebuild)?

    I run an old HP N40L XigmaNAS box with a RAIDZ1 consisting of 3 WD Red 4TB drives. The ada1 drive showed some SMART errors, so I decided to replace that drive. Setting the drive offline, the pool showed the status "DEGRADED" as expected. But after shutting down the system and replacing that...

    ZFS Performance: RAIDz1 vs mirroring

    In my home PC, one of my two HDD that I have in (btrfs) RAID 0 failed. So, I am shopping for the replacement. I am planning to install FreeBSD (zfs) and set up RAIDZ (buying 3 SSDs). Now, I am reading everywhere that mirroring 2 disks (1 vdev per disk) is faster than RAIDz1 with 3 disks. And it...

    ZFS Migration from RAIDZ1 to RAIDZ2; is it possible?

    I've tried some basic searches for this. I haven't found a concrete answer. What I want to be able to do is do a base install as RAIDZ1 then drop another identical drive in and convert or resilver the array to a RAIDZ2. Feasible or fool's journey? If it's feasible; how do you do it? ZFS...

    ZFS Replacing entire pool?

    I would like to replace all 3 spinning drives of a raidz pool with (smaller) SSDs: the smaller SSDs will still be more than adequate for my storage needs, and should be significantly faster. The system has a limited number of SATA ports (4): 1 is in use for the system drive (which is already an...
