I'm currently managing a dedicated server with two 3TB hard disks but ZFS seems like a stranger to me. I want something like RAID-1 for data redundancy. In the storage management part, by default, the auto ZFS-on-root wizard utilizes the two whole disks (not partitions) and set up a...
There is two hard drive on the system

Hello, I have an old FreeBSD system (running 9.3-RELEASE) that I would like to update to the latest 12.0. Trying a "live USB" it seems that the new system would work OK. In the current installation I have a specific partitioning scheme on the boot disk (SSD) and several HDDs configured for ZFS...
I have 4 disks in a RAIDZ with geli encryption. I'm currently running FreeNAS 11.2. I'm posting here because their forum doesn't have a great reputation.
One of them has been having issues so I decided to pull it and run a quick test to verify things.
without thinking I decided to offline the...
I use it for development, you know, Programming 'n stuff... :) I also use it for ZFS, since I keep backups of my friends' and family members' data. :) I also use it for other things, like when I use Linux, but want more of a UN*X-y feel. It also speaks to how good of an OS it is when I...
This is my first experience with ZFS.
I have created a raidz2 zfs pool with 5 drives, no spares (I know won't happen again). It's a lab server so no critical data.
The pool became degraded after a HD failure. (showing as FAULTED with too many errors).
Some of data I had...
I need an advise and correct direction to my problem. I am a new FreeBSD user. Our recent Windows 10 machine was hit by a Ransomware and it spread to other machines on Network also.
To protect that in future, I added a new HDD on the system and installed FreeBSD 12.0 x64 using HyperV on it...

I apologize for the naive question, but I couldn't find any answers. I have an image of a ZFS root/boot disk, obtained via dd from the master server. Need to create many identical servers, also with ZFS root/boot. On UFS I'd obviously use dd to do that. Is there any workaround to...
In the past there were some interesting discussions about swap with ZFS, and its performance when a machine actually runs out of memory. These include:
2015 bug report
Many people, perhaps most, setup swap when they setup ZFS. But have any of you actually put it to the...
I am currently running an FreeBSD 11.1-RELEASE and preparing for upgrade (late, I know). The only thing I am worried about is a message "failed to read pad2 area of primary vdev" during the boot process when geli needs the decryption phrase.
I searched the forum here but only found...
Looks like FreeBSD is going to be re-basing ZFS on the Linux port. The original port was based on OpenSolaris/Illumos which then moved to DelphixOS. However, Delphix have now announced they are moving to the Linux port...

Hey guys :D
Is it possible to upgrade disks on a mirrored ZFS-on-root install? If it is possible, then is it risky?
In my case I want to upgrade my 2x 250GB SSD's with 2x 500GB SSD's.
Thanks in advance :)

Good day everyone, I have recently purchased a Dell R320 server with the H310 mini card. This card has a no raid mode where the disks show up individually (AFAIK, it does not create a raid 0 array for each disk). I would like to know if using this mode is safe for ZFS?
BTW, the mini card cannot...
My FreeBSD 11.2 box has the strange behavior that copying a file via NFS, SMB, or AFP is always capped at exactly 60 MByte/s. However, copying the same file to the same client via SCP immediately hits GBit line speed at 110 MByte/s.
It shouldn't be a hardware limitation, I can read the...
I do most of my work on a VirtualBox VM on my work laptop. The VM runs FreeBSD 11.2-RELEASE.
I routinely ZFS snapshot my environment and send those snapshots to a secondary desktop, also running FreeBSD 11.2-RELEASE.
On the desktop they live under:
