I have 3 cheap consumer SSDs on hands and all of them reporting 512b sector size physical and logical.
And this is confuses me.
So I wonder, should I actually create ZFS pools on them with 512b sector size? Or I still should go with 4k?
I have real zpool with files, but want to test firstly.
I created simple zpool with files:
# zpool status -v

I have old small 16GB SSD and now I got better 128GB Samsung 850 pro SSD. Copying stuff to new one is easy with dd, but what block size I should use with it?
I not sure what to do with old 16GB SSD, maybe it is good place for swap? 16GB SSD is ada0 and 128GB ada1.

my 3 disk raidz was lost during a system reboot happend a few days ago. Since then I cant import the zpool and even zdb -e <pool> runs into a kernel Oops.
A simple zpool import shows the pool and no error. so should be importable but isnt.
How can I get the pool at least imported for...
I have a pool as Raid10 with 10 TB capacity,
I want present a zvol for Esxi as Datastore,

For a NAS, the question is UFS or ZFS for main drive ?
I'm thinking about 2 options, which one would you recommend ?
It is a recent hardware, Intel i3. 8Go.
Main drive is an old 1To classical HDD while the 4 other one are new 4To 'NAS' HDD of 2 different brands.
Option 1 full ZFS...

I've got a FreeBSD installation on my VPS, it uses ZFS as its file system. At the end of last year I wanted to clone it onto a local VirtualBox VM, so I did something like the following:

# zfs send -R zroot@2018-11-06 | gzip | ssh my.home.system "cat >...
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...

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...

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:

Many people, perhaps most, setup swap when they setup ZFS. But have any of you actually put it to the...
