I'm a new FreeBSD user,
I recently installed FreeBSD 13.2p8 on an old Thinkpad T400 laptop with a "Samsung 850 EVO" SSD,
I found the following lines in my dmesg:
ada0 at ahcich0 bus 0 scbus0 target 0 lun 0
ada0: <Samsung SSD 850 EVO 500GB EMxxxxxx> ACS-2 ATA SATA 3.x device...
As one may know NFS version 4.2 supports discards (trim). It was acknowledged to work on many Linux distros - RHEL 7, Opensuse 15, ovios etc.
In FreeBSD version 13 (13.1 in my case) we also have NFS server ver 4.2 but discards doesn't work.
Is it a bug or?
p.s. I'm not the only one...
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...
As "FreeBSD 12.2-RELEASE Release Notes" shows:
Does this only support FreeBSD guests?
On the following guests with virtio-blk+zvol backends, I tested whether the free space can be reclaimed automatically after deleting some files:
1. FreeBSD 12.2R UFS: Yes
2. FreeBSD 12.2R ZFS: Yes
I would like to create a striped RAID-0 made up of four NVMe SSDs. It's for unimportant temporary data, but I need the space and lots of speed would be nice to have as well, so I'd like to use RAID-0 rather than something like JBOD/CONCAT. I would not like to use ZFS, but UFS for a file system...
I am planning to do a bare-metal installation of FreeBSD 12.1 on a intel 330 SSD which already contain Devuan 3.0 Linux on UEFI-GPT system. I'm planning to install Gnome 3. I tried running the installer and manual mode in bsdinstall seems to me, confusing. It is asking for entire disk or...
The problem is this. As you know, the essence of TRIM is to clean up blocks that are no longer needed by the file system in the background, or with minimal impact on performance. On my own system, the picture is as follows. We create a file of 2 GB in size, delete it, and the disk spends all its...
I have this exact issue,
I have virtual machines (FTP, WEB, MySQL servers) on KVM sometime ago it was filled with some files or sites that are no...
I'm new to FreeBSD
Currently I have some FreeBSD (ZFS) VMs running great on KVM.
This VMs were virt-sparsified or thin-provisioned, however, in time, there were some GB files in and out
###This is the current size of my FreeBSD VM

I have a zfs pool encrypted with geli. After a clean system boot, I mount the geli devices, then do zfs status tank so the pool is discovered. The system panics. I found and old thread documenting a similar issue (involving SSDs and GELI), but it still seems to be happening. Here's my stack...
I’ve never been in a server room from which I could not steal a random hard drive without getting caught, if I wanted. I have been in server hosting companies’ rooms in more than one countries.
Should I find one that employs guards with machine guns, still there is a point from which it isn’t...
Recently I bought one, and while playing with reinstalling distributions I wonder if I can TRIM the entire SSD using Live tools? Or I am mistaking something?
EDIT: To make it clean and faster. Again, am I missing something?
recently, me as a noob got one experts opinion on (not) using TRIM.
Since this is the only voice I know recommending not to use TRIM,
I'd like to put it here and hopefully get your valued opinion on this topic.
Also I'd like to know, why TRIM has the potential to corrupt the...
