Crucial SSDs are not as reported to be good. Two crucial SSDs (BX@150GB & MX@1GB) have failed within the space of two months and they have been purchased and used for 1.5years.
They won't show glaring errors. I only saw 2.45MB checksum error in the last failed SSD. I needed to change the drive...
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 have a Samsung SSD, which freezes Windows with CrystalDiskMark random 4k Q8T8 test. I'd like to run the same test on FreeBSD, but I haven't found any real solution yet. It is possible on Linux with FIO, but it lacks the libaio engine when I install it from ports. In theory it is possible to...
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...
I'm a beginner and trying to install FreeBSD for some time now, but I'm having problems with my FreeBSD installation on SSD and with setting disk speed in general. I hope someone has the time to see what's going wrong here, all input is very much appreciated!
Everything works fine on...
Finding myself at a crossroad.
Need to transfer my home files to a new zpool with bigger drives but not sure if I should get smaller but more cost-effective HDD and wait for SSD prices to drop in the next 5 years or so, OR should I get bigger and costlier HDD for future-proofing...
Please help to solve the problem:
1) I have running desktop system with ZFS mirror, SDDM login manager and MATE desktop;
2) I have also some SSD drives connected the the system and now I tried to move /tmp from ZFS to one of the SSD partitions;
3) to do that I created the UFS partition on...
I'm contemplating the idea of a replacement for my currently hosted 1U server. This server holds 4x 3.5" HDD and 1x 2.5" SSD, with this topology:
- first zpool ZRAID1 mirror 2x 1To + SSD L2ARC
- second zpool ZRAID1 mirror 2x 2To
My ideal next server would have 8x 2.5" SATA slots, and 1x...
I want to use a disk with ZFS and I want to use the best practices...
Both for an SSD and for an HDD
Delete the disk
# gpart destroy -F da0
# dd if=/dev/zero of=/dev/da0 bs=1m count=128
Prepare the disk
# gpart create -s GPT da0
# gpart add -t freebsd-zfs -l storage -a 1M da0...
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 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 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.
Geom name: ada0...
Hi everyone! Few days ago I bought a new Samsung 860 EVO 250GB SSD and reinstalled FreeBSD 11.2-Release in it. But prior to installing FreeBSD, I first checked this brand new SSD on my Windows machine. I used the Samsung Magician and 2 other applications to test it and it passed with flying...
Currently FreeBSD has some bug with NVMe drives.
As I gather information about this issue, I'd like to share a comprehensive list of SSDs.
- Ones that reportedly work
Samsung 950 PRO
It is a new install on an old IBM tower server. I have played with 10.x 32 and 64 bit on it before but this is 64bit 11.1. I think there is an issue with a hard disk but it seems inconsistent.
The server is an IBM 84852AU 206m. The boot drive is a SATA 64GB ssd taken from and HP proliant...
I am experiencing problems with one of two Intel SSD since approx
July 2017. Reformatting the disc improved the situation for a while,
currently the disc is rejected during boot.
2 x SSD: INTEL SSDSC2BW480A4 DC32
Intel Patsburg AHCI SATA controller
The disk is part of a ZFS mirror:
Server intel NVME drives.
nvd0: <INTEL SSDPE2MX450G7> NVMe namespace
nvd0: 429247MB (879097968 512 byte sectors)
nvd1: <INTEL SSDPE2MX450G7> NVMe namespace
nvd1: 429247MB (879097968 512 byte sectors)
How do I split the disk correctly?
To split a SSD drive with a 4 offset?
I briefly looked at the net for information about SSDs (Solid State Drives) and freeBSD and found only confusing articles on the subject. Obviously it is not the fault of the authors it's just that I am not well versed on hardware.
Anyway I decided to put my queries here as I have a project on...
Hello. I have a server with only 3 SSD, I want to run only PostgreSQL on it. But I don't have idea what options of ZFS to use for best performance. Did anyone here such a setup, and can give me a hint?
