zfs

(Disclaimer: I'm a noob. Structure your replies accordingly.) I installed FreeBSD 13.0-RELEASE last fall with the help of this forum. I haven't updated the computer since then, and have basically just ensured that, with my current install, the OS and KDE work and I am able to use Firefox...

Hello, I used Centos for 10 years on a particular server. Now as Centos 8 gone, I would like to switch to FreeBSD instead of Linux (no particular reason, I might just use Debian though, but I like FreeBSD). Now the doubt is here. I have hardware RAID controller there, LSI MegaRAID. 6 slots. My...

At some point in time, my pool named Transcend began using a device reference instead of the previously specified label – gpt/cache-transcend – for its one cache device. Question Now, is there any way for the pool to begin using the label without loss of content of L2ARC? I assume that either...

Hi, Just saw an update on a port in FreeBSD: sysutils/parkverbot . Is there anybody with experience with the port, I wonder if it's really interesting to use? Does it make a difference? Thanks in advance for posting!

I've been using ZFS encrypted datasets pretty much since the first day of availability. On this forum and also the mailing lists I see a lot of people running ZFS "on top of" GELI. I'd like to ask: Is that usually more of a legacy thing or are there situations where one would prefer ZFS on GELI...

I had a setup with 4x4 TB disks, with two mirrors consisting of two disks each, giving me about 8 TB of usable storage space. One mirror consists of ada0 & ada2, the other mirror of ada1 & ada3. I needed to upgrade storage space, so I decided to upgrade one mirror by resilvering two times. I...

I am experimenting with boot environments and observing some very weird behavior related to installing/removing packages via pkg -c /tmp/path/to/be <command>. Any time I attempt to install/remove packages in a non-current boot environment using this incantation and then immediately bectl...

I'm trying to format my external disk with ZFS filesystem. I've search and found several guides using different tools. Since sysutils/gpart is used in handbook, it seems FreeBSD prefer it than other tools. So, I'd like to know what's the difference and I'd like to make sure the commands I used...

The left pane of thunar lists some zfs datasets and not others. I have not find a rule why some are listed and not others. Anyone ?

A dedicated root server at Hetzner running FreeBSD 13.0-RELEASE-p7 with 2 x 512GB NVMe configured as ZFS mirror and a storage box with 100GB offering access by scp / rsync / BorgBackup (but no ssh login). # zfs list NAME USED AVAIL REFER MOUNTPOINT zroot...

Hi ! I'm totally new to BSD (comming from Ubuntu/Debian land), starting an Homelab project with recent refurbished hardware : Optiplex 3080, 8gb ram, core I5 10500T (6 cores / HyperThread Yes). I'm planning something simple with this homelab : - ZFS crypted / Yubikey - Containers ( or a...

I would like to put 13.0-RELEASE on a RPI 4 4GB, using ZFS. I've previously installed it successfully using the img file, which comes with UFS, and that worked fine. I now would like to try ZFS for familiarising myself with ZFS. I followed this Reddit comment to a post I made on how to...

I want to completely replace my existing zroot which was configured by the FreeBSD installer as a ZFS mirror on ada0p3 and ada1p3. The new zroot is to be installed as a mirror on ada2p3 and ada3p3. Adding ada2p3 and ada3p3 as additional mirrors to the zroot pool, and removing ada0p3 and...

Dear All, 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...

Hello, Trivial task. Create backup of system bootable zfs pool with several datasets and then restore it. system: root@:~ # uname -a FreeBSD 13.0-RELEASE FreeBSD 13.0-RELEASE #0 releng/13.0-n244733-ea31abc261f: Fri Apr 9 04:24:09 UTC 2021...

I know for one thing that if the primary concern were protection against disk failures, raidz3 would be the way to go. In such a scenario, If I had 7 disks, I would create a pool like this: pool: tank state: ONLINE scan: none requested config: NAME STATE READ WRITE...

Following this guide I created a mirror disk for my zroot. So, I decided to disconnect the main zroot disk to see if the other one was booting (I installed the bootcode on the disc). When the system boot, ZFS cannot boot the mirrored disk and display just a series of writing errors as : ZFS...

Severl hours ago my zpool suddenly exploded. The server rebooted and could not boot. root@:~ # zdb -AAA -F -d -e iile-boot zdb: can't open 'iile-boot': Integrity check failed root@:~ # zpool import pool: iile-boot id: 4380822407036168996 state: FAULTED status: One or more devices...

sysutils/lsof Background – and so on. Now Good news. Significant improvements ahead: https://github.com/lsof-org/lsof/pull/184 Related FreeBSD bugs include: 253553 – sysutils/lsof: no zfs support on 13 260235 – sysutils/lsof: filenames missing on FreeBSD >= 13, due to namecache field...

Hi Everyone, I've started to use ZFS instead of the venerable UFS and would like to clarify some points about vdevs and zpools. My understanding is that the primary purpose of vdevs is to allow the combination of several disks to be used as a single virtual disk, and the primary purpose of...
