I created raidz with labels and geoms /dev/ada1pX /dev/ada2pX /dev/ada3pX /dev/ada3pX as well as /dev/gpt/$labels existed before reboot. It was like this: pool: hddPool_x3_RAIDZ state: ONLINE config: NAME STATE READ WRITE CKSUM...

It wasn't clear to me on the installer how I would Raid-1 3 sets of drives and then Raid-0 those 3 sets. Basically 2 x Raid-1 2x Raid-1 2x Raid-1 And Raid-0 the 3 logical drives. I hope I have explained well what I am looking at doing. If this is not something that can be done from the...

Guys I changed my disks in my T430 to make a better backup routine. Before I had a strip with 3 ssd's with 1 tb each. I changed to root in a 240gb, home in a 1tb, and I left 1tb for dual booting with OBSD. And the last 1tb I took out of the note and put it in a case for external use. Everything...

Last week I experienced a major problem after upgrading packages to the latest quarterly which I couldn't even resolve by reverting to an earlier boot environment so I decided to restore the entire system from my backups. The zfs pool for my system is normally a mirror with two drives. As a...

I have a desktop that has a 512 GB NVMe SSD. I am planning to repurpose the desktop as a file server by adding two 10 TB hard disks, and installing FreeBSD with ZFS on those two 10 TB hard disks (RAID 1, i.e. two disk mirror). It seems that I no longer have any use for the 512 GB SSD in this...

I set up a Samba server with samba413 last week, but recently it has been having a strange error. It is unable to connect to a directory in a zpool that has permissions 777. The smbd is also currently running as root. I tried reinstalling and switching from samba413 to samba416 to no avail...

Hi. OS 13.1, Raidz1 on 4 disks for video surveillance data. ~8tb of mp4 files. No snapshots. Recently i'v rewrited all of this data with something like this: ffmpeg -i old.file.mp4 new.file.mp4 mv new.file.mp4 old.file.mp4 After that ~2T of space on this pool disappeared. How i can fix this...

Hi, When on certain pools or datasets large files will be stored, it can be an advantage to use a larger recordsize of 1M in ZFS. Suppose the pool is encrypted by GELI, would it be better or worse to align the sectorsize of GELI with the recordsize of ZFS? In general i see GELI sectorsizes of...

Hi everyone, I created a new ZFS dataset root@vieron:~ # zfs create zroot/playground root@vieron:~ # ls -ld /zroot/playground/ drwxr-xr-x 2 root wheel 2 Mar 17 12:40 /zroot/playground/ and assigned read and write permissions to the "labgroup" group root@vieron:~ # chmod 775...

Hello everyone, I wanted to share an article that I recently wrote about migrating from Proxmox to FreeBSD's bhyve hypervisor. The article covers the process of migrating virtual machines, storage, and networking from Proxmox to bhyve, and includes tips and tricks that I learned along the way...

Hi, I have set up zfs send | zfs recv replication as an unprivileged user. The purpose is to have an off-site backup process that is a) fast, and b) secure, in the sense that a successful cryptolocker attack on the primary backup would be partitioned off by the dint of append-only replication...

I have the GELI key, but the associated pool (HDDs) unavailable currently (phisically). Can I check my password(s) with the keyfile only, without the encrypted media? If I know, the keyfile contains the keychain(s), protected by password(s). I would like to check this password, but without...

I am dual booting NixOS in the same zfs pool with FreeBSD. What would be the best way to export the root pool during shutdown automatically?

Hi! First of all, I am complete newbie in FreeBSD. I would like to install FreeBSD on ZFS. Modern installer have everything to install FreeBSD on ZFS without any problems, but I have a one "Ideafix", if you know what I mean. I want to remove Boot and Swap partitions from ZFS pool(RAIDZ1) and...

Hi All. I got a system problem since FreeBSD 13 as follows (Prior 12, I have no impression about the issue). Jan 30 11:22:47 test kernel: [116123] pid 50340 (mysqld), jid 1, uid 88, was killed: a thread waited too long to allocate a page Jan 30 11:22:47 test kernel: [116134] pid 32665...

Hi, I want to learn about how exactly boot process of FreeBSD 13.1 with GELI + ZFS on Root on UEFI works. I read about loader, UEFI, geli and, still I can not understand it. Also I have some more specific questions too: I have two partitions. EFI and ZFS. The whole root filesystem is in ZFS...

Hi, On this forum and on internet many things are found about GELI. What I was looking for is: - That GELI boots from the local disks on the machine - It works with a passphrase and a keyfile. - The keyfile is located on a USB I have the impression this setup is not possible, but I want to...

I currently have a system with 12x 5TB 2.5" HDDs. Due to a batch of cheap/faulty SATA cables, one of these drives failed hard (and was replaced), and a couple of the drives are now showing bad sectors. I've replaced the cables and the system is a lot more stable, but since I'll inevitably have...
