gpart

Hello, I had the following partition scheme: ada0: ada0p1 freebsd-boot ada0p2 freebsd-swap ada0p3 freebsd-zfs ada0p3 had a size of ~1TB, and after I resized this partition to 500GB using gpart, the boot loader cannot found my zfs pool. What should I do to fix my boot loader and my zfs pool...

Hi all. Using ZFS raidz quite a lot in my work; I used to give zfs whole disks as it is told ZFS love to manage itself entire disks. Unfortunately this way of managing disks leads to disks without labels/partitions scheme : the partition table remains clear , so it not clearly visible to...

Hi, 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...

Hello, I've tried using FreeBSD but due to a lot of unsupported software and a few strange interactions with my CPU I simply wish to install another operating system. On Linux this would be easy, just use 'dd if=myiso.iso of=/dev/sdb (my ssd partition)'. However, when I tried to do this on...

Hello All, I'm trying to restore my boot mirror (2 identical USB sticks) using gpart backup and gpart restore but getting an error. # gpart list da0 Geom name: da0 modified: false state: OK fwheads: 255 fwsectors: 63 last: 31260638 first: 34 entries: 128 scheme: GPT Providers: 1. Name: da0p1...

I have an issue with gpart, it will not let me delete partition ada0p2 responding with “Device Busy” The man page gpart(8) says this may be shown if a partition exists but I cannot seem to delete partition 2 in my case via gpart delete or gpart destroy This is a used disk but new to the...

I'm trying to create the same partition to make it raid, but it doesn't work. Can I make only start 40 with gpart in FreeBSD 12? # camcontrol devlist <Samsung SSD 850 PRO 512GB EXM02B6Q> at scbus6 target 0 lun 0 (pass5,ada4) # new ssd <Samsung SSD 850 PRO 512GB EXM02B6Q> at scbus11 target...

Hi I want to build a file server using zfs. I installed the os on mirrored zfs from the bsd installation. The installation formatted the drives automatically with FreeBSD-zfs partition. Now I want to add drives to my new pool called Data. This drives are new. Do I need to gpart the drives...

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. gpart list Geom name: ada0...

As we're running out of disk space, I've added another block storage device and made it a zfs partition with gpart : $ gpart show => 40 125829040 vtbd0 GPT (60G) 40 1024 1 freebsd-boot (512K) 1064 6291456 2 freebsd-zfs (3.0G) 6292520...

I do not understand why gpart thinks that 4k alignment means starting first partition at sector 41, instead of usual 40. Sector size is 512, so 4k alignment should result in starting 40. [root@cyan ~]# gpart create -s GPT ada0 ada0 created [root@cyan ~]# gpart add -t freebsd-boot -s 1024 ada0...

I have a ZFS pool consisting of two drives in a mirror VDEV. Now I'm replacing one with a larger capacity. So I first add the 3rd (new) drive to the VDEV for resilvering, before I detach the small drive. However when I partition the new drive in the same way I partitioned my existing drives, I...

I setup this HDD with zfs but no swap, now even with 32GB of ram I am running into issues related to swap. I created a swap file but I've been told that's a bad idea and can lead to deadlocks. My goal is to eventually debug the programs that I am using to see how to lower their memory usage but...

Hello, I have simple ZFS mirror from 2 disks. Contains zroot. Is bootable (GPT). 1) ZFS mirror was created during FreeBSD installation - I assume, that installer wrote proper gpt bootsector to both disks, so when one disk die in the future, system can boot from second disk - is this true? 2)...

OK I'm tracking CURRENT, where I have this issue. But I don't think it has anything to do with the fact that it's CURRENT. As writing the headers/tables on an 11 box, results in the same error after rebooting with the drive in the CURRENT box. Specifics; Only occurs on USB connected drives --...

Hi! Who can tell how to increase the disk space allocated under /usr/home? # freebsd-version 11.0-RELEASE-p8 # cat /etc/rc.conf | grep zfs zfs_enable="YES" # cat /etc/rc.conf | grep vmw vmware_guest_vmblock_enable="NO" vmware_guest_vmhgfs_enable="NO" vmware_guest_vmmemctl_enable="NO"...

Hello, I have a UEFI System with GPT Partition Table. During the installation of FreeBSD 11, I need to format a partition to UFS2. The FreeBSD installer does not allows to format an existing partition. It instead only allows to create a new partition, which will be then be formatted. Is...

(First post, so hopefully I get my formats right here...) I've been using a very old Open Solaris system with ZFS in a purely offline application for a few years. I moved to a new FreeBSD system (10.3-RELEASE-p4) a few weeks ago. Things are going very well, except for odd behavior with my...
