GPUs starting with the HD7000 series / Tahiti) or i915kms (for Intel

APUs starting with HD3000 / Sandy Bridge) through kld_list in

/etc/rc.conf. radeonkms for older AMD GPUs can be loaded and there are

some positive reports if EFI boot is NOT enabled (similar to amdgpu).

For amdgpu: kld_list="amdgpu"

Tööpõhimõte

Root-on-ZFS viilisel paigaldatud FreeBSD arvuti plokkseadmele moodustatakse GPT partitsioonitabel

ZFS failisüsteemi kasutamine Linux töökohaarvutist

Nt eriolukorras kui FreeBSD iseseisvalt ei käivitu saab zfs andmetele ligi selliselt

  • kopeerida internetist tavaline nt Ubuntu v. 21.10 live-server-image .iso fail
  • käivitada ubuntu abil freebsd arvuti nn live režiimis
  • importida zfs failisüsteemid, monteerides altroot kataloogi suhtes
# zpool import -o altroot=/mnt -f zroot

Tulemusena on failisüsteemnid moniteeritud ja kasutatavad 

root@ubuntu-server:~# findmnt -t zfs
TARGET                SOURCE                  FSTYPE OPTIONS
/mnt/tmp              zroot/tmp               zfs    rw,nosuid,noatime,xattr,noacl
/mnt/zroot            zroot                   zfs    rw,noatime,xattr,noacl
/mnt/var/crash        zroot/var/crash         zfs    rw,nosuid,noexec,noatime,xattr,noacl
/mnt/usr/home         zroot/usr/home          zfs    rw,noatime,xattr,noacl
/mnt/usr/ports        zroot/usr/ports         zfs    rw,nosuid,noatime,xattr,noacl
/mnt/var/audit        zroot/var/audit         zfs    rw,nosuid,noexec,noatime,xattr,noacl
/mnt/var/tmp          zroot/var/tmp           zfs    rw,nosuid,noatime,xattr,noacl
/mnt/usr/src          zroot/usr/src           zfs    rw,noatime,xattr,noacl
/mnt/var/log          zroot/var/log           zfs    rw,nosuid,noexec,noatime,xattr,noacl
/mnt/var/mail         zroot/var/mail          zfs    rw,xattr,noacl
...

Kasutamise lõpetamiseks sobib öelda 

# zpool export zroot

Paistab, et nii kasutamine ei sega seejärel FreeBSD kasutamist tavalisel viisil.

GPT partitsioonitabeli parandamine

Enne 

# dmesg | grep GEOM
GEOM: ada0: the secondary GPT header is not in the last LBA.

# gpart show ada0
=>       3  10552571  ada0  GPT  (5.0G) [CORRUPT]

   2163866   8388708     4  freebsd-ufs  (4.0G)

Parandamine 

# gpart recover ada0

Pärast 

# gpart show ada0
=>       3  10552571  ada0  GPT  (5.0G)
         3       127     1  freebsd-boot  (64K)

saadakse teada millise paketi koosseisu kõnealune fail kuulub ja reinstallitakse vastav pakett 

root@freebsd-tk:~ # pkg which /usr/local/llvm12/lib/libLLVMMCParser.a
/usr/local/llvm12/lib/libLLVMMCParser.a was installed by package llvm12-12.0.1_9

Nüüd on aga see probleem paistab välja nii

Tundub, et selle vastu aitab 

# zpool scrub zroot

Tulemus peaks olema ilus
