zfs: out of temporary buffer space
posted in: computer | 0
system: FreeBSD v13.0-p7

reason: the bootloader is broken (e.g. after update)

solution: reinstall the bootloader(s) to your boot disk(s)

1. Boot from recent FreeBSD image
2. find out the devicenames and boot partition number from your boot-disks
   gpart show
   (the partition named “freebsd-boot” is the boot partition on every disk)
3. reinstall the pMBR and GPT ZFS bootloader (for every booting disk)
   gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i <boot-partition-number> <devicename>
   (e.g. gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0)
   (e.g. gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada1)
4. reboot
