I have installed FreeBSD onto a raw image file using QEMU Emulator successfully. I have formatted the image file using the ZFS file system (ZFS POOL).
Using the following commands below I have successfully mounted the image file ready to be opened by zpool
However with the next command show below....
I get the following error message
I cannot find anywhere online about the feature called 'spacemap_v2'. How do I install this or how do I mount my zfs pool to be writable. I know I can mount it as read-only but that defeats the purpose of what I want to do as I want to be able to write data to copy/paste data in its mountable platform interface.
Does anyone know how to achieve this. I shall be grateful for a response.
Regards
This morning I started receiving an alert saying "Legato Storage Manager media (waiting) backup to pool 'Default' waiting for 1 writable tape" but when I go check the status of the Legato autostart, its disabled.
So why is it asking a tape ? (1 Reply)
Hi all
I plan to install Solaris 10U6 on some SPARC server using ZFS as root pool, whereas I would like to keep the current setup done by VxVM:
- 2 internal disks: c0t0d0 and c0t1d0
- bootable root-volume (mirrored, both disks)
- 1 non-mirrored swap slice
- 1 non-mirrored slices for Live... (1 Reply)

I created a pool the other day. I created a 10 gig files just for a test, then deleted it.
I proceeded to create a few files systems. But for some reason the pool shows 10% full, but the files systems are both at 1%? Both files systems share the same pool.
When I ls -al the pool I just... (6 Replies)
Hi guys,
We had created a pool as follows:
zpool create filing_pool raidz c1t2d0 c1t3d0 ........
Due to some requirement, we need to destroy the pool and re-create another one. We wish to know now which disks have been included in the filing_pool, how do we list the disks used to create... (2 Replies)
I need to migrate an existing raidz pool to a new raidz pool with larger disks. I need the mount points and attributes to migrate as well. What is the best procedure to accomplish this. The current pool is 6x36GB disks 202GB capacity and I am migrating to 5x 72GB disks 340GB capacity. (2 Replies)
Other than export/import, is there a cleaner way to rename a pool without unmounting de FS?
Something like, say "zpool rename a b"?
Thanks. (2 Replies)
installed Solaris 11 Express on my server machine a while ago. I created a Z2 RAID over five HDDs and created a few ZFS filesystems on it.
Once I (unintentionally) managed to fill the pool completely with data and (to my surprise) the filesystems stopped working - I could not read/delete any... (3 Replies)

zfsboot
ZFSBOOT(8) BSD System Manager's Manual ZFSBOOT(8)NAME
zfsboot -- bootcode for ZFS on BIOS-based computers
DESCRIPTION
zfsboot is used on BIOS-based computers to boot from a filesystem in a ZFS pool. zfsboot is installed in two parts on a disk or a partition
used by a ZFS pool. The first part, a single-sector starter boot block, is installed at the beginning of the disk or partition. The second
part, a main boot block, is installed at a special offset within the disk or partition. Both areas are reserved by the ZFS on-disk specifi-
cation for boot use. If zfsboot is installed in a partition, then that partition should be made bootable using appropriate configuration and
boot blocks described in boot(8).
BOOTING
The zfsboot boot process is very similar to that of gptzfsboot(8). One significant difference is that zfsboot does not currently support the
GPT partitioning scheme. Thus only whole disks and MBR partitions, traditionally referred to as slices, are probed for ZFS disk labels. See
the BUGS section in gptzfsboot(8) for some limitations of the MBR scheme support.
USAGE
zfsboot supports all the same prompt and configuration file arguments as gptzfsboot(8).
FILES
/boot/zfsboot boot code binary
/boot.config parameters for the boot block (optional)
/boot/config alternative parameters for the boot block (optional)
EXAMPLES
zfsboot is typically installed using dd(1). To install zfsboot on the ada0 drive:
dd if=/boot/zfsboot of=/dev/ada0 count=1
dd if=/boot/zfsboot of=/dev/ada0 iseek=1 oseek=1024
If the drive is currently in use, the GEOM safety will prevent writes and must be disabled before running the above commands:
sysctl kern.geom.debugflags=0x10
zfsboot can also be installed in an MBR slice:
gpart create -s mbr ada0
gpart add -t freebsd ada0
gpart create -s BSD ada0s1
gpart bootcode -b /boot/boot0 ada0
gpart set -a active -i 1 ada0
dd if=/boot/zfsboot of=/dev/ada0s1 count=1
dd if=/boot/zfsboot of=/dev/ada0s1 iseek=1 oseek=1024
Note that commands to create and populate a pool are not shown in the example above.

zfsboot appeared in FreeBSD 7.3.

BUGS
Installing zfsboot with dd(1) is a hack. ZFS needs a command to properly install zfsboot onto a ZFS-controlled disk or partition.
