hi ...
i have added a physical disk to the pool with
""zpool add <poolname> diskname"""... after that i realized that i have to mirror it instead..then i tried to take that disk out of the pool but i m not able to do that..
i have gone through many unix help sites , nothing worked ,
so please... (6 Replies)
Hi,
I have an X86pc with Solaris 10 and ZFS system. It has 8 similar disks.
I need help in creating some zpools and changing the mount-point of a slice.
Currently, the zpool in my system is like this:
root@abcxxx>zpool status
pool: rpool
state: ONLINE
scrub: none requested... (4 Replies)
Hello,
Does anyone know how I can tell what disk are being not being used by a zpool?
For example in Veritas Volume manager, I can run a "vxdisk list" and disks that are marked as "online invalid" are disk that are not used.
I'm looking for a similar command in ZFS which will easily show... (5 Replies)
Hi All,
I am getting zpool corrupted message under zpool status command.What could be the reason for this.I had observed this zpool was full this morning after this i am seeing this error.

pool: R5
state: DEGRADED

Hello experts,
I have a solaris 10 (SunOS 5.10 Generic_148888-05 sun4u sparc SUNW,SPARC-Enterprise) that by mistake I added a second san space of 700g to the pool. the whole pool is now 1.2T and, I need to take the space away from the pool and, make the pool 700g total. this is live oracle... (7 Replies)
I have a single zpool with 3 2-way mirrors ( 3 x 2 way vdevs) it has a degraded disk in mirror-2, I know I can suffer a single drive failure, but looking at this how many drive failures can this suffer before it is no good? On the face of it, I thought that I could lose a further 2 drives in each... (4 Replies)
Now this doesnt look right to me. All of these disks are 100Gb LUNS so total zpool size is 300Gb.
Am I right in saying that this zpool consists of two disks plus one more disk that is 6 way mirrored?
So a bit pointless because only one of the three is mirrored (and 6 way is a bit of overkill... (3 Replies)

gptzfsboot
GPTZFSBOOT(8) BSD System Manager's Manual GPTZFSBOOT(8)NAME
gptzfsboot -- GPT bootcode for ZFS on BIOS-based computers
DESCRIPTION
gptzfsboot is used on BIOS-based computers to boot from a filesystem in a ZFS pool. gptzfsboot is installed in a freebsd-boot partition of a
GPT-partitioned disk with gpart(8).
IMPLEMENTATION NOTES
The GPT standard allows a variable number of partitions, but gptzfsboot only boots from tables with 128 partitions or less.
BOOTING
gptzfsboot tries to find all ZFS pools that are composed of BIOS-visible hard disks or partitions on them. gptzfsboot looks for ZFS device
labels on all visible disks and in discovered supported partitions for all supported partition scheme types. The search starts with the disk
from which gptzfsboot itself was loaded. Other disks are probed in BIOS defined order. After a disk is probed and gptzfsboot determines
that the whole disk is not a ZFS pool member, the individual partitions are probed in their partition table order. Currently GPT and MBR
partition schemes are supported. With the GPT scheme, only partitions of type freebsd-zfs are probed. The first pool seen during probing is
used as a default boot pool.
The filesystem specified by the bootfs property of the pool is used as a default boot filesystem. If the bootfs property is not set, then
the root filesystem of the pool is used as the default. zfsloader(8) is loaded from the boot filesystem. If /boot.config or /boot/config is
present in the boot filesystem, boot options are read from it in the same way as boot(8).
The ZFS GUIDs of the first successfully probed device and the first detected pool are made available to zfsloader(8) in the
vfs.zfs.boot.primary_vdev and vfs.zfs.boot.primary_pool variables.
USAGE
Normally gptzfsboot will boot in fully automatic mode. However, like boot(8), it is possible to interrupt the automatic boot process and
interact with gptzfsboot through a prompt. gptzfsboot accepts all the options that boot(8) supports.
The filesystem specification and the path to zfsloader(8) are different from boot(8). The format is
[zfs:pool/filesystem:][/path/to/loader]
Both the filesystem and the path can be specified. If only a path is specified, then the default filesystem is used. If only a pool and
filesystem are specified, then /boot/zfsloader is used as a path.
Additionally, the status command can be used to query information about discovered pools. The output format is similar to that of zpool
status (see zpool(8)).
The configured or automatically determined ZFS boot filesystem is stored in the zfsloader(8) loaddev variable, and also set as the initial
value of the currdev variable.
FILES
/boot/gptzfsboot boot code binary
/boot.config parameters for the boot block (optional)
/boot/config alternative parameters for the boot block (optional)
EXAMPLES
gptzfsboot is typically installed in combination with a ``protective MBR'' (see gpart(8)). To install gptzfsboot on the ada0 drive:
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0
gptzfsboot can also be installed without the PMBR:
gpart bootcode -p /boot/gptzfsboot -i 1 ada0

gptzfsboot appeared in FreeBSD 7.3.

BUGS
gptzfsboot looks for ZFS meta-data only in MBR partitions (known on FreeBSD as slices). It does not look into BSD disklabel(8) partitions
that are traditionally called partitions. If a disklabel partition happens to be placed so that ZFS meta-data can be found at the fixed off-
sets relative to a slice, then gptzfsboot will recognize the partition as a part of a ZFS pool, but this is not guaranteed to happen.
