Exporting zpool sitting on different disk partition
Hello,
I need some help in recovering ZFS pool. Here is scenerio. There are two disks -
c0t0d0 - This is good disk. I cloned it from other server and boot server from this disk.
c0t1d0 - This is original disk of this server, having errors. I am able to mount it on /mnt. So that I can copy required data from this to c0t0d0
Below pool is not imported yet and copy of another server, from where I have cloned.
Code:
# zpool import
pool: zplctpool
id: 11623878967666942759
state: DEGRADED
status: The pool was last accessed by another system.
action: The pool can be imported despite missing or damaged devices. The
fault tolerance of the pool may be compromised if imported.
see: http://www.sun.com/msg/ZFS-8000-EY
config:
zplctpool DEGRADED
mirror DEGRADED
c0t0d0s7 FAULTED corrupted data
c0t0d0s7 ONLINE
I do not want this zplctpool, it can be deleted. Instead, I want zplctpool, which is sitting on c0t1d0s7
Hi All,
While my LINUX SERVER installed we didnt' used all the space for partitions. with what tool I can create a new partition or mount point to use the free space.
I tried the command fdisk and diskdruid. They are not working.
Thanks in advance
With Best regards,
Varma. (2 Replies)
Have a solaris x86 running solaris 9.
Root disk - logical - mirrored.
I added 2 more disks today - and I have mirrored them using array configuration utility.
I did a reconfiguration boot - and now I can see the logical disk using format:
I then partitioned this the way I wanted (I hope)... (4 Replies)
I have 3 disks to partition in following file system.
c1t1d0 = 72gb
/prod1
/prod2
/prod3
/prod4
/prod5
I am first time using "format" command to do this. How can i name with specified size.

Hello,
I am a new member of the forum.
I need an idea on how to partition the disk.
My situation is as follows:
I have two 3TB disks ognuno.In 6TB total then, but I have to do to force a RAID 1 so my space will be 3TB. I'll have to force install RedHat 5.8 and liquids is to be taken in... (4 Replies)
Hi,
Quick question.
I have a data zpool that consists of 1 disk.

I added a disk to a zpool using "zpool add diskname"
My intention was mirror a zpool disk that no mirror; that is a zpool with only one disk. I did not issue the right command. Now, the disk has been added successfully but I cannot remove nor detach it as Solaris 11 thinks it has data on it... (14 Replies)
issue,
I had a zpool which was full
pool_temp1 199G 197G 1.56G 99% ONLINE -
pool_temp2 199G 196G 3.09G 98% ONLINE -
as you can see, full
so I replaced with a larger disk.
zpool replace pool_temp1 c3t600144F0FF8BA036000058CC1DB80008d0s0... (2 Replies)
Generally, this is what we do:-
On primary, export 2 LUNs (add-vdsdev).
On primary, assign these disks to the ldom in question (add-vdisk).
On ldom, created mirrored zpool from these two disks.
On one server (which is older) we have:-
On primary, create mirrored zpool from the two LUNs.... (4 Replies)
On an OmniOS server, I removed a single-disk pool I was using for testing.
Now, when I run zpool import it will show it as FAULTED, since that single disk not available anymore.

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.
SEE ALSO dd(1), boot.config(5), boot(8), gptzfsboot(8), loader(8), zfsloader(8), zpool(8)HISTORY
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.
