Unable to create zfs zpool in FreeBSD 8.2: no such pool or dataset
I am trying to test simple zfs functionality on a FreeBSD 8.2 VM. When I try to run a 'zpool create' I receive the following error:
I was not sure what to put for the device, so I tried both da0s1a and da0, due to this output:
Just wondering if I am missing a step or doing something wrong.
edit: I'm starting to wonder if it's because I only have 1 'disk' in this VM, and perhaps the entire disk has been formatted to ufs and so I can't create a zpool on that disk? Do I need to add another disk in VMware?
Also, does anyone know what filesystems are natively supported in FBSD 6.x and 8.x? I believe 6.x supports ufs and 8.x supports ufs and zfs, but I am not positive.
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 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)
Hi All,
I want to write a script to create flar images on multiple servers. In non zfs filesystem I am using -X option to refer a file to exclude mounts on different servers.
but on ZFS -X option is not working. I want multiple mounts to be ignore on ZFS base system during flarecreate.

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)

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 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.

gnop
GNOP(8) BSD System Manager's Manual GNOP(8)NAME
gnop -- control utility for NOP GEOM class
SYNOPSIS
gnop create [-v] [-e error] [-o offset] [-r rfailprob] [-s size] [-S secsize] [-w wfailprob] dev ...
gnop configure [-v] [-e error] [-r rfailprob] [-w wfailprob] prov ...
gnop destroy [-fv] prov ...
gnop reset [-v] prov ...
gnop list
gnop status
gnop load
gnop unload
DESCRIPTION
The gnop utility is used for setting up transparent providers on existing ones. Its main purpose is testing other GEOM classes, as it allows
forced provider removal and I/O error simulation with a given probability. It also gathers the following statistics: number of read
requests, number of write requests, number of bytes read and number of bytes written. In addition, it can be used as a good starting point
for implementing new GEOM classes.
The first argument to gnop indicates an action to be performed:
create Set up a transparent provider on the given devices. If the operation succeeds, the new provider should appear with name
/dev/<dev>.nop. The kernel module geom_nop.ko will be loaded if it is not loaded already.
configure Configure existing transparent provider. At the moment it is only used for changing failure probability.
destroy Turn off the given transparent providers.
reset Reset statistics for the given transparent providers.
list See geom(8).
status See geom(8).
load See geom(8).
unload See geom(8).
Additional options:
-e error Specifies the error number to return on failure.
-f Force the removal of the specified provider.
-o offset Where to begin on the original provider.
-r rfailprob Specifies read failure probability in percent.
-s size Size of the transparent provider.
-S secsize Sector size of the transparent provider.
-w wfailprob Specifies write failure probability in percent.
-v Be more verbose.
SYSCTL VARIABLES
The following sysctl(8) variables can be used to control the behavior of the NOP GEOM class. The default value is shown next to each vari-
able.
kern.geom.nop.debug: 0
Debug level of the NOP GEOM class. This can be set to a number between 0 and 2 inclusive. If set to 0, minimal debug information is
printed. If set to 1, basic debug information is logged along with the I/O requests that were returned as errors. If set to 2, the
maximum amount of debug information is printed including all I/O requests.
EXIT STATUS
Exit status is 0 on success, and 1 if the command fails.
EXAMPLES
The following example shows how to create a transparent provider for disk /dev/da0 with 50% write failure probability, and how to destroy it.
gnop create -v -w 50 da0
gnop destroy -v da0.nop
The traffic statistics for the given transparent providers can be obtained with the list command. The example below shows the number of
bytes written with newfs(8):
gnop create da0
newfs /dev/da0.nop
gnop list

The gnop utility appeared in FreeBSD 5.3.
