I found my problem: I only had one disk, and I guess it was entirely allocated to my existing ufs filesystem. Once I added a new disk, I was able to specify it as the device and I was able to successfully create a zpool/zfs filesystem:
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)

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.

ZFS-FUSE(8) [FIXME: manual] ZFS-FUSE(8)NAME
zfs-fuse - ZFS filesystem daemon
SYNOPSIS
zfs-fuse [--pidfile filename] [--no-daemon] [--no-kstat-mount] [--disable-block-cache] [--disable-page-cache] [--fuse-attr-timeout SECONDS]
[--fuse-entry-timeout SECONDS] [--log-uberblocks] [--max-arc-size MB] [--fuse-mount-options OPT,OPT,OPT...]
[--min-uberblock-txg MIN] [--stack-size=size] [--enable-xattr] [--help]
DESCRIPTION
This manual page documents briefly the zfs-fuse command.
zfs-fuse is a daemon which provides support for the ZFS filesystem, via fuse. Ordinarily this daemon will be invoked from system boot
scripts.
OPTIONS
This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included
below. For a complete description, see the Info files.
-h --help
Show summary of options.
-p filename --pidfile filename
Write the daemon's PID to filename after daemonizing. Ignored if --no-daemon is passed. filename should be a fully-qualified path.
-n --no-daemon
Stay in foreground, don't daemonize.
--no-kstat-mount
Do not mount kstats in /zfs-kstat
--disable-block-cache
Enable direct I/O for disk operations. Completely disables caching reads and writes in the kernel block cache. Breaks mmap() in ZFS
datasets too.
--disable-page-cache
Disable the page cache for files residing within ZFS filesystems. Not recommended as it slows down I/O operations considerably.
-a SECONDS --fuse-attr-timeout SECONDS
Sets timeout for caching FUSE attributes in kernel. Defaults to 0.0. Higher values give a 40% performance boost.
-e SECONDS --fuse-entry-timeout SECONDS
Sets timeout for caching FUSE entries in kernel. Defaults to 0.0. Higher values give a 10000% performance boost but cause file
permission checking security issues.
--log-uberblocks
Logs uberblocks of any mounted filesystem to syslog
-m MB --max-arc-size MB
Forces the maximum ARC size (in megabytes). Range: 16 to 16384.
-o OPT... --fuse-mount-options OPT,OPT,OPT...
Sets FUSE mount options for all filesystems. Format: comma-separated string of characters.
-u MIN --min-uberblock-txg MIN
Skips uberblocks with a TXG < MIN when mounting any fs
-v MB --vdev-cache-size MB
adjust the size of the vdev cache. Default : 10
--zfs-prefetch-disable
Disable the high level prefetch cache in zfs. This thing can eat up to 150 Mb of ram, maybe more
--stack-size=size
Limit the stack size of threads (in kb). default : no limit (8 Mb for linux)
-x --enable-xattr
Enable support for extended attributes. Not generally recommended because it currently has a significant performance penalty for many
small IOPS
-h --help
Show this usage summary.
REMARKS ON PRECEDENCE
Note that the parameters passed on the command line take precedence over those supplied through /etc/zfs/zfsrc.
BUGS /CAVEATS
The path to the configuration file (/etc/zfs/zfsrc) cannot at this time be configured.
Most existing packages suggest settings can be set at the top of their init script. These get frequently overridden by a (distribution
specific) /etc/default/zfs-fuse file, if it exists. Be sure to look at these places if you want your changes to options to take effect.
The /etc/zfs/zfsrc is going to be the recommended approach in the future. So, packagers, please refrain from passing commandline parameters
within the initscript (except for --pid-file).
