if the data on one of the disks is missing and there are no other replicas of this device... your data is gone. zfs is no "wonder" filesystem...
i don't know if you can get the config of an exported zpool. haven't tried this yet...

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)

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)

GFREP(1) GFREP(1)
NAME
gfrep - replicate Gfarm files
SYNOPSIS
gfrep [ -mnqvx ] [ -S source-domainname ] [ -D destination-domainname ] [ -h source-hostfile ] [ -H destination-hostfile ] [ -N num-of-
replicas ] [ -j num-of-threads ] path ...
DESCRIPTION
gfrep creates specified number of replicas of Gfarm files specified by the path to specified set of destination hosts. When set of source
hosts are specified, only files stored on the set of source hosts are replicated. A set of hosts can be specified by a domain name and/or
a host file. When both a domain name and a host file are specified, a set of hosts is determined by both conditions.
If the path parameter is a directory, files under the directory will be copied recursively.
OPTIONS
-S source-domainname
Specifies the domain name of source filesystem nodes from which replicas will be copied.
-D destination-domainname
Specifies the domain name of destination filesystem nodes to which replicas will be copied.
If neither this nor the -H option is specified, replicas may be copied to any available host.
-h source-hostfile
Specifies a file which describes hostnames of source filesystem nodes from which the replica will be made. The source-hostfile con-
sists of a filesystem node name on each line.
if ``-'' is specified, standard input is used to read the host list.
-H destination-hostfile
Specifies a file which describes hostnames of destination filesystem nodes on which the replica will be made. The destination-host-
file consists of a filesystem node name on each line.
if ``-'' is specified, standard input is used to read the host list.
-N num-of-replicas
Specifies the required number of file replicas, counting already existing ones. If there are a sufficient number of replicas in the
destination hosts, neither any copying nor any removal will be done.
If this option is not specified, -N 1 is assumed.
-j num-of-threads
Specifies the number of threads to create file replicas simultaneously. This option is only available when compiled by an OpenMP C
compiler. By default, it will be the smallest among the number of total files, the number of source hosts, and the number of desti-
nation hosts.
-m Lets gfrep command do a migrate/move, instead of doing replication.
-x Removes file replicas when a set of destination nodes has more file replicas than specified.
-n Displays files to be replicated, but does nothing.
-q Suppresses non-error messages.
-v Displays verbose output.
-? Displays a list of command options.
BUGS
A source host is not always selected within a set of source hosts.
