Beware that relocating the whole /usr to a zfs filesystem might possibly make your system unbootable.
Relocating parts of /usr using symbolic links (outside /usr/local which isn't part of Solaris) would likely render your system un-patchable, un-upgradeable and of certainly unsupported.

Hi,
Is their an easy way to realloate hard drive space on Solaris 10.
For example :
/c20td0 10G
/space 90 G
I would like to move some of the hard-drive space from "/space" and add it to "/c20td0". In Windows this can be easily done using Partition magic, anything similar for UNIX? (4 Replies)

Hi Folks!
Its been a while since I worked with ZFS but basically, I need to monitor free space for Solaris 10 & 11 systems (with & without zones)
I am hoping that any space commands only need to be run from the global zone (to simplify matters)
However, I'm not not sure if there are exceptions... (2 Replies)

cvaffinity
cvaffinity(1) cvaffinity(1)
NAME
cvaffinity - Set an affinity type
SYNOPSIS
cvaffinity -s <key> filename
cvaffinity -l filename
cvaffinity -d filename
DESCRIPTION
cvaffinity can be used to set an affinity for a specific storage pool
on a file or directory, or list the current affinity. An affinity is
created in a storage pool through the volume configuration (see
cvfs_config(4).) It is a name, up to eight (8) characters, describing a
special media type. Use cvadmin (1) to see what affinity sets are
assigned to the configured storage pools.
If the affinity does not exist for any of the storage pools, then the
allocation will occur on the non-exclusive storage pool. If there is
no non-exclusive storage pool, an ENOSPC is returned.
USAGE
-s <key> is the Affinity Key to associate with the file or direc-
tory and is defined as a 'MediaType' name in the file system
configuration. Use the program 'cvadmin' to see the Affinity
Keys active in this file system. For files with an Affinity,
new blocks allocated to that file are placed on a storage pool
with the specified Affinity. For directories with an Affinity
new files created in that directory inherit the Affinity from
the directory.
-l This option says to just list the affinity for the specified
file and exit.
-d This option says to delete the affinity from the specified file
or directory, if one exists.
<filename>
Specifies any file or directory on the targeted volume. When
the -k option (set session affinity) is specified, or no other
option is specified, the filename option is used as a read-only
reference handle in order to access the volume. When the -s,
-d, or -l options are used, the filename option specifies the
file or directory operated on.
EXAMPLES
List the affinity on the file /usr/clips/foo.
rock # cvaffinity -l /usr/clips/foo
Set this file or directory to use the storage pool that has the jmfn8
affinity type.
rock # cvaffinity -s jmfn8 /usr/clips/filename
Remove the affinity from the /usr/clips/mydir, if one is currently
assigned.
rock # cvaffinity -d /usr/clips/mydir
