It's about Solaris10. I didn't use RBAC in s11 but as I can see there is no built-in Primary Administrator profile. I think that you can create profile approprite for your needs for example just with zfs command.
There is profile related to filesystem management.
Code:
root@solaris11:/etc/security/exec_attr.d# grep zfs *
core-os:ZFS File System Management:solaris:cmd:RO::/usr/sbin/zfs:euid=0
You can try if they can meet your needs.
I have tested and it looks ok for creating zfs filesystem.
Code:
user1@solaris11:~$ profiles
Basic Solaris User
All
user1@solaris11:~$ pfexec zfs create pula01/test
cannot create 'pula01/test': permission denied
Code:
root@solaris11 # usermod -P +'ZFS File System Management' user1
Code:
user1@solaris11:~$ profiles
ZFS File System Management
Basic Solaris User
All
user1@solaris11:~$ zfs create pula01/test
cannot create 'pula01/test': permission denied
user1@solaris11:~$ pfexec zfs create pula01/test
Another edit
ZFS File System Management works fine for zfs command but for zpool command you should use different profile:
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)

I have a branded zone txdjintra that utilizes a pool named Pool_djintra that is no longer required. There is a 150 Gig Lun assigned to the pool that I need to reassign to another branded zone txpsrsrv07 with a pool named Pool_txpsrsrv07 on the same sun blade. What is the process to do this?

bup-margin
bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
