Trying to create ZFS slice on rpool

I have a 240GB disk as rpool. I have installed Solaris 11.3 to a partition which is 110GB. Now I have another 130GB which is unallocated. I want to use that additional space as a temporary folder to be shared between Solaris and Linux. The additional space had no /dev/dsk/c2t4... entry so I used...

Help with mirroring rpool

Hello, I need some help mirroring my rpool. I have a 60gb ssd running the rpool alone and want to mirror it for redundancy so I bought a 120gb ssd that I found for a good price. 60gb drives aren't as easy to find at a good price anymore it seems. I (a bit naively) thought after reading...

ZFS rpool physical disk move

I'd like to finish setting up this system and then move the secondary or primary disk to another system that is the exact same hardware. I've done things like this in the past with ufs and disk suite mirroring just fine. But I have yet to do it with a zfs root pool mirror. Are there any...

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.
	      915 of 1612581 (0.057%)
