Operating Systems Solaris Need help to understand zfs rpool space allocation Post 302969378 by jlliagre on Tuesday 22nd of March 2016 06:39:31 AM

Just have a look to the column labeled "REFER" in "zfs list" output. It shows for each dataset the actual size occupied by that dataset.

Out of a 100 GB pool, 32 GB is taken by the swap area, 15 GB by the dump area, 11.5 by the root file system, 4.61 Gb by a user's file system, 2 GB by /var, 1.39 GB by /var/share. All remaining datasets are much smaller. The sum of all REFER values is 70 GB which match the 29 GB available you got with "df".

I would recommend being careful with reducing the swap size unless you really know how much swap your system might need in the future. Relocating the swap elsewhere, as already suggested by Peasant, would on the other hand be a good idea and the simplest way to recover 32 GB of disk space in your root pool. You might also relocate your 15 GB dump area elsewhere but there are more constraints about the receiving pool.

NAME
paps - UTF-8 to PostScript converter using Pango SYNOPSIS
paps [options] files... DESCRIPTION
paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves through the pango ft2 backend. OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. --landscape Landscape output. Default is portrait. --columns=cl Number of columns output. Default is 1. --font=desc Set the font description. Default is Monospace 12. --rtl Do rtl layout. --paper ps Choose paper size. Known paper sizes are legal, letter, a4. Default is A4. --bottom-margin=bm Set bottom margin in postscript points (1/72 inch). Default is 36. --top-margin=tm Set top margin. Default is 36. --left-margin=lm Set left margin. Default is 36. --right-margin=rm Set right margin. Default is 36. --help Show summary of options. --header Draw page header for each page. --markup Interpret the text as pango markup. --encoding=ENCODING Assume the documentation encoding is ENCODING. --lpi Set the lines per inch. This determines the line spacing. --cpi Set the characters per inch. This is an alternative method of specifying the font size. --stretch-chars Indicates that characters should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops behaviour. AUTHOR
