On SX:CE, it would be looking at the file system list with zonecfg for inherit-pkg-dir. > Doing a zonecfg, i see > no differences between the zones, they don't contain "inherit-pkg-dir" ? In that case, it's harder to explain what you saw. Is it possible that 'catalogue4' was actually created as a clone of some other zone on that system you're comparing against? > somebody said that it is not possible to have sparse zones in os2008.11, > even if "man zonecfg" doesn't say nothing about it? I doubt it's possible to do that in the OpenSolaris distribution, as that's not based on System V packaging. The tools are different there. -- James Carlson, Solaris Networking Sun Microsystems / 35 Network Drive71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677 ___ zones-discuss mailing list zones-discuss@opensolaris.org

"REFER" is documented on the zfs(1M) man page. It's the amount of space accessible by the dataset and some or all of it may be shared with another dataset. If you're interested in the amount of disk space used, then the "USED" column is what you want. At a guess, the difference between these two machines is that 'catalogue4' was likely created as a sparse-root zone, while 'catalogue2' was created as a whole-root zone. The clones of that whole-root zone ('catalogue3' and 'test-drupal') use little disk space, as most of it is 'referred' from 'catalogue2'.
