Important zones fixes in Solaris 11.3 SRU 2.4

Mike Gerdts
Principal Software Engineer

Solaris 11.3 SRU 2.4 has some fixes that are likely of interest to you if you are reading this blog.  These fixes include:

  • Free memory is no longer copied during live migration and suspend/resume.  If you have a lot of free memory - especially free memory that wasn't free at some point - this can significantly reduce migration time.
  • During zoneadm migrate, progress reports keep you up to date on how the migration is progressing.
  • vmstat and iostat are now much faster to start in zones.
  • Operations involving access to device nodes in /dev/zvol are much faster.  That is, ls, find, and open() may be faster.  There are no zone-specific changes that would impact the performance of reads and writes to ZFS volumes.
Of course there are a bunch of other fixes in zones and elsewhere that may be important to you too.  Check out My Oracle Support Doc ID 2077717.1 for details.
