  • Can you add the output of metastat -p and add the output of what disks make up md500 to your question – Fegnoid Oct 28 '14 at 11:30
  • Also is there anything in /var/adm/messages that stands out? – Fegnoid Oct 28 '14 at 11:31
  • there is no error /var/adm/messages $ metastat -p bash: metastat: command not found – Asif Patel Oct 28 '14 at 12:09
  • it should be in /usr/sbin, also is this a non global zone? – Fegnoid Oct 28 '14 at 12:36
  • Long shot, but check the directory size of /tmp -- for some reason, too many files in /tmp slows down everything, including file writes (even those outside /tmp) – barrycarter Oct 28 '14 at 17:30
