Subject: [PATCH] Increase buffer size for nvlist for large configurations It's
still not clear to me why the default value here is large enough Solaris. I
hit this limit again when setting up 120 SATA drives configured as 15 raidz2
groups each containing 8 drives. We expect to go bigger so we may just want
to spend a little time and figure out how to make this all dynamic.
