Description

ztest sometimes fails due to running out of space in the pool if run with unrealistic pool configurations, e.g. 3-wide RAIDZ2 with 4KB sector size. In these configurations, the "slop space" used for pool-wide metadata (e.g. space maps) is insufficient with the default vdev size (64MB). Therefore ztest should default to a slightly larger vdev size (128MB).
