Data balance across vdevs
...ne of the scenarios I''m testing is the addition of vdevs to a pool.
Starting out, I populated a pool that had 4 vdevs. Then, I added 3 more
vdevs and would like to balance this data across the pool for
performance. The data may be in subdirectories like this:
/proxy_data/instrument_X/domain_Y. Because of the access pattern across
the cluster, I need these subdirectories each spread across as many
disks as possible. Simply putting the data evenly on all vdevs is
suboptimal because it is likely the case that different files within a
single domain from a single instrument may be used...
