Hi,
if one have a current pool that includes 1 vdev in RaidZ1 (3 disks) and want to add a new RaidZ1 vdev (3 disks), what is the pros and cons of:
1. creating a new pool vs. extending the existing pool.
2. in case of disk faults, which will be easier to handle? (if for example it needs at worst case data recovery).
3. upgrading vdev in the future to larger disks.
All I know that it is easier to know which dataset belongs to which vdev when there are 2 pools, but I'm not sure how a pool with multiple vdevs spreads its data/datasets.
