You can expand the storage pool by adding additional SDs to it. Before expanding a
storage pool review the following information:
- Expand the storage pool by increasing the storage capacity by adding additional SDs to the storage system. The storage pool can grow up to a maximum capacity of 1 PiB (Pebibyte) or 256 SDs. When you expand the storage pool by adding SDs, this process does not interrupt client access to the storage resources.
- When you initially create a storage pool, it contains a single stripeset. Each time you expand the storage pool, you add another stripeset. You can add up to a maximum of 64 stripesets.
- The storage pool contains file systems and allows users to manage settings that apply to all file systems within it. One of these settings is File System Auto-expansion, this setting determines whether all file systems in the pool can automatically expand. You can enable or disable this setting to control the expansion of all file systems in the pool. By default, a storage pool supports up to 32 file systems. File systems that have been recently deleted but remain in the recycle bin do not count toward this limit.
- If one tier of a tiered storage pool fills up before the other tier, you can expand only the filled tier without expanding the other. When expanding a tier, make sure the SDs you add have the same performance characteristics as those already in the tier. For example, don’t add NL SAS (nearline SAS) SDs to a tier that already consists of flash drives.
