Compression Level<\/strong> : \u30c7\u30fc\u30bf\u306e\u5727\u7e2e\u30ec\u30d9\u30eb<\/p>\n
Encode information in less space than the original data occupies. It is recommended to choose a compression algorithm that balances disk performance with the amount of saved space.
\nLZ4 is generally recommended as it maximizes performance and dynamically identifies the best files to compress.
\nGZIP options range from 1 for least compression, best performance, through 9 for maximum compression with greatest performance impact.
\nZLE is a fast algorithm that only eliminates runs of zeroes.<\/p><\/blockquote>\n- \n

ACL Mode<\/strong><\/p>\n

Passthrough<\/i>\u00a0only updates ACL entries that are related to the file or directory mode.<\/span><\/p>\n
Restricted<\/i>\u00a0does not allow chmod to make changes to files or directories with a non-trivial ACL. An ACL is trivial if it can be fully expressed as a file mode without losing any access rules. Setting the ACL Mode to Restricted is typically used to optimize a dataset for SMB sharing, but can require further optimizations. For example, configuring an rsync task with this dataset could require adding\u00a0<\/span>–no-perms<\/i>\u00a0in the task\u00a0<\/span>Auxiliary Parameters<\/i>\u00a0field.<\/span><\/p><\/blockquote>\n

Metadata (Special) Small Block Size<\/strong><\/p>\n
This value represents the threshold block size for including small file blocks into the special allocation class. Blocks smaller than or equal to this value will be assigned to the special allocation class while greater blocks will be assigned to the regular class. Valid values are zero or a power of two from 512B up to 1M. The default size is 0 which means no small file blocks will be allocated in the special class. Before setting this property, a special class vdev must be added to the pool. See zpool(8) for more details on the special allocation<\/p><\/blockquote>\n
