log_disk_size specifies the size of the log disk where the REDO logs are stored.
Note
This parameter is introduced since OceanBase Database V4.0.0.
| Parameter | Description |
|---|---|
| Type | Capacity |
| Default value | 0 |
| Value range | [0M, +∞) |
| Effective upon restart of OBServer node | No |
Note
- If you set this parameter to 0, the log disk space is allocated based on the value of
log_disk_percentage. For more information aboutlog_disk_percentage, see log_disk_percentage. - When an OBServer node is started, a specified log disk space is allocated. For example, if
log_disk_sizeis set to 100G, 100 GB of log disk space is allocated for the log file pool when the OBServer node is started for the first time. - When you create a tenant unit on an OBServer node, sufficient log disk space is reserved for the unit. If the remaining local log disk space (total available log disk space - allocated space) is not enough, the tenant unit cannot be created.
