NDB Cluster Configuration Files nodes are restarting anywhere in the cluster, use  MaxDiskWriteSpeed . The minimum speed for disk writes by all LCPs and backup operations can be adjusted by setting  MinDiskWriteSpeed . Set the maximum rate for writing to disk, in bytes per second, by local checkpoints and backup operations while this data node is restarting. For setting the maximum rate of disk writes allowed while other data nodes are restarting, use MaxDiskWriteSpeedOtherNodeRestart . For setting the maximum rate of disk writes allowed when no data nodes are restarting anywhere in the cluster, use  MaxDiskWriteSpeed . The minimum speed for disk writes by all LCPs and backup operations can be adjusted by setting  MinDiskWriteSpeed . • MaxDiskWriteSpeedOwnRestart Version (or later) NDB 8.0.13 Type or units numeric Default 200M Range 1M - 1024G Restart Type S (NDB 8.0.13) Version (or later) NDB 8.0.13 Type or units numeric Default 10M Range 1M - 1024G Restart Type S (NDB 8.0.13) Set the minimum rate for writing to disk, in bytes per second, by local checkpoints and backup operations. The maximum rates of disk writes allowed for LCPs and backups under various conditions are adjustable using the parameters  MaxDiskWriteSpeed ,  MaxDiskWriteSpeedOwnRestart , and MaxDiskWriteSpeedOtherNodeRestart . See the descriptions of these parameters for more information. This parameter specifies how long data nodes wait for a response from the arbitrator to an arbitration message. If this is exceeded, the network is assumed to have split. The default value is 7500 milliseconds (7.5 seconds). • MinDiskWriteSpeed • ArbitrationTimeout • Arbitration Version (or later) NDB 8.0.13 Type or units milliseconds Default 7500 Range 10 - 4294967039 (0xFFFFFEFF) Restart Type N (NDB 8.0.13) Version (or later) NDB 8.0.13 4112
