Optimize availability and performance by following the guidelines in this section.
ext4 filesystems when operating on Linux or Solaris platforms. The
ext4 filesystem supports preallocation, which benefits disk startup performance. If you are using
ext3 filesystems in latency-sensitive environments with high write throughput, you can improve disk startup performance by setting the
maxOplogSize (see the
DiskStoreFactory.setMaxOplogSize) to a value lower than the default 1 GB and by deactivating preallocation by specifying the system property
gemfire.preAllocateDisk=false upon VMware GemFire process startup.
shutdown command. This is an ordered shutdown that positions your disk stores for a faster startup.
disk-usage-critical-percentage) for the disk. By default, these are set to 80% for warning and 99% for errors that will shut down the cache.
backup disk-store command.
By default, the disk stores are recovered in parallel when the cluster restarts. Parallel disk store recovery is usually faster than sequential disk store recovery. If you require sequential disk store recovery, start your servers by setting the system property:
geode.parallelDiskStoreRecovery=false. For example, using gfsh to start your servers:
start server --name=server1 --J=-Dgeode.parallelDiskStoreRecovery=false
