immediately, the cluster status is overcommitedPart 5. DemoWell, finally to the routine of the people look forward to the demo, if only say the algorithm does not carry out a demonstration, this concept is indeed more abstract,Scenario: 4-node cluster with host 4x 32GB hosts. The system retains 9GB of memory. 64MB of Hyper-V monitoring requires memory to not participate in the calculation (completely the diagram is my convenience), Cluster Reserve (R) is 2, the cluster is composed of, for examp

This parameter is set to bytes, the recommended setting range should not exceed 3/5 of the operating system disposable memory, such as your operating system can control 8GB of memory, then the recommended setting value is 5GB, that is 5242880k, 5120MB, 5GB. In the configuration of large hours, Redis supports a variety of units shorthand, that is, 1GB 1Gb 1gB is a meaning. If you do not set this para

create a corresponding RBD block for kubernetes storage. Before you create a block device, you need to create a storage pool, and Ceph provides a default storage pool called RBD. We then create a kube store dedicated to storing the block devices used by kubernetes, and subsequent operations are performed on Client-node:Ceph OSD Pool Create Kube #后面两个100分别为pg-num and Pgp-numCreate an image file in the Kube storage pool called Mysql-sonar, which is 5GB
Installing a Linux system on a computer, partitioning the hard disk is a very important step, and here are a few of the partitioning schemes.Scenario 1/: Recommended size is above 5GB.Swap: Swap partition, the recommended size is one or more times of physical memory.Scenario 2/boot: Used to store the Linux system boot-related programs, such as boot loader, etc., the recommended size is 200MB./: The root directory of the Linux system, all directories are hung under this directory, the recommended
Diskgenius is a very useful partition tool, however, in addition to the computer, hard disk partition, Diskgenius function There are many, for example, to help the hard drive to find the missing partition. So how did Diskgenius do it? Let's take a look at today's use of Diskgenius to find a way to lose space on the hard drive!

Ghost is a backup and restore data tool software, it can partition the hard disk, or the entire hard disk into image files back down, when needed to restore the past. One of the advantages of using ghost Backup files is that you can back up or restore a 5GB file partition in about 10 minutes, and the advantage of this is that a very high compression ratio can be used to make a partition of 5GB files into a
backup your data, as shown in the following illustration:
icloud automatically back up data
By default we can back up the maximum data 5GB, if you need to have a larger Apple icloud storage space, you need to upgrade the cloud storage space, in general, Apple provides a total of 5GB is sufficient.
⒊) Then we go to "Manage storage space", and then we see a space for displaying backups and messag
you set the parameter use_indirect_buffers=true, you will only be able to define and use a single database block size and block buffer (as in a 9i release number), so if the default database block size is 4k, 8k, or otherwise, set the Db_2k_ Cache_size is not allowed. Next, you need to set the appropriate awe_window_memory parameter values for Oracle_home in the registry, which means that, under hkey_local_machine\ SOFTWARE\ORACLE\HOME0, this parameter specifies the number of bytes, if not set
