linux add swap space

When adding Zabbix monitoring to the server, it was found that the server had an error "Lack of free swap space on localhost", by looking to know that when installing the server forgot to divide the swap partition. To reduce the error, now directly divide the swap partition, the following steps:1, create a

the parted command, enter print to view the current partition table, as well as the free space. The start and end values are in megabytes, then calculate how much free space you have and how much space you want to divide into the swap partition.At the parted prompt, enter Mkpartfs part-tyep

directly from the file system without calling from swap. In the early days it was often observed that swap could not exceed 128M, Now our server generally does not exist this problem can swap to 2048M most. The structure of the swap space file is the size of each page of p

= Blocks skips the Ibs*blocks block at the beginning of the read buffer. Obs = bytes Writes bytes bytes At a time, that is, the number of bytes written to the buffer. BS = bytes Sets the number of bytes in the read/write buffer (equal to setting IBS and OBS). CBS = byte convert bytes byte at a time. Count=blocks only copies the input blocks blocks. Example "Add Swap to VPS" Typically only applies to

How to add SWAP partitions for 512 m Centos This tutorial uses centos as an example to add swap memory to a LINUX server with small memory. 1. Create a cache file directory or directly go to the var directory: Cd/var 2. Obtain the

After determining the memory used by the server, we need to increase the swap space by MB.Specific operations:1. dd If =/dev/Zero of =/tmp/swap BS = 1 m COUNT = 1024 M # create a file block of m2. mkswap/tmp/swap # create a swap file3. Swapon/tmp/

. (for example, # fdisk/dev/sdb) remove the swap partition and enter d to delete the swap partition, then add n partitions (the hard disk must have available space when adding the partition, and then use t to change the newly added partition id to 82 (linux

The swap partition in Linux is similar to Windows virtual memory, in the case of insufficient hard disk space, can be created by the swap partition to solve, the following small series to introduce you to the Linux how to create and delete the
