The Cloud Server resources are then increased to the target values while the server is running.<\/p>\n\n\n\n

Additional details<\/h2>\n\n\n\n

Hot resizing system memory is done using virtual memory slots. Each Cloud Server has a fixed number of memory slots. Every time memory is added using hot resized, these slots are used to include the added amount of memory. <\/p>\n\n\n\n

If all slots are already in use, system memory cannot be increased using hot resize until the server is shut down and started. After a full restart, allocated system memory is consolidated and the slots are freed for further hot resizing.<\/p>\n\n\n\n

It’s possible that your Cloud Server’s operating system doesn’t bring all hot resized cores online automatically. <\/p>\n\n\n\n

You can check the currently available CPU count with the following command on Linux systems.<\/p>\n\n\n\n

lscpu<\/code><\/pre>\n\n\n\n
Or press CTRL+SHIFT+ESC<\/tt> on Windows systems to open the Windows Task Manager.<\/p>\n\n\n\n
The easiest way to fix this is to reboot the server. However, on Linux systems, you can use the following script to try to bring CPUs online without a shutdown.<\/p>\n\n\n\n
Copy the following to a new file in a text editor, for example as a file called update-cpu.sh<\/em>.<\/p>\n\n\n\n
#!\/bin\/bash\nfor CPU_DIR in \/sys\/devices\/system\/cpu\/cpu[0-9]*\n  do\n      CPU=${CPU_DIR##*\/}\n      CPU_STATE_FILE=\"${CPU_DIR}\/online\"\n      if [ -f \"${CPU_STATE_FILE}\" ]; then\n            if grep -qx 0 \"${CPU_STATE_FILE}\"; then\n                  echo 1 > \"${CPU_STATE_FILE}\"\n            fi\n      fi\n  done<\/code><\/pre>\n\n\n\n
Save the file and make it executable.<\/p>\n\n\n\n
chmod +x update-cpu.sh<\/code><\/pre>\n\n\n\n
Then run the script by calling it on the command line.<\/p>\n\n\n\n
.\/update-cpu.sh<\/code><\/pre>\n\n\n\n
You should then be able to see all allocated CPU cores. If not, proceed to reboot your Cloud Server.<\/p>\n","protected":false},"featured_media":31080,"comment_status":"open","ping_status":"closed","template":"","community-category":[109,117],"class_list":["post-30793","tutorial","type-tutorial","status-publish","has-post-thumbnail","hentry","community-category-upcloud-services","community-category-automation"],"acf":[],"_links":{"self":[{"href":"https:\/\/studiogo.tech\/upcloudold\/wp-json\/wp\/v2\/tutorial\/30793","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/studiogo.tech\/upcloudold\/wp-json\/wp\/v2\/tutorial"}],"about":[{"href":"https:\/\/studiogo.tech\/upcloudold\/wp-json\/wp\/v2\/types\/tutorial"}],"replies":[{"embeddable":true,"href":"https:\/\/studiogo.tech\/upcloudold\/wp-json\/wp\/v2\/comments?post=30793"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/studiogo.tech\/upcloudold\/wp-json\/wp\/v2\/media\/31080"}],"wp:attachment":[{"href":"https:\/\/studiogo.tech\/upcloudold\/wp-json\/wp\/v2\/media?parent=30793"}],"wp:term":[{"taxonomy":"community-category","embeddable":true,"href":"https:\/\/studiogo.tech\/upcloudold\/wp-json\/wp\/v2\/community-category?post=30793"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
