Instructions

Følg disse trin for at kontrollere og/eller ændre indstillingerne for SVM vm.overcommit:

1. Log på SVM ved hjælp af SSH som rod

2. Kør cat /etc/sysctl.conf | grep "vm.overcommit"
Ex. 
[root@sds-node logs]# cat /etc/sysctl.conf | grep "vm.overcommit"
vm.overcommit_memory = 2
vm.overcommit_ratio = 50

3, Kør følgende kommandoer 
sed -i 's/vm\.overcommit_memory = .*/vm\.overcommit_memory = 2/g' /etc/sysctl.conf
sed -i 's/vm\.overcommit_ratio = .*/vm\.overcommit_ratio = 100/g' /etc/sysctl.conf
sysctl -p

Validering 
[root@sds-node logs]# cat /etc/sysctl.conf | grep "vm.overcommit"
vm.overcommit_memory = 2
vm.overcommit_ratio = 100

Gentag disse trin på alle SVM'er i miljøet for at sikre, at de er indstillet til de anbefalede indstillinger for bedste praksis. Du behøver ikke at sætte sikkerhedsdatabladet i vedligeholdelsestilstand for at udføre denne handling.
