Bruno Lavoie updated AMBARI-21846: ---------------------------------- Summary: Transparent Huge Pages check using wrong file for CentOS 7 (was: Transparent Huge Pages check using wrong file CentOS 7) > Transparent Huge Pages check using wrong file for CentOS 7 > ---------------------------------------------------------- > > Key: AMBARI-21846 > URL: https://issues.apache.org/jira/browse/AMBARI-21846 > Project: Ambari > Issue Type: Bug > Components: ambari-agent > Environment: CentOS 7.x > Ambari 2.5.1 - Hortonworks > Reporter: Bruno Lavoie > Priority: Minor > > In ambari_agent/HostInfo.py, the file used to check Transparent Huge Pages > for RedHat family is: /sys/kernel/mm/redhat_transparent_hugepage/enabled > But it appears to be /sys/kernel/mm/transparent_hugepage/enabled for CentOS 7. > {code} > # cat /etc/redhat-release > CentOS Linux release 7.3.1611 (Core) > # cat /sys/kernel/mm/redhat_transparent_hugepage/enabled > cat: /sys/kernel/mm/redhat_transparent_hugepage/enabled: No such file or > directory > # cat /sys/kernel/mm/transparent_hugepage/enabled > [always] madvise never > {code} > No warnings when configuring hosts for a fresh cluster while I didn't > disabled THP. Found it suspect and stumbled into this issue. > Maybe the code must be more tailored for managing CentOS vs RedHat. > I don't have any RHEL to check if it changed there too. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
