Hi, I'm unable to run this version. It complains about Transparent Huge Pages... even though I believe they are disabled...

Example 1 - Centos 7

[simon@centos7vma voltdb-ent-5.5]$ cat /etc/centos-release
CentOS Linux release 7.1.1503 (Core)
[simon@centos7vma voltdb-ent-5.5]$ cat /sys/kernel/mm/transparent_hugepage/enabled
always madvise [never]
[simon@centos7vma voltdb-ent-5.5]$ ./bin/voltdb create
ERROR: The kernel is configured to use transparent huge pages (THP). This is not supported when running VoltDB. See the VoltDB Administrator's Guide for instructions for disabling THP.

Example 2 - Dockerized Debian

root@volt1:~# cat /etc/debian_version
8.1
root@volt1:~# cat /sys/kernel/mm/transparent_hugepage/enabled
always madvise [never]
root@volt1:~# voltdb create
ERROR: The kernel is configured to use transparent huge pages (THP). This is not supported when running VoltDB. See the VoltDB Administrator's Guide for instructions for disabling THP.

Any ideas?

Thanks Simon

simon.stone,

Please take a look at disabling transparent huge pages. Check the setting for defrag and ensure its' also set to never.
