Subject: questions about hugetlb usage
Date: Thu, 30 Apr 2015 15:11:34 +0800 [thread overview]
Message-ID: <5541D5A6.7010804@cn.fujitsu.com> (raw)
Hello,
I'm new to cgroups.
I'm not sure whether this is the right place to ask questions about cgroups.
If not, I will be very sorry for disturbing.
Recently, I'm researching the usage of hugetlb.
I have got a problem, but don't know why and how to solve it.

-bash: echo: write error: Invalid argument
It seems I cant write values to hugetlb.2MB.limit_in_bytes
Could anyone give me some advice?
Thanks very much.
