comment What “access rights” could be blocking access to a gitlab repository?
I had the same problem as Caleb, and I also found by myself that to make it work one need to set a shell instead of /bin/{false,true,nologin}. But actually the user is created without shell on purpose during installation (see: gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/install/…) sudo adduser --disabled-login --gecos 'GitLab' git. So it ought to work without a shell. I'm still looking for another solution.

comment slow copy due to disk write issue
@shantanuo is a UPS not possible in your case? With the disk cache reactivated, could you provide the info asked in the 3rd comment?

comment slow copy due to disk write issue
@shantanuo disabling write caching can have a non predictable effect on application depending on the "write profile" they have. So this is not depending on the OS (here CentOS) but on the type of update that the application performs. Why would you disable "write cache"? the only scenario I can think of is that your HDD are in RAID but without a battery-backed RAID controller.

comment slow copy due to disk write issue
I am not sure I understand your last comment @shantanuo. Did you disable the "write cache" of your HDD? Or are you referering to my command using drop_caches? If you disabled the "write cache" of the disks (so that the disk does not use its internal read/write buffer) then of course this has an adverse effect on performance.

comment Measuring disk usage
I don't know what is "fair". But if someones does lots of small random reads, he could saturate the capacity of the storage in terms of IO, eventhough that he might reads less MBytes than a user reading a big chunk of contiguous data. What you want to bill and what you want to "limit" to keep all of your users happy is a commercial decision in the end, for which I have no particular thinking.

comment Custome page when Apache Server is down
@HBruijn is correct. Basically Apache listen on port 80. But if you stop Apache, no one is listening on port 80. So when a request arrives on this port, your Operating System is simply rejecting it as no service is listening.

comment Measuring disk usage
Technically disk usage measured in terms of IOPS and bytes r/w is good but sometimes not enough, or does not give you the right picture (see for example this article: mysqlperformanceblog.com/2014/06/25/…). But from a commercial point of view IOPS and throughput used could be enough as the goal is to bill those that are using an excessive share of resources so that the sharing of these resources between VMs is viable.

comment How to clear cache in centos remote server?
On which of the command are you getting permission denied. In addition, caches should not block you from installing applications. So you probably have another problem preventing you for installing apps.
