comment How can I directly read data from a file in Linux without using the filesystem cache?
@ewwhite You're right. I'd like to hear the explanation. But even if he has a perfect reason, I'm going to tell him to stay away. It's so wrong, I can't even explain.

comment ZFS - Reconnecting a disconnected but fully intact disk
AFAIK when you remove part of a stripe configuration, the whole pool stops working. No reads or writes will work. If you return the disk, it will work again. Removing and reattaching part of redundant vdev should result in resilver.

comment Nginx proxy_pass and redirect
You probably shouldn't make long story short. Quite the opposite. If your upstream is set like upstream blog { ip:8888; } What URL do you enter and what exactly happens (include error message, response code, whatever), or what do you expect to happen?

What do you want the input, output pair be and what it is now? I'm having hard time understanding what are you trying to accomplish.

comment haproxy-varnish can't reach 6k requests
Just a few Qs ... Why HAProxy in front of Varnish? What are the loads during test? How are you testing? Using keep-alives? What hardware? Does the test pass Accept-Encoding: gzip? What is the cache hit rate?

comment Optimize Linux file system for reading ~500M small files
If it's just a file sharing, I'd go with FreeBSD/ZFS, or something Illumos based and a huge amount of memory. Maybe SSD for L2ARC.

comment How does HA / failover work?
"how to provide HA of that load balancer?", that's what I'm talking about at the end of my answer. It is easy to set up Active/Passive (VRRP) solution for 2-nodes with low load. It gets much more tricky with 10 nodes. Especially if you do not want asymmetric load.

comment best way to deal with 6 TB hard disks
Well, then go ahead, wipe the disks, install OS afresh setting up one large partition as RAID0. As far as I remember, Ubuntu installer does allow you to do that (maybe with small root or boot partition). Debian won't be too different. Really the problem is, that this site is supposed to be about doing things 'the right way for business'. And as far as your question and use of webmin goes, you're not a pro. That's why everyone keeps warning you off the RAID0 path (the wrong path for most IT business).

comment best way to deal with 6 TB hard disks
no, that will not fit. you have two raids one can contain 1.7TB and another 1TB. you would need to destroy those (meaning removing all data), and make RAID0 out of these and mount it under /var/www/html. but you quadruple the chance of data loss in case of disk failure. and depending on where those raids are mounted, that might make your system unusable.
