comment btrfs: Looking for experience on btrfs error modes on bad sectors / read errors / medium erros
I'm testing it right now on a few broken drives so I guess in a few weeks I can report back...

I'll give you the bounty but don't accept the answer. I hope that's okay.

comment btrfs: Looking for experience on btrfs error modes on bad sectors / read errors / medium erros
This place is frustrating sometimes. Did you read my question? RAID does not make sense for Hadoop - so JBOD is the only choice. It's a question about that exact problem. Metadata replication on a single disk or multiple disks and how this works in practice. I know that I can buy more disks. Sorry...

comment Why is Ubuntu/Linux /proc/mounts lying to me?
Thanks! That's it. The nagios script is appearently buggy.

comment Does this SMART selftest indicate a failing drive?
@cstamas: Can also agree that your answer is spot on - if a drive survives a full run of badblocks -w (3x writing, 3x reading) without creating new bad sectors I'll keep it. Otherwise it's just too broken to be used somewhere.

comment Check nginx active connection without HttpStubStatusModule
Did you consider checking only for established connections? e.g. $ sudo netstat -antp | grep ESTABLISHED | grep nginx

comment PHP-FPM using 40% CPU for a Single Request
to clarify: You can either use W3TC with a APC/memcache backend or drop W3TC and use the Wordpress plugins directly. I've made the experience that using the plugins directly is in the end more hassle free and slightly faster but things may have changed in the meantime (spend some time on this problem 1-2years ago)

comment PHP-FPM using 40% CPU for a Single Request
It really depends on your site and what you want to accomplish but I'd safe memory for PHP/Wordpress and use static files or pages (It's still fast enough because the OS puts often used files in RAM anyway) and use the memory for MySQL and APC/memcache that get's read and written to more often. You should also configure fastcgi_cache to only cache a page if it request more than 3-4 times. Saves a lot of IO and the site is still safe for reddit/news.yc

comment PHP-FPM using 40% CPU for a Single Request
Some thoughts: Use memcache or APC for W3TC - there is also a plugin for using APC as object cache provider. Using disk here does not make much sense, because there a lot of reads and writes (multiple per second on my installation pic. There is a plugin called nginx_helper that adds purge support for fastcgi_cache, never used that through. Finding a good cache_key can be difficult. I'd use MySQL query cache + object cache with either APC/memcache. DB-Cache is not so important

comment Using iptables on the host for Virtualbox instances
I'm a noob regarding iptables. I assume this way I can also filter outgoing traffic? e.g. based on the internal source port?

comment Apache bottle neck
Take a look at the tutorial. php-fpm has a lot of config files and options. There is some documentation here: php-fpm.org/wiki/Main_Page (probably outdated) and here php.net/manual/en/install.fpm.php. How hard? I think it depends on your application. If fcgid works for you I would not worry to switch. Plesk and Cpanel Integration does not exist, so you are on your own with php-fpm. The results you get could be caused by the ab benchmarking tool and not mod_fcgid. So don't switch if it's not critical.

comment Apache bottle neck
Probably not what you are looking for but If you can replace mod_fcgid with php-fpm I would use the latter. Gives me more reliable results. It works with mod_fastcgi tutorial or omit Apache and use php-fpm directly with nginx.

comment RAID-5 or RAID-6 - is RAID-5 really that bad?
I did not want to use a hotspare, then I also could use RAID6 directly. Having a hotspare does also not help me with the potential rebuild bit-errors or does it?
