Oh and another one - what is your CPU ticket standing on the instance?

comment NGINX HTTPS Reverse Proxy - Fast TTFB but low concurrency
Like 'Is CPU load high? Do you see any other bottlenecks?' ... or a new one ... are you running ab on the same machine?

comment NGINX HTTPS Reverse Proxy - Fast TTFB but low concurrency
You need to provide way more information ... What/how you are benchmarking? What software are you using? How does the traffic affect the server? Is CPU load high? Do you see any other bottlenecks? What hardware is that on? And maybe something else I didn't realize yet.

comment file /dev/adm taking too much space disk
btw. I don't think it would crash anything, but it could trash your console. Consoles are generally not good at displaying binary stuff and can get confused a lot. strings is a great idea as well ...

comment file /dev/adm taking too much space disk
cating the file this large is not a good idea.. head | hexdump -C could be better. file I suggested could help as well. Especially if contents are binary. And just removing the file without actually finding out how it 'happened' is not really a good practice. As it might be a sign of compromised server, or some kind of misconfiguration.

comment file /dev/adm taking too much space disk
Is it a file, or char/block device? ls -al /dev/adm What kind of data is inside? file -s /dev/adm Is it growing?

comment huge traffic from POST 123.249.24.233/POST_ip_port.php
Just a warning. Even though it has become somewhat customary, it usually is not a good security practice running unknown unchecked scripts straight off the web.

comment Backup server with NAS and Bacula
Keep in mind that Bacula, while pretty good software, is rather full-blown backup solution for managing large-scale backup solution and is rather targeted at tapes. It is not exactly easy to setup right at first shot. If you need simple backup solution for one server, get something simpler. I do have no experience with suggested rsnapshot, but can recommend duplicity, which works well for me. (And no, this is not meant as flame-starter).

@MMike1986 RAID1+0 is stripe + mirror. RAID5 is parity, RAID50 is stripe+parity. And what I am saying is, you only get sequential read benefits from RAID0, not RAID1. It's like you had two drives in the array for this purpose.

comment zfs error behind LSI raidcontroller
Well 2 errors on one drive does not make the whole pool unusable even in the event of another drive failing. But it really depends on how you feel about your data. Scrubbing will tell you, if there are any inconsistencies and will bring afront all still undiscovered errors in this and other drives. If you care about your data very much, you probably should scrub regularly. If you can recover from any amount of errors (got backups?), you can skip it.

comment Netfilter : invalid state for proxy through VPN
@Burps I dissected the tcpdump for you. Hopefully it helps, as I'am not sure, I will be able to provide more information on this issue.

comment Netfilter : invalid state for proxy through VPN
@Burps, my apologies, I lost my crystal ball. Please update your question with more information (like the tcpdump of last 5-10 packets - possibly shared through pastebin, if too long), if you desire more detailed answer.

comment How to fix my broken raid10 array
@Rog by the way this is second time something weird happened to your array (first there were two devices #3, now you have superblock gone missing). This really smells fishy and I suspect there is something, or someone, else doing the damage, rather than failed drives. You really should doublecheck everything before breaking it even more.

comment How to fix my broken raid10 array
@Rog I'm sorry to hear that. Try to see what's wrong with the drive. But missing superblock really sounds like it has been wiped by something, or that the drive is completely dead. With RAID10 and NEAR layout you may be lucky enough and get it to work with just two drives. But if you are not, I'd probably go for a professional recovery, if the data is of value. It will be costly, but you may get some data. If you start messing around, you may destroy whats left of your data.
