comment How to Read the haproxy Stats Page
@Willy of course they look clear to you, you made the app! :) With the copy/paste I meant that it's the same thing as 2 rows before it. Anyway, thanks for the info.

comment grub crc error after decompressing linux
It used to be in sync but now I have kicked the drive out of the array. I'm trying to use separate /boot partitions for each drive and keep raid just for /

I added the 2nd hard drive last week, but didn't had to test it until yesterday.

comment grub crc error after decompressing linux
Well, considering the scenario where sda fails, I remove it and sdb now becomes sda, so hd1 is hd0, I don't need to modify that. I also don't need the root= because it already knows where the root is -> root (hd0,0). The problem is that it finds vmlinuz and initrd, starts decompressing but gives that crc error.

comment 100% iowait + drive faults in dmesg
I changed my mind, I see that read/writes are fairly equal - sda 153 sdb 143 for writes and sda 32 sdb 25 for reads with some spikes along the way, but I guess that's normal given the fact that sdb has to synchronize after sda. Right?

comment 100% iowait + drive faults in dmesg
Start/stop count for sda is 26 and for sdb 8. I thought about failing sda, but then again I need redundancy, and if I re-add sda it would take fairly much to resync.

comment 100% iowait + drive faults in dmesg
I changed the SATA cable and then I moved the HDD to another slot as that one seemed suspicious (it took some time to detect my HDD drives) and afterward it was ok. I now have in atop: sda busy 55%, sdb busy 23%. So I still don't think it is entirely solved.

Yes, I do have a swap partition set up. But there is no swapping being made. In fact, I am now watching munin graphs and no swapping has been made for 2 days, which is kind of weird because the history shows a constant use of swap.

I was about to mention if a faulty cable could be guilty. I will replace the current cable and see if anything changes.

I have updated my primary post with some smartctl output. As you may see, no errors/pending sectors. It is also a fairly new drive (~1 month old)

Yes, software raid. I checked mdstat and they are in sync, none was kicked off from the array. It is weird because I thought I should see md1_raid1 in top as it eats my resources away, but it is kind of idle. Instead, the first 3 apps in top are my web ones - httpd, java, varnish. Also, smartctl reports no errors whatsover.

I don't think that a copy/paste is very helpful.

Ok, so I'll keep my eyes on the Session columns. Can you elaborate a bit on Session rate?

comment Port-forwarding on livebox to router
There shouldn't be any problem with the Windows server. Suppose you forward port 80 to the Server and you want the first 2000 ports forwarded to Netgear, just specify 1-79 as the first range and 81-2000 as the second range. These are two separate entries.

i just searched it and it doesn't seem to be a way. i found puttycm which is for $indows, but it needs many improvements. clusterssh would had been great, indeed.

that's not quite a great idea.
