| fIorz | up_the_irons: any chance you could provision the replacement VM in parallel with the old one still running (with temporary addresses, v6 would be sufficient)? the old one is still running fine, so I could restore my backup and then cut over once that's done | [04:42] |
| up_the_irons | fIorz: should be doable. just tell me which IPv6 I should assign. | [04:43] |
| fIorz | up_the_irons: you mean from my subnet? just take a random one, chances are negligible that you'll hit one that's in use? ;-) | [04:46] |
| up_the_irons | i suppose you're right ;)
OK, I have 1 VPS ahead of you, then I'll work on yours | [04:48] |
| fIorz | sure, it's not particularly urgent as the old vm seems to be working just fine so far, and I'll be afk in a moment anyway ... | [04:50] |
| up_the_irons | ok
another customer said a similar thing, that the VM was running fine. But we did a ZFS snapshot of all VMs on that host and tried to transfer the data off, and OH MAN, was it corruption city. 'zpool -v status' reports your volume as affected. | [04:50] |
| fIorz | well, it's mostly a tunnel endpoint, openvpn is probably in the pagecache, so chances are you could more or less remove the disk completely and it would still work fine ;-) | [04:55] |
| up_the_irons | hahaha
fair enough | [04:55] |
| fIorz | but, yeah, bad luck indeed with two disks failing at the same time ... same manufacturer/manufacturing batch? | [04:58] |
| up_the_irons | it all came as a set. a bunch of HP disks in a 25-bay server. _really_ weird the failures were from the same raidz group.
makes me want to put a Ceph cluster out in Frankfurt alas the initial server count needed is high | [05:06] |

| mrsaint_ | MIne just froze right now when tried to do ps aux :) | [05:28] |
| up_the_irons | i'm not surprised | [05:28] |
| mrsaint_ | or it died even
yeppers. died hehe oh well.. wanted to backup bgpd.conf | [05:29] |
| *** | mrsaint_ is now known as mrsaint | [05:30] |
| mrsaint | yeah timeout wait for disk kinda.. kernel outputs.
want me to reply to email I guess? | [05:31] |
| up_the_irons | if you feel you're done with it and there's no more saving data, you can just tell me here | [05:32] |
| mrsaint | Well I cant save any data as it died :)
up_the_irons: but if you want you can put it to centos6.7? or 6 :) hangon.. I just got in again. let me rsync what I need. done :) | [05:32] |
| up_the_irons | crap, I don't have the 6.x line in our templates in Frankfurt
I can work on that later today if you don't mind | [05:37] |
| mrsaint | ah ok. Np.
Ill shutdown bgp while its having related issues so i dont run into more diskusage perhaps. | [05:38] |
| up_the_irons | ok | [05:41] |

no problem | [07:12] |
| mrsaint | up_the_irons: now syncing 5000 domains again :) | [07:16] |
| up_the_irons | what do you do? :)
is that for like.. dns.. or? think it's time for me to finally sleep... g'nite all | [07:16] |

| mrsaint | up_the_irons: yeah dns and webanycasted service. | [10:01] |
| ................. (idle for 1h24mn) | ||
| plett | mrsaint: Anycast web stuff? How stable do you find the internet for that? Many problems with TCP sessions dying because they change routing? | [11:25] |
| mrsaint | plett: works just fine.. static content and varnish that do cache alot.
and I choose my providers for my servers with care. Specially take them with direct connects to either me or my providers.. | [11:31] |
| mercutio | there's actually a lot less varying with routes than there used to be.
and a lot of them come from brief outages where web page not loading right sucks anyway and people reload or go somewhere else | [11:39] |
| mrsaint | yeah.. And would be same problem anycasted or not.. Only times I would have connection problem would be when the node cant reach backend and it has not yet happend.. :) | [11:42] |
| mercutio | yeah that seemse to be normal cloudflare issue
the node can't reach the backend (cloudflare are anycasting tcp too) | [11:43] |
| mrsaint | yeah | [11:43] |
| mercutio | reddit is the site i most have issues with
but their backend usually responds but not positively :) | [11:44] |
| mrsaint | my own site is dynamic but alot of it is static so works fine anyway. so we see. I only have gamesites and their png/gif content sofar.
but the dns works lovely really nice.. | [11:44] |
| plett | Yeah, anycast dns is a good solution. I'm not sold on doing it for web traffic though :) | [11:47] |
| mercutio | i'm not sold on tcp for web traffic
with people expecting 2 second load times etc, slow resend etc delays really hurts and it'd be better if the client knew about multiple places to source the same data from, and to have good web caches etc | [11:48] |
| plett | mercutio: It's fine, just don't live somewhere a long RTT away from the web server ;) | [11:50] |
| mercutio | linux decreasing the initial timeout from 3 seconds to 1 seconds really helps
but yeah high rtt connections really don't want packet loss but then you end up with 1 second+ pings on 3g because they don't want to drop packets | [11:50] |
| plett | 3G networks here are typically 200ms ping times. 4G are closer to 10 or 20ms | [11:51] |
| mercutio | dc hsdpa or whatever is around 60 to 80 msec
but often there's some congestion i found it went up when there was a power cut.. which is when i wanted to use it, and it was 1+ second. i tried a few random times afterwards and wasn't nearly as bad 4g is here now at least. | [11:52] |
| mrsaint | plett: if you have a web you want to try you can try it for free if you wish. Prefer backend at a location where I have good connectivity to tho. To secure uptime. | [11:55] |

| fIorz | up_the_irons: re ceph: yeah, probably the best solution to that problem--but be careful with the crypto, it's terrible (unless they have redesigned that in the last year or so since when I did a rough review of the code) | [18:20] |
| ...... (idle for 27mn) | ||
| up_the_irons | we aren't using the crypto in ceph | [18:47] |
