| up_the_irons | appears 1 VPS has been recovered successfully and moved to kvr25. I almost can't believe my eyes...
24 to go... up_the_irons wonders where the 24/7 coffee is at the data center... | [02:43] | |
| mercutio | sound laborious
if it gets bad ddrescue can be handy it keeps trying to read blocks, and if it can't then it zero's them which can be better than having no data oh it says it odesn't write zeros Ddrescue does not write zeros to the output when it finds bad sectors in the input, and does not truncate the output file if not asked to. So, every time you run it on the same output file, it tries to fill in the gaps without wiping out the data already rescued. oh maybe it uses sparse files? Copying this partition with normal Un*x tools like cat or dd will fail, as those tools abort on error. dd_rescue instead will try to read and if it fails, it will go on with the next sectors. The output file naturally will have holes in it, of course. You can write a log file, to see, where all these errors are located. ahh | [02:46] | |
| up_the_irons | jlgaddis: you're probably sleeping, but if not, check your vps. it just came back up. migrated to host kvr25. I did like 10 forced fsck's and they all passed, but i'm still weary until a customer says, "yep, it's all there!" | [02:49] | |
| jlgaddis | roger, standby | [02:49] | |
| up_the_irons | w00t you're awak
*awake | [02:49] | |
| jlgaddis | looks good so far | [02:50] | |
| up_the_irons | mercutio: yeah, i've used ddrescue before; it's a neat tool | [02:50] | |
| jlgaddis | web server is up, sites accessible, ssh'd in w/o issue | [02:50] | |
| up_the_irons | wow
that's awesome the RAID was spitting out errors like it was on fire | [02:50] | |
| jlgaddis | nothing abnormal in dmesg | [02:51] | |
| up_the_irons | i couldn't dd your image until now... the raid was going down in a ball of flames. but by some stroke of luck, the raid *finally* rebuilt. and now i did not get any I/O errors when dd'ing your image.
anyway, not gonna look a gift horse in the mouth. 2 down, 23 VMs to go... | [02:52] | |
| jlgaddis | awesome
everything looks good, afaict | [02:54] | |
| up_the_irons | jlgaddis: very glad to hear | [02:54] | |
| jlgaddis | me too, tyvm! | [02:55] | |
| mercutio | hmm maybe i should backup my vps :) | [02:55] | |
| jlgaddis | yeah, i hadn't done a full off-site since 11-jun. about to run one now. =) | [02:56] | |

| up_the_irons | mercutio: backups are a good idea :) | [03:01] | |
| mercutio | yeah i'm doing a tarball now
there's not a lot on there but still.. well i'm actually doing bzip2... i hope it's ok using quite a bit of cpu.. i figure it's the middle of the night in the US anyway | [03:01] | |
| jlgaddis | ... full backup from los angeles to chicago at 100 mbps ... =) | [03:05] | |
| mercutio | i'm getting 15 megabit
damn you :) i think i'm cpu bound maybe i should backup to chicago and not compress | [03:05] | |
| jlgaddis | i'm using duplicity for the backup, it's doing compression and encryption on the fly, fwiw | [03:09] | |
| mercutio | oh?
i'm using ssh and tar -C/ -vcjf - back to new zealand though and it seems to go 2 to 16 megabit | [03:09] | |
| jlgaddis | physics and tcp bandwidth/delay product =) | [03:10] | |
| mercutio | hmm
it shouldn't be it can do faster than that with http i think it's the bzip2 and it could also be doing lots of small files like /usr/src has openbsd source code in it with lots and lots of file names like it's at 22 megabit now it's doing my 200 mb test download (which i really don't need to bakcup) it's nearly done aynway | [03:11] | |
| up_the_irons | LOL, now that kvr04 has been rebooted, and my 984 days of uptime has been thwarted, I can *finally* replace that failed DIMM from almost 3 years ago...
wish i knew a good way to find out which stick is bad | [03:15] | |
| jlgaddis | lol
trial and error | [03:15] | |
| mercutio | memtest
and count | [03:20] | |
| jlgaddis | yay, full backup done | [03:20] | |
| mercutio | usually odd first stick even second stick
then memory location | [03:21] | |
| jlgaddis | now just need to automate nightlys | [03:21] | |
| mercutio | but i had dead memory on a laptop once and i had no idea which was first or second stick
took out a stick got way more errors and i was like YAY it must be the other stick | [03:22] | |
| jlgaddis | now, bedtime. =) great job garry, thanks again! | [03:22] | |
| mercutio | oh unless it auto takes it out of the pool of memory | [03:23] | |
| up_the_irons | jlgaddis: np!
jlgaddis: ty for your patience :) | [03:37] | |

| ryk | help
i dun made a booboo oh wait ryk creates support ticket instead | [09:55] | |
| arenlor | ryk: What type of mistake? | [09:58] | |
| ryk | well, openbsd allows you to choose to redict local console output to com1 serial in the installer, which i chose | [09:58] | |
| arenlor | ryk: Try the serial console? | [09:59] | |
| ryk | however, i've now found that both the vnc console as well as the serial console only become available for input after the boot | [09:59] | |
| *** | heavysixer has joined #arpnetworks
ChanServ sets mode: +o heavysixer | [09:59] | |
| ryk | in other words, i can't get anything in to the bootloader prompt before it's too late and starts booting
from either console i just need them to put the ISO in is all to change it, since I'm currently locked out of the vps and wanted to get into single user mode but now realized i can't due to the above. | [09:59] | |
| toddf | vnc console you're in a race against time to connect and hit 'control' on your keyboard
the iso should be in the cdrom you have some time to press an f11 key or somesuch to get to the iso if you connect the vnc at the right instant | [10:02] | |
| ryk | ooh i got it this time! | [10:02] | |
| toddf | but if you get that timing right you should also be able to hold control on your keyboard to bypass the boot.conf ;-)
console starts on vga, if you put in boot.conf 'set tty com1' then you're not going to see anything on com0 | [10:02] | |
| ryk | there is a com0? | [10:04] | |
| toddf | the serial console at arpnetworks is com0 | [10:04] | |
| ryk | ah | [10:04] | |
| toddf | why would the hardware emulate then discard a whole com port? | [10:04] | |
| ryk | toddf: would you recommend just always keeping it on vga? | [10:05] | |
| toddf | I find ssh + serial console much easier to interact with than vnc. it truly depends on if you find it more conveneient or not. for me cutting/pasting the console is awesome, any ddb> prompts easy to interact with and copy, not to mention I have a remote ssh key from a remote conserver capable of logging the console of my vps. try that with vnc! heh | [10:06] | |
| ryk | yeah i use the serial console iwth my xen vps provider, it works well because it never drops off | [10:07] | |
| toddf | it used to drop off everytime up_the_irons made a conserver config change, but now that -HUP is in use, ... ;-) | [10:07] | |
| ryk | this just seems tricker during boot | [10:07] | |
| toddf | trickier how? if you don't mind more delay you can always 'set timeout 120' in /etc/boot.conf to give you 2 minutes to hit console before it boots regardless if its serial or vnc | [10:08] | |
| ryk | is that 2 minutes of it sitting at the boot> prompt? | [10:09] | |
