Comments:
<0> to the RAID they are like partitions.
<1> so..you have 1 SAN with many disks, say 16, and 8 of the disks are on LUN 1 and 8 are on LUN 2 ... and your host things you have 2 SANS ?
<0> so one big RAID partitioned (or divided) into 8 LUNs could be used as the drives for 8 systems.
<2> headmonkey: usually the disks are grouped together and you can make LUNs within those groups
<1> well how could you have the SAN automatically size the LUNS ? thats like having linux automatically size your partitions....it can only make a guess or provide a default...it cant read your mind as to the storage requirements of the software
<0> headmonkey: works really nice with fiber-scsi.
<0> headmonkey: nope.
<0> well it could make equal sizes by default.
<0> but thats seldom used.
<1> although you would think they would have some type of emergency reallocationf feature
<1> so that if a LUN was filled, it could be allowed to steal space from another
<1> until you can fix the problem
<0> well high end raid controllers often have features for adding drives
<1> or does the LUN sit above the raid ?
<2> headmonkey: they do
<0> headmonkey: it can.
<1> it could still be done
<2> headmonkey: clariions with rev > r16 can do lun migration
<0> on some you can make it one big RAID then subdivide the LUNs.
<1> as long as you have control over the raid, and didnt just buy someones closed setup
<0> for others you make several RAIDS each with their own LUN
<0> depends on the system.
<1> just throw all that **** out and use AFS ;)
<2> headmonkey: some people do that. they make LUNs, then they bind them together at the host side
<0> i once did a system with 8 hosts all sharing one fiber RAID equally divided. each with their own LUN
<0> as the boot drive.
<1> its worked for google ;)
<0> it was insanely fast.
<1> i would imagine if you had a nice ethernet switch, gigabit ethernet in each box, a couple drives each on their own controller, setup...you could get some crazy speeds out of a distributed fs
<0> latency on gigabit ain't that good.
<0> but if you used myrinet or dolphin ics then maybe.
<1> latency on gigabit ethernet with good hardware should be minimal...as long as you dont need realtime
<0> its not great.
<1> its not bad either ;)
<0> there are better options.
<0> for most uses its fast enough.
<1> there are more expensive, nonstandard, options
<0> for clusters and distributed filesystems...no.
<1> im talking cheap...most bang for the buck...not most bang with unlimited bucks
<0> you can find myrinet for $500 a pci interface + a switch for $16k
<0> its not unlimited.
<0> dolphin ics is switchless
<0> but takes at least 2 pci slots per node
<0> or 3
<0> depending on if you want a 2-d or 3-d map.
<0> although as a neat side effect any node is no more than 2 hops from any other node.
<0> and their driver allows for direct memory injection on the remote node.
<3> hello, how do I find my ip if i can't use ifconfig and i'm not root?
<3> when i'm su'd i can use ifconfig or 'ip address' but i can't do that when i'm not. Is there another way to find my ip address?
<1> kinection_, /proc ?
<3> headmonkey: i'll look in there.
<0> curl -s http://www.whatismyip.com | grep "Your IP" | cut -d \ -f 4
<0> and thats two spaces after the -d
<1> kinection_, you can always check the ifconfig sources as well...its a small prog
<1> kinection_, yeah, if you just need a one time check, use a website
<0> I keep --> alias curip="echo -n \"Current IP: \" && curl -s http://www.whatismyip.com | grep \"Your IP\" | cut -d \ -f 4"
<0> so its one short command away.
<2> lowkey: why use myrinet when you have 4Gbps fiberchannel? :)
<2> lowkey: you can even trunk them together if you need more speed. :)
<1> but the website deal only works if your "on the net"
<1> theres also 10 gb ethernet
<3> lowkey: uh... i meant local eth ip... that looks like quite a line there. Perlish
<2> headmonkey: i bet 10gb ethernet costs more
<4> what good are shared flocks?
<1> linagee, im sure it costs more than 1 gb ethernet ;)
<2> headmonkey: of course. 1gb ethernet is super cheap. lol
<2> headmonkey: especially if you buy a crappy realtek chipset that only gets 20% of the true bandwidth. lol
<1> yeah...intel has a nice low cpu utilization
<1> and linksys switches, and all others at walmart, well, you get what you pay for
<0> kinection_: generally you can run ifconfig, its just not in your path. try /sbin/ifconfig
<1> following, python isnt an option...the server is coded in C and cant slow down....has to be text based...there is a remote admin in gtk
<0> biatches.
<3> lowkey: thanks that worked
<0> kinection_: np
<1> i have a CLI as well, but not really useful for real time monitoring of messages unless you already have messaging that works perfect ;)
<3> lowkey: i was having some trouble finding stuff in /proc.... where would it be if i were to go in there?
<0> kinection_: do you know the base of the ip like 192.168.0.x ?
<1> im at that point where i have to see whats happening....im sure anyone else if they ever use this software will like to see whats happening as well
<0> kinection_: if so do --> grep -r 192\.168\.0
<1> and it is just an option, will eventually be a loaded module, and must be specified by a -i for interactive...its not mandatory
<3> lowkey: ok, thanks, didn't know that grep had a recursive option
<1> i looked at CDK and didnt like it
<3> lowkey: if grep where to find something, would it be possible for it to also return the file which it found it in?
<5> what you mean, like have server with command line, and socket to gui program in pygtk?
<0> kinection_: it will
<1> following, what ?
<3> lowkey: by file i meant the filepath
<0> kinection_: it will read /proc/....
<0> kinection_: have you ever used grep?
<3> lowkey: yea i have used grep
<0> the output is --> /path/to/file:<line in file>
<3> lowkey: nvm.. i found it, i need to add a -H
<3> lowkey: on my box grep doesn't automatically return a file path
<1> how can c not be the right tool ? c is always the right tool ;)
<1> some people just dont get it ;)
<0> bah.
<0> c is generally the wrong tool.
<1> c is the right tool for high performance application development
<1> if you want low performance slug like execution, pick something else ;)
<0> the reality is most applications dont need the execution speed
<0> so the trade off for development speed is worth it.
<1> most apps are data entry database apps, and your right, they dont need c
<1> but your not gonna code novell netware in python
<1> or perl
<1> or php
<1> although, you could port the php to c pretty easily later ;)
<0> a good mechanic doesn't use only one tool.
<0> and a good programmer shouldn't limit himself either.
<1> my compile scripts are in bash ;)
<0> mmmmmmmmmmmmmmmmmmmm homemade chili
<1> no...programmers should pick the tool for the job...i agree
<6> my /boot resides on /dev/hda1. my / resides on /dev/hda3. I want to boot off a floppy, with lilo. How do I set up lilo.conf to do this?
<7> anyone familiar with initrd and grub?
<7> i have bee following a howto on nvidia raid and its not going so well
<1> 37,025 lines ... small project
<7> the only thing i have gotten good at is chrooting to a new environment in gentoo
<6> lol
<7> i can mount, chroot and export prompt like nobodys business
<0> chili is proof that god exists
<0> and that he loves us.
<8> hey, i've been trying to setup MPD on my computer, with ncmpc, i can create playlists, but when i go to play it starts playing and quickly ends (ie: doesn't play) any idea what might be going on? i'm thinking it could be a sound card configuration issue, but Xine and XMMS will play just fine
<9> what do I type in command to boot flash drive?
<10> its a bios setting
<9> hmm
<11> your bios also has to support booting from usb devices
<9> what is a good linux for old laptops?
<8> old laptop linux
<12> argunda slackware :)
<9> ok
<9> have you used it?
<12> yes
<12> and even on and old laptop!
<0> any linux.
<0> just pick the right window manager.
<12> Lokey fedora?
<0> Kevin`: not for a beginner maybe.
<12> fedora worked slow on my 3ghz p4 when I installed it
<0> fedora has the best base setup for playing with the SE security stuff.
<12> (before getting some accelerated drivers)
<0> nvidia?
