Hello Mathias, > beeing *very* new to linux and storage I directly try to get complex things as AoE understood.... AoE isn`t really that complex. there are much much more complex things on linux/unix - sendmail/apache/samba/mysql are more complex than AoE in orders of magnitude for the end user > Unfortunatly there's no AoE howto for dummys like me - at least I couldn't find one. So first question would be: does anybody on this list jow about a step by step howto? http://www.linuxjournal.com/article/8149 is a good point to start. reading into the documentation inside the aoetools and vblade package at http://sourceforge.net/projects/aoetools will help you, too. then there is google: "+aoe +vblade" > An old machine (one IDE HD with LVM) should be my storage. First question: can I expose an LVM volume via AoE? > I would like to access one LVM volume on this storage from the storage server itseof AND from another machine. you can expose any blockdevice with vblade. there are three variants of vblade: 1st: vblade as part of the aoetools project 2nd: vblade-kernel at http://lpk.com.price.ru/~lelik/AoE/ 3rd: kvblade from coraid - to be released (hopefully) actually, it seems to be a problem to re-use AoE-storage on localhost. it simply doesn't seem to work at the moment. i gave up trying to get this run. > # /usr/sbin/vblade 1 0 eth0 /dev/hda2 > ioctl returned 0 > 4194892800 bytes > pid 12014: e1.0, 8193150 sectors > > and nothing more happened... is that normal) yes! you startet the AoE "server". now it is just sitting there and "listening" for AoE client machines (i.e. linux client with AoE driver loaded). If you load that driver, the /dev/hda2 will "magically" appear on the client as /dev/etherd/e1.0 - if it is located on the same physical ethernet segment everything you read/write from/to /dev/etherd/e1.0 goes straight ahead to /dev/hda2 If you have further questions - that`s what this list is for.... :) regards roland _______________________________________________________________ SMS schreiben mit WEB.DE FreeMail - einfach, schnell und kostenguenstig.

Hi, thanks. It's nice and work too. But now, it's possible initialize disk AOE from both localhost and external client? This block device must be shared between localhost (vblade server) and a client on lan segment. lo interface is visible only by localhost. Thanks. Francesco |

This is possible by running multiple vblade instances that access the same file or block device. However, if you want to use a standard filesystem, you need to make sure that only one client will have it mounted with write access at any given time. -Hilko |
