Hello, I have encountered a crash in dom0 kernel while booting a domU from an AOE device. I haven''t seen such crashes when booting from local partitions/ LVM volumes/ loopback file systems. Also I haven''t seen such crash when I did repetitive I/O to these AOE devices. As the call trace of crash indicates the crash is in xenolinux kernel. Also this crash is predictably

I''ve been brainstorming... I want to create a 2-node HA active/active cluster (In other words I want to run a handful of DomUs on one node and a handful on another). In the event of a failure I want all DomUs to fail over to the other node and start working immediately. I want absolutely no single-points-of-failure. I want to do it with free software and no special hardware. I want

Hello, I''m trying to setup stateless dom0 host image. The idea is to make dom0 host diskless booted off storage/pxe. What are the best practices of making such a setup ? I already tried nfs-root iscsi-root and aoe-root all these setups works perfect, what about making xen running rootless I mean in ramdisk ? _______________________________________________ Xen-users mailing list

Hello friends, I've got a strange problem with my cluster-setup. I've got two nodes called www1 and www2 running Ubuntu Linux 8.10. The have a 50G volume which is replicated in primary/primary mode with DRBD. On this volume there is an OCSF2 filesystem with this two nodes. Everything is working really fine, files are perfectly mirrored, really nice. On one of the

Hi, We have two nodes with centos 5.5 x64 and cluster+gfs offering samba and NFS services. Recently one node displayed the following messages in log files: Sep 13 08:19:07 NODE1 gfs_controld[3101]: cpg_mcast_joined error 2 handle 2846d7ad00000000 MSG_PLOCK Sep 13 08:19:07 NODE1 gfs_controld[3101]: send plock message error -1 Sep 13 08:19:11 NODE1 gfs_controld[3101]: cpg_mcast_joined error 2

Lustre 1.2.2 has been released! Lustre 1.2.2 contains a significant number of fixes over Lustre 1.2.1 and is a recommended update for anyone running earlier Lustre versions. The most user-visible among them are: - Allow users to set per-directory default striping values - Fix data coherency bugs with concurrent write/truncate - The blocks count is updated on clients for stat without revoking

Hi, I'm not sure if this is apprriate or not, but here goes anyway. The patch below updates MAINTAIER address Individuals (Only Andrew :): osdl.org -> linux-foundation.org Lists: osdl.org -> lists.osdl.org I assume the latter will change at some stage, but at least with this change the osdl/linux-foundation lists are consistent.

Greetings, Xen developers! I have been using AoE with Xen to great effect and I am very pleased with how the whole system has worked out. The two technologies really complement each other. I consider it the ultimate setup. Aside from the network switch (eventually to be remedied) my serving infrastructure has zero single points of failure. However, this virtualization paradise has a flaw:

Hi We use AoE disks for some of our systems. Currently, a 15.65Tb filesystem we have is full, I then extended the LVM by a further 4Tb but resize4fs could not handle a filesystem over 16Tb (CentOS 5.5). I then reduced the lvm by the same amount, and attempted to create a new LV, but get this error message in the process lvcreate -v -ndata2 -L2T -t aoe Test mode: Metadata will NOT be updated.

hi to the list, Hello everyone, I am new in the world of pxe booting and i try to use AOE to boot my linux debian lenny machines. I install the linux like this: parted -s /dev/etherd/e10.1 mklabel gpt parted -s /dev/etherd/e10.1 mklabel gpt parted -s /dev/etherd/e10.1 mkpart primary ext3 17408B 314590207B parted -s /dev/etherd/e10.1 mkpart primary ext3 314590208B 3535815679B parted -s

Hi all, Well I''ve managed to waste a day on this. Posted a similar message earlier today on the fedora list and got no nibbles. I read every article in the archives regarding pxebooting; there is no mention of it in the wiki. I have a box with two kernels, a standard fedora 6 and a xen fedora 6. Both boot fine. I''ve setup another server with dhcp and tftpboot and can now

Hi, I have a working PXE environment that chainloads gPXE and loads pxelinux.0 afterwards. As I'm also interested in doing san boot (in my case aoe) I tried loading the new gpxelinux.0 file instead of my gPXE --> pxelinux.0 setup (works) and booting from my aoe target by adding this to the default config file: LABEL doaoe MENU LABEL Continue AoE kernel sanboot.c32 append

hello ! i try to use a network technology on one single host, which wasn`t designed for that. to give a short overview of what i`m talking about: AoE is just like a "networked blockdevice" (just like nbd/enbd) - but without tcp/ip. AoE kernel driver is the "client end" (see this like an iSCSI initiator) - and an etherblade storage appliance is the "server end"

I've programmed a quick-and-dirty version of symlinks for smbfs. This hack uses the system attribute and otherwise works much like the ncpfs-hack, that is to say, I write the magic cookie at the beginning of the file. Of course the server has to map the system attribute, which samba notably doesn't do by default. smb.conf entries of "map system = yes" and "create mask =

Dear developer, I am working on a project for my graduate work (diploma), which includes iSCSI and AOE booting. I made some menus using pxelinux and things are working fine with linux, but I have a small problem with windows system which require direct iscsi or aoe access. I have dhcpd.conf setup that it to each first dhcp request handles out pxelinux.0, then I can chooose from that menu which OS

Hello everybody, I am in the process of setting up a really cool xen serverfarm. Backend storage will be an LVMed AoE-device on top of DRBD. The goal is to have the backend storage completely redundant. Picture: |RAID| |RAID| |DRBD1| <----> |DRBD2| \ / |VMAC| | AoE | |global LVM VG| / | \ |Dom0a| |Dom0b| |Dom0c| | |

It is documented that KOBJ_ADD should be generated after the object's attributes and children are ready. We can achieve this with the new disk_gen_uevents interface.
