similar to: Filesystem too large...

We recently added a disk to our Coraid SAN. We''ve used tons of devices off of this SAN with Xen before, but this time we experienced some weird behavior. I configured a DomU to have the device directly offered as a disk (i.e. ''phy/dev/etherd/e1.1,sdb1,rw''). When I tried to boot it, an xvd process showed up as usual. However, it consumed 100% processor

Hi, I'm pretty new to ocfs2 and a bit stuck. I have two Debian/Squeeze (testing) machines accessing an ocfs2 filesystem over aoe. The filesystem sits on an lvm2 volume, but I guess that is irrelevant. Even when mostly idle, everything accessing the cluster sometimes hangs for about 20 seconds. This happens rather frequently, say every 5 minutes, but the interval seems irregular while the

Dear all: I''m sorry I crossmail. I try setup aoe-vblade server on netbsd 5.0.2(domU) and I try to do some stress test with for i in {65536}; do dd if=/dev/zero of=/dev/etherd/e?.? bs=4K;done on a Linux box Two Xen dom0 configurations I use: 1. 32bits SuSE Enterprise Linux 11sp1 2.6.32.12-0.7-xen with 32bits Xen 4.0.0_21091_04-0.2.6 2. 64bits Gentoo 2.6.32-xen-r1 with 64bits Xen 4.0.0

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

I am using R for a graduate class on linear models that I teach. I sent the class a sample transcript of explicit construction of the model matrix and use of the QR decomposition. One of the members of the class picked up on the fact that the model matrix was not what I advertised that it should be when a two-sided formula is used. A one-sided formula works properly. For example, >

If you''re talking about domU, then it''s normal. Whatever the block device is on dom0 (/dev/etherd/*, /dev/mapper/*, etc.) domU sees only /dev/xvda (or whatever you tell it to be).

Hi everyone, This is a strange problem I have been having. I'm not sure where the problem is, so I figured I'd start here. I as having problems with Bacula stopping on 17Gig Volume sizes, so I decided to try to Just dd a 50 gig file. Sure enough, once the file hit 17 gigs dd stopped and spit out an error (pandora bacula)# dd if=/dev/zero of=bigfile bs=1M count=50000 File size

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 have an OCFS2 filesystem on a coraid AOE device. It mounts fine, but with heavy I/O the server self fences claiming a write timeout: (16,2):o2hb_write_timeout:164 ERROR: Heartbeat write timeout to device etherd/e0.1p1 after 12000 milliseconds (16,2):o2hb_stop_all_regions:1789 ERROR: stopping heartbeat on all active regions.

Hi I install CentOS 5.4 and try to use Xen.... But when I deploy some VM with Virt-manager and specify 2 or more VCPUS to use, when start the vm it start with just one CPU... On this VM I install Windows 2003 Server... This the file of VM: name = "Avision" uuid = "625139bf-1ad3-86fc-45e6-e8efbb9db643" maxmem = 2048 memory = 2048 vcpus = 4 cpus = "0,1,2,3" builder =

I understand that all work is going into xen3, but I had wanted to note that aoe (drivers/block/aoe) is giving me trouble on xen 2.0.6 (so we can keep and eye on xen3). Specifically I can''t see nor export AOE devices. As a quick background on AOE, it is not IP (not routable, etc), but works with broadcasts and packets to MAC addresses (see http://www.coraid.com). (for anyone who

I have a Fedora Core server running: Fedora Core release 4 (Stentz) kernel version: 2.6.15-1.1833_FC4smp ( I have also tried kernel version: 2.6.16-1.2108_FC4smp) I compiled the ocfs2 and ocfs2-tools using the following steps: # MODULES: tar zxvpf ocfs2-1.2.1.tar.gz cd ocfs2-1.2.1 ./configure make make install # TOOLS: tar zxf ocfs2-tools-1.2.1.tar.gz cd ocfs2-tools-1.2.1 ./configure

Are we likely to see patches to allow 16TB ext3 in the mainstream kernel any time soon? I am working with a storage box that has 16x750GB drives RAID5-ed together to create a potential 10.5TB of potential storage. But because ext3 is limited to 8TB I am forced to split into 2 smaller ext3 filesystems which is really cumbersome for my app. Any ideas anybody?

Guys, I have setup my hard disc with 3 partitions: 1- 256MB on /boot; 2- 2GB on / for my dom0 (Debian 5.0) (eth0 default bridge for guests LAN); 3- 498GB exported with vblade-persist to my network (eth1 for the AoE protocol).

I am running the Eucalyptus 2.0 cloud computing platform on an up-to-date CentOS 5 using the xen hypervisor. While attempting to attach a volume successfully created using jclouds with eucalyptus to a running VM instance, I encountered the following error: libvirt: Requested operation is not valid: Xm driver only supports modifying persistent config (code=55) i also tried attaching

I am trying to mount the same partition from a KVM ubuntu 8.04.1 virtual machine and on an ubuntu 8.04.1 host server. I am able to mount the partition just on fine on two ubuntu host servers, they both talk to each other. The logs on both servers show the other machine mounting and unmounting the drive. However, when I mount the drive in the KVM VM I get no communication to the host

As part of adding support for OCFS2 to mount huge volumes, we need to check that the sector_t and page cache of the system are capable of addressing the entire volume. An identical check already appears in ext3 and ext4. This patch moves the addressability check into its own function in fs/libfs.c and modifies ext3 and ext4 to invoke it.

I was learning about the different FS exists. I was working on systems that ReiserFS was the star but since there is no longer support from the creator there are other consolidations to be done. I want to ask about couple FS options. EXT4 which is amazing for one node but for more it's another story. I have heard about GFS2 and GlusterFS and read the docs and official materials from RH on

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
