How do I diagnose what's going wrong with a Gluster NFS mount?
Hi, Has anyone even seen this before - an NFS mount through Gluster that gets the filesystem size wrong and is otherwise garbled and dangerous? Is there a way within Gluster to fix it, or is the lesson that Gluster's NFS sometimes can't be relied on? What have the experiences been running an external NFS daemon with Gluster? Is that fairly straightforward? Might like to get the

Odd failure of smbd to start from init.d - CentOS 5.4
Hi, We've got a fresh CentOS 5.4 box, and the only glitch so far is that /etc/init.d/smb doesn't start smbd. It claims it does - shows "[ok]" - but only nmbd ends up running. Even setting a higher debugging level in the smbd flags, nothing logs or shows on the console as to why smbd is immediatly quitting. To make it stranger, doing this works fine: . /etc/init.d/functions

RTNETLINK answers: File exists
Can someone tell me what concept I''m missing here. The setup is simple. I have two default routes after ifup operations. I use "ip route del" to remove one, but then decide to add it back. The attempt is refused. Why? # ip route ls 66.95.83.208/28 dev eth1 proto kernel scope link src 66.95.83.210 65.84.205.96/27 dev eth2 proto kernel scope link src 65.84.205.104

ESXi & Gluster setup options
All, We are in the process of determining a virtualized infrastructure and wanted to hear from current users of Gluster and VMWare. What we were looking to setup was an HA ESXi cluster (2 heads) with gluster backend (4 bricks to start, replicated/distributed), all backend connectivity would be 10Gbe. Mainly the storage would be for VM images but may include NAS files later. So our

Can Samba lock files until copy is complete?
Hi, We've got a system where staff use Samba mounts on their Windows desktops to drop files into a Linux directory for further processing. Some of those files are large, and take time for the file copy across Samba to complete. The problem is that looking at the directory from the Linux side, to see if there are new files to process, the directory listing for the files-copied-across-by-Samba

How can a bridge be optimized?
Hi, Netperf tells me that a KVM VM using a bridged connection to a system across the Gigabit LAN sees on average about 1/10th of the bandwidth the host sees. This is on very lightly loaded hosts, although with multiple low-use VMs. I've tried adjusting the CPU throttling after seeing that mentioned as a possible factor in slowing down a bridge, but it has not much if any effect here. Is

Libvirt Seg Fault when compiling either 0.9.13 or 0.10.0-rc1
Hi all, I am trying to install a version of Libvirt that will be compatible with qemu-kvm-1.1 but I cannot seem to get Libvirt to compile.

Striped replicated volumes in Gluster 3.3.0
Hi all, I'm very happy to see the release of 3.3.0. One of the features I was waiting for are striped replicated volumes. We plan to store KVM images (from a OpenStack installation) on it. I read through the docs and found the following phrase: "In this release, configuration of this volume type is supported only for Map Reduce workloads." What does that mean exactly? Hopefully not,

Finding cause when "virsh list" hangs
Hi, Did something dumb - had two VM hosts with DRBD mirroring of VMs on the same UPS, which failed and crashed them both. While I've got VMs running now on both, "virsh list" and "virsh start" and so on are just hanging. I'm not seeing it log anything in these instances - just hanging. Both systems are Ubuntu 10.10, one with the stock libvirtd 0.8.3 and one with

PHP file upload limit
Hi all, I am trying to run a web-based PHP application on a CentOS 5 32-bit machine that requires me to upload large files. The machine also happens to have little RAM (256MB). I have no problem setting my upload limit ( upload_max_filesize ) to 1 GB but for some reason 2 GB or above seems to be no go. Would anybody know why? Could it be one of the many 32-bit vs 64-bit issues? Thanks. Boris.

Load Balance RX/TX data on the same NICs.
Hello, I have a Compaq Proliant i850R, running RedHat 7.1. There are 3 NICs attached to it, 2 eepro100, and 1 ThunderLAN driver v1.14a. This box is being prepped to be a download server. GOAL: Requests are sent to each NIC via seperate IP addresses. All 3 are on the same subnet. All requests are load balanced via a DNS server. We want all requests to exit the same NIC that they entered. PROBLEM:

single storage server
I have a single storage server which exports /data to number of clients. Is it ok to access the data on the storage server directly (ie not via glusterfs mount) ? (I know this causes problems when there are multiple servers ). This would simplify some configurations. Nick

Wanted: method for qemu hook script to know if called for migration
Hi, "Before a QEMU guest is started, the qemu hook script is called" (http://libvirt.org/hooks.html)... In writing a simple bash script to prevent a VM on shared storage from being started on one host if it's already running on another, it's easy enough to check if virsh on the other host reports the particular VM as "shut off" there, and go ahead if that's the

smbd start trouble - CentOS 5.4
Hi, I've been through a long discussion of this on the CentOS list, where people are quite helpful, yet we've gotten nowhere with it. With smbd Version 3.0.33-3.14.el5 on two different CentOS 5.4 64-bit boxes, "/etc/init.d/smb start" reports OK for both nmbd and smbd, but an instant later smbd stops running, with no errors reported - just fails, no matter what logging level is

winbind - not ready for prime time?
What's the consensus? Should winbind even be considered for production use? Looking back through the archives of the Samba lists, there's a lot of doubt about it. Where people have had problems, there are more often than not no solutions given. When I look at the man page in 3.0.28, there are litterally blank spots awaiting completion, and lack of documentation of sometimes-essential
