Hi, I'm running into problems with blockcommit and gluster network disks - wanted to check how to pass path for network disks. How's the protocol and host parameters specified? For a backing volume chain as below, executing virsh blockcommit fioo5 vmstore/912d9062-3881-479b-a6e5-7b074a252cb6/images/27b0cbcb-4dfd-4eeb-8ab0-8fda54a6d8a4/027a3b37-77d4-4fa9-8173-b1fedba1176c --base

Hi everyone. I'm running a simple Gluster setup like this: ? * Replicate 2x1 ? * Only 2 nodes, with one brick each ? * Nodes are CentOS 7.0, uising GlusterFS 3.5.3 (yes, I know it's old, I just can't upgrade right now) No sharding or anything "fancy". This Gluster volume is used to host VM images, and are used by both nodes (which are gluster server and clients).

I recently began getting periodic emails from SEalert that SELinux is preventing /usr/libexec/qemu-kvm "getattr" access from the directory I store all my virtual machines for KVM. All VMs are stored under /vmstore , which is it's own mount point, and every file and folder under /vmstore currently has the correct context that was set by doing the following: semanage fcontext -a -t

Splitting the list or goofy offers to do the list as a PHPbb, NNTP, or other forums would only serve to dilute the value of the collective wisdom of the people on this list. Suppose the

So, after playing with 6.0 on the Cisco 7960 and 7940 platforms, I have the following gripes, which I've sent to a very clueful Cisco person already. Mind you, I love the Cisco 79xx series phones, and currently they are what I recommend to anyone who wants a 'real' IP phone. I just cringe - Speed dials. It's nice to now have speed dials in the line appearances that

I have been a member of the mailing list for a couple months now. I have not contributed anything because it has been difficult to gain a toehold from which I could really understand the concepts used in Ogg Vorbis. I would like to help out, but it is hard to get an idea of the overall architecture with docs like http://www.xiph.org/ogg/vorbis/doc/vorbis.html , in which every link is dead.

Hi, I have a gluster 3.10 volume with a dir with ~1 million small files in them, say mounted at /mnt/dir with FUSE, and I'm observing something weird: When I list and stat them all using rsync, then the lstat() calls that rsync does are incredibly fast (23 microseconds per call on average, definitely faster than a network roundtrip between my 3-machine bricks connected via Ethernet). But

I did a quick test on one of my lab clusters with no tuning except for quota being enabled: [root at dell-per730-03 ~]# gluster v info Volume Name: vmstore Type: Replicate Volume ID: 0d2e4c49-334b-47c9-8e72-86a4c040a7bd Status: Started Snapshot Count: 0 Number of Bricks: 1 x (2 + 1) = 3 Transport-type: tcp Bricks: Brick1: 192.168.50.1:/rhgs/brick1/vmstore Brick2:

I've created a very basic snapshot XML file, to allow for a description of the snapshot. However when running the virsh command, it doesn't like the formatting. # virsh snapshot-create proxy_0 /vmstore/proxy_0/proxy_0_ss.xml error: XML description for failed to parse snapshot xml document is not well formed or invalid This are the XML file contents... # cat proxy_0_ss.xml

Hello guys, I am using PAM (0.82) to authenticate (samba) workgroup users and it works fine (pam_smbpass). But after joining a domain and start using pam_winbind too, pwauth (2.3.10) get a segmentation fault when trying to authenticate any workgroup or domain user. What happens is that it does authenticate the user successfully, but when it calls pam_end() to release its resources, it crashes.

(note: i asked this a few days ago but it *appears* that that post was tossed due to getting excessive bounces from my account. so i'm posting it again, apologies if you're seeing it a second time.) over the next several weeks, i'm teaching some courses in RHEL admin but (unsurprisingly) i'll be using centos 5.5. it's a decently-written, 3rd party course, all the generic,

Ling, I got the Agile Development with RoR book. As my next project was to be a bespoke online shop, I started by trying to copy the complete tutorial project - an online shop. I got a load of errors and had no way of working out how to fix them... Or extend the code and write new rails projects. When I took out a couple of days to go through the tutorial step by step, I ended up with a

Hi, I have an 2 nodes with 20 bricks in total (10+10). First test: 2 Nodes with Distributed - Striped - Replicated (2 x 2) 10GbE Speed between nodes "dd" performance: 400mb/s and higher Downloading a large file from internet and directly to the gluster: 250-300mb/s Now same test without Stripe but with sharding. This results are same when I set shard size 4MB or

Hi all. I've been playing around with KVM for a bit now and have several virtual machines up and running. Having passed what I considered "first look" stage, I'm ready to start using libvirt as a manager. For reference, pre-libvirt, I have started this VM with: /kvm -net nic,model=virtio -net tap,ifname=tap5,script=no -drive file=test1.img,if=virtio,boot=on -curses
