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?

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 virt_image_t "/vmstore(/.*)?" restorecon -R /vmstore So far I've noticed then when taking snapshots and also...

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).

...ely appear bigger, up to the size of the smallest brick. Now, I had a problem on my setup, long story short, an LVM bug has forcibly unmounted the volumes on which my bricks are running, while gluster was being used. The problem is that instead of having a 8TB file system mounted on /mnt/bricks/vmstore the server suddently found an empty /mnt/bricks/vmstore pointing on / of this server (20GB) After 3 hours during which Gluster complained about missing files on node1 (but continuing to serve files from node2 transparently), it decided to start healing from the correct node to this empty /mnt/...

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: 192.168.50.2:/rhgs/brick1/vmstore Brick3: 192.168.50.3:/rhgs/ssd/vmstore (arbiter) Option...

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

Finally got a new server the other day. You know I had to try out centos 6 with this one. dual quad cores, 24 gb ram (12 for each cpu) 6 working drives bays. My first big surprise was the partition system with anaconda. It is a lot different than the centos 5.x version. I am sure it is a bug that it has options for hot spares but does not allow it to be ungreyed out. I think in the end I will
