High number of XFS extents migrating disk from iscsi to Gluster
Hi!, I've been migrating my Ovirt storage from iscsi to Gluster. What I've been doing is moving the disks with the VM powered off. This procedure was fine until I tried to migrate a 100GB disk from a VM with an Oracle DB. During this migration the access to Gluster slowed down, affecting the whole cluster (VDSM timeout in oVirt Engine, VM's entered in unknown state, gluster client disconnected from a brick) What I found in gluster servers was a XFS error: XFS: possible memory allocation deadlock in kmem_alloc (mode:0x250) And this error is due to the number of extents of the file (~ 8M): gluster01:/gluster/ovirt1_brick_01/brick/89c4e113-1003-4b4e-850e-e7fc5bf2edc6/images/e5b7fc46-4168-4019-a13a-f9b7093d0534#
xfs_bmap f9cd555d-fd98-499f-a853-d0ce76eecd37 | wc -l 8627613
I'm using Gluster 3.6.2 and Centos 7 (3.10.0-229.1.2.el7.x86_64 kernel). Does anyone know why is qemu-img generating this so fragmented file?

Hey I need help, with the installation of oVirt (again). After installing gluster and getting this up and running, I am trying to install ovirt, by first running this command: yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release35.rpm and then yum install -y ovirt-engine However this does not work as I get: Error packages does not exist. Can some please tell me how to fix it? I have tried to run yum update -y, which did not help at all Thanks in advance. - Lars

Sorry, which distribution and which architecture are you trying to deploy on?

We are still not supporting fedora 21 and we will probably jump to fedora 22 skipping 21 at all. Please see: https://bugzilla.redhat.com/show_bug.cgi?id=1163062

No, cause it is using fc$releasever variable in the yum repo specification and it doesn't exist for fc21.
Can some please tell me how to fix it? I have tried to run yum update -y, which did not help at all
Thanks in advance.

Lars, will a developer setup (namely no RPM) is something which can get you started? maybe be worth giving a try if you don't plan to use some supported platform
Can some please tell me how to fix it? I have tried to run yum update -y, which did not help at all
Thanks in advance.
