Machine Room operation error caused the rack or host power down is the occasional thing, then how in this case, let the Ceph service with the OS startup and fast start? Here is a simple method:Execute the following command on the OSD host:sudo ln-s/usr/lib/systemd/system/[email protected]/etc/systemd/system/multi-user.target.wants/[email protected]sudo systemctl enable [email protected]sudo systemctl is-enabled [email protected]Execute the following c

Because the kubelet itself does not support RBD commands, a kube system plugin is required:Download Plugin Quay.io/external_storage/rbd-provisioner：Https://quay.io/repository/external_storage/rbd-provisioner?tag=latesttab=tagsDownload Docker pull quay.io/external_storage/rbd-provisioner:latest on node of k8s clusterInstall only the plugin itself will error: need to install kube roles and permissions The following are:Https://github.com/kubernetes-incubator/external-storageHttps://github.com/kube

Using the Ceph OSD Tree command to view the Ceph cluster, you will find weight and reweight two values Weight weight and disk capacity, general 1T, value is 1.000, 500G is 0.5 It is related to the capacity of the disk and does not change due to reduced disk available space It can be set with the following command Ceph OSD Crush Reweight The reweight is a v

Original link: http://www.cnblogs.com/CloudMan6/p/6397360.html The instance of OpenStack is deployed through glance mirroring, so preparing mirroring is a must. This section describes how to make a Linux image, followed by a discussion of Windows mirroring. Download Clould Mirrors The easiest way to do this is to use standard mirrors. Mainstream Linux distributions provide cloud mirrors that can be used directly in

This is the 2nd chapter in the OpenStack implementation experience sharing series.OpenStack deploys instance through Glance mirroring, the previous section introduces the Linux image authoring method, Windows mirroring is very different from Linux, and today we take windows2008 as an example to discuss it in detail.The image production steps are as follows:1. Create and run the windows2008 KVM virtual machine2. Installing the Virtio Drive3. Installing

[Ceph_deploy] [ERROR] Runtimeerror:failed to execute Command:ceph-disk-activate–mark-init sysvinit–mount/dev/sdb1To be honest, the question is two.I put the OSD in a separate partition SDB executes the commands that are:Ceph-deploy OSD Prepare NETWORK:/DEV/SDB1Ceph-deploy OSD Activate NETWORK:/DEV/SDB1The above is wrong.The right thing isCeph-deploy Osd–zap-disk Create Network:sdbCeph-deploy OSD Prepare NETWORK:/DEV/SDB1:/DEV/SDB2Ceph-deploy OSD Activate NETWORK:/DEV/SDB1:/DEV/SDB2The problem is

Have you modified/sys/block/sdk/queue/read_ahead_kb read_ahead?Modified to 8192, the default value is 128;is the SATA disk OSD changed to 8192? How much of a performance boost?In addition, this value should be modified at any time, right? Can it be dynamically adjusted after deployment?What effect will it have on the OSD?can improve read performanceCan be modified in real timeWhat does this parameter mean?Pre-read bytes?This parameter is useful for sequential reads, meaning how much content to r

Because the yum source download on the openstack official website is slow, we now download the built-in installation packages of openstack, epel, CEpH, and RedHat, and create a local update and install Yum source. 1. Download the package that comes with openstack, epel, CEpH
