Next on the list which 675 R has is adjustable OHLINS suspension - apart from adjusting the front and rear pre-load (which you normally don't change) , we can play around with compression and rebound settings - depending on the the kind of road you are riding on (bumpy or has pot holes or smooth etc) - or if it's a race track. 3 1 Introduction OpenStack continues to gain significant traction in the industry because of the growing adoption of cloud usage and the flexibility OpenStack offers as an open source product This document describes the reference Managing Ceph pools . If you're looking to deploy a local Amazon Simple For the very latest ZFS binaries, you will need to use Solaris as the ZFS on Linux project is slightly behind the main release. z and will be used by default when provisioning new OSDs with ceph-disk, ceph-deploy, and/or ceph-ansible. The major difference between previous versions, apart from the lower case names, are the renaming of some prefixes, like celerybeat_ to beat_, celeryd_ to worker_, and most of the top level celery_ settings have been moved into a new task_ prefix. Cannot create a cloud storage disk pool . About Ceph Enterprise-class cloud storage Ceph delivers object, block and file storage on one platform, delivering: Scalability from petabytes to exabytes High Availability--hardware failure is an expectation, not just an exception The topology of a Ceph cluster is designed around replication and information distribution, which are intrinsic and provide data integrity. 2. Unlike FileStore, which writes all data to its journal device, BlueStore only journals metadata and (in some cases) small writes, reducing the size and throughput requirements for its journal. 0 introduced new lower case settings and setting organization. One major feature that distinguishes ZFS from other file systems is that ZFS is designed with a focus on data integrity. (integer value) #backup_ceph_chunk_size=134217728 # The Ceph pool where volume backups are stored. If you set pool size more than 3 (and increase the max_size in crush), be careful : you will have n-1 replica on one side and only one on the other datacenter. The Ceph OSD dashboard provides information for a specific OSD in the cluster. mBlueStore is a new storage backend for Ceph. In the case of edge and re Create the Hue database and grant privileges to a hue user to manage the database. In compressed extents, individual blocks are not compressed separately; rather, the compression stream spans the entire extent. root # ceph osd pool set POOL_NAME ompression_algorithm snappy root # ceph osd Replace POOL_NAME with the pool for which to enable compression. For replicated pools, it is the desired number of copies/replicas of an object. For years, they got additional business because the process was to email or call & wait 10 minutes for a detailed quote which was correct on the first try. 5 Data Compression 133 Enable Compression 133 • Pool Compression Options 134 • Global Compression Options 135 8 RADOS Block Device137 8.
