Select the “Create LVM volume group” button to open the creation dialog. Once a volume group has been created, it

node in the figure represents a data node (ChunkServer). A CopySet is the basic unit of data replication in CurveBS. A CopySet contains multiple chunks. Copysets in CurveBS are created in advance. 1. Reduce metadata. If the replication group membership is saved for each chunk, the number of metadata will be large. 2. Example Reduce the number of replication groups. The size of chunk is such as 16MB by default. If replication groups are created based on chunk. The number of replication groups is large and the communication traffic between replication groups is heavy. Once a CopySet

(PV): physical hard disk, disk partition or software RAID partition formatted as LVM PV. • Volume Group (VG): is made from one or more physical volumes. A VG can can be extended by adding more PVs. A VG a LVM volume. During the initial install only one Physical Volume (PV) will be part of the Volume Group (VG). Another PV will be added after install to demonstrate how a VG can be extended. There are several changes to disk. 7. For the "LVM configuration action" on the next screen, choose "Create volume group". Enter a name for the VG such as vg01, or something more descriptive. After entering a name, select

addition to automatic user creation and updating the new functionality also allows to specify user group and user media matching between LDAP/SAML and Zabbix. Provisioned users will be marked in the user device, application, service, or any other logically-related collection of monitored parameters. host group - a logical grouping of hosts. Host groups are used when assigning access rights to hosts for different apply mass changes to monitoring tasks. Templates are linked directly to individual hosts. template group - a logical grouping of templates. Template groups are used when assigning access rights to templates

checking non-privileged user per- missions. These tables keep hashes (SHA-256) of user group sets and host group sets for each user/host respectively. Additionally, there is a permission table storing groups previously discovered and created by other low-level discovery rules based on the specified group prototypes. Templates Frontend US time format Time and date displays in the frontend now conform intended for configuring and mass updating of the map elements and shapes; • Configuration of user group permissions and tags for filtering viewable problems has been refined. Now it is possible to select

consistent Zabbix feature in previous versions was the presence of many dropdowns for host and host group selection, and sometimes also for selecting other elements like graphs. Typical locations for these into filters Note that: • two host group and host dropdowns are in places changed to a single host multi-select field followed by a Select popup for host group selection • there is also a new option trigger/data overview pages and widgets Please see individual pages for details on changed host/host group/graph/etc selection: • Monitoring: – Dashboard (host selection with dynamic widgets) – Host graphs

in Zabbix, it becomes possible to select the required LDAP server for the respective user group, in user group configuration. Storage of secrets It is now possible to store some sensitive information A new subsection Template groups has been added to the Configuration menu. User role and user group permissions are now defined separately for host groups and template groups. AWS EC2 monitoring A fail on a UUID mismatch of an importable entity (host group, item, graph, etc). For example, it was not possible to import a host group if a host group with the same name already existed on the host. In

respective forms. In a related development, in host prototype configuration the fields for host group/host group prototype selection have also been moved from a separate tab to the first tab. Subfilter in entity group (e.g. tags, hosts) up to 10 rows of entities are now displayed. If there are more entities, this list can be expanded to a maximum of 1000 entries (the value of SUBFILTER_VALUES_PER_GROUP in to 10 rows of values are displayed (expandable to 1000 entries (the value of SUBFILTER_VALUES_PER_GROUP in frontend definitions)).
