You should mount the Jive system home directory (by default, this is
/usr/local/jive) on redundant external storage (preferably SAN
storage via redundant HBAs and SAN fabric). When redundant external storage is not
available, the local system volume for your Jive installation
directory should be mirrored across multiple physical disks to prevent the loss of a
single disk as a single point of failure.
The total storage requirements for this directory will vary from installation to
installation. As a basic guide for capacity planning, consider the following:
- Core binaries - The base installation requires 500MB storage (200MB on disk,
an additional 300MB needed during upgrades of the platform).
- Total system traffic - The system writes all logs to your
Jive installation directory/var/logs. While the system
will by default rotate log files to reduce disk space consumed, larger installations
may wish to retain log files for analysis over time (HTTPD access logs for example).
In a default installation, allocating 5GB for log storage should provide ample room
to grow.
- Cache efficiency - For each application, local caches of binary content
including attachments and images are maintained. The more space available to
those caches, the more efficient the system will be at serving binary
requests and the smaller the strain on the backing RDBMS. As a capacity
guideline, plan on roughly .25 the planned total binary (BLOB) storage in
the RDBMS for efficient caching.
- Search index size - Each node stores local copies of the system search
index. As a general rule of thumb, plan for search indexes to be 1x the
total database storage consumption (.5 for active indexes, . 5 for index
rebuilds).
- Local database backups - When using the Jive
platform-managed database, the database will regularly be backed up to
your Jive installation directory/
var/data/backup/full and database checkpoint segments backed up to
your Jive installation
directory/var/data/backup/wal. When an instance is using this
database, approximately 35x the total database size will be required in the
your Jive installation directory/var/data/backup location
with a default configuration. This number can be lowered by more aggressively
removing full backup archives stored in backup/full and by more aggressively
removing WAL segments after a full backup has been performed.
