Latest IRI release is available here.
If a new version has been announced, you can follow this guide to get the new version or use the menu-driven tool
iric to get the latest IRI version.
iric, make sure to update it to the latest version before using it to upgrade IRI.
In the following example we assume that the new version is 1.6.0.
The foundation might announce additional information in tandem with upgrades, for example whether to use the
--rescan flag, remove older database etc.
If required, additional options can be specified under the
OPTIONS="" value in the configuration file (
/etc/default/iri for Ubuntu or
/etc/sysconfig/iri for CentOS). The database folder is in
/var/lib/iri/target/mainnetdb and can be removed using
systemctl stop iri && rm -rf /var/lib/iri/target/mainnet*.
You can update IRI using the
iric tool: Fullnode IRI Configuration Utility. Make sure that there are no additional manual steps to be taken if any are announced by the Foundation.
Upgrade IOTA Monitoring¶
IOTA Prometheus Monitoring is used by Grafana which are the awesome graphs about the full node.
You can update the monitoring using the
iric tool: Fullnode IRI Configuration Utility.
Check Database Size¶
You can check the size of the database using
du -hs /var/lib/iri/target/mainnetdb/, e.g.:
# du -hs /var/lib/iri/target/mainnetdb/ 4.9G /var/lib/iri/target/mainnetdb/
To check free space on the system’s paritions use
If one of the paritions’ usage exceeds 85% you should consider a cleanup.
Don’t worry about the /boot paritition though.
Follow the last 50 lines of the log (iri):
journalctl -n 50 -f -u iri
journalctl -n 50 -f -u iota-pm
Click ‘Ctrl-C’ to stop following and return to the prompt.
Alternatively, omit the
-f and use
--no-pager to view the logs.
