Maintenance¶
Upgrade IRI¶
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.
If using 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.
Note
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/
Note
To check free space on the system’s paritions use df -h
If one of the paritions’ usage exceeds 85% you should consider a cleanup.
Don’t worry about the /boot paritition though.
Check Logs¶
Follow the last 50 lines of the log (iri):
journalctl -n 50 -f -u iri
For iota-pm:
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.
Replace Database¶
If you want to re-download a fully synced database please refer to Where can I get a fully synced database to help kick start my node on how to get this done.
