It is important to monitor the disk usage of Tanzu GemFire members. If a member lacks sufficient disk space for a disk store, the member attempts to shut down the disk store and its associated cache, and logs an error message. A shutdown due to a member running out of disk space can cause loss of data, data file corruption, log file corruption and other error conditions that can negatively impact your applications.
After you make sufficient disk space available to the member, you can restart the member.
You can prevent disk file errors using the following techniques:
When a disk write fails due to disk full conditions, the member is shutdown and removed from the cluster.
If a member of your cluster fails due to a disk full error condition, add or make additional disk capacity available and attempt to restart the member normally. If the member does not restart and there is a redundant copy of its regions in a disk store on another member, you can restore the member using the following steps:
show missing-disk-storescommand to identify any missing data. You may need to manually restore this data.
