Host: Central (StorageSample query violated High disk usage) in Domino 3.x

To troubleshoot this problem, ssh to the central server and run the following commands to check the disk usage:

sudo -i
df -h

You will get output similar to this:

Filesystem              Size  Used Avail Use% Mounted on
...
/dev/nvme0n1p1           30G  6.3G   23G  22% /
...
/dev/mapper/vg0-domino  996G  781G  214G  79% /domino
/dev/mapper/vg0-logs    7.8G   49M  7.3G   1% /domino/logs
...

High disk usage is considered to be above 75%.

If you see high disk usage on the filesystem mounted on:

• /domino - follow the rest of this article
• /domino/logs - refer to troubleshooting /domino/logs high disk usage
• anything else - refer to troubleshooting / high disk usage

Now lets diagnose the cause of high disk usage:

du /domino/* --max-depth=1 -kh 2>/dev/null | sort -hr | head

You will get output similar to this:

651G /domino/registry
51G  /domino/logging-elasticsearch
24G  /domino/elasticsearch
15G  /domino/docker
14G  /domino/mongodb
2.7G /domino/backup

If most of disk space is consumed by registry as in the example above, you need to resize the volume. If it is consumed by something else, or if you are not sure how to resize the volume, get in touch with Domino support.
