Last update: 26-11-2022

Symptoms

Cluster update eligibility check shows the following message:

"Not enough space on / or /boot on these nodes: < affected node name >"

Example:

Cause

It is caused by to lack of space in root partition ( / ) or in boot partition ( /boot ) on system disk. 

Be aware about General Requirements regarding the required disk size for "System" disk.

Solution

1. Check partitions utilization on the issued node using the df command, example output of case with full /boot partition:

[root@acinode1]# df -h / /boot
Filesystem               Size  Used Avail Use% Mounted on
/dev/mapper/centos-root   50G  7.9G   43G  16% /
/dev/sda1               1014M  1014M  0M  100% /boot

2. In case of the lacking space on the root partition, try to reduce the log rotation per 69964: Acronis Cyber Infrastructure: How to set up custom log rotation.

3. In case of the lacking space on the boot partition ( /boot ), run below command in the affected node to clean-up old and no longer needed kernel packages:

# package-cleanup --oldkernels --count=2
