Analyzing Log Partition Usage

Scenario

Log rotation has stopped working correctly, and you suspect that /var/log might be mounted on a different filesystem with limited space or incorrect mount options.

Task

Determine which filesystem or device /var/log is mounted on, including device name, mount point, filesystem type, size, and usage. Save the findings to /home/devops/varlog_filesystem_info.txt Optionally identify if this filesystem differs from / which could provide additional info on causes of log rotation or space issues.

Example

# After (filesystem identified and analyzed)

Filesystem      Size  Used Avail Use% Mounted on
/dev/sdb1       10G   9.8G  200M  98% /var/log

Mount details:
/dev/sdb1 on /var/log type ext4 (rw,relatime)
