ENOSPC

No space left on device

Solutions

Prerequisites: Start by updating your system to resolve common issues and ensure the solutions provided below are compatible with your current environment.

check_latest_version && sudo apt update && sudo apt upgrade -y

Check disk usage

Identify space usage:

df -h

du -sh /*

du -sh /path/* | sort -hr

Free up space

Remove unnecessary files:

sudo apt autoremove

sudo journalctl --vacuum-time=7d

find /tmp -type f -atime +7 -delete

Check inodes

Verify inode usage:

df -i

find /path -type f | wc -l

for dir in /*; do echo "$dir: $(find "$dir" -type f | wc -l)"; done

What is ENOSPC?

ENOSPC occurs when there is insufficient space on the storage device to complete an operation.

Common scenarios: Disk full, inode exhaustion, or writing to filesystems at capacity.

Common Causes

Disk space completely used
Inode table full
Large log files
Temporary files accumulation
Snapshot or backup files

Debugging Tips

lsof | grep deleted

du -x --max-depth=1 /

find / -size +100M -type f

stat -f /path

Prevention

Monitor disk usage regularly
Set up log rotation
Clean temporary files periodically
Use disk quotas
