What causes Linux inode exhaustion ?

Rogue apps creating millions of small (often empty) files, like debug logs or tempfiles, without cleanup. Disk space stays free, inodes vanish.

How do I check inode usage on Linux?

Run df -i. Look for 90%+ IUse%. Then find /path -type f | wc -l to count files.

Can inode exhaustion happen in the cloud?

Absolutely—EBS, GCP disks inherit fs limits. Happens daily in over-logged clusters.
