Requirements

Before getting started, ensure you have:

• Linux kernel 5.8+ with io_uring support
• Rust 1.65+ (minimum supported Rust version)
• 512 KiB locked memory for io_uring

Adjusting memlock limit

Glommio requires at least 512 KiB of locked memory for io_uring. Increase the memlock resource limit:

# Edit limits.conf
sudo vi /etc/security/limits.conf

# Add these lines:
*    hard    memlock        512
*    soft    memlock        512

Log out and back in for changes to take effect. Verify with:

ulimit -l
# Should output: 512
