描述

Right now we supports XFS/RAID volume construction on scylla_setup, but it always specifies /var/lib/scylla for data/commitlog directories. But user may have existing XFS volume on custom directory on /xfs or somewhere, not on our dir. Maybe we should have following prompt on scylla_setup interactive mode:

Do you want to setup Scylla data directories? [Y/n]

Input Scylla data directory: [default: /var/lib/scylla/data]

Input Scylla commitlog directory: [default: /var/lib/scylla/commitlog]

Do you want to setup RAID and XFS for data directories? [Y/n]

研究方向
The issue suggests enhancing the scylla setup script to prompt for custom data and commitlog directories. Look for the script file in the repository (likely under `tools/scylla setup` or similar). The current implementation hardcodes paths; you would need to add interactive prompts with defaults, and optionally validate the provided paths. Check existing code for RAID/XFS setup to understand the flow. The single comment may contain additional context.
