Problem Solved

User calypso sekarang memiliki permission yang cukup untuk:

• ✅ Mengakses raw disk devices (/dev/sd*)
• ✅ Menjalankan ZFS commands (zpool, zfs)
• ✅ Membuat dan menghapus ZFS pools
• ✅ Mengakses tape devices
• ✅ Menjalankan SCST commands

Changes Made

1. System Groups ✅

sudo usermod -aG disk,tape calypso

2. Sudoers Configuration ✅

File: /etc/sudoers.d/calypso

• ZFS commands: zpool, zfs
• SCST commands: scstadmin
• Tape utilities: mtx, mt, sg_*
• System monitoring: systemctl, journalctl

3. Backend Code Updates ✅

• Added helper functions: zfsCommand(), zpoolCommand()
• All ZFS/ZPOOL commands now use sudo
• Updated files:
  • backend/internal/storage/zfs.go
  • backend/internal/storage/zfs_pool_monitor.go
  • backend/internal/storage/disk.go
  • backend/internal/scst/service.go (already had sudo)

4. Service Restart ✅
