Proxmox Storage Management#

What Was Established#

  • SMB/CIFS shares can be integrated into Proxmox via CLI or the Web GUI.
  • GUI integration is recommended for Proxmox-native features (backups, ISOs, templates) and automatic retention management.
  • Local disk inspection (e.g., sda2) requires verifying mount status and filesystem type to avoid conflicts with active root partitions.

CLI Mounting (Persistent)#

  1. Install utilities: apt update && apt install cifs-utils
  2. Create credentials file: /etc/smb-credentials with chmod 600.
  3. Add to /etc/fstab: //server/share /mnt/smb-share cifs credentials=/etc/smb-credentials,uid=0,gid=0,file_mode=0660,dir_mode=0770,iocharset=utf8 0 0
  4. Test mount: mount -a

GUI Mounting (Proxmox Native)#

  • Navigate to Datacenter → Storage → Add → SMB/CIFS.
  • Required Fields: ID, Server, Share, Username, Password.
  • Content Types (select based on use case):
    • ISO images
    • Container templates
    • VZDump backup files
  • Advanced Options: Max Backups, Prune Backups, SMB Version (e.g., 3.0), Domain.
  • Verification: Green checkmark in Storage list indicates active status. Use “Test Connection” if available.

Local Disk Inspection#

  • Check status: lsblk, blkid /dev/sda2, mount | grep sda2.
  • Mount temporarily: mount /dev/sda2 /mnt/sda2.
  • Inspect: ls -la /mnt/sda2, df -h, du -sh /mnt/sda2/*.
  • Note: sda2 is typically the root partition on Proxmox hosts; avoid modifying if already mounted at /.

Open Questions#

  • Specific purpose of sda2 on Isengard (192.168.1.69)? (Likely root, but verify with lsblk/blkid).
  • SMB share usage for LonelyMountain (192.168.1.137) backups vs ISOs? (GUI method preferred for VZDump retention).
