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)#

Install utilities: apt update && apt install cifs-utils
Create credentials file: /etc/smb-credentials with chmod 600.
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
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).
