Changed

• Dashboard Layout - Removed SystemStatus component in favor of inline I/O gauges
  • SystemStatus and DashboardStats were redundant (both showing CPU/memory)
  • I/O gauges provide unique value not shown elsewhere on dashboard
• Storage Page Buttons - "Create RAID Array" and "Create Storage Pool" now link to dedicated workflow pages instead of opening modals
• NFS/Samba Share Creation - Simplified to only show Storage Pools in path selection
  • Removed LVM Logical Volumes dropdown section to eliminate confusion
  • Storage Pools are now the single source of truth for shareable storage
  • LVM volumes must be mounted as pools first before they can be shared
• Pool Type Validation - Pool creation uses lvm type (instead of lvm_lv) for LVM logical volume pools to match backend expectations

  • Now properly strips "B" suffix before parsing, same as GetVolumeGroups() function
• LVM Pool Name Expression Error - Fixed "pool is not defined" error in LVM page
  • Changed {pool-name || newLV.name} to {newLV.poolName || newLV.name}
  • The hyphenated name was being interpreted as subtraction (pool minus name) instead of a variable reference
• LVM Input Pattern Regex Error - Fixed "character class escape cannot be used in class range" validation error
  • Changed pattern="[a-z0-9-]+" to pattern="[a-z0-9\-]+" to properly escape hyphen in regex character class
  • Allows hyphens in VG and LV names (e.g., "vg-data", "lv-bank")
• Storage Page Tab Structure - Fixed improper if/else block nesting that caused "attempted to close an element that was not open" error
  • Added missing {/if} to close the outer activeTab if/else chain
  • Properly closes tab content div structure

Full Changelog: v1.0.5...v1.0.6

v1.0.5

Added

• ACL UI Improvements - Enhanced ACL interface with detailed LUN display and unmap functionality:
  • LUN Details Display - Each mapped LUN now shows LUN number, name, and size instead of just vague numbers
  • Unmap Buttons - Each mapped LUN has an X button (visible on hover) to unmap it from the client
  • Better Organization - Each ACL is in its own card with clear header showing client name and mapped LUN count
  • Empty State - Shows "No LUNs mapped to this client" when appropriate
  • Missing LUN Detection - Shows "(LUN not found)" for mappings to deleted LUNs
• LUN Number Parsing - Fixed regex-based LUN number extraction in both getNextAvailableLUN() and parseLUNsFromTargetcli() to correctly display LUN numbers (0, 1, 2, etc.)
• RAID Array Deletion - Fixed deletion bug by using device path (/dev/md0) instead of mdadm name (arcanas:1)
• RAID Array Unmounting - Arrays are now unmounted before deletion to prevent "Immutable" errors
• Volume Group Stats - Fixed VG used/available space showing 0 by using --units b for raw byte values instead of human-readable format
• RAID Persistent Naming - Added mdadm.conf management with --homehost to prevent md127 rename on reboot
• Storage Pool Creation - Fixed device filtering to exclude already-mounted devices
• MD Device Visibility - Legacy MD device mounts now appear in storage pools API for NFS/Samba sharing
• NFS Path Update Logic - Export path changes now properly handle delete+recreate workflow
• iSCSI Backing Stores UI - Enhanced to show device availability status with mount point reasons
• Samba Share Permissions for /mnt Mounts - Fixed permission issues for Samba shares on mounts under /mnt by setting proper ownership and permissions on intermediate mount points
• MD Device Samba Permissions - MD RAID devices mounted anywhere are now automatically detected and given proper permissions for Samba access (nobody:nogroup ownership, 0777 permissions)
• iSCSI Target Creation - Fixed bug where created targets had no backing store or LUN attached
• iSCSI Target Update - Targets can now be updated with new backing stores (replaces existing LUN)
• iSCSI targetcli Commands - Fixed all targetcli command paths from relative (iscsi/) to absolute (/iscsi/) syntax
• iSCSI LUN Parsing - Improved LUN detection and backstore path parsing from targetcli output
• iSCSI ACL LUN Mapping - Fixed LUN to ACL mapping by dynamically querying backstore path instead of hardcoding /backstores/block/
• ACL IQN Validation - Fixed IQN input regex pattern to properly validate IQN format with hyphens and colons

Fixed

• iSCSI Slow Link Transfer Behavior - Configured iSCSI target with conservative burst lengths (FirstBurstLength=32KB, MaxBurstLength=64KB) to prevent false transfer completion reporting on slow links (50Mbps/5MB/s). The default 256KB MaxBurstLength caused transfers to appear complete instantly while data continued transferring at line speed in the background.
  • Backend: EnsureISCSITargetConfigured() now sets burst lengths via configfs when creating iSCSI targets
  • Fresh Installs: install.sh creates arcanas-iscsi-config.service to apply settings on boot
  • Upgrades: Run /usr/local/bin/arcanas-iscsi-config.sh manually or restart the service to apply to existing installations
• iSCSI LUN Cache Mode - Configured block backstores to disable thin provisioning unmap emulation (emulate_tpu=0) for more predictable I/O behavior.
• Deploy Script Frontend Sync - Fixed rsync include rules order to properly sync frontend build files to remote server
• ACL URL Encoding - Fixed ACL deletion, LUN mapping, and LUN unmapping to properly URL-decode IQNs from request paths (colons in IQNs like iqn.2016-04.com.open-iscsi:c8e34e60ec9 were being sent as %3A)
• ACL Creation Auto-Remove LUNs - New ACLs start with no LUNs mapped (auto-mapped LUNs are automatically removed) so users have explicit control over which LUNs to map
• ACL IQN Parsing - Fixed GetISCSIACLs to correctly extract IQN from targetcli output (was using parts[0] which was o-, now uses parts[1] for the actual IQN)
• LUN Detection via ConfigFS - Fixed getMappedLUNsForACL to use configfs link file detection instead of parsing targetcli output for more reliable LUN mapping status
• LUN Backstore Detection - Fixed MapLUNToACL to use ls command instead of info command for more reliable backstore path parsing from targetcli output
• LUN Mapping with Existing Symlinks - Fixed LUN mapping to detect and reuse existing symlinks instead of trying to create duplicate symlinks
  • DELETE /api/iscsi/acls/{iqn}/luns/{lun} - Unmap LUN from ACL
  • GET /api/iscsi/acls-for-lun?lun=N - Get all ACLs for a specific LUN
• Target Configuration Change - Disabled auto-ACL generation (generate_node_acls=0) for manual access control
• ACL Models - New ISCSIACL, ISCSIACLMappedLUN, ACLCreateRequest, ACLMapLUNRequest models
• ACL System Functions - GetISCSIACLs(), CreateISCSIACL(), DeleteISCSIACL(), MapLUNToACL(), UnmapLUNFromACL(), GetACLsForLUN()
• LUN Number Display Fix - Fixed regex-based LUN parsing to correctly display LUN numbers (0, 1, 2, etc.) instead of all showing as LUN 0
• Storage Pool Export Modes - Unified storage management with three export modes:
  • File Mode - Mounted filesystem for NFS/Samba sharing (default)
  • iSCSI Mode - Unmounted, available for iSCSI/LVM use
  • Available Mode - Unmounted, reserved for future use
• Export Mode API - POST /api/storage-pools/{name}/export-mode to switch modes
• New iSCSI Architecture - Redesigned iSCSI with single target, multiple LUNs model (enterprise standard)
• LVM Volume Group Management - Separate VG system from storage pools for iSCSI LUNs:
  • VG Creation - Create volume groups from physical devices (RAID arrays, disks)
  • VG Management Tab - New tab in Storage page for managing volume groups
  • Quick VG Creation in iSCSI - Create volume groups directly when creating LVM LUNs
  • VG Deletion - Delete VGs with automatic LUN cleanup
• LVM LUN Backends - Create flexible, resizable LUNs from LVM volume groups (recommended for sharing storage)
• Clear Backend Options - Three LUN backends with clear descriptions:
  • LVM Volume (Flexible) - Create LUNs of any size from VG. Best for sharing storage among clients
  • Block Device (Dedicated) - Use entire disk/RAID for one LUN. Simple but uses whole device
  • File-Based (Testing) - File on disk as LUN. For testing only. Slower performance
• New iSCSI UI - /scsi route with simplified LUN management interface
• Storage Pool Editing - Edit pool name and mount options without deletion
• NFS Path Editing - Change export paths on existing NFS shares
• Storage Pool Dropdown - Quick-select available storage pools when creating/editing NFS exports
• RAID Auto-Naming - System automatically assigns next available device number (e.g., md0, md1) when creating arrays
• Visual Warnings - Confirmation dialogs and warnings when making destructive changes
• Legacy Mount Detection - Automatic detection and support for /mnt/arcanas-disk-* mounts
• iSCSI Auto-Unmount - Mounted devices (including RAID arrays) are automatically unmounted when used as iSCSI backing stores
• Volume Group API - GET/POST /api/volume-groups, DELETE /api/volume-groups/{name}, GET /api/volume-groups/available-devices
• LV Info on LUN Cards - LVM-backed LUNs now display Logical Volume path and size (queried via lvs)

Changed

• iSCSI Access Control Model - Changed from automatic ACL generation to manual per-client ACL management:
  • Breaking Change - Existing clients will lose access until ACLs are created and LUNs are explicitly mapped
  • Benefit - Each client only sees LUNs explicitly mapped to their ACL (improved security and isolation)
  • Migration Required - After upgrade, create ACLs for each client and map their required LUNs
• Target Attribute - Set generate_node_acls=0 to disable automatic ACL generation
• LUN Number Display - Fixed regex-based LUN parsing to correctly display LUN numbers (0, 1, 2, etc.) instead of all showing as LUN 0
• Simplified Storage/iSCSI Workflow - Single "Storage Pool" concept with export modes replaces confusing multiple storage types
• Pool Export Mode - Change pool purpose (File Share ↔ iSCSI) with one API call, automatic mount/unmount
• iSCSI Model - From multiple targets (one per client) to single target with multiple LUNs
• Storage Pool Architecture - MD RAID devices now mount directly at /srv/{poolname} instead of using MergerFS wrapper
• MergerFS Behavior - Now only used for aggregating multiple raw physical disks (JBOD), not MD devices
• Device Selection - Create pool modal filters to show only available (unmounted) devices
• Pool Type Detection - New "legacy" type for old /mnt/arcanas-disk-* mounts, "direct" for new /srv/* mounts
• iSCSI Backing Stores Display - Mounted devices now show as available with "Will be auto-unmounted" message instead of blocked
