  Veritas InfoScale (formerly Storage Foundation) provides enterprise-grade HA storage management, clustering, and disaster recovery for Linux and Unix systems. Key components include VxVM (Volume Manager) for disk, volume, and mirror management, and VxFS (File System) for online-resizable filesystems with integrated snapshot support. InfoScale is a legacy enterprise product; modern alternatives include LVM + ext4/XFS (built into Linux), ZFS, and Btrfs for volume/filesystem management. / Veritas InfoScale (ранее Storage Foundation) — корпоративная платформа управления хранилищем, кластеризации и аварийного восстановления. Включает VxVM (Volume Manager) и VxFS (File System). Современные альтернативы: LVM + ext4/XFS, ZFS, Btrfs.

Architecture Overview

Component Summary

VxVM — Volume Manager

Disk Management (vxdisk)

vxdisk list                                     # List all disks / Список дисков
vxdisk -o alldgs list                           # Disks mapped to DGs / Диски в DG
vxdisksetup -i <DEVICE>                         # Initialize disk for VxVM / Инициализировать диск

Disk Groups (vxdg)

# Create Disk Group
vxdg init <DG_NAME> <DISK_NAME>=<DEVICE>

# Add disk to existing DG
vxdg -g <DG_NAME> adddisk <DISK_NAME>=<DEVICE>

# Import / Deport DG
vxdg import <DG_NAME>                           # Import (bring online) / Импортировать
vxdg deport <DG_NAME>                           # Deport (take offline) / Деимпортировать

# List all DGs
vxdg list

[!WARNING] Deporting a DG takes all volumes in that group offline. Ensure no applications are using them before deporting.

Volumes (vxassist)

# Create volume
vxassist -g <DG_NAME> make <VOL_NAME> 10g

# Create mirrored volume
vxassist -g <DG_NAME> make <VOL_NAME> 10g layout=mirror

# Grow volume online
vxassist -g <DG_NAME> growto <VOL_NAME> 20g

# Shrink volume (filesystem must be shrunk first)
vxassist -g <DG_NAME> shrinkto <VOL_NAME> 8g

# Add mirror to existing volume
vxassist -g <DG_NAME> mirror <VOL_NAME>

# Remove mirror
vxassist -g <DG_NAME> remove mirror <VOL_NAME>

Volume States

vxprint -ht                                     # Hierarchy view (all objects) / Иерархия всех объектов
vxprint -g <DG_NAME> -v                         # Volumes in DG / Тома в DG

Device Paths

/dev/vx/dsk/<DG>/<VOL>    # Block device / Блочное устройство
/dev/vx/rdsk/<DG>/<VOL>   # Raw device (for mkfs) / Сырое устройство (для mkfs)

VxFS — Filesystem

Create & Mount

# Create VxFS filesystem
mkfs -t vxfs /dev/vx/rdsk/<DG>/<VOL>

# Mount
mount -t vxfs /dev/vx/dsk/<DG>/<VOL> /mnt/point

# Add to /etc/fstab
echo "/dev/vx/dsk/<DG>/<VOL>  /mnt/point  vxfs  defaults  0 0" >> /etc/fstab

Online Resize

[!TIP] VxFS supports online resize (grow/shrink) without unmounting — a major advantage in production environments.

# Grow volume + filesystem together
vxassist -g <DG_NAME> growto <VOL_NAME> 20g
fsadm -F vxfs -b 20g /mnt/point                # Grow FS to 20 GB / Увеличить ФС до 20 ГБ

# Shrink — must shrink FS FIRST, then volume
fsadm -F vxfs -b 8g /mnt/point                 # Shrink FS / Уменьшить ФС
vxassist -g <DG_NAME> shrinkto <VOL_NAME> 8g   # Then shrink volume / Потом том

Snapshot (VxFS-level)

# Create snapshot volume (same DG)
vxassist -g <DG_NAME> make <SNAP_VOL> 2g layout=mirror

# Mount snapshot
mount -t vxfs -o snapof=/mnt/point \
  /dev/vx/dsk/<DG>/<SNAP_VOL> /mnt/snap

# List snapshots
fsadm -S info /mnt/point

# Remove snapshot
umount /mnt/snap
vxedit -g <DG_NAME> rm <SNAP_VOL>

Filesystem Info

df -h /mnt/point                                # Size and usage / Размер и использование
fsadm -F vxfs -i /mnt/point                    # VxFS info / Информация VxFS
fsck -t vxfs /dev/vx/rdsk/<DG>/<VOL>           # Filesystem check (unmounted) / Проверить ФС

Sysadmin Operations

Service Management

systemctl status vxvm-boot                      # VxVM boot service / VxVM загрузка
systemctl status vxfs                           # VxFS mount service / VxFS монтирование
/etc/init.d/vxvm-boot start                     # Start VxVM boot services / Запустить

VxVM Daemon

vxconfigd start                                 # Start VxVM config daemon / Запустить демон
vxconfigd stop                                  # Stop / Остановить
vxconfigd -m enable                             # Start enabled / Запустить включенным

Log Locations

/var/adm/messages          # System messages (Solaris legacy) / Системные сообщения
/var/log/messages          # System messages (Linux) / Системные сообщения

Troubleshooting

Status Commands

vxprint -ht                                     # Full object hierarchy / Полная иерархия
vxdisk -o alldgs list                           # All disk → DG mapping / Карта дисков к DG
vxprint -g <DG_NAME> -ht                        # Hierarchy for specific DG / Иерархия DG
vxprint -g <DG_NAME> -v                         # Volume details / Детали томов

Disk & Volume Errors

# Check for failed disks
vxdisk list | grep -i fail

# Recover a failed subdisk
vxrecover -g <DG_NAME>

# Rescan disks (after adding hardware)
vxdctl enable

DMP (Multipathing)

vxdmpadm listctlr all                           # List HBA controllers / Список HBA
vxdmpadm getsubpaths dmpnodename=<DEVICE>       # List paths for device / Пути устройства
vxdmpadm enable controller=<CTL>               # Enable path / Включить путь
vxdmpadm disable controller=<CTL>              # Disable path / Отключить путь

Common Fixes

# DG not importing (disk DAEMONIZED state) / DG
vxdg import -f <DG_NAME>                        # Force import / Принудительный импорт

# Volume in DISABLED state
vxvol -g <DG_NAME> start <VOL_NAME>             # Start volume / Запустить том

# Stale NFS mounts preventing deport
umount -f -l /mnt/point                         # Force unmount / Принудительное размонтирование
