我有以下有趣的實驗。我使用即時 USB 來安裝 ubuntu 伺服器 12.04 i386 和 webmin 在插入 intel ss4200-e 的 USB 上，我想用它製作一個無頭 samba 伺服器。 webmin在分區選單上顯示以下情況：
Disk name Total size Make and model Partitions Actions
SCSI device A 7.39 GB Kingston DataTraveler 3.0 3 Identify drive
SATA device B 953.83 GB ATA Hitachi HDE72101 1 IDE parameters | Identify drive
SATA device C 953.83 GB ATA Hitachi HDE72101 1 IDE parameters | Identify drive
SATA device D 953.83 GB ATA Hitachi HDE72101 1 IDE parameters | Identify drive
SATA device E 953.83 GB ATA Hitachi HDE72101 1 IDE parameters | Identify drive
突襲選單顯示：
Device name Status RAID level Usable size Member disk devices
/dev/md0 clean RAID5 (Distributed Parity) 2.60 TB /dev/sdb1 | /dev/sdc1 | /dev/sdd1 | /dev/sde1
然後 \dev\md0 選項卡顯示
Device file /dev/md0
UUID fcf48163:7efca14a:7bb08b15:81161d20
RAID level RAID5 (Distributed Parity)
Filesystem status Used in LVM VG volume
Usable size 2794526208 blocks (2.60 TB)
Persistent superblock? Yes
Layout left-symmetric
Chunk size 128 kB
RAID status clean
Partitions in RAID SATA device B partition 1
SATA device C partition 1
SATA device D partition 1
SATA device E partition 1
fstab 看起來像這樣：
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
# / was on /dev/sdb1 during installation

# swap was on /dev/sdb5 during installation

例如，如何在啟動時將 /dev/md0 安裝到 /mnt/raidarray 中？
答案1
假設您的區塊設備 /dev/md0已格式化，您可以發出以下命令：
sudo blkid /dev/md0
這將為您提供一個 UUID，並且通常會告訴您它的格式化檔案系統。
然後將以下行新增到您的/etc/fstab
UUID=the-uui-blkid-gave-you /mnt/raidarray file-system-you-used defaults 0 0
然後鍵入sudo mount -a，您的裝置應該已安裝。請注意該目錄/mnt/raidarray應該存在。
