我做了以下有趣的实验。我使用实时 usb 在插入 intel ss4200-e 的 usb 上安装了 ubuntu server 12.04 i386 和 webmin,我想用它制作一个无头 samba 服务器。webmin 在分区菜单上显示以下情况:
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
突袭菜单显示:
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
然后显示 \dev\md0 选项卡
Device file /dev/md0

RAID level RAID5 (Distributed Parity)
Filesystem status Used in LVM VG volume

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 如下所示:
# /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>

例如,如何在启动时将 /dev/md0 挂载到 /mnt/raidarray?
答案1
假设您的块设备 /dev/md0
已格式化,您可以发出以下命令:
sudo blkid /dev/md0
这将为您提供一个 UUID,通常会告诉您它是在哪种文件系统中格式化的。
然后将以下行添加到您的/etc/fstab
UUID=the-uui-blkid-gave-you /mnt/raidarray file-system-you-used defaults 0 0
然后输入sudo mount -a
,你的设备应该就挂载了。请注意,目录/mnt/raidarray
应该存在。
