标题: mount问题请教！
服务器：DS10
系统：True64 4.0F
我有2块硬盘，一块上面有root区和swap 区及g,h区
另一块现在只分成g,h 2个区，上面都做了AdvFs
装好系统以后，我不知道怎么样使用这第2块盘，也就是说
我不知道该怎样把它mount 上去
我自己尝试：mount -t advfs /dev/rz17g /db
结果报 /dev/rz17g on /db:No such domain, fileset or mount directory错
我该怎么做呢？谁能帮帮小弟？？？
谢谢谢谢！！！

还要做如下工作:
1.#mkfdmn /dev/rz17g db_domain
2.#mkfset db_domain db
3.#cd /
4.#mkdir db
5.mount -t advfs db_domain#db /db

NAME

  advfs - A local file system and utilities

DESCRIPTION

  The File System (AdvFS), a file system option on the Tru64 UNIX operating
  system, features rapid crash recovery, high performance, and a flexible
  structure that enables you to manage your file system while it is on line.
  The AdvFS component is licensed with the Tru64 UNIX operating system and is
  available as file system option during installation.

  A set of utilities that expands the capabilities of the AdvFS file system
  is available: The Advanced File System Utilities. These utilities include
  capabilities such as adding volumes without reconfiguring the directory
  hierarchy of the file system, cloning filesets to enable online backup, and
  improving system performance with domain balancing, and file striping.
  Additionally, a graphical user interface (GUI) that simplifies file system
  management is available with the utilities. The Advanced File System Utili-
  ties component is licensed separately from the Tru64 UNIX operating system.

  Using journaling techniques, AdvFS provides faster crash recovery than the
  UNIX file system (UFS), which implements crash recovery using the fsck
  utility.

  In addition to fast restarts, AdvFS ensures that file structures are
  recovered consistently; extends file and fileset sizes to greater than 2
  gigabytes; creates, deletes, and renames files faster than UFS; and pro-
  vides enhanced backup utilities (vdump and vrestore).

  By configuring AdvFS as the root filesystem, the preceding AdvFS features
  are extended to the root filesystem.

  A UFS file system corresponds to a disk partition and is, therefore, lim-
  ited by the size restrictions of that disk. In contrast, AdvFS filesets can
  span all volumes in the file domain.

  AdvFS introduces file system concepts that do not exist for UFS. Under-
  standing the following concepts prepares you for planning, creating, and
  maintaining the AdvFS file system:

+  Volumes

   A volume is any mechanism that behaves like a UNIX block device, such
   as a disk, disk partition, or logical volume that is configured with
   the Logical Storage Manager (LSM).

+  File Domain

   A file domain is a named set of one or more volumes that provides a
   shared storage pool for one or more filesets (see filesets below).

   When you create a file domain using the mkfdmn command, you must
   specify a domain name and one initial volume.  The mkfdmn command
   creates a subdirectory in the /etc/fdmns directory for each new file
   domain. The file-domain subdirectory contains a symbolic link to the
   initial volume.

   You can add additional volumes to an existing file domain by using the
   addvol utility. With each added volume, the addvol utility creates a
   new symbolic link in the appropriate file-domain subdirectory of the
   fdmns directory.

+  Filesets

   A fileset is both the logical file structure that the user recognizes
   and a unit that you can mount.  Whereas you typically mount an entire
   UNIX file system, with the AdvFS you mount the individual filesets of
   a file domain.

   An Advanced File System consists of a file domain with at least one
   fileset that you create using the mkfset command.  For each fileset,
   the mkfset command creates a .tags directory. The .tags directory is a
   permanent directory that is reserved for future use. You cannot
   delete, rename, or add any files to the .tags directory.

+  Clone Fileset

   A clone fileset is a read-only copy of an existing fileset, which you
   can mount as you do other filesets. You create a clone fileset by
   using the clonefset utility. The reason you create and mount a clone
   fileset is to perform an online backup of the existing fileset.

   A clone fileset is a snapshot of the original fileset, capturing and
   fixing the original fileset at a moment in time.    Any changes you make
   to the original fileset will not appear in its clone. For instance,
   new files added to the original fileset will not appear in the clone.
   Changes to data in files in the original fileset will not appear in
   the clone. Also, files that you remove from the original fileset will
   remain accessible in the clone under the names they had when you
   created the clone fileset.

         Note

   Operations supported by the following AdvFS commands will be retired
   in a future release of the Tru64 UNIX operating system and are sup-
   ported only for backward compatibility with operating system ver-
   sions earlier than DIGITAL UNIX Version 4.0: vedquota(8),
   vncheck(8), vquot(8), vquota(1), vquotaon(8), vquotaoff(8), and
   vrepquota(8). The operations supported by these retiring commands
   are also supported by the following commands: edquota(8), ncheck(8),
   quot(8), quota(1), quotaon(8), quotaoff(8), and repquota(8).

  The Advanced File System Utilities are licensed separately from the Tru64
  UNIX operating system and must be purchased separately.  Both the software
  and the reference pages are contained in the separately-licensed product,
  and must be installed before being used. The following list summarizes the
  Advanced File System Utilities commands:

  addvol
   Adds a volume to an existing file domain. See addvol(8).

  advfsd
   Starts the AdvFS graphical user interface (GUI) daemon.

  balance
   Balances the percentage of used space between volumes. See balance(8).

  clonefset
   Creates a read-only copy of a fileset. See clonefset(8).

  dtadvfs
   Starts the AdvFS graphical user interface.  See dtadvfs(8).

  migrate
   Moves the location of a file within a file domain.  See migrate(8).

  mktrashcan
   Attaches directories to a trashcan directory, which stores deleted
   files.  See mktrashcan(8).

  rmtrashcan
   Detaches a specified directory from a trashcan directory.    See
   mktrashcan(8).

  rmvol
   Removes a volume from an existing file domain. See rmvol(8).

  shtrashcan
   Shows the trashcan directory, if any, that is attached to a specified
   directory. See mktrashcan(8).

  stripe
   Interleaves storage allocation of a file across two or more volumes
   within a file domain.  See stripe(8).

RESTRICTIONS

  When configuring root on AdvFS, set up one partition and one fileset in the
  file domain. Multiple volumes are not supported on root.

EXAMPLES

  The following example creates a file domain called accounts_dmn, which con-
  tains rz1c as the initial volume.  The example also creates two filesets,
  credit_fs and debit_fs and mounts both filesets.

   # mkfdmn /dev/rz1c accounts_dmn
   # mkfset accounts_dmn credit_fs
   # mkfset accounts_dmn debit_fs
   # mkdir /mnt/credit /mnt/debit
   # mount -t advfs accounts_dmn#credit_fs /mnt/credit
   # mount -t advfs accounts_dmn#debit_fs /mnt/debit

标题: mount问题请教！
我刚才自己也做了些尝试，正好是和2楼的朋友的方法一样
只是现在还有一个问题：
这样做，就只是在/dev/rz17g上新建了一个domain
第2块盘的g分区是用起来了。那h分区怎么办呢？
如果我现在想把h分区也放在跟g分区同一个domain里
我该怎么做呢？
我说的是现在该怎么做，就是说如何能把h分区也放到我刚才新建的domain里？
感谢大家这么热心的给我答案
非常感谢！！！

由于现在盘上没有重要数据，所以我就直接把/dev/rz17c重做了个domain
请问我这样做，原来在g区的那个domain还会保留么？
另外，如果我盘上有重要的数据，能不能有其他方法
把h区直接加到原来那个domain里？

感谢大家支持，感谢大家帮助！！！

做分区之前，首先要对分区如何划分方法进行全面了解，每个分区要做什么先做好合理的规划，如果乱来，原来的分区上的数据就有可能被破坏的。
如果对/dev/rz17c做了domain的话，就是rz17c整块盘的分区，而原来的g分区估计被破坏掉了。

如果我现在想把h分区也放在跟g分区..........

#addvol /dev/rz17g db_domain

如果想移出
#rmvol /dev/rz17g db_domain

如果rz17g上有重要数据，可以这样作：

#cd /etc/fdmns
#mkdir test_dmn
#cd test_dmn
#ln -s /dev/rz17g
#cd ..
#showfsets  test_dmn  （显示原来建在rz17g上的set名，假设显示hello）
#mount  test_dmn#hello /mnt
#cd /mnt
这样就可以用rz17g上的数据了。

实现这个功能需要花钱买许可证
