NFS问题 [英] NFS problem
问题描述
嘿嘿所有..
我在SLES9中的64位环境中使用DB2 8.2。
服务器是HP Proliant DL385
对于存储我正在使用NetApp Fas250文件管理器。
使用一些NFS卷来存储数据库。
让我担心的是一个用于存储实例
用户的卷。
我有一个nfs挂载点/ data / instance /
执行db2安装后，在该挂载点上创建用户db2inst，dasusr和db2fenc
...没问题。
但由于某些原因我无法创建实例。
当我尝试调用db2icrt -w 64 -u db2fenc db2inst时，我得到了以下
错误信息：
DBI1281E数据库管理器配置文件无法初始化为
。
当我将db2inst，dasusr和db2fenc目录复制到同一个挂载点时，
只有没有实际的moun t到位（意思是我在同一个地方有那些dirs
，但现在本地存储）我可以毫无问题地创建实例
。
显然我的NFS设置有问题。
我已经在rw中通过TCP挂载了共享（记住，我可以创建用户
目录）。
是否还需要其他参数来确保db2正确使用的股票是什么？
我检查过的事情：
- 股票上的免费空间
- 股票的权限
- 确保了分享是通过TCP而不是UDP挂载
- 默认设置已经到位
有关这个问题的任何想法吗？
谢谢

Hey hey all..
I''m using a DB2 8.2 in an 64bit environment in SLES9.
Server is a HP Proliant DL385
For storage I''m using a NetApp Fas250 filer.
using a few NFS volumes to store the database.
The one that worries me a bit is a volume meant to store the instance
user(s) on.
I have an nfs mount point /data/instance/
after performing a db2 install, the users db2inst, dasusr and db2fenc
are created on that mount point... No problem.
But for some reason I''m not able to create an instance.
When I try to call db2icrt -w 64 -u db2fenc db2inst I get the following
error message:
DBI1281E The database manager configuration file could not be
initialized.
When I copy the db2inst, dasusr and db2fenc dir to the same mount point,
only without the actual mount in place (meaning that I have those dirs
on the same place, but now locally stored) I can create the instance
without problems.
So obviously there''s something wrong with my NFS settings.
I have mounted the share over TCP in rw (remember, I can create the user
directories).
Are there any other parameters required to ensure the shares are
correctly used by db2?
Things I have checked:
- Free space on the share
- Permissions on the share
- ensured the share is mounted over TCP instead of UDP
- default settings are in place
Any thoughts on this matter?
Thanks

推荐答案
这听起来像db2inst用户标识没有权限写
到已安装的文件系统。您是否已经验证db2inst可以在已挂载的文件系统上写入
目录吗？

This sounds like the db2inst userid does not have the authority to write
to the mounted file system. Have you verified that db2inst can write to
its directories on the mounted file system?

服务器启用了恶意的rw访问，所以每个人都应该能够写入
。
只是为了河畔我改为用户db2inst并在
共享上创建了一个文件。没问题。我可以在其上创建，更改和删除文件。
Phil Sherman写道：
The server has anonyous rw access enabled, so everyone should be able to
write.
Just to be sure I changed to user db2inst and created a file on the
share. No problem. I can create, alter and delete files on it.

此外，实例是由root创建的。因此root需要在NFS卷上拥有_all_
权限。特别是，root必须能够创建
文件，更改所有者和权限。还创建了一些suid文件，
如果你的NFS配置设置正确，那些应该按预期工作
up。你不会有任何机会使用像西葫芦这样的东西吗？

I remember dimly that there were some issues with DB2 databases on NFS. I
don''t remember any details, but you should find something via Google.
Also, the instances are created by "root". So root needs to have _all_
privileges on the NFS volume. In particular, root must be able to create
files, change owners and permissions. Some suid-files are created as well,
and those should work as intended if your NFS configuration is properly set
up. You don''t use something like root-squash by any chance?
