Apache subversion unable to open another ext4 partion svn repository

kushal bhattacharya
Hi,
Whenever I am trying to access repository which is located in another ext4 partition,I get an error as

<D:error><C:error/><m:human-readable errcode="13">
Can't open directory '/media/sense/20457332-fd6a-409d-821d-6bf368ecf6bd/svn': Permission denied
</m:human-readable></D:error>
How to I resolve this error and successfully access it via localhost first
Thanks,
Kushal

The Subversion server process (svnserve or httpd) is unable to access
(read) the path. Adjust the ownership and permissions so that the server
process has the required privileges.

Kushal:

Just as a slight possibility, you might check to see that the SELinux stuff is turned off (use the "sestatus" command).  If it's not disabled/off then you're going to have to allow the http account to access that data by setting the appropriate security context throughout all directories from the root ('/') down to where the SVN data is stored in that 2nd EXT4 partition - and then the entire SVN data tree.

Cheers.

It's not you who needs to access it: it is the account that Apache is running as - at least when running as Apache.
As for "svnserve", it depends on how you've got that setup so to help we need more details.

Make sure the contents of svn.acc file have the entries – to give rw access to the accounts as stated in the following example

 

#======

# Define Groups

[groups]

administrators = admin

 

# Rules allowing/denying access

[reponame:/]

@administrators = rw

#======

 

 

 

Cheers,

Nico: Please state references to these bugs.  I have not heard anything about them.

Setting it to "permissive" is fine if you are going to actually use "audit2allow" to set a policy and then turn things back on.  Otherwise it is slower and accumulating data unnecessarily.

There have been multiple. https://bugzilla.redhat.com/show_bug.cgi?id=692573 shows up in a fast Google search: that was admittedly from 2011. I'll also acknowledge that it's gotten better. A fast search used to show a lot more reports of poor behavior with SELinux entirely disabled.
 
Setting it to "permissive" is fine if you are going to actually use "audit2allow" to set a policy and then turn things back on.  Otherwise it is slower and accumulating data unnecessarily.

In my experience, it's not noticeably slower than running SELinux at all. And "permissive" can be a very useful tool to guide where and how, you arrange Subversion server components for consistentcy with the already activated web server SELinux policies. It's also helpful to point out where your models of web configuration may be a little...... odd, and themselves a source of error.
