Q:

Subversion Can't flush file to disk: Input/output error

The developers on my company can't commit to subversion anymore.
They receive the follow error message in Tortoise.
Can't flush file to disk: Input/output error

Apache error.log
Could not create activity /01_REPO/!svn/act/6a9f9e72-2412-3147-9534-1b23de635229.  [500, #0]
could not begin a transaction  [500, #5]
Can't flush file to disk: Input/output error  [500, #5]

a google search led me to permission and disk space issues but everthing under /01_REPO has permission to user and group "apache"
and there is no problem with disk space
df -h 
/dev/mapper/vg_svnserver-lv_home
                  191G   12G  169G   7% /01_REPO

The subversion log is empty.
Can someone tell me whats is going on or at least give a hint of how to discover the problem?
OBS: 
Oracle Linux 6.6
svnserve 1.6.11
apache 2.2
iptables off
selinux disabled

A:

The problem is in the disk itself, nothing related with subversion.
I tried to use "svnadmin dump" but I can't restore "svnadmin load" so I use svnadmin hotcopy do copy svn repos to another partition.
