+=== Issue with connecting via NFS to the new Data Center===
+__Problem description__
+I tried to connect to the new Data Center using NFS protocol, but it was not working.
+__Solution:__
+In case of Ostrava Data Storage you have to insert the line into krb5.conf for [domain_realm] for Ostrava Data Centre, similarly for other new Data Centers.

 === I want to move my data, but I got problem with permissions. ===
+__Problem description:__
+I tried to transfer my data using Globus/rsync protocol, but I got problem with low permissions, see the log below:
+<code>Error (transfer)
+      Endpoint: ducesnet#globusonline (d8eb370a-6d04-11e5-ba46-22000b92c6ec)

+<note important>That issue is typically related to an encrypted files, or files generated by any backup toll.</note>
+__Solution:__
+That issue can be solved by checking and setting correct permissions on desired files/directories directly on the data storage. In case you use any system from Windows family, you can use [[en:navody:terminal_windows:start#moba_permissions|this tutorial]].
+Please connect to the data storage using ssh protocol.
+<code>ssh username@ssh.du1.cesnet.cz</code>
+Now go to the directory, which you wish to check. Here is obvious which files are causing the issue. It is **test1 a testfile1**.
+<code>username@store:~>cd VO_storage-cache_tape
+username@store:~/VO_storage-cache_tape>ls -alh
+total 84K
+drwx-----T    4 username storage  82 May  3 09:57 .
+drwxr-x--- 1378 root     storage 56K May  3 13:30 ..
+d---------    2 username storage  10 May  3 09:56 test1
+drwxr-xr-x    2 username storage  10 May  3 09:56 test2
+----------    1 username storage   0 May  3 09:56 testfile1
+-rw-r--r--    1 username storage   0 May  3 09:56 testfile2
+</code>
+If you wish to look for problematic files/directories in the directory tree, you can use following command:
+<code># find -L . -perm +u-rwx,g-rwx,o-rwx</code>
+Alternatively you can use find command and simultaneously correct missing permissions, see below:
+<code># find -L . -perm +u-rwx,g-rwx,o-rwx -exec chmod u+rX '{}' \;</code>
