I have Virtuozzo Containers subscription with installed application "System Administrator Control Panel". The following error appears when try to edit files through File Manager in CP:
CP > System > File Manager > %path% > mark file > Edit > Update
Cannot upload the file: Input/output error..
[2013/08/01 10:31:24] [WARN]  [HSPC::VZAgent::Common::error] VZA error occurs: Cannot send packet to node [2013/08/01 10:31:24] [WARN]  [HSPC::MT::VESrv::FM::upload] ERROR [2013/08/01 10:31:24] [WARN]  [HSPC::CP::FM::editor] Error while try to upload file (ERROR)
The file you are trying to edit through File Manager has incorrect permissions. In File Manager PBA-S works with privileges of user apache. To be able to edit the file it must have proper permissions: be readable by root and executable(editable) by apache. You may test this in the VZ node from the command line:
[root@container ~]# su - apache
-bash-3.2$ cd /path/to/the/file
-bash-3.2$ less FILE
FILE: Permission denied
- If you work with PBA-S 4.2 the problem may be caused by size of editable file – it was not possible to edit files more than 16KB because of packet size limitation. Bug is PBAS-28198 - it has been fixed since version 4.3.
- Change permissions of the file and parent directories - the file should be editable by apache user.
- Upgrade PBA-S to version 4.3 or higher.
