The following are a list of common problems users have with file access.
If you do not see your problem below or a solution does not work, please create a new post on this topic.
Cannot create files
Common Errors Associated
- “No space on device”
Common Resolutions
- If creating a file within your home directory or bigdata, make sure that you are within quota limits using
check_quota homeorcheck_quota bigdata. - Delete files/directories in order to free up enough space to be back within the quota.
- If in bigdata then purchasing additional storage is another option. Increasing the quota for home directories is not supported.
- Some additional documentation is available here: Permissions and Ownership | HPCC
No permissions to create/modify/delete file
Common Errors Associated
- “Permission Denied”
Common Resolutions
- Make sure that you have appropriate permissions to modify the file
- Documentation is available here: Permissions and Ownership | HPCC
- If you are working out of the “shared” folder of your lab, make sure that the owner of the file/directory sets the appropriate permissions such that other users in the lab can modify them.
Accidentally deleted file/directory
Common Errors Associated
- Deletion of file/directory using
rm
Common Resolutions
- Restore file from last snapshot.
