32:487  [...] Please check mount paths on the library [...].

This article describes the resolution for error message 32:487  [...] Please check mount paths on the library [...].

Symptoms

Backup operations go into a Waiting status with error code 32:487.

Causes

Error Code: [32:487] Description: Insufficient disk space. Available mount paths are not enabled for write or have met reserved space limit. Enable/add more mount paths or add more disk space to existing mount paths. Please check mount paths on the library [LIBRARY_NAME]. Source: cvcommserve, Process: MediaManager

When the data path for a given job(s) has either insufficient space or no available mount paths with Read/Write access, jobs will enter a Waiting status with error code 32:487.

Resolution

The error code will indicate which library is affected.  The following can be checked to resolve this issue:

1. Navigate to the affected library and confirm that there is sufficient space available to continue backup operations:

• Under Storage Resources > Libraries, you will be able to see the Capacity and Free Space in your library:  
• If space is insufficient, you might consider adding an additional mount path to the library by right-clicking on the library and selecting Add Mount Path:  
• View the properties of a mount path and check the Allocation Policy tab. Take note of the Reserve Space value (2GB by default)-- a mount path will not be allow to drop below its Reserved Space threshold:

2. Navigate to the affected library and confirm that all enabled mount paths have Read/Write access.  If the only available mount path(s) have only Read access, backups will not be able to run, regardless of free space:

• View the properties of a mount path and check the Sharing tab.  If Access is Read only (as below), you can edit the Device Controller Details:  
• From the drop-down at the top of the Device Controller Details window, select Read/Write and click OK:

3. Run a Data Retention Forecast and Compliance report to help determine whether insufficient space is the result of improper retention settings.

• In the Commcell GUI, click on the Reports tab and then the dropdown for Other Reports and select Forecast:   
• The Data Retention Forecast and Compliance report will allow you view jobs by Library, Storage Policy or Client to determine if the intended retention is being met:
