[2024-12-26 16:46:42,886] [ERROR] [backup_mount:DB1] Error while exporting restore path

Cause:

  1. The default restore path /mnt/restores is replaced in the Phoenix.cfg file.

  2. The new path does not exist or has stale entries from previous restore attempts.

  3. This conflict prevents successful export of the restore path.

Solution

Follow these steps to resolve the issue:

Step 1: Verify Stale Entries in /etc/exports

Run the following command to check for stale mount entries:
​exportfs -r

If stale entries are present, you'll see output like:
​exportfs: Failed to stat /Phoenix/PBSTEST/DB1/161/data: No such file or directory

Step 2: Clean Up Stale Restore Mount Entries

  1. Open the /etc/exports file:
    ​vi /etc/exports

  2. Locate the stale entries related to the failed restores, such as:
    ​/Phoenix/PBSTEST/DB1/161/data

  3. Delete or comment out the entries using #:

    • To comment out:
      ​# /Phoenix/PBSTEST/DB1/161/data

  4. Save and exit:

    • Press ESC, type :wq, and hit Enter.

Step 3: Correct the Phoenix.cfg File

  1. Open the Phoenix.cfg file:
    ​vi /etc/Phoenix/ORACLE/Phoenix.cfg

  2. Locate the following variable:
    ​ORACLE_RESTORES_BASE_PATH

  3. Set it to the default mount point /mnt/restores or an available, valid mount point:
    ​ORACLE_RESTORES_BASE_PATH = '/mnt/restores'

  4. Save and exit:

    • Press ESC, type :wq, and hit Enter.

Step 4: Restart Phoenix Backup Store Service

  1. Restart the service:
    ​systemctl restart PhoenixBackupStore

  2. Confirm the service is running:
    ​systemctl status PhoenixBackupStore

    The service should show as "active" and "connected" in the Druva console.

Step 5: Retry the Restore

  1. Log into the Druva console.

  2. Initiate the restore operation again.

Key Verification

  • Ensure the updated mount points are valid and accessible.

  • Use the exportfs command to confirm there are no stale entries:
    ​exportfs -v

Following these steps will resolve the PHOENIX127 error and allow the restore process to proceed successfully.
