Reclaiming Disk Space on the Compute Servers

Before you install the Recovery Appliance software, you must run the reclaimdisks script on each compute server. The script checks the volume configuration and reallocates all space correctly for the Recovery Appliance. Reclaiming the disk space converts the Linux system to four disks in a RAID-5 configuration at the disk controller level.

Perform the following steps to configure the disks on a compute server:

1. Log in to the compute server as the root user.

2. Change to the /opt/oracle.SupportTools directory.

3. Start the disk reclamation process:

   # ./reclaimdisks.sh -free -reclaim

   The command frees any preconfigured disks, schedules reclamation of all free disks to Linux on the next boot, and restarts Recovery Appliance. The process may take two hours to complete.

   Caution: Do not restart Recovery Appliance or interrupt the reclamation process.

4. Validate the Linux configuration:

   ./reclaimdisks.sh -check

   The last lines of the output should be the following:

   [INFO]  Valid single boot configuration found for Linux: RAID5 from 4 disks
    with no global and dedicated hot spare disks
   Valid. Booted: Linux. Layout: Linux.

5. Repeat these steps on the other compute servers.
