How do we create the Airwave database backup when we have all the following issues:
1. Available nightly backup on the server was created several days / weeks ago.
2. All the process are down due to insufficient disk space including postgresql.
3. Services will not start and backup command will not run due to insufficient disk space.
Executing any scripts which required db access will return the following.
Please follow the below instruction to free up the reserved disk space.
Run the following command to find the volume directory as marked below.
[root@airwave764 mercury]# df -h
> As per the above command derive the following command based on the VolGroup00-LogVol00 which is the path for the logical partition.
# tune2fs -m 1 /dev/VolGroup00/LogVol00
> Using the above command we will set the reserved-blocks-percentage to 1 from 5 and that will free up the reserve.
