A system notification appears because the destination
file system has limited disk space. JSA cannot complete
a backup with insufficient disk space.
You might receive the following system notification:
Backup: Not enough free disk space to perform backup.
System notifications about limited disk space occur when free
space in the /store/backup/ partition
is less than double the last backup file size. Limited disk space
results from the volume of data and your backup retention period settings.
For more information, see the Juniper Secure Analytics Administration
Guide.
When you configure the retention bucket storage settings, a
global impact occurs on the storage across your JSA deployment.
Disk usage warnings can occur on the JSA console or any managed host in your JSA deployment. To check
disk usage levels, review the monitored partitions on your JSA
console or managed hosts.
- Verify backup partition disk levels.
Use SSH to log in to JSA console or
the managed host.
Type the following command:
df -PTh /store/backup
- Review the backup partition to check the disk utilization
levels.
If the backup partition is greater than double
the last backup file size, identify the location of your backup.
If your backup is on the same file system as the /store/ariel directory, move it to another storage
system.
If your backup is external, check your usage and ensure
that your backup retention period does not require more space than
you have available.
Reduce disk usage on the /store file system.
Consider increasing your external storage size by using
an offboard storage solution such as iSCSI. For more information,
see the Juniper Secure Analytics Configuring Offboard Storage
Guide.
If your JSA backup partition is mounted on
an NFS share, try lowering the retention period for the backup. The
default backup retention period is two days. For more information
on configuring backup retention periods, see the Juniper
Secure Analytics Administration Guide.
