Symptoms
This article provides a resolution path where the disk partitions on an Avamar utility or data node are becoming full. This is due to files which are either surplus, unexpected or consuming unexpectedly large amounts of space. It is not where the problem is due to space consumed by backup data in 'cur' or due to checkpoint overhead.The space that is consumed on the data partitions of an Avamar node is a combination of the following.
The size of the cur directoryThe amount of checkpoint overhead in the cp.XXXXXXXXXX directories (for data nodes).The presence of files that are expected or unexpected files. This could be due to user activity or undesirable behavior.
Cause
See the child articles in the 'resolution' section for a list of possible causes.It may be necessary to log in to Dell Support to view some articles that have yet to be given public visibility.
Resolution
If the node is a data node or a single node Avamar system, check whether space consumed by 'cur' or checkpoint overhead is causing an issue.
Avamar OS Capacity (Resolution Path).
If the space consumed by 'cur' or checkpoint overhead is not the cause of the partition consumption, see the following article.
Avamar - how to identify large files or directories consuming a lot of disk space on an Avamar node.
Once the large files or folders have been identified, review the articles below which describe how to solve the known scenarios. / partition
Avamar - root "/" partition 100% due to tomcat logs.Avamar - Nodes running older OS security rollups (pre 2016-Q2-v7) may experience higher relative space consumption due to a change in behaviour of XFS space allocation.
/data01 or other dataXX partition
Avamar Server /data01 partition filling up due to large files under mc/server_tmp and /usr/local/avamar/var/client.Avamar data partition is full due to disk test files in QA directories.Avamar GSAN goes in admin mode due to difference in the number of sparse files on the data partitions.
/var partition
Avamar - No space left on device" error for /var file system however df -h shows there is space.Avamar: Logs in /var/log directory not rotating - /var is full
