This article specifies the Liferay support policy for Linux Operating Systems when used with Liferay Digital Experience Platform, Liferay Portal EE, or Liferay Commerce ("the product"). It addresses support coverage unique to Linux distributions and not already covered in the generic Operating Systems policy.
For more information please see the Operating Systems policy.
OpenJDK
Please note that some Linux distributions are bundled with OpenJDK. Please check the Compatibility Matrix to ensure the version of OpenJDK present is compatible with the product being utilized.
Subdirectory Limit
In ext2 and ext3 filesystems, the max number of subdirectories in one directory is fixed to 32000. This limitation can cause issues with the product File System Store (File System Store is the default store for document library). If storing document library assets on the filesystem is necessary, the product should be configured to use the Advanced File System Store.
To use the Advanced File System Store, please set in the portal-ext.properties file:
dl.store.impl=com.liferay.portlet.documentlibrary.store.AdvancedFileSystemStore
