File Systems and Storage

The following features, enhancements, and changes related to file systems and storage are introduced in this Oracle Linux 8 release.

Samba Updated to Version 4.19.4

The samba packages are updated to 4.19.4. Notable changes include:

  • The smbget utility is updated to use a common command line parser to handle command line options and provides better authentication handling. This change is significant and can break scripts that depend on smbget because the options interface has changed. Also, you can no longer use the smbgetrc configuration file. For more information about changes to smbget, run smbget --help or see the smbget(1) manual page.

  • An update to the handling of winbind tracing, so that if winbind debug traceid is enabled in the smb.conf file, the winbind service logs the following fields:

    • traceid: shows records belonging to the same request.

    • depth: shows the request nesting level.

  • Samba uses the GnuTLS cryptographic library functionality, to replace its own cryptography implementation.

  • The directory name cache size option is removed.

Before updating Samba and before you start the service, ensure that you back up the database files because downgrading databases isn't supported. When the smbd, nmbd, or winbind services start, Samba automatically updates its tdb database files.

Use the testparm utility to verify the /etc/samba/smb.conf file after updating Samba.

NVME/FC Discovery and Connect

Using the nvme-cli utility, you can discover and connect to NVMe/FC enabled host bus adapters (HBAs). For more information about this feature, see Oracle Linux 8: Managing Storage Devices. For more information about compatible HBA devices, see https://linux.oracle.com/Component_Compatibility_Guide.pdf.
