RHEL 8 New Features for Experienced Linux Administrators

Red Hat Enterprise Linux 8 includes the Stratis storage manager, which supports the management of collections of block devices to create flexible file systems.

Stratis also provides advanced storage features, like thin provisioning, snapshotting, and monitoring.

The virtual data optimizer (VDO) is a kernel module that uses zero-block elimination, deduplication of redundant blocks, and data compression to reduce disk space usage and minimize replication bandwidth.

Red Hat Enterprise Linux 8 supports NFS 4.2, which includes the new /etc/nfs.conf configuration file, removes the nfsnobody user, and changes the UID and GID of the nobody user and group to 65534.

The nfsconf tool supports the management of the NFS 4.2 server and client configuration files.
