File Systems and Storage
The following features and functionalities related to file systems and storage are deprecated in Oracle Linux 8.
elevator Kernel Command
The elevator kernel command line parameter sets the disk scheduler for all
devices. If you require a different scheduler than what the kernel automatically selects, use
udev rule or the TuneD service to configure the preferred scheduler.
NFSv3 Over UDP
The NFS server no longer opens or listens on a User Datagram Protocol (UDP) socket by default. Therefore, NFSv3 over UDP is disabled and no longer supported.
peripety Package
The peripety package is deprecated. The Peripety storage event
notification daemon parses system storage logs into structured storage events to enable
you investigate storage issues.
VDO Write Modes
-
sync -
async-unsafe -
auto
In place of these modes, async is the recommended write mode to use.
VDO Manager
The VDO Manager is deprecated and is replaced by the LVM-VDO integration. To create VDO
volumes, preferably use the lvcreate command instead.
You can use the /usr/sbin/lvm_import_vdo script in the lvm2
package to convert existing volumes that were created with the VDO Manager. In this manner,
these volumes can be managed through the LVM-VDO integration.
