#LVM2 2.03.26 has been released (#LVM / #LogicalVolumeManager / #DeviceMapper / #RedHat) https://sourceware.org/lvm2/

The #DeviceMapper #VDO target, which provides block-level deduplication, compression, and thin provisioning, has been merged for #Linux 6.9: https://git.kernel.org/torvalds/c/61387b8dcf1dc0f30cf690956a48768a3fce1810

For more details see https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/plain/Documentation/admin-guide/device-mapper/vdo.rst and https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/plain/Documentation/admin-guide/device-mapper/vdo-design.rst; from the former:

"As a device mapper target, it can add these features to the storage stack, compatible with any file system. The vdo target does not protect against data corruption, relying instead on […]"

Interesting, the #Linux #kernel device mapper target "dm-vdo" that allows deduplication and compression is finally submitted upstream:

v1: https://lore.kernel.org/all/20230509010545.72448-1-corwin@redhat.com/

:tux: Linux 5.1 kann zu Datenverlust führen

Kernel 5.1 hat einen Fehler im Device Mapper eingeführt, der unter bestimmten Umständen zu massivem Datenverlust führen kann. Vorweg sei gesagt, dass der Fehler nur verschlüsselte Systeme betrifft. Wer nicht zu diesem Anwenderkreis gehört, muss sich also keine Sorgen machen.
