While the lvconvert --merge command allows for the restoration of a logical volume to a previous state, the behavior of online merges presents a challenge for data integrity. When a merge is initiated while the origin volume
Goal and constraint The intended design uses a pre-upgrade LVM snapshot of the root LV as the rollback path for a failed dnf upgrade on CentOS, with / on LVM and adequate free space in the VG or thin pool. The unresolved point is where that recovery boundary ends. What a root snapshot does not cover A root LV snapshot captures only that volume. /boot is usua
Rocky Linux uses LVM for snapshot-based backups and XFS as the primary filesystem, with metadata journaling intended to preserve consistency across volume group operations. Restoring a snapshot via block-level copy to a logical volume raises uncertainty about deep metadata alignment between the LVM point-in-time state and the XFS on-disk structures after the
