==== Notes ==== | ===== Replacing a Failed MergerFS Drive ===== |
| |
| Since MergerFS is frequently used with SnapRAID, replacing a failed MergerFS Drive is part of the final step in recovering a MergerFS / SnapRAID array, as detailed -> [[https://wiki.omv-extras.org/doku.php?id=omv6:omv6_plugins:snapraid#replacing_a_failed_drive_in_mergerfs|here]]. |
| ===== Notes ===== |
| |
* MergerFS, by design, distributes folders and files between multiple hard drives. Accordingly, to gain the ability to recover a hard drive along with other recovery features, users are strongly encouraged to consider the addition of **SNAPRAID** to protect a MergerFS array. Further, -> [[https://wiki.omv-extras.org/doku.php?id=omv6:utilities_maint_backup#backing_up_data|full data backup]] is recommended for recovery from data disasters. | * MergerFS, by design, distributes folders and files between multiple hard drives.
