很可能btrfs正在跳过损坏的数据，但是内核在放弃之前仍然尝试访问损坏的驱动器一段时间。根据：https://su...
Hi. Sorry if this is a duplicate, but I wasn't able to find issue on this. I'm using RAID1 on 5 drives, all of the drives were 3 TB. Recently I've had to switch a failed drive to a 4 TB one. And only then I noted, that btrfs balances based on unallocated space on the ...
For example, a SSD drive can remap the blocks internally to a single copy--thus deduplicating them. This negates the purpose of increased redundancy and just wastes filesystem space without providing the expected level of redundancy. The duplicated data/metadata may still be useful to statisticall...

对于Arch系等依赖滚动更新的发行版，Btrfs的快照功能真的是太具有吸引力了。纵使我已经很久没有遇到“滚...
To start using snapraid-btrfs, you need to set up snapper configurations for each data drive that you want snapraid-btrfs to make snapshots of. At runtime, snapraid-btrfs will follow the following procedure to find snapper configs: If the --snapper-configs or --snapper-configs-file command-...
Devices can be of different sizes. However, if one drive in a RAID configuration is bigger than the others, this extra space will not be used. Someboot loaderssuch asSyslinuxdo not support multi-device file systems. Btrfs does not automatically read from the fastest device, so mixing differen...
Remove Volume1 by removing a drive at a time until the Synology decides it's "failed" and can be totally forgotten. As I removed a 2TB drive, I replace it with a 10TB and expanded the new Storage Pool and the Volume2. These expansions take time as there's a complete consistency check...
