Rebuild 的过程中可以认为大部分的 I/O 都是因为 Rebuild 产生的, 这部份不管 Rebuild 时长都是固定的. Rebuild 时间越长, 其他正常的数据访问会增多, 但这应该只占 I/O 的一小部份. TODO: 我还是没有理解 Rebuild Time 和 MTTDL 之间的关系, 也不清楚 Bit Error Rate 在 MTTF, MTBF 占的比重. Referen...
The problem I'm having is that every time I restart the system, the RAID-1 is seen as degraded. It rebuilds fine, but the cycle continues. I read one post here suggesting the need to verify the array after a rebuild before shutting down or restarting. I did ...

A RAID data storage system incorporates permanently empty blocks into each stripe, distributed among all the data storage devices, to accelerate rebuild time by reducing the number of blocks that need to be rebuilt in the event of a failure.Sumanesh Samanta...
After successful installation I rebooted system and noticed by checking /proc/mdstat that it is in rebuild status. Not sure why this is happening but after 1-2 hours or so I rebooted system just to find out that it is going into rebuild again. Each time I reboot /...
but without requiring as much capacity. RAID 5 also offers read performance nearly comparable to RAID 0. However, RAID 5 cannot recover as quickly as a RAID 1 array. In many cases, RAID 1 can provide near instantaneous recovery, while RAID 5 needs time to rebuild the data across their arr...
