我有一个4x 2tb raid 5 mdadmarrays，我已经开始成长到第五盘。
~# mdadm --add /dev/md1 /dev/sdb ~# mdadm --grow /dev/md1 --raid-devices=5 在成长过程中，我收到了一封电子邮件;
A Fail event had been detected on md device /dev/md/fubox:1. It could be related to component device /dev/sdf. Faithfully yours, etc. PS The /proc/mdstat file currently contains the following: Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md1 : active raid5 sdb[5] sdd[0] sdc[1] sdf[2](F) sde[4] 7814051840 blocks super 1.2 level 5, 512k chunk, algorithm 2 [5/3] [UU_U_] [=======>.............] recovery = 39.8% (779268708/1953512960) finish=212.4min speed=92101K/sec

我重新启动并尝试

sdf上的事件数量比较less，并且尝试过组装

然而，在39.8％/ dev / sdf退出，我现在正在运行smartctl -H /dev/sdf
4个原装硬盘是三星HD204UI 2TB，新硬盘是WD 2TB RED
HD204UI驱动器2010年12月或以后生产包括固件补丁（我的印章是2011+）
任何提示如何进行？
