1、問(wèn)題復(fù)現(xiàn)方法

使用mdadm命令對(duì)系統(tǒng)兩塊空閑磁盤（sdb、sdc）做RAID 1，之后格式化該RAID盤并掛載，參考命令如下：

mdadm --create /dev/md1 -l 1 -n 2 /dev/sdb /dev/sdc

mkfs.xfs -f /dev/md1

mount /dev/md1 /mnt/

等待一段時(shí)間后檢查/sys/block/md1/md/sync_action狀態(tài)，狀態(tài)為idle時(shí)可以進(jìn)行下一步mdcheck。此問(wèn)題需要/etc/cron.d/mdcheck這個(gè)定時(shí)任務(wù)來(lái)觸發(fā)，由于/etc/cron.d/mdcheck的時(shí)間是周六0點(diǎn)，這里手動(dòng)修改系統(tǒng)時(shí)間為周五的23:59:00，等待約一分鐘后查看/var/log/cron日志，發(fā)現(xiàn)報(bào)錯(cuò)，提示mdadm: command not found，如圖所示：

2、問(wèn)題分析結(jié)果

mdadm包提供的定時(shí)腳本沒(méi)有包含運(yùn)行命令所需的環(huán)境變量信息
