Смотрим состояние логического устройства
![]()
Если после запуска arcconf rescan 1 диск не добавился и массив не стал ребилдиться, то переводим новый HDD в hotspare состояние и ребилд массива начнется
root@rescue ~ # arcconf getconfig 1 ld Controllers found: 1 ---------------------------------------------------------------------- Logical device information ---------------------------------------------------------------------- Logical device number 0 Logical device name : Xen RAID level : 5 Status of logical device : Degraded Size : 2086902 MB Stripe-unit size : 256 KB Read-cache mode : Enabled MaxIQ preferred cache setting : Enabled MaxIQ cache setting : Disabled Write-cache mode : Enabled (write-back) Write-cache setting : Enabled (write-back) Partitioned : Yes Protected by Hot-Spare : No Bootable : Yes Failed stripes : Yes Power settings : Disabled -------------------------------------------------------- Logical device segment information -------------------------------------------------------- Segment 0 : Present (0,0) 9VS3YTBB Segment 1 : Present (0,1) 9VS3WVC2 Segment 2 : Missing Command completed successfully.
в предпоследней строке видим что один из трех HDD вообще не отвечает, заменяем его.
Теперь выводим физические устройства
root@rescue ~ # arcconf getconfig 1 pd
Controllers found: 1

видим Device #2 c "State: Ready" это как раз новый HDD который поставили взамен сбойного
Запускаем следующую команду, после которой новый диск должен автоматически добавится в RAID массив и запустится процесс ребилда
arcconf rescan 1
Выводим состояние логического устройства
root@rescue ~ # arcconf getconfig 1 ld ... Segment 0 : Present (0,0) 9VS3YTBB Segment 1 : Present (0,1) 9VS3WVC2 Segment 2 : Rebuilding (0,2) 9VS217GE ...
Выводим статус и прогресс ребилда
root@rescue ~ # arcconf getstatus 1 Controllers found: 1 Logical device Task: Logical device : 0 Task ID : 101 Current operation : Rebuild Status : In Progress Priority : High Percentage complete : 0
arcconf setstate 1 device <channel_device> HSP
channel_device - это номер канала и id диска в этом канале. Узнать его можно выполнив команду
arcconf getconfig 1 pd
поле
Reported Channel,Device(T:L)
Reported Channel,Device(T:L)
После окончания ребилда диск становится в hotspare резерв
root@rescue ~ # arcconf getconfig 1 ld Controllers found: 1 ---------------------------------------------------------------------- Logical device information ---------------------------------------------------------------------- Logical device number 0 Logical device name : Xen RAID level : 5 Status of logical device : Optimal Size : 2086902 MB Stripe-unit size : 256 KB Read-cache mode : Enabled MaxIQ preferred cache setting : Enabled MaxIQ cache setting : Disabled Write-cache mode : Enabled (write-back) Write-cache setting : Enabled (write-back) Partitioned : Yes Protected by Hot-Spare : No Bootable : Yes Failed stripes : Yes Power settings : Disabled -------------------------------------------------------- Logical device segment information -------------------------------------------------------- Segment 0 : Present (0,0) 9VS3YTBB Segment 1 : Present (0,1) 9VS3WVC2 Segment 2 : Spare (0,2) 9VS217GE
Переводим из hotspare в ready
arcconf setstate 1 device <channel_device> RDY
Убеждаемся что массив и диски вернулись в нормальное состояние
