Изъятие сбойного диска из массива¶

Собираем информацию о диске¶

http://serverfault.com/questions/381177/megacli-get-the-dev-sd-device-name-for-a-logical-drive

Нас интересует 'Target Id' из вывода
megacli -ldinfo -Lall -aall

Virtual Drive: 5 (Target Id: 5)
Name                :r0-2-ssd

Поставил lshw, сравниваем 'Target Id' и 'bus info':

bus info: scsi@0:2.5.0
logical name: /dev/sdf

Смотрим какой раздел находится на этом диске:
lvs -o +seg_pe_ranges |grep /dev/sdf

ssd-kvm321-chi-slave-db       ssd   -wi-ao-- 400.00g      /dev/sdf:2560-104959 

Собираем информацию по "Other Error Count: 1".
