Добрый день! Имею сервер с 4 дисками. По 2 диска собраны в 2 программных raid1 массива /dev/md0 (/dev/sda7+/dev/sdb3) и /dev/md1 (/dev/sdc1+/dev/sdd1). Эти raid массивы объединены в логическую группу LVM, в которой создан один логический том с файловой системой xfs, занимающий весь объем.
Недавно вышел из строя один из дисков (/dev/sdd1) и перестал определяться в системе. Был куплен абсолютно такой же диск и установлен в сервер
Скопировал таблицу разделов на новый диск с рабочего командой
sfdisk -d /dev/sdc | sfdisk /dev/sddДобавил новый диск в /dev/md1 командой
mdadm --manage /dev/md1 --add /dev/sdd1После перезагрузки начинается восстановление, но при достижении 2,3% восстановление обрывается. Диск /dev/sdd1 принимает статус SPARE.
В dmesg выходит ошибка чтения с диска /dev/sdc1.
