Диски:
/dev/sde - (raid5 -1,4Tб) занято 1,2Тб (vg5)
/dev/sdс1 - новый диск на 500Гб
/dev/sdd1 - новый диск на 1Тб
еще диски системные, на рейде1 средствами ОС и LVM -vg1, но это, думаю
неважно
Задача:
Заменить диски в массиве на более емкие.
Сделал:
Подключил новые диски (на 1Тб и 500Гб) Определились, как dev/sdс и
/dev/sdd Внес их в массив vg5 (pvcreate, vgextend)
потом pvchange -xn /dev/sde, чтобы на него больше не писалось.
дальше pvmove -i 10 /dev/sde:0-238465 /dev/sdd1, чтобы перенести часть
данных на этот диск.
Все нормально перенеслось, 100%, все работает
дальше pvmove -i 10 /dev/sde:238466-357539 /dev/sdс1, чтобы перенести
оставшиеся данные.
Вот здесь он и выдал:

Unable to reactivate logical volume "pvmove0"
То есть, как я понял, он в lvm пометил, что экстенты перенесены, а фс нет.
Через несколько часов сервер завис, пришлось перезапустить. Отключил
самбу. Восстанавливаю из бекапов срочные данные.
Вложения - выводы pvdisplay, vgdisplay, lvdisplay

Олег
