"Insufficient free extents (0) in volume group..."
Отправлено Rom1, 13-Ноя-09 15:19

Есть система, установлен XenServer 5.5
В системе 5 HDD, 4х1000Гб (для хранения данных) и 1х500Гб (для XEN'а и для репозитори виртуальных машин.
После аварийного выключения сервера, отвалились репозитори с террабайтниками, причем все разом. Эти диски, к стати, забиты под завязку файлами. Включил журналирование lvm, там есть вот такие строчки:
lvcreate.c:700   Insufficient free extents (0) in volume group VG_XenStorage-df407f16-69fe-0933-b073-be001cd36a0d: 1 required
Т.е. чего-то не хватает, но не пойму чего. В поиске наткнулся на способ решения проблемы через удаление какого-нибудь lvm, и типа все заработало. Но никак не пойму чего и для чего надо удалить.
Вот выводы команд:
