Всем привет! Пытаюсь протестировать инновационную ФС от CEPH - bluestore. С созданием OSD, где block.wal и block.db находятся на размечаемом HDD проблем нет, а вот при попытке вынести block.db на другой, «быстрый» раздел начинаются трудности.
Вводные данные:
/dev/sdc - HDD /dev/sdm - SSD с несколькими разделами, на первом стоит ОС (Ubuntu Server 16.04.3 LTS, ceph 12.2.0 luminous), остальные (5,6,7,8) - пустые разделы.
Делаю так:
ceph-disk prepare --bluestore /dev/sdc --block.db /dev/sdm6
Вот вывод:
Setting name!
partNum is 0
REALLY setting name!
The operation has completed successfully.
prepare_device: OSD will not be hot-swappable if block.db is not the same device as the osd data
prepare_device: Block.db /dev/sdm6 was not prepared with ceph-disk. Symlinking directly.
Setting name!
partNum is 1
REALLY setting name!

Ошибок нет.
Теперь делаю
