Я новичок в Сцилле. Я выполнил шаги установки на сайте Scylla , чтобы настроить небольшой кластер Scylla с 4 узлами в моей учетной записи AWS. Я использую Scylla ami на своих инстансах EC2.
Если я остановлю один из инстансов EC2, а затем запустил его снова. Я получаю сообщение Failed mounting RAID volume!, когда пытаюсь перезапустить Scylla.
Я считаю, что мне нужно перемонтировать том RAID, выполнив следующее:
scylla_raid_setup --raiddev /dev/md0 --disks /dev/nvme1n1,/dev/nvme2n1 --update-fstab --root /var/lib/scylla --volume-role all
Однако, когда я затем пытаюсь запустить Scylla, я получаю следующее сообщение об ошибке:
A dependency job for scylla-server.service failed. See 'journalctl -xe' for details.
Похоже, монтирование не удалось, вот логи:

Что делать дальше?
Вот диски:
Disk /dev/nvme1n1: 7500.0 GB, 7500000000000 bytes, 14648437500 sectors

Если я включаю nvme0n1 в диски для scylla_raid_setup, он возвращает: /dev/nvme0n1 is busy.
В противном случае scylla_raid_setup выводит следующее:

Я удалил одну из записей и попытался перезапустить Scylla. Но он все равно не запустился: (
