Azure 磁盘未标记为 SSD

描述

Azure 的一个已知问题错误地显示为 Azure SSD 磁盘启用的轮换标志。因此，Azure 磁盘未标记为 SSD，并且在尝试配置对象存储磁盘时发生以下错误：

ERROR][2022-08-18T05:26:35+0000]: Rotational device: '/dev/sdf' is not recommended for ceph OSDERROR][2022-08-18T05:26:35+0000]: Rotational device: '/dev/sdf' is not recommended for ceph OSD

解决方案

要解决此问题并将 Azure SSD 磁盘标记为非旋转，请运行以下命令：

echo "0" > "/sys/block/{raw_device_name}/queue/rotational"
echo "KERNEL==\"${raw_device_name}\", ATTR{queue/rotational}=\"0\"" >> "/etc/udev/rules.d/99-ceph-raw-osd-mark-ssd.rules"
udevadm control --reload
udevadm triggerecho "0" > "/sys/block/{raw_device_name}/queue/rotational"
echo "KERNEL==\"${raw_device_name}\", ATTR{queue/rotational}=\"0\"" >> "/etc/udev/rules.d/99-ceph-raw-osd-mark-ssd.rules"
udevadm control --reload
udevadm trigger

示例：

echo "0" > "/sys/block/sdf/queue/rotational"
echo "KERNEL==\"sdf\", ATTR{queue/rotational}=\"0\"" >> "/etc/udev/rules.d/99-ceph-raw-osd-mark-ssd.rules"
udevadm control --reload
udevadm triggerecho "0" > "/sys/block/sdf/queue/rotational"
echo "KERNEL==\"sdf\", ATTR{queue/rotational}=\"0\"" >> "/etc/udev/rules.d/99-ceph-raw-osd-mark-ssd.rules"
udevadm control --reload
udevadm trigger
