红帽全球峰会10.2.9. 验证 LVM 配置
查看 LVM 配置
根据两个 NVMe 设备和四个 HDD 的示例，应创建以下逻辑卷(LV)：
每个 HDD 放置在两个 NVMe 设备（/dev/nvme0n1 上的两个 LV，两个在 /dev/nvme1n1 上）
每个 HDD 放置一个数据 LV（每个 HDD 个 LV）
每个存储桶索引有一个日志 LV（/dev/nvme0n1 上的一个 LV，/dev/nvme1 上的一个 LV）
每个 bucket 索引中的一个数据 LV 放置在两个 NVMe 设备上（一个 LV 在 /dev/nvme0n1 上，一个 LV on /dev/nvme1n1）
可以在
lsblk 和lvscan输出中看到 LV。在上图的示例中，Ceph 应当有 12 个 LV。作为粗略的检查，您可以对 Ceph LV 进行计数以确保至少有 12 个 LV，但最好确保在正确的存储设备（NVMe 与 HDD）上创建了适当的 LV。lsblk输出示例如下所示：[root@c04-h01-6048r ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 465.8G 0 disk ├─sda1 8:1 0 4G 0 part │ └─md1 9:1 0 4G 0 raid1 [SWAP] ├─sda2 8:2 0 512M 0 part │ └─md0 9:0 0 512M 0 raid1 /boot └─sda3 8:3 0 461.3G 0 part └─md2 9:2 0 461.1G 0 raid1 / sdb 8:16 0 465.8G 0 disk ├─sdb1 8:17 0 4G 0 part │ └─md1 9:1 0 4G 0 raid1 [SWAP] ├─sdb2 8:18 0 512M 0 part │ └─md0 9:0 0 512M 0 raid1 /boot └─sdb3 8:19 0 461.3G 0 part └─md2 9:2 0 461.1G 0 raid1 / sdc 8:32 0 1.8T 0 disk └─ceph--hdd--vg--sdc-ceph--hdd--lv--sdc 253:4 0 1.8T 0 lvm sdd 8:48 0 1.8T 0 disk └─ceph--hdd--vg--sdd-ceph--hdd--lv--sdd 253:5 0 1.8T 0 lvm sde 8:64 0 1.8T 0 disk └─ceph--hdd--vg--sde-ceph--hdd--lv--sde 253:10 0 1.8T 0 lvm sdf 8:80 0 1.8T 0 disk └─ceph--hdd--vg--sdf-ceph--hdd--lv--sdf 253:11 0 1.8T 0 lvm sdg 8:96 0 1.8T 0 disk sdh 8:112 0 1.8T 0 disk sdi 8:128 0 1.8T 0 disk sdj 8:144 0 1.8T 0 disk sdk 8:160 0 1.8T 0 disk sdl 8:176 0 1.8T 0 disk sdm 8:192 0 1.8T 0 disk sdn 8:208 0 1.8T 0 disk sdo 8:224 0 1.8T 0 disk sdp 8:240 0 1.8T 0 disk sdq 65:0 0 1.8T 0 disk sdr 65:16 0 1.8T 0 disk sds 65:32 0 1.8T 0 disk sdt 65:48 0 1.8T 0 disk sdu 65:64 0 1.8T 0 disk sdv 65:80 0 1.8T 0 disk sdw 65:96 0 1.8T 0 disk sdx 65:112 0 1.8T 0 disk sdy 65:128 0 1.8T 0 disk sdz 65:144 0 1.8T 0 disk sdaa 65:160 0 1.8T 0 disk sdab 65:176 0 1.8T 0 disk sdac 65:192 0 1.8T 0 disk sdad 65:208 0 1.8T 0 disk sdae 65:224 0 1.8T 0 disk sdaf 65:240 0 1.8T 0 disk sdag 66:0 0 1.8T 0 disk sdah 66:16 0 1.8T 0 disk sdai 66:32 0 1.8T 0 disk sdaj 66:48 0 1.8T 0 disk sdak 66:64 0 1.8T 0 disk sdal 66:80 0 1.8T 0 disk nvme0n1 259:0 0 745.2G 0 disk ├─ceph--nvme--vg--nvme0n1-ceph--journal--bucket--index--1--nvme0n1 253:0 0 5.4G 0 lvm ├─ceph--nvme--vg--nvme0n1-ceph--journal--sdc 253:1 0 5.4G 0 lvm ├─ceph--nvme--vg--nvme0n1-ceph--journal--sdd 253:2 0 5.4G 0 lvm └─ceph--nvme--vg--nvme0n1-ceph--bucket--index--1 253:3 0 729.1G 0 lvm nvme1n1 259:1 0 745.2G 0 disk ├─ceph--nvme--vg--nvme1n1-ceph--journal--bucket--index--1--nvme1n1 253:6 0 5.4G 0 lvm ├─ceph--nvme--vg--nvme1n1-ceph--journal--sde 253:7 0 5.4G 0 lvm ├─ceph--nvme--vg--nvme1n1-ceph--journal--sdf 253:8 0 5.4G 0 lvm └─ceph--nvme--vg--nvme1n1-ceph--bucket--index--1 253:9 0 729.1G 0 lvmlvscan的输出示例如下：[root@c04-h01-6048r ~]# lvscan ACTIVE '/dev/ceph-hdd-vg-sde/ceph-hdd-lv-sde' [<1.82 TiB] inherit ACTIVE '/dev/ceph-hdd-vg-sdc/ceph-hdd-lv-sdc' [<1.82 TiB] inherit ACTIVE '/dev/ceph-hdd-vg-sdf/ceph-hdd-lv-sdf' [<1.82 TiB] inherit ACTIVE '/dev/ceph-nvme-vg-nvme1n1/ceph-journal-bucket-index-1-nvme1n1' [5.37 GiB] inherit ACTIVE '/dev/ceph-nvme-vg-nvme1n1/ceph-journal-sde' [5.37 GiB] inherit ACTIVE '/dev/ceph-nvme-vg-nvme1n1/ceph-journal-sdf' [5.37 GiB] inherit ACTIVE '/dev/ceph-nvme-vg-nvme1n1/ceph-bucket-index-1' [<729.10 GiB] inherit ACTIVE '/dev/ceph-nvme-vg-nvme0n1/ceph-journal-bucket-index-1-nvme0n1' [5.37 GiB] inherit ACTIVE '/dev/ceph-nvme-vg-nvme0n1/ceph-journal-sdc' [5.37 GiB] inherit ACTIVE '/dev/ceph-nvme-vg-nvme0n1/ceph-journal-sdd' [5.37 GiB] inherit ACTIVE '/dev/ceph-nvme-vg-nvme0n1/ceph-bucket-index-1' [<729.10 GiB] inherit ACTIVE '/dev/ceph-hdd-vg-sdd/ceph-hdd-lv-sdd' [<1.82 TiB] inherit
