proxmox笔记2

1、今天终于搞通了proxmox7挂载emc vnx5100的多路径（集群每个节点都要）

需要安装的包：apt install multipath-tools

创建目录/etc/multipath/conf.d/

创建文件/etc/multipath/conf.d/multipath.conf     （貌似这步非必须）

blacklist {
    # Skip the files under /dev that are definitely not FC/iSCSI devices
    # Different system may need different customization
    devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
    devnode "^hd[a-z][0-9]*"
    devnode "^cciss!c[0-9]d[0-9]*[p[0-9]*]"
#    devnode "^sda*"

    # Skip LUNZ device from VNX
#    device {
#        vendor "DGC"
#        product "LUNZ"
#        }
}
#multipaths {
#    multipath {
#        wwid           600601609b703a004686af850502e611
#        alias           pve-vnx5100
#    }
#}

defaults {
    find_multipaths "on" 
    user_friendly_names no 
    flush_on_last_del yes
}

devices {
    # Device attributed for EMC CLARiiON and VNX series ALUA
    device {
        vendor "DGC"
        product ".*"
        product_blacklist "LUNZ"
        path_grouping_policy group_by_prio
        getuid_callout "/lib/udev/scsi_id --whitelisted --device=/dev/%n"
        #path_selector "round-robin 0"
        path_checker emc_clariion
#        features "1 queue_if_no_path"
        hardware_handler "1 emc"
        prio emc
        failback immediate
        rr_weight uniform
#        no_path_retry 60
    }
}

修改/etc/multipath/wwids文件，加入fcsan的wwid，一行一个wwid（貌似最重要的是这步）

/3600601609b703a004686af850502e611/

重启multipathd服务：systemctl restart multipathd

查看多路径是否成功：multipath -ll

2、把上面挂载好的mapper设备进行分区、格式化等（集群在任意一个节点上执行）

 参看这里：https://starslove.me/2020/07/14/proxmox/

查看新挂载的设备：ls /dev/mapper/

 然后分区挂载：

fdisk /dev/mapper/3600601609b703a004686af850502e611

g

n

t

30    ........这里，原文是31，但我的系统30才是Linux LVM

p

w

创建pv:

pvcreate /dev/mapper/3600601609b703a004686af850502e611-part1                .......这里要注意最后的-part1

创建vg:

vgcreage pve-san /dev/mapper/3600601609b703a004686af850502e611-part1

3、创建集群共享存储

在每个节点上运行partprobe扫描并加载其它节点上创建的pve-san

如果没有partprobe，则安装之：apt install parted

登陆集群任一节点管理web: http://节点ip:8006

 

 大功告成，终于把后端的fc-san挂载给PVE集群去用了，明天开始装个虚拟机和做切换、迁移测试
