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
    }
}
