客户端上的 iSCSI LUN - 仅就绪权限

客户端上的 iSCSI LUN - 仅就绪权限

我用过目标命令行创建 LUN。

查看我的配置:

  
o-/ ........................................................................................................................... [...]
  o- 后台存储................................................................................................................ [...]
  | o- 块................................................................................................................ [存储对象:0]
  | o- fileio ................................................................................................ [存储对象:1]
  | | o- disk1 ........................................................... [/disks/disk1.fileio (200.0MiB) 已激活直写功能]
  | | o- 阿鲁阿 ........................................... ................................................ .. [ALUA 组:1]
  | | o- default_tg_pt_gp ......................................................................... [ALUA 状态:活动/优化]
  | o- pscsi ................................................................................................................ [存储对象:0]
  | o- ramdisk ................................................................................................ [存储对象:0]
  o- iscsi ................................................................................................................ [目标:1]
  | o- iqn.2003-01.org.linux-iscsi.svenshost.x8664:sn.df83287c359b ......................................................... [TPG:1]
  | o- tpg1 ...................................................................................................... [gen-acls,no-auth]
  | o- acls ........................................................................................................... [ACL:1]

  | | o-mapped_lun0 .............................................................................. [lun0 fileio/disk1 (rw)]
  | o- luns ................................................................................................................ [LUN:1]
  | | o- lun0 ........................................................... [fileio/disk1 (/disks/disk1.fileio) (default_tg_pt_gp)]
  | o- 门户 ................................................................................................... [门户:1]
  | o- 0.0.0.0:3260 ......................................................................................................... [确定]
  o- 环回................................................................................................................ [目标:0]
  o- vhost ................................................................................................................ [目标:0]
/>

我能够连接到 iSCSI 门户。

登录 [iface: default, target: iqn.2003-01.org.linux-iscsi.svenshost.x8664:sn.df83287c359b, portal: 15.15.130.11,3260] 成功。

但是当我执行 partprobe 时:

# 部分探测
警告:/dev/sdd 无法写入非本地文件(该系统仅能读取该文件)。 /dev/sdd 只读。
// /dev/sdd 无法打开进行写入,文件系统只能进行只读。

如何打开以进行读/写?

您应该在 targetcli 中添加 iSCSI 启动器的 acl。如果您尝试将 iSCSI 目标连接到 Linux 主机,请在此处检查启动器名称:cat /etc/iscsi/initiatorname.iscsi

https://www.thegeekdiary.com/how-to-configure-iscsi-target-and-initiator-using-targetcli-in-centos-rhel-7/

它应该允许将您的目标连接到启动器并将其用于读写操作。

您还可以使用带有 GUI 的 iSCSI 目标。StarWind VSAN 就是一个很好的例子: https://www.starwindsoftware.com/starwind-virtual-san
