Linux Mounted iSCSI Storage

Linux Mounted iSCSI Storage

iSCSI is provided to Linux mounts in two ways, an IP map over the iSCSI protocol, and a file-sharing NFS mount. Where the IP mapping via the iSCSI protocol is mounted to Linux as a disk, the IP mapping also requires partitioning the disk and formatting the partition.

Mount Step:

1: Check iSCSI RPM Package

2: Start iSCSI Service and set up boot

3: Find storage for external logical volumes

4: Mapping logical volumes to Linux systems

5: Set boot auto-map

6: Partitioning mapped disks

7: Formatting after partitioning

8: Mount Partition

Note: After the Linux format is finished, the logical volume system file is the Linux type of file system, this logical volume if you want to hang on to the window server will need to punch the logical volume of the new format, the format of the system is the window System file type. In summary, iSCSI storage through IP mapping cannot be mounted to Linux and windows at the same time, and if sharing is required, it is best to store the LUNs as file shares.

   Set up auto-map on boot

   [Email protected] ~]# iscsiadm-m node-t iqn.2004-01.com.storbridge:block02-wt-p 192.16.10.188:3260--op update-n node . startup-v Automatic

   [Email protected] ~]# iscsiadm-m node-t iqn.2004-01.com.storbridge:block01-wt-p 192.16.10.188:3260--op update-n node . startup-v Automatic

   These two are auto-maps on boot

   Partitioning mapped disks

   Because the storage capacity is 12T greater than 2T, can not use different partition Fdisk, only with GPT partition

   Parted/dev/sdb partitioning the/dev/sdb

   Print printing information, which can be seen in this disk size and partition format

   Mklabel GPT

   Mkpart Primary 0% 100%

   Print shows that the disk partition format has changed to GPT.
