Linux分区：超过2TB硬盘分区操作.docx

fdisk -l看分区会报错，比如： WARNING: GPT (GUID Partition Table) detected on /dev/sda! The util fdisk doesnt support GPT. Use GNU Parted.所以这个sda就是gpt的。看gpt分区详细内容可用parted，如：parted /dev/sda测试iscsi服务是否正常[root@FocusBackup ~]# service iscsi restart停止 iscsi： [确定][root@FocusBackup ~]# chkconfig iscsi on[root@FocusBackup ~]# iscsiadm -m discovery -t sendtargets -p 31正在启动 iscsid： [确定]31:3260,1 .openfiler:tsn.vmlocalbackup[root@FocusBackup ~]# iscsiadm -m node -T .openfiler:tsn.vmlocalbackup -p 31 -lLogging in to [iface: default, target: .openfiler:tsn.vmlocalbackup, portal: 31,3260] (multiple)Login to [iface: default, target: .openfiler:tsn.vmlocalbackup, portal: 31,3260] successful.查看硬盘设备[root@FocusBackup ~]# fdisk -lDisk /dev/sda: 322.1 GB, 322122547200 bytes255 heads, 63 sectors/track, 39162 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x000a4673Device Boot Start End Blocks Id System/dev/sda1 * 1 26 204800 83 LinuxPartition 1 does not end on cylinder boundary./dev/sda2 26 133282 Linux swap / Solaris/dev/sda3 1332 26109 199023616 83 Linux/dev/sda4 26109 39163 104857600 5 Extended/dev/sda5 26109 39163 104856576 83 LinuxDisk /dev/sdb: 2199.0 GB, 2199023254528 bytes255 heads, 63 sectors/track, 267349 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x000bfa7aDevice Boot Start End Blocks Id System/dev/sdb1 1 267349 2147480811 83 LinuxDisk /dev/sdd: 1099.5 GB, 1099511627776 bytes255 heads, 63 sectors/track, 133674 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0isk /dev/sdd doesnt contain a valid partition tableDisk /dev/sdc: 2199.0 GB, 2199023254528 bytes255 heads, 63 sectors/track, 2673
