HP MSA2312sa 12塊1TB硬碟,11塊做RAID5,1塊做SPARE。設置后容量為10TB。使用parted將RAID轉化GPT格式,掛載后卻只顯示9TB
掛載后容量顯示減少的問題 ----------------------------------------- [root@localhost ~]# parted -l Model: HP MSA2312sa (scsi) Disk /dev/sda: 9992GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 17.4kB 9992GB 9992GB ext2 dp1 Model: HP MSA2312sa (scsi) Disk /dev/sdb: 9992GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 17.4kB 9992GB 9992GB ext2 dp1 Error: Unable to open /dev/md0 - unrecognised disk label.
