在 Ubuntu 16.04 LTS 中掛載硬體 RAID
我為我的伺服器添加了一個硬體 RAID。它與 LSI-MR9361-8i 一起配置為 87TiB RAID 10。
sudo fdisk -l
返回:Disk /dev/sda: 87.3 TiB, 96009698934784 bytes, 23439867904 sectors Units: sectors of 1 * 4096 = 4096 bytes Sector size (logical/physical): 4096 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/sdb: 953.9 GiB, 1024209543168 bytes, 2000409264 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x00005cd0 Device Boot Start End Sectors Size Id Type /dev/sdb1 * 2048 1050623 1048576 512M fd Linux raid autodetect /dev/sdb2 1050624 1052671 2048 1M 83 Linux /dev/sdb3 1052672 17829887 16777216 8G 82 Linux swap / Solaris /dev/sdb4 17829888 2000408575 1982578688 945.4G 5 Extended /dev/sdb5 17831936 2000408575 1982576640 945.4G fd Linux raid autodetect Disk /dev/sdc: 953.9 GiB, 1024209543168 bytes, 2000409264 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x0001d3a4 Device Boot Start End Sectors Size Id Type /dev/sdc1 * 2048 1050623 1048576 512M fd Linux raid autodetect /dev/sdc2 1050624 1052671 2048 1M 83 Linux /dev/sdc3 1052672 17829887 16777216 8G 82 Linux swap / Solaris /dev/sdc4 17829888 2000408575 1982578688 945.4G 5 Extended /dev/sdc5 17831936 2000408575 1982576640 945.4G fd Linux raid autodetect Disk /dev/md1: 945.2 GiB, 1014945021952 bytes, 1982314496 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x3ccf318f Device Boot Start End Sectors Size Id Type /dev/md1p1 63 1445673284 1445673222 689.4G 83 Linux /dev/md1p2 1445673285 1982308544 536635260 255.9G 5 Extended /dev/md1p5 1445673348 1982308544 536635197 255.9G 82 Linux swap / Solaris Disk /dev/md0: 512 MiB, 536805376 bytes, 1048448 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes
當我去掛載 /dev/sda 時,
sudo mount /dev/sda /mnt/UB_RAID
出現以下錯誤。mount: wrong fs type, bad option, bad superblock on /dev/sda, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so.
顯然,我想要 87TiB,但這裡發生了什麼?我應該能夠很容易地安裝它。
謝謝。
您首先必須在塊設備上創建一個文件系統,然後才能掛載它。
例如:
mkfs.xfs /dev/sda
