USBメモリをマウントする方法
とりあえずUSBメモリを繋ぎ、dmesgコマンドで
[ 744.338016] usb 2-1.3: USB disconnect, device number 3
[ 796.933913] IPv6: ADDRCONF(NETDEV_UP): vnet2: link is not ready

[ 866.708686] sdb: sdb1
[ 866.710141] sd 2:0:0:0: [sdb] Attached SCSI removable diskとか表示してくれるので、/dev/sdb1をマウントすれば良い事が判るが、lsblkコマンドの方が判りやすい
# lsblk

sdb 8:16 1 58.2G 0 disk
└─sdb1 8:17 1 58.2G 0 part 但し、USBメモリにパーテーションを作っていないと
# lsblk

sda 8:0 0 111.8G 0 disk

└─centos-home 253:2 0 53G 0 lvm /home
sdb 8:16 1 58.2G 0 diskの様にtypeがpartの行が無く、mountしようがないのでパーテーションを作ってフォーマットしておく。
このUSBメモリの情報をチェックしてみると、
# fdisk -l /dev/sdb1
Disk /dev/sdb1: 58.2 GiB, 62472060928 bytes, 122015744 sectors

/dev/sdb1p4 27722122 27722568 447 223.5K 0 Empty
Partition table entries are not in disk order.ところが
# mount -t vfat /dev/sdb1 /mnt/usbfm
mount: /mnt/usbfm: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error.そうntfsに対応してないので、だんだんめんどくさくなったので
consoleのストレージでパーテーションとマウントの設定をしよう
少々時間がかかるが
と出来上がる
結果を見てみよう
