Eu tenho duas partições muito similares, / dev / sdb1 (rotulado 'bigb') e / dev / sdc1 (rotulado 'bigc'). Eu costumava ser capaz de montar os dois usando mount -n -L bigX /mnt/donottouch/localX (com X sendo b ou c ). No entanto, o mount começou recentemente a exigir que eu especifique -t ext4 , mas apenas em bigc .
O bigb é ótimo:
# mount -n -L bigb /mnt/donottouch/localb -vvv
mount: fstab path: "/etc/fstab"
mount: mtab path: "/etc/mtab"
mount: lock path: "/etc/mtab~"
mount: temp path: "/etc/mtab.tmp"
mount: UID: 0
mount: eUID: 0
mount: spec: "/dev/sdb1"
mount: node: "/mnt/donottouch/localb"
mount: types: "(null)"
mount: opts: "(null)"
final mount options: '(null)'
mount: you didn't specify a filesystem type for /dev/sdb1
I will try type ext4
mount: mount(2) syscall: source: "/dev/sdb1", target: "/mnt/donottouch/localb", filesystemtype: "ext4", mountflags: -1058209792, data: (null)
/dev/sdb1 on /mnt/donottouch/localb type ext4 (rw)
Mas, em seguida, erros bigc:
# mount -n -L bigc /mnt/donottouch/localc -vvv
mount: fstab path: "/etc/fstab"
mount: mtab path: "/etc/mtab"
mount: lock path: "/etc/mtab~"
mount: temp path: "/etc/mtab.tmp"
mount: UID: 0
mount: eUID: 0
mount: spec: "/dev/sdc1"
mount: node: "/mnt/donottouch/localc"
mount: types: "(null)"
mount: opts: "(null)"
final mount options: '(null)'
mount: you didn't specify a filesystem type for /dev/sdc1
I will try all types mentioned in /etc/filesystems or /proc/filesystems
mount: you must specify the filesystem type
... a menos que eu especifique -t ext4 :
# mount -n -L bigc /mnt/donottouch/localc -vvv -t ext4
mount: fstab path: "/etc/fstab"
mount: mtab path: "/etc/mtab"
mount: lock path: "/etc/mtab~"
mount: temp path: "/etc/mtab.tmp"
mount: UID: 0
mount: eUID: 0
mount: spec: "/dev/sdc1"
mount: node: "/mnt/donottouch/localc"
mount: types: "ext4"
mount: opts: "(null)"
final mount options: '(null)'
mount: mount(2) syscall: source: "/dev/sdc1", target: "/mnt/donottouch/localc", filesystemtype: "ext4", mountflags: -1058209792, data: (null)
/dev/sdc1 on /mnt/donottouch/localc type ext4 (rw)
O Mount afirma que tentará "todos os tipos mencionados em / etc / filesystems ou / proc / filesystems", mas claramente não está fazendo isso, já que esses dois arquivos contêm ext4:
# cat /etc/filesystems
ext4
ext3
ext2
nodev proc
nodev devpts
iso9660
vfat
hfs
hfsplus
# cat /proc/filesystems
nodev sysfs
nodev rootfs
nodev bdev
nodev proc
nodev cgroup
nodev cpuset
nodev tmpfs
nodev devtmpfs
nodev binfmt_misc
nodev debugfs
nodev securityfs
nodev sockfs
nodev usbfs
nodev pipefs
nodev anon_inodefs
nodev inotifyfs
nodev devpts
nodev ramfs
nodev hugetlbfs
iso9660
nodev pstore
nodev mqueue
nodev rpc_pipefs
nodev nfs
nodev nfs4
ext4
nodev fuse
fuseblk
nodev fusectl
nodev autofs
nodev nfsd
ext3
Além disso, por que decidir tentar o ext4 para o bigb, mas tente todos os tipos de sistema de arquivos para o bigc?
Para adicionar a estranheza, o blkid é capaz de detectar o bigc como ext4:
# blkid -o value -s TYPE /dev/sdb1
ext4
# blkid -o value -s TYPE /dev/sdc1
ext4
# mount -V
mount from util-linux-ng 2.17.2 (with libblkid and selinux support)
tune2fs -l mostra que ambas as partições são essencialmente as mesmas, exceto pelo tamanho do inode:
# tune2fs -l /dev/sdb1

Algumas informações extras do sistema:
# cat /etc/system-release
Scientific Linux release 6.4 (Carbon)
# uname -ar

lsblk --fs parece soluçar no bigc:
# lsblk --fs /dev/sdb1
NAME FSTYPE LABEL UUID MOUNTPOINT
sdb1 ext4 bigb 2ceadc5b-c302-43d1-b289-047069a15537 /mnt/donottouch/localb
# lsblk --fs /dev/sdc1
NAME FSTYPE LABEL UUID MOUNTPOINT
sdc1 /mnt/donottouch/localc
# e2label /dev/sdc1
bigc
Nenhum deles está em / etc / fstab ou / etc / mtab. Ambos são limpos de acordo com o e2fsck. Alguma ideia? A única mudança recente significativa que posso pensar é uma atualização do Scientific Linux 6.1 para 6.4.
eu acho que o tipo de partição do sdb1 está configurado para 83, o que indica um fs do Linux como o Ext4. Enquanto o sdc1 parece estar configurado para algum outro tipo, de acordo com sua saída de lsblk .
você pode modificar o tipo de partição por meio de utilitários como fdisk ou cfdisk . se bem me lembro, em fdisk você pode alterá-lo usando o comando t e depois inserindo 83.
