Device Mounting Problem

[jklanka]

Hi,

I am trying to mount a harddisk ( hdc ) device.

But when I run "mount -t auto /dev/hdc1 /mnt/hdc/hdc1" then I get

mount: unknown filesystem type 'xfs'

And if I run "mount -t vfat /dev/hdc1 /mnt/hdc/hdc1" then I get

mount: /dev/hdc1 already mounted or /mnt/hdc/hdc1 busy


I have pasted all the out put for the following linux commands. Please help me to sort this problem.

cat /etc/fstab :

Please help

Thanks

sounds like that drive has an xfs filesystem on it that your kernel can't read.

what is in /proc/filesystems? is xfs listed?

[jklanka]

Hi,

cat /proc/filesystems outputs

nodev sysfs
nodev rootfs
nodev bdev
nodev proc
nodev cpuset
nodev binfmt_misc
nodev debugfs
nodev securityfs
nodev sockfs
nodev usbfs
nodev pipefs
nodev futexfs
nodev tmpfs
nodev inotifyfs
nodev eventpollfs
nodev devpts
ext2
nodev ramfs
nodev hugetlbfs
iso9660
nodev mqueue
ext3
nodev rpc_pipefs
nodev autofs

Need to compile xfs into the kernel or as a module and load the module using

modprobe xfs

HTH

Uh, I'm not so sure it's actually XFS. It looks like fdisk thinks it's a "Linux RAID autodetect" (or at least, that's the value that's in the partition table's "type" byte for these partitions). If that's really what it is, then the real filesystem isn't on hdc1, it's on one of the md* devices. (But fdisk won't tell you anything about the md* devices, because Linux RAID devices aren't partitioned. You'd probably have to copy the first few megs out of the md* device into a normal file, then run file on that file, to see what filesystem it has on it.)

Unless, jklanka -- did you specifically set up software RAID on this machine, using various partitions from your hdc hard drive? If not, then ignore this post. :)

[happybunny]

Is there data on the drive you want to keep?

if not, just fdisk it again and carve it up and/or format it anew
