Re: [Libguestfs] mount device of 'unknow' filesystem type




the 'file' and 'vfs-type' commands returned "data" and empty string,
and "virt-filesystems --all --long -a XXX"  returned :
Name      Type        VFS      Label  MBR  Size        Parent
/dev/sda  filesystem  unknown  -      -    8589901824  -
/dev/sda  device      -        -      -    8589901824  -

the windows vms are created by vsphere-client or XenCenter using vm-template,
the format of all disks is NTFS.
 
Thanks!

There are lots of possible causes for this:
 
 - You don't have ntfs-3g installed
 
 - /dev/sda isn't a filesystem (maybe /dev/sda1?)
 
 - The filesystem type really is some unknown new thing.
 
(The last one is least likely)
 
Try running the 'file' or 'vfs-type' command on the filesystem, or run
'virt-filesystems --all --long' on the disk and see what it says.
 
Rich.
