sorry, After rereading the post carefully, geez this is not mount problem but LVM problem, you need to add the /dev/hdb lvm to /dev/hda lvm.
you will need to consult the lvm how-to to get this one done. but surely not with mount command. duckz --- In [email protected], "duckzlandd" <[EMAIL PROTECTED]> wrote: > > --- In [email protected], "Gary" <xheralt@> wrote: > First of all this is what i get from reading your post : > > 1. you install linux in /dev/hda and using LVM and its mounting well > 2. you want to mount /dev/hdb to linux > > is that correct? > if its correct, my question is : > 1. is your /dev/hdb formatted / partitioned? even if its partitioned > under windows, dos or other OS its still counted as partitioned. > 2. if its partitioned and FORMATTED with some filesystem (eg. if you > partitioned the drive under windows you should formatted the driver > under NTFS of fat32, if its under dos then it should be fat.), then > you need to find out the RIGHT filesystem format that you format the > drive with. > 3. when you find out the right filesystem format (eg. ntfs / fat) then > you can mount it using command mount -t vfat /dev/hdb /mnt or mount -t > ntfs /dev/hdb /mnt . or edit your /etc/fstab to make it automount > everytime you boot your system. note: for ntfs you will need to > recompile the kernel for ntfs support (use modprobe -l | grep ntfs to > check if you have the ntfs module or not) or get ntfs-3g driver or > captive ntfs for read and write support. > > 4. but seeing your fdisk -l result I dont think that you have > partitioned and formatted your /dev/hdb yet. > > One easy way to check is to boot to windows and see if you can access > /dev/hdb or not. > > if you havent partitioned and formatted the drive yet the you should > do so before mounting it. > > Regards. > duckz > > > > > > > --- In [email protected], "Forum Forum" <forum_86@> wrote: > > > > > hdb has data (in linux file system) which I don't want to lose and > > > want to use after the installation is complete. > > > > > > I did use hda for the installation and hence partitioned it.
