I'm trying to upgrade some Linux systems to RHEL 6, but I cannot mount the home directories. I'm using EXT4 for the RHEL 6 system and EXT3 on the RHEL 5 server, which I'm mounting the directory from. I can't just use the mount command; I have to specify -t ext3, and when I do it says, "Special device (server name and mount point) does not exist". It works just fine from all the RHEL 5 machines, just not from this new RHEL 6 machine.

I just rebuilt the machine and used EXT3 as the file system type this time just to test. It produced the same results: It won't mount.

  • You need to clarify if the file system is remote or not. If it's a directly attached device then you mount with ext3/ext4/reiserfs/whatever, if it's somewhere else on the network then you mount is using the type of network file system it's exported with, eg: smb, cifs, nfs. – James Yale Dec 09 '10 at 16:26
  • I tried -t NFS it says wrong FS type – Tom B Dec 10 '10 at 15:14

you need to convert that ext3 to ext4

# umount /dev/sdbx

# tune2fs -O extents,uninit_bg,dir_index /dev/sdbx

# fsck -pf /dev/sdbx

# mount /dev/sdbx

#vi /etc/fstab

#reboot

  • Are you serious? Everything i read says it is backward compatible http://en.wikipedia.org/wiki/Ext4 – Tom B Dec 10 '10 at 15:16

It was a configuration error on my part why it wouldnt mount, but ext4 is backward compatible
