CentOS 5 :: GDM Could Not Write Authorization File

On Monday i had Centos 5.3 with / and /home in ext3, with no problems (at least i don't remember any problem).But as I decided to use XFS (I have a SSD , and i use a 3D Modeling software called Maya , that it's quite sure it could take advantage of use XFS), i decided to create in my new Solid State Disk , that i recently bought , a swap , a / partition formated in XFS , and a /home partition in XFS too.Then I used a Live cd to copy the contents from the old HDD to the new SSD , using find and Rsync --> (cd /mnt/oldroot/ ; find . -xdev -print0 | rsync -avHx --exclude-from /mnt/rsync-filter . /mnt/newroot/)

Once done , i edited fstab,Menu.lst , install grub in the MBR and i had to use mkinitrd to load the XFS.ko so be able to boot with the new system.All worked fine , although i only could log with the root , my normal user could not log , and a error appeared : GDM could not write your authorization file.This could mean that you are out of disk space or that your home directory could not be opened for writing.In any case it is not possible to login. Contact system administrator.But i remember that prior to Copy all to the new SSD , and use XFS , all was fine, and i was able to log with my user.

So thinking that perhaps the copy did by Rsync was not ok , or something i decided to reinstall Centos, now in a partition in my SSD and try another time , but without using a /home partition neither a normal user ,only using root.The SSD had a Swap , a 32 GB XFS partition and the / of the new Install in ext3 (20 GB ).Once installed Centos 5.3 , I updated only Glibc , yum and Python packages (like said in Centos 5.4 Release notes recommends , but not doing the final yum update)Then i updated only the kernel , to have a XFS supported Kernel , and then i rebooted (I would update all once migrated to xfs)
