symlink bug in 2.3.0

Details

    • Bug
    • Resolution: Fixed
    • Critical
    • Lustre 2.4.0

    • None
    • RHEL6.3

    Description

      Symlinks with a destination path that has the exact length of 61 characters don't work.

      For example

      $ ln -s 123456789012345678901234567890123456789012345678901234567890
      $ ls -al
      ls: cannot read symbolic link 123456789012345678901234567890123456789012345678901234567890: Protocol error

      Symlinks with shorter or longer paths work fine. I assume an off-by-one error, since 60 characters seems to be the limit for storing the symlink inside of an inode.

      Lustre 2.2.0 did not have this problem.

            Since this is a server only issue, The client code doesn't need to be patched, I believe this only affects master.
