[Samba] locking and gfs

[markus neis]

Hi there,I run samba as a PDC and tried to make this PDC high available with
redhat cluster suite and gfs. I experienced the following problem while
doing this:
If I set the option locking = no in smb.conf it takes about 4 minutes to
copy a file of 1GB size. If I set locking = yes it takes about 1 hour. Im
not sure if locking = no sets locking off for all locking options. At least
I need locking for some of my shares. Are there some useful options for gfs
or recommendations?

Thanks, markus
