Enable async journals
Hi all,
we use SLES 11 and Lustre 1.8.1.1 + patches and like convert a lustre FS
using external journals to one with async journals enabled.
Question is whether the procedure:
umount <filesystem> on all clients
umount <osts> on all OSSes
e2fsck <ost-device> on all OSSes for all all OSTs
tune2fs -O ^has_journal <ost-device> on all
