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 OSSes for all all OSTs lctl set_param obdfilter.*.sync_journal=0 on all OSSes mount <osts> on all OSSes mount <filesystem> on all clients is correct to do the job? (I hope it isn't neccessary to recreate a FS from scratch.) Many thanks in advance. Cheers -Frank Heckes P.S.: 1.8.1.1 still contains some bugs which have been fixed in 1.8.3. Described setup is for test purpose only, but the procedure shall be used in the final environment (using lustre 1.8.3), too. ------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------ Forschungszentrum Juelich GmbH 52425 Juelich Sitz der Gesellschaft: Juelich Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.
