Hello,


running tunefs.lustre during the upgrade, do i have to add the "--param" option when it has been used during the creation fo the fs ?

i.e. lustre fs during creation: 
mkfs.lustre --param="failover.mode=failout" --fsname lustre --ost --mkfsoptions='-i 2097152 -E stride=16 -b 4096' --mgsnode=mds1 at tcp0 /dev/sdb
now upgrading:
tunefs.lustre --param="failover.mode=failout" --fsname lustre --ost --mgsnode=mds1 at tcp0 /dev/sdb

A "-writeconf" is not intended during the upgrade.




How long will it take (approx) to "tunefs" an 8TB OST partition ?

Thanks and Regards
Heiko
