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
