yes indeed:

mmdsh -N CesNodes /usr/lpp/mmfs/bin/net cache flush
mmdsh -N CesNodes systemctl restart gpfs-winbind

kind regards

Hi Pieter,

thanks for the useful hint. It helped partially.

Some uidnumbers are now in the correct range. Some others are not.
All the groups are in the wrong range. And this is only on the node
where I have used id or wbinfo in the past. The other node of the new
cluster has the new mappings.

Is there a cache which has to be cleared to get it right?

regards
Christoph

Hi,

you can compare the mapping between the 2 clusters:

/usr/lpp/mmfs/bin/net idmap dump | grep RANGE | sort

We had an issue when migrating from Samba to CES, our domain had to be
first (before ALLOC) to have the same uid mappings. We changed the order
by deleting them and adding them in the correct order:

/usr/lpp/mmfs/bin/net idmap delete range 0
/usr/lpp/mmfs/bin/net idmap delete range 1
/usr/lpp/mmfs/bin/net idmap delete range 2

/usr/lpp/mmfs/bin/net idmap set range 0 S-1-5-.........
/usr/lpp/mmfs/bin/net idmap set range 1 ALLOC
/usr/lpp/mmfs/bin/net idmap set range 2 S-1-.........
