Hi, as far as I understand it,
you get no real benefit with doing them one by one, as each osd add, can cause a lot of data to be moved to a different osd, even tho you just rebalanced it.
The algorithm determining the placement of pg's does not take the current/historic placement into account, so changing anything at this, could cause any amount of data to migrate, with each change

Hello, I have a ceph cluster with 5 nodes (1 hdd each node). I want to add 5 more drives (hdd) to expand my cluster. What is the best strategy for this? I will add each drive in each node but is a good strategy add one drive and wait to rebalance the data to new osd for add new osd? or maybe.. I should be add the 5 drives without wait rebalancing and ceph rebalancing the data to all new osd? Thank you. _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
