Hi all,
I have set nodeep-scrub and noscrub while I had small/slow hardware for the cluster.
It has been off for a while now.
Now we are upgraded with hardware/networking/SSDs and I would like to activate - or unset these flags.
Since I now have 3 servers with 12 OSDs each (SSD based Journals) - I was wondering what is the best way to unset flags - meaning if I just unset the flags, should I expect that the SCRUB will start all of the sudden on all disks - or is there way to let the SCRUB do drives one by one...
In other words - should I expect BIG performance impact or....not ?
Any experience is very appreciated...
Thanks,
