Very high IOPS on DB SSD after 1.110 deploy

If I decide to delete the piece_expiration DB from these nodes, it will be recreated on start

It will not, the node is unable to recreate only one missing database, so, if you would delete this DB, you need to follow this procedure:

How to fix database: file is not a database error

@mike

and only impact is that GC / BF will have to clean pieces up that was previously in the DB?

yes, but until the next version these pieces could be never cleaned, see

When will "Uncollected Garbage" be deleted?

Current GC doesn’t differentiate between expired and active pieces, because an other chore supposed to delete the objects/segments earlier. Normally it’s fine, but if the other chore is not fast enough, it’s a problem. That’s why we need fixes on both sides…
