"store is getting too big" on monitors after Firefly to Giant upgrade

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

We recently upgraded our cluster to Giant from.  Since then, we’ve been driving load tests against CephFS.  However, we’re getting “store is getting too big” warnings from the monitors and the mons have started consuming way more disk space, 40GB-60GB now as opposed to ~10GB pre-upgrade.  Is this expected?  Is there anything I can do to ease the store’s size?

Thanks!
