Looking for a command to reclaim disk from Hermes.

Hi @lathanbritz,

If you can still connect to mongodb, can you please try this and let me know if it helped?

$ mongosh
test> use hermes_dev
switched to db hermes_dev
hermes_dev> db.validations.deleteMany({ledger_index: {$lt: 75000000}})
{ acknowledged: true, deletedCount: 3981200 }
hermes_dev> db.runCommand({ compact: 'validations' }) 
{ bytesFreed: 1493123072, ok: 1 }
hermes_dev>

This should delete all validations prior to ledger number 75000000. I will add a PR to Hermes so it does this automatically at user configurable intervals.

online_delete support added to the main branch 59666e70. This would be available in a release soon.
