We run MongoDB 4.4.2 in RS to store about 13Tb of data, and in case of deleting some unused datasets from collections we need to reclaim disk space.
For this option we use compact() functionality, but it doesn't work as expect.
wiredTiger["block-manager"]["file bytes available for reuse"] 19963424768
but
db.runCommand({ compact: 'my_collection'})
{
"bytesFreed" : 315392,
"ok" : 1,
"$clusterTime" : {
"clusterTime" : Timestamp(1612200831, 1256),
"signature" : {
"hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
"keyId" : NumberLong(0)
}
},
"operationTime" : Timestamp(1612200082, 1373)
}
and no extra space on disk.
Any ideas?
