Re: Problem about freeing space after a major compaction

Hi Aaron, we had tried invoking a full GC on Cassandra without any success. The space is still used. Regards, Roberto On 29 March 2011 13:12, aaron morton wrote: > Cassandra will request a GC to free compacted SSTables if there is not > sufficient space to write an SSTable or perform a compacti

Re: Problem about freeing space after a major compaction

Cassandra will request a GC to free compacted SSTables if there is not sufficient space to write an SSTable or perform a compaction. Aaron On 29 Mar 2011, at 02:15, Roberto Bentivoglio wrote: > Thanks you again, we're going to update our enviroment. > > Regards, > Roberto > > On 28 March 201

Re: Problem about freeing space after a major compaction

AFAIK, setting gc_grace_period to 0 shouldn't cause this issue. In fact, that what I'm using now in a single node environment like yours. However, I'm using 0.7.2 with some patches. If you are still using 0.7.0, most likely you got hit with this bug. You might want to patch it or upgrade to la

Re: Problem about freeing space after a major compaction

Hi Chen, we've set the gc grace period of the column families to 0 as suggest in a single node enviroment. Can this setting cause the problem? I don't think so... Thanks, Roberto On 28 March 2011 16:54, Ching-Cheng Chen wrote: > tombstones removal also depends on your gc grace period setting. >

Re: Problem about freeing space after a major compaction

tombstones removal also depends on your gc grace period setting. If you are pretty sure that you have proper gc grace period set and still on 0.7.0, then probably related to this bug. https://issues.apache.org/jira/browse/CASSANDRA-2059 Regards,

Problem about freeing space after a major compaction

Hi all, we're working on a Cassandra 0.7.0 production enviroment with a store of data near to 500 GB. We need to periodically remove the tombstones from deleted/expired data performing a major compaction operation through nodetool. After invoking the compaction on a single column family we can see
