Henrik Ingo commented on CASSANDRA-18260: ----------------------------------------- [~bschoeni] sure, here you go: {quote}{color:#000000}FileStore org.apache.cassandra.db.DirectoriesTest$FakeFileStore@6ddee60f has 30 bytes available, checking if we can write 20 bytes {color} FileStore org.apache.cassandra.db.DirectoriesTest$FakeFileStore@1f87607c has 30 bytes available, checking if we can write 20 bytes FileStore org.apache.cassandra.db.DirectoriesTest$FakeFileStore@4b862408 has 30 bytes available, checking if we can write 20 bytes FileStore org.apache.cassandra.db.DirectoriesTest$FakeFileStore@6ddee60f has 30 bytes available, checking if we can write 20 bytes FileStore org.apache.cassandra.db.DirectoriesTest$FakeFileStore@1f87607c has 19 bytes available, checking if we can write 20 bytes FileStore org.apache.cassandra.db.DirectoriesTest$FakeFileStore@1f87607c has only 0 MiB available, but 0 MiB is needed FileStore org.apache.cassandra.db.DirectoriesTest$FakeFileStore@4b862408 has 30 bytes available, checking if we can write 20 bytes FileStore org.apache.cassandra.db.DirectoriesTest$FakeFileStore@6ddee60f has 30 bytes available, checking if we can write 20 bytes FileStore org.apache.cassandra.db.DirectoriesTest$FakeFileStore@1f87607c has 19 bytes available, checking if we can write 20 bytes FileStore org.apache.cassandra.db.DirectoriesTest$FakeFileStore@1f87607c has only 0 MiB available, but 0 MiB is needed FileStore org.apache.cassandra.db.DirectoriesTest$FakeFileStore@4b862408 has 20971511 bytes available, checking if we can write 26214409 bytes FileStore org.apache.cassandra.db.DirectoriesTest$FakeFileStore@4b862408 has only 20 MiB available, but 25 MiB is needed {quote} Where this is the new row: {quote}FileStore org.apache.cassandra.db.DirectoriesTest$FakeFileStore@4b862408 has only X MiB available, but X MiB is needed {quote} The above is from the unit test, so the error message "{_}Not enough space for compaction, estimated sstables = 1, expected write size = 161228934093{_}" is not there but would happen after this. This reminds me also, I wanted to highlight the question: Do we want to preserve the exact format "1234567 bytes" or "1.2 MiB"? > Add details to Error message: Not enough space for compaction > -------------------------------------------------------------- > > Key: CASSANDRA-18260 > URL: https://issues.apache.org/jira/browse/CASSANDRA-18260 > Project: Cassandra > Issue Type: Improvement > Components: Observability/Logging > Reporter: Brad Schoening > Assignee: Henrik Ingo > Priority: Normal > Fix For: 4.0.x, 4.1.x, 5.x > > Time Spent: 10m > Remaining Estimate: 0h > > When compaction fails, the log message should list a) the free space > available on disk at that point in time and b) perhaps the number and/or size > of the source sstables being compacted. > Free space can change from one moment to the next, so when the below > compaction failed because it needed 161GB, upon checking the server a few > minutes later, it had 184GB free.
