Hi Aaron, 1)Since you mentioned hard links, I would like to add that our data directory itself is a sym-link. Could that be causing an issue ?
2)Yes, there are 0 byte files of the same numbers in Keyspace1 directory 0 Mar 4 01:33 Standard1-g-7317-Compacted 0 Mar 3 22:58 Standard1-g-7968-Compacted 0 Mar 3 23:10 Standard1-g-8778-Compacted 0 Mar 3 23:47 Standard1-g-8782-Compacted ... I restarted the node and it went about deleting the files and the disk space has been released. Can this be done using nodetool, and without restarting ? Thanks.
