(it would be a bit very much overhead) rmcp only deletes checkpoints and does nothing to free up disk space, so try the nilfs-clean command. This command forces GC to run. Example: $ sudo nilfs-clean -S 20/0.1 Because your disk usage seems too high, you might want to check the actual usage with the "lssu -l" command before actually running it. This is a kind of debugging command, but it will actually show you the percentage of blocks used per segment (GC unit). $ sudo lssu -l Regards, Ryusuke Konishi
