The OCFS2 block size is 4K. I made a script to average the <br>medium mail size, and it's the follow:<br><br>0k to 1k - 8%<br>0k to 2k - 13%<br>0k to 3k - 22%<br>0k to 4k - 35%<br>4.1k to 6k - 15%<br>6.1 to 8k - 10%<br>8.1k to 10k - 9%<br>10.1k to 12k - 7%<br>rest - 24%<br><br>My debug.ocfs2 doesn't has the "-R" option:<br><br># debugfs.ocfs2 -R "stats" /dev/sdb1<br>debugfs.ocfs2: invalid option -- R<br>debugfs.ocfs2 1.2.1<br><br><br>My doubts are:<br><br>4k is a good block size for this situation?<br>How to avoid waste space as now (~50%)?<br>If I choose to use 2k, will the available Inodes double (16M to 32M)?<br><br>Thanks a
