Kelsay:<br>Very nearly all space in use is being used by the OS proper and, strangely, far less than required for an install. I could hose the system with an rm -rf / and still not have enough space to install new firmware, due to this phantom disk usage problem.<br>
<br>Andrew: <br>I&#39;m assuming md0 is on one or more of my two disks, but still investigating whether this is safe to do. Researching mdadm-style software RAID is top of my list of things to do in 9-10 hours after work, but not comfortable popping it out just yet/not sure how to tell if this /dev/md0 device is only on one of my disks and not on both, or a third device/onboard flash.<br>
<br>Jack:<br>Sorry about that - I did have the &quot;fsck -n&quot; output, but didn&#39;t want to make my post that much longer. Dumped it here, as well as &quot;df -i&quot; and &quot;du -sxk /&quot; output. The fsck does give multiple free space errors, and df -i only shows 13% of inodes in use.<br>
