ext4 partition size / free space discrepancies
The results from a df on my main drive on my server don't add up. I came close to running out of disk space, I freed 4 gigs a couple of days ago, but we're still getting weird results two days later.
Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda1 78441416 73732352 724536 100% /
Now, by my calculation, 78,441,416 - 73,732,352 = 4,709,064, so there should be over 4 gigs left, not the 724,536K that df is reporting.
I don't see this could be a quota error - though
quota -f apparently isn't an option for Ubuntu and I haven't yet found a command to recompute the quota.
I'm now going through the various directories doing a
du -sk (glad the server seems to have light traffic for a Monday morning) but not sure what that will tell me.
