I was examining a node to see how it failed after getting a "No space left on device" error when pushing lots of PDF and Word docs at an index. Logging into the machine and using df, I see I have no disk space on this virtual machine.

Free is an estimation of how much free space is in the drive, available is a more accurate computation of it. You should use available. On Sep 27, 2012, at 8:27 PM, P.
