Df not updating solaris


Suppose that you have a ZFS pool with various filesystems, and while the filesystems have data in them, you're just using the pool as a container; the top level pool filesystem has no data itself.In this situation, a Translated, we can see that the pool itself is 300G, the pool's top level filesystem has nothing in it, and there's 40G of unused space left in the pool; the rest is taken up by sub-filesystems, snapshots, and so on.However, if you NFS mount the pool itself on a client and do a df on the client, what you will see is rather different: results on NFS clients.If the pool has enough space left that the filesystem's size is limited by its quota, you will see the correct (quota-based) values for everything.However, if the pool starts running out of overall space the (total) of the (quota-limited) filesystems starts shrinking, sometimes dramatically.All of this can be very alarming and upsetting to users, especially if it leads them to think that they haven't got space that they've paid for.



(Okay, there's a third option: you could return the correct total size and an available space figure that was total size minus the used space.I think this would be even crazier than the other options.)

That's why you see 124G of 130G used, but zero available.

    The problem I found with these solutions is that they do not take into account directory inheritance. Yes, you will find out how much "space" is under a certain directory. But if you want to actually find out how much extra space a zone is taking, you have to go a different route. Do a zonecfg -z zonename info.…

    Jan 13, 2015. This is where du think disk usage, even though your "disk" is probably an SD card comes in. By default, the output is pretty verbose and hard to read, so I usually use -h for human readable numbers with units and -s for a summary. Your browser does not support the video tag.
