Hi Miles,
Thanks for your reply.
My zfs situation is a little different from your test. I have a few early
snapshots which I believe would still be sharing most of their data with the
current filesystem. Then later I have snapshots which would still be holding
onto data that is now deleted.
So
I really think there is something wrong with how space is being reported
by zfs list in terms of snapshots.
Stealing for the example earlier where a new file system was created, 10
1MB files were created and then do snap, remove a file, snap, remove a
file, until they are all gone and you are left

Imagine you have a filesystem containing ten 1MB files,
zfs create root/expo
Hi,
Had a look at the new additions from zpool version 13 but I still don't think
it will give me the information I was after.
Here is what I have gathered, can someone correct me if I'm wrong?
1. The USED property for a snapshot only includes the data that is UNIQUE to
that snapshot.
2. The USE

This perl script hacked together by a colleague, given a zfs filesystem,
will tell you how much space is used by the files, and how much by the
snapshots. This has proven helpful in
Hi,
My problem is very similar. I have a bunch of snapshots referring to old data
which has been deleted from the current filesystem and I'd like to find out
which snapshots refer to how much data, and how they are shared amongst the
snapshots and the current filesystem. This is so I can work ou

The sums don't really work that way.
Consider this scenario:
- I create a dataset and copy 1g into it
- I take a snap
We're running a Thumper with Solaris 10_u4 with 127112-11 kernel patch
in production as our mail CIFS/NFS file server. We have a big zpool
consisting of 6 raidz2 groups.
We have quite a few filesystems underneath that. We use TIm Foster's
automatic snapshot service, version 0.10, to do regular s
