This is precisely the point of the discussion. That doesn't work. Observe:
(First of all, what system do you have -% on? I don't have it on either
solaris 10, or rhel 4)
You want to get the atime, ctime, mtime, crtime. I am now repeating what's
already been discussed in this thread. Observe:
The atime, ctime, mtime are all useless. Because here are two different
snapshots, taken on different days, and the mtime etc are identical. You
can't use that information to figure out which is newer, if you distrust the
name of the snap to give you the time of the snap.
It's been mentioned that you can "zfs list -t snapshot" to get them sorted
correctly, but that's the best we've got, and it's only available on the
host itself. Not available on NFS client.
(From the ZFS file server itself)
I haven't found any way to even display the mtime. Neither ls or stat.
This was all I found:
[r...@nas snapshot]# python
>>> import os
>>> os.stat('/share/.zfs/snapshot/daily-2010-04-21-00-00-00')
(16877, 3L, 47514090L, 16, 0, 0, 20L, 1269878840, 1269878847, 1269878847)
>>>
>>> os.stat('/share/.zfs/snapshot/daily-2010-04-20-00-00-00')
(16877, 3L, 47514101L, 16, 0, 0, 20L, 1269878840, 1269878847, 1269878847)
The last 3 are atime, mtime, ctime. All identical.
(From a NFS client, RHEL 4)
[ehar...@air ~]$ stat /share/.zfs/snapshot/daily-2010-04-21-00-00-00
