SOLVED Cannot delete snapshot

[Sir.Robin]

I have a snapshot that won't be deleted. It is supposed to be held for 2 months, but it's still stuck from october and refuses to be deleted.
This is a replicated dataset and it's the same onthe replicated side.

I have two snapshot tasks on this dataset.
Nr. 1 is every day@02:00 except monday and keep for 1 week
Nr. 2 is every week on monday@02:00 and keep for 2 months

This works fine for another dataset.

Code:

@NAS01:~ % zfs destroy vol01/felles@auto-20141002.1743-1w
cannot destroy snapshots: permission denied

So i learned a new command "zfs holds" and it gives me this:

Code:

@NAS01:~ % zfs holds -r vol01/felles@auto-20141002.1743-1w
NAME                                TAG           TIMESTAMP
vol01/felles@auto-20141002.1743-1w  freenas:repl  Thu Oct  2 17:43 2014

I logged in as SU and did this:

Code:

zfs release -r freenas:repl vol01/felles@auto-20141002.1743-1w

And with that the snapshot was automatically destroyed.

It's still on the pull side, but i assume it will dissapear there to afer replication starts tonight.


What does this mean? Why were it beeing held?

Oh yeah.. and i can't see any of my "2 months" snapshots in "previous versions" in windows...?? I could before and i DO see them for my other datasets....

Hmm, that was supposed to be fixed for 9.3: https://bugs.freenas.org/issues/6140.

 

[Sir.Robin]

Is that the same issue?

Replication now seems to work fine. The snapshot dissapeared on the receiving side too.

However, i still cannot see the weekly (created every monday keep for 2months) snapshots in windows previous versions.

Code:

@NAS01] /mnt/vol01/someuser# zfs list -r -t snapshot -o name,creation  vol01/felles
NAME                                CREATION

vol01/felles@auto-20150316.1033-2m  Mon Mar 16 10:33 2015

So i have one snapshot marked with "2m" left created last night.
In previous versions i can see all snaps except for the last one.

This is another dataset:

Code:

@NAS01] /mnt/vol01/someuser# zfs list -r -t snapshot -o name,creation vol01/ftp

Same setup here. I do two snapshot tasks.
First every day except monday. Keep 1 week.
Second is every monday onlu. Keep 2 months.

However i can see all of them in previous versions. Why is this not so for the other datasets snapshots?

 

[Sir.Robin]

So i found out that you now need to choose a snapshot task in your CIFS share config for windows previous versions to be working.
Choosing between my tasks and restarting cifs alows me to see the corresponding snaps.

Now my question is reversed... why then, do the ftp share show snaps from BOTH snapshot tasks?

 

[cyberjock]

Now my question is reversed... why then, do the ftp share show snaps from BOTH snapshot tasks?

What do you mean? Are you saying that the "ftp" dataset is used for FTP and for CIFS and in CIFS it shows snaps for both tasks?

 

[Sir.Robin]

No, it is not used for ftp,. But yes, in cifs (windows previous versions) i can see the snapshots of both tasks at the same time.
