Snapshots created by Periodic Snapshot Task are not created.

[ArchatParks]

• Lets say I go to Data Protection > Periodic Snapshot Tasks
• I set up a snapshot.
• I sent it to go off once and day and the next one to happen ten minutes from now.
• Twenty minutes go by and a day goes by (just to see if one or the other didn't work).
• If I click on the datasets tab > Manage datasets, then "Manage Snapshots" under "Data Protection" there are no snapshots created.
• Bug report is filed.

Does the status show as Finished on that task? (maybe you need to show the status column)

 

[ArchatParks]

Nope...it never changes off of "pending". Lets say I set it for 11:00AM today, if you keep clicking refresh, "Periodic Snapshot Tasks " it will count down until 11:00AM (the time for it to fire) then changes to the next day but nothing happens (no snapshots are created).

 

[sretalla]

OK, so checking if the snapshots are there is kind of redundant then...

Have you created a fresh task? and what schedule (and other settings) have you set exactly? (maybe a screenshot would help).

 

[ArchatParks]

They were freshly created tasks but I just deleted them all and started all over.

I have three screen shots attached:
1. TruenasCapture_task-create.PNG - shows me creating a brand new task set to go off at 1:10PM (shoudl have all the settings).
2. TruenasCapture_task-menu-after-create1-107PM.PNG - shows the menu at 1:07PM just after I created the task.
3. TruenasCapture_task-menu-after-running-112PM.PNG - shows the menu at 1:12PM just after I created the task.

 

[somethingweird]

How much data is in the pool? Just wondering - I'm assuming the first one is going to take a lot more time then the rest..

 

[ArchatParks]

Also, I noticed that, as soon as I create a task, the file /var/db/system/syslog-53179c7b52fa4a339b6bdedf76998629/log/syslog shows a bunch of errors (may be a coincidence).

The one in the example is 9 GB.

 

[Patrick M. Hausen]

I'm assuming the first one is going to take a lot more time then the rest

ZFS snapshots are instantaneous.

 

[sretalla]

I am seeing a lot of reference to read only filesystem. Is that dataset read only?

 

[ArchatParks]

Nope and when I roll back to TrueNAS-SCALE-22.02.4, it worked just fine.

 

[sretalla]

Sounds like a case of needing to report a bug so it can be sorted out then. Although I see you already did that... please post the link to it here if possible.

 

[ArchatParks]

Done!
