Automatic Garbage collector error on delete backup.

Dark26 · Sep 3, 2020

Bonjour,

I have this message on the task list :


2020-09-03T00:00:00+02:00: starting garbage collection on store Backup_Day
2020-09-03T00:00:00+02:00: task triggered by schedule 'daily'
2020-09-03T00:00:00+02:00: Start GC phase1 (mark used chunks)
2020-09-03T00:00:09+02:00: TASK ERROR: Unable to open dynamic index "/Backup_Day/ct/198/2020-08-26T01:00:04Z/root.pxar.didx" - No such file or directory (os error 2)

Indeed, the backup doesn't exist , i delete it to make space. ( i think i did it in the pbs interface, not in the pve interface )

But if i run in manual it's work :

I have this message on the task list :

Did the message appear again? You might have just ran into a race where you deleted it just as the GC was starting. Couldn't think of anything else, the automatic and manual GC use the same code internally...

If it happens again let me know, I'll take a look either way.

I will tell if the problem appears tommorow or if i can reproduce it.

Also had this error, quite easy to reproduce if you set the same schedule for pruning and gc on a datastore (eg, "daily" for both)

i have this option too ( daily both )

Maybe possible to set a différent time between the 2 tasks when the same schedule is set.

this is definitely a bug, I'll take a look.
