ReadyNAS RN104 showing space used for snapshots when snapshots set to never

Hello

I have the same problem as this closed topic :

https://community.netgear.com/t5/New-to-ReadyNAS/ReadyNAS-312-showing-space-used-for-snapshots-when-snapshots-set/td-p/1063116

In the RN104, I have 2 disks of 4To only in RAID1, no snapshot parametred (0/never in the snapshot column)  but on the overview there are 747 Go of snapshots !!! That very much and I would like to remove them in order to free space (only 40 go free at present :(  : the system says to run in degrated conditions..)

I performed a "cleaning" of the disks but without changes.

the instruction manual doesn't apply to unseeable snapshots

The system is at the last update : 6.6.1

Please note that I am not in informatician..

 

Ps : another question : what happens if I insert 2 new 4To disks in NAS ? Will I get automatically 8To storage in RAID1- X-RAID ?

    One possibility is snapshots that were not upgraded when updating to 6.2.x (or later) from pre-6.2.x firmware.

     

    What does your btrfs.log look like?

      Thanks for your reply.

      I've updated it to 6.6.1 yesterday, in 2 steps at asked (so I was before 6.2 previously) , hoping it would solve the problem....

      I didn(t asked for snapshot in previous version but maybe it was done by default.

      the log file is quite empty as I've reseted it yesterday too, in case it would earn disk place... :(

        That log file I referred to is generated on demand when downloading all the logs and thus cannot be erased by clearing the logs.

      Unfortunately, I am working with Mac....

      Then it's even easier. Open a terminal and SSH...

        Applications > Utilities > Terminal

         

        # ssh root@ip.address.of.nas

        Hit the enter/return key and you'll then get prompted to enter the password.

  • Hi, I ve launched the 2 orders lines given in the link.... but it didn't change significantly the problem : I won 15go of free space but 700 go of snapshots are still there !!!
    What to do ?

      Hi,

      No answer = no solution ???

      It's becoming critical : I retried the orders but this time, I've got that answer when typing  "systemctl restart readynasd" :

      "Failed to add /run/systemd/ask-password to directory watch: No space left on device"
