Unable to free up space in drive even after deletion of snapshot data in Netgear Nas1002
I have gone through all previous treads on deletion of Snapshot data in this forum. I tried to delete previous snapshots in Admin Page-> Shares -> Snapshots -> Deleted snapshots in each folder. But this did not free up the data in Volume. It still shows 754 GB snapshot data and 1.08 GB Data and Free space: 64 KB. Disk almost Full. Then i also tried to execute the below command in SSH # touch /.force_snapshots_upgrade # systemctl restart readynasd Restarted the NAS system and i could not see the upgraded snapshots file in GUI under Admin Page-> Shares -> Snapshots - Nothing is available to delete. Disk still shows 754 GB snapshot data I am firmware version: 6.9.3 Please hel

Did you try then running a balance, followed by a scrub?
One option is to back up your data, do a factory default, reconfigure the NAS, and then restore your data from the backup.
Thank you for your reply, I have just completed Balance and started scrub, Will give you an update once its done. I want to do factory default as last option. As i do not have 1 TB drive to take backup :-)
Waiting till the data volume is pretty much 100% full before dealing with the problem is far from ideal. If there are snapshots that need upgrading the snapshot upgrade process would require some free space I would think.
Hi Stephen,
I tried running balance and scrub, But that did not help in removing the snapshot data.
I got a new 1 TB drive to take backup and then do a factory default re-set , But unfortunatley i am unable to copy the data from NAS to external Harddrive. I get the status bar mentioning that copy is in progress and after 30 minutes. Its getting termiated without any error. Any alternate way to copy data from NAS to External harddrive ? Appreciate if you can guide me to any link than can share step by step instructions to follow this.
Cheers,
Suman
How are you trying to copy the data now?
Is the external hard drive connected to a PC or is it connected to the NAS?
Hi There,
I'm exactly in the same situation with two Raid 1 Volumes (Array_4 and Array_5)
On "Array_4", I've totally emptied the Share but, as you can see on the screenshot, the snapshots are still using 75% (?) of the volume.
Snapshot has been turned OFF on both volumes but I can't find any "delete" command in the admin web interface allowing to delete the snapshots folder and I get a permission error when trying to delete the snapshots folder or any sub-folder from the Finder on MacOS 10.3.4
I can, of course, destroy and re-create "Array_4" as there is no data on it but I still have a problem with "Array_5"
How can I delete the snapshot folder and regain free space?
Thanks
You could try checking via ssh. Navigate to the volume root and then list btrfs subvolumes with the command line. This will include any snapshots. For instance
root@NAS:~# cd /data
root@NAS:/data# btrfs subvolume list .Thanks, I can easely access the snapshot folder via ssh but i cannot remove it neither its content.
I've tried to rm -r snapshot but access to the files is denied because, as it is written in the terminal after each delete attempt , the system is read only.
The problem occurred when I moved a large amount of file around. I thought that by balancing the volumes I would regain the space used by the snapshot but nothing really happened after the balancing.
I would really like to avoid destroying and recreating the volumes since that will mean moving again large amount og file.
Any suggestion how to delete the snapshot folder?
