DS220+ DSM 7.1.1 | Disk space warning. Deleted a lot of files but unable to gain any disk space.

[Muru]

Hi Ther,
I'm using DS220+ with DSM 7.1.1-42962 Update 5.

Shows a disk space warning. I house keep and deleted many files but the space still remains same. I stop snapshot, disable the recycle option for all. follow the instruction to clear the recycle but still not able to gain anu extra disk space.

Need some guide.

thank you.

That's incomplete. Did you wait until the "root@DS220:" reappeared?

Your screenshot shows your volume at 3.4 TB usage. Of this your /homes folder is using ~2.9 TB. That is where I would start looking. You also have ~0.6 TB in @synologydrive.... I'm curious... is your volume ext4 formatted? Or btrfs.

To explore /homes you can either do that manually, or drill down using the same command set ... for example... and follow the largest use path.

cd /volume1/homes
du -h -d1

This sounds like a job for the Midnight Commander.

I prefer ncdu for this situation

it's a 2 x 4T Raid . using Btrfs.

after deleted the snapshot. i still did not find the free space.

Snapshot consumption can only be determined through the package itself...

To estimate storage usage by snapshots of a shared folder:​

1. Select a shared folder you wish to evaluate snapshot usage of.
2. Click Snapshot > Calculate Size.
3. Select a time range by entering a start date and an end date, and then click Calculate now.
   Note: The minimum time range is 7 days.

AFAIK, snapshots can only be deleted through the package, or by using btrfs commands (which I won't go into here). Also... the "size" that du reports for snapshots does not represent the storage space occupied.

Another concern I saw involved your ABB storage. Look there as well. ABB space use can only be discerned through the package IIRC.
