600 gb of unknown files

[atakacs]

Well I have a rather odd situation where there is about 600gb worth of storage space that I can not identify.
All various GUI tools (including storage analyzer) report the expected sizes for the various shares but there are clearly other files (again, worth 600gb) that don't show up.
Is there a tool that will scan everything. If not I guess I will have to resort to SSH...

snapshots? file history?

 

[atakacs]

could be...
but how can I surface the information ?

Under this thread is the title "Similar Threads"... in this one DS220+ DSM 7.1.1 | Disk space warning. Deleted a lot of files but unable to gain any disk space. There are two utilities proposed. I havent used either, but give them a go and report back!

Also this Same Space after deleting files

Thanks - SSH to the rescue. Now I am not sure how to interpret this

root@syno-sx-02:/volume1# du -h -d1
61M    ./@database
56K    ./@userpreference
72K    ./@S2S
3.8M    ./@SynoFinder-log
28K    ./@SynoFinder-etc-volume
685M    ./@appstore
9.7M    ./@appdata
0    ./@apptemp
0    ./@apphome
28K    ./@appconf
72M    ./@ActiveBackup
14G    ./ActiveBackupforBusiness
156K    ./@eaDir
6.5M    ./logs
590G    ./@img_bkp_cache
12K    ./@sharesnap
64G    ./O365Backup
0    ./NFSShare
16K    ./@tmp
668G    .

as I don't see much in the root folder...

is here your 600GB: a cache folder for active backup for business?

14G ./ActiveBackupforBusiness
156K ./@eaDir
6.5M ./logs
590G ./@img_bkp_cache

I have a rather odd situation where there is about 600gb worth of storage space that I can not identify.

If you are referring to this...

That is simply the total space used by volume1

df -h

 

[atakacs]

Duh.. you are obviously quite correct. Somehow missed it.
Thanks
