Size return by df

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi, 

I got one cephfs with one volume and subvolumes with a erasure coding. 

If I don't set any quota when I run df on the client I got 

0ccbc438-d109-4c5f-b47b-70f8df707c2c/vo   5,8P     78T  5,8P   2% /vo

The 78T seem to be the size use by ceph on disk (on the hardware I mean). And I find that very good. 

But If I set a quota 

setfattr -n ceph.quota.max_bytes -v 109951162777600 vo

then on the same client I got 

0ccbc438-d109-4c5f-b47b-70f8df707c2c/vo   100T     51T   50T  51% /vo

and that are the size of the data (I using erasure 4/2 so 51*1.5 ~ 77 To)

Is they are any way to keep the first answer ?

Regards
