incorrect size information

[Rolf Leggewie]

I mounted an online hard disk from strato.de via davfs. The provider allows me 150G of storage of which less than 1G is used. "df -h" returns some funny numbers that have no resemblence to reality.

$ df -h|grep strato
https://webdav.hidrive.strato.com/
                       26G 13G 13G 50% /mnt/strato

This is still unchanged as of today. I would appreciate some help in triaging this. I only seem to experience this with strato.de so I wonder if they are supplying incorrect information somehow.

I believe this is caused by the hoster not implementing quota-available-bytes and quota-used-bytes as defined in RFC 4331 (www.ietf.org/rfc/rfc4331.txt). Nonetheless, even if this is the case, davfs2 should not return some fantasy value.

Here is the information I collected with cadaver from two hosters. The first one is Strato and does not return a value for above variables while the second one does. The second hoster is also showing correctly in df.

Strato as dav host:
