Hey,

In our local galaxy install using the latest release january, uploaded datasets are showing empty. But when you download it the contents are there, also if you click auto-detect in edit attributes it will remove the empty status and allow peeking and such. If you upload via ftp the dataset does not show up as empty. We are setting the metadata on our cluster if this is of any help.

Hi Eric,

You'll probably need to disable attribute caching. From the doc[1]:

You may also find that you need to disable attribute caching in your filesystem. In NFS this is done with the -noac mount option (Linux) or -actimeo=0 (Solaris). The attribute cache can prevent Galaxy from detecting the presence of output files or properly reading their sizes. Note that there is some performance trade-off here since all attributes will have to be read from the file server upon every file access.
