Hi Andy,

This was first noticed with an xrootd-fuse client:
# ls /atlas/uct3/data/users/jano/qual/matched/truth
ls: cannot access /atlas/uct3/data/users/jano/qual/matched/truth/ntuple_0.root: No such file or directory
ntuple_0.root
# rpm -q xrootd-fuse
xrootd-fuse-5.3.1-1.el7.x86_64

Then I also tried with the 'xrdfs' tool:
# xrdfs root://uct3-xrd.mwt2.org:1094 ls /atlas/uct3/data/users/jano/qual/matched/truth/ntuple_0.root
[ERROR] Server responded with an error: [3011] No servers have read access to the file
# rpm -q xrootd-client
xrootd-client-5.3.1-1.el7.x86_64

I have tried the same clients on different hosts, which report the same problem.

I have tried restarting the cmsd/xrootd on all 3 servers and the redirector. File is still in the same state.

Advice on how to proceed? 

Thanks much,
Lincoln

For an xroot client, when this occurs, the client automatically asks the
redirector to correct the cache. So, this should not be an issue. On the
other hand, http has no such protocol so the rror persists until the cache
times out. So, what client was getting this error?
