Dear XRootD experts,

I would like to understand how to correctly set up the parameter cms.space in XRootD. We currently observe error messages like this one on our servers: 

170615 18:42:06 285690 XrootdXeq: alisgm76.15597:26@[::xxx.xxx.xx.x] pub IPv4 login as alisgm76
170615 18:42:06 285690 ofs_open: alisgm76.15597:26@[::xxx.xxx.xx.x] Unable to create /03/01818/8cb7a7f4-51e9-11e7-a169-ef6caac907fd; no space left on device
170615 18:42:06 285690 XrootdXeq: alisgm76.15597:26@[::xxx.xxx.xx.x] disc 0:00:00

In order to solve this issue, I reduced the recalc parameter to 1 minutes and try different thresholds for the "min" and "hwm" parameters as described in [1]. Actually, we have:

cms.space linger 0 recalc 1 min 100g 150g

and the xrootd partition is as follow: 

Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/datavg-data
                      110T  110T  109G 100% /xrootd

I tried to change the value of the hwm parameter (below and above 100g) but without success, the error messages remain. 

Could you please tell me if there is something wrong with my setting? 

Thanks,

Yvan
