Hi Adrian,

The redirector echos your query, so this means it is not supported on the redirector,
however this is not a problem because you want to query the checksum on the data
server anyway.

The data server returns 0:md5 which means it supports md5 and that md5 is the 
default one (if it would support more checksum types you would see something
like: 0:md5,1:zcrc32,2:adler32).

Cheers,
Michal

Subject: query checksum support : how to interpret results

Hi! I am trying to check if the servers support checksumming but
i do not know to to interpret the results ...
For a redirector i get this :
xrdfs <my_redirector> query config chksum
chksum

for storage servers i get this :
xrdfs <my_storage_servers> query config chksum
0:md5

on the redictor the xrootd.chksum is not specified
but all storages have the option
xrootd.chksum max 2 md5

all servers have xrootd 4.9.0

Thank you!
Adrian
