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 ________________________________________ From: [log in to unmask] [[log in to unmask]] on behalf of Adrian Sevcenco [[log in to unmask]] Sent: 03 April 2019 13:29 To: [log in to unmask] 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!
