Hi,
We recently updated our storage servers to CentOS 7.6 and our xrootd to v4.9.1
and I am starting to see some odd behavior when checksums are being computed.
The config file is using:
xrootd.chksum max 4 adler32
Some questions:
What is the default value for ofsofs.cksrdsz?
The documentation for xrootd.chksum state that one can use the administrative
interface to list checksum jobs. Are there any examples for this?
On a dataserver that is hosting a file I tried:
export XRD_LOGLEVEL=Dump
xrdadler32 root://localhost//path/to/file
and when I look at the output the item that sticks out is this response from the
server:
[2019-06-23 16:28:04.201142 -0500][Dump ][XRootD ] [localhost:1094]
Got kXR_wait response of 30 seconds to message kXR_query (code: kXR_Qcksum, arg
length: 85): Job resources currently not available.
How do I determine what resources are currently not available?
the output of xrdfs localhost query stats a (somewhat trimmed) looks like:
<stats id="buff">
<reqs>39456910</reqs>
