Discussion topics
Time | Item | Presenter | Notes |
---|---|---|---|
XRD-6 | Lockless reads | @Thomas, Jyothish (STFC,RAL,SC) | Met Rob C. on Monday; VR jobs failing still, generally with [socket timeout]. Seems specific within the job submission. Rob C. also looking into the round robin with local tests. Not much change reported by Rob in job success rate. |
XRD-11 | Slow deletions | @Ian Johnson |
|
N/A | Corrupted LHCb file(s) | @Thomas, Jyothish (STFC,RAL,SC) | Caused by write conflict between davs and gridftp. A variety of problematic outcomes observed from replication test. Xrootd/davs takes a couple mins to clean up after reporting failure, during which unexpected behaviours can still arise.
