Attending: Ste, Jens (chair+mins), Duncan, Daniel, Winnie, RobC, Vip, Patrick 0. OBP Winnie's server's load dropped from 400 processes (24 Dec.) to ~100, and it was happy, Nagios tests passing and all. CMS still reported red status in PhEDEx, although this seems to have been caused by corrupt files. For example, killing supernumerary GridFTP processes would likely cause files to be truncated (as opposed to the whole transfer failing). 1. Happy. 2. Upgrades Rob reports CentOS8 problems with RAID controllers on older Dell R610s. Although Dell is about to drop support for these, they are still in support, so probably worth poking Dell. QMUL have a happy CentOS8 server somewhere, albeit on more recent hardware. Invitation reminder to people to join DOMA groups if they feel they can contribute - it's good for GridPP to contribute, so we can be more confident that it will also work on our stuff, and of course we will be contributing to the Greater Good(tm). BDIIs - DIRAC may only need these to look up which VOs are supported for a given SE (or vice versa, which SEs are available for a given VO). May also look up the path (VOInfoPath). Would be good to understand. Does it depend on GLUE2 or GLUE1? GLUE2 has a recent 2.1 to support cloud, and most recent GLUE 1 is 1.3 IIRC. 3. AOB NOB From Winnie Lacesso to Everyone: 10:05 AM NOT LONG ENOUGH! [expression of consensus on Christmas Break] From rob-currie to Everyone: 10:06 AM I discovered that CentOS8 doesn't support the RAID controllers we use in Edinburgh: https://wiki.centos.org/Manuals/ReleaseNotes/CentOS8.1905#Known_Issues From Winnie Lacesso to Everyone: 10:07 AM Would Linux software raid not suffice? From rob-currie to Everyone: 10:11 AM Software raid is my plan for the OS tbh, at least it will install on a normal sata link From Daniel Traynor to Everyone: 10:17 AM Full details https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/considerations_in_adopting_rhel_8/hardware-enablement_considerations-in-adopting-rhel-8 From rob-currie to Everyone: 10:18 AM Yep, needed by GridPP Dirac to know how to access storage
