20221024 / upgrade before boot

PSMN boot will take some time

We are upgrading all backend ($HOME, /Xnfs, services) servers, and it's soooo long…

We MUST wait for all $HOME and shared volumes (/Xnfs) to be OK before starting login machines.

Some clusters might startup without scratches firstly…

EDIT 17:30: “le propre des emmerdes, c'est de voler en escadrilles…”

• one main switch is dead
• one fileserver is dead (but data are OK, scripts and access paths need to be modified)

planning is delayed…
