While working on the reboots for the stretch kernel upgrade we ran into a known issue with some firmwares: T216240.
This affected db2073 (T276909) and by upgrading its firmware we got it back.
We need to switchover current s7 primary master to a candidate master, db1136 (T274336) but before doing so, we'd like to upgrade the kernel on that host, which would need a reboot.
@wiki_willy can we get sometime scheduled with eqiad dcops so the host can get upgraded?.
We'd like this to have some high priority as we need to replace s7 primary master soon (scheduled for 23rd March), as it is a host that might run into BBU issues (T258386) and could crash anytime.
Let us know which day/time could work so we can have the host with mysql stopped and powered off.
Thanks!
