NewCluster (currently cephadm, std/io1, zone 3), CE01-03, UPS2
Meredith (RBD on flash, io2, io3) is on UPS2
Suggestion from CF is to have new 9 racks in today's RL-B, UPS1
IPMI and root console credentials:
IMPI never change (unless motherboard is replaced)
root pwd changes 24/48 hours after it is read. We can set it, though.

CEPH-1119: reminded this morning that some cluster mons still not updated to C8:
for VM mons: ai-rebuild while still on nautilus, then upgrade to octopus later
for physical: reinstall, or remove the mgr class from hg_ceph/cluster/mon and create some C8 VMs which run the mgr only.
CEPH-1228: contrary to what we thought, openshift users *have* noticed the O_APPEND client corruptions because of their usage of non-approved kernel 5.12.7. (Corruption happened in some prometheus db which they simply deleted without contacting us). They are updating to 5.13.10 now.
Drupal migration to CephFS seems to be going well. We get a few mds trimming warnings but all seems just transient.
CEPH-1229: LinuxSoft had planned a migration from flax to levinson, but this was paused because they require much less quota than available. (Need at least 65TB to all repos and snapshots). The motivation for this move was to improve performance -- we'll review again if a dedicated MDS can achieve the same without needing to move all the data.
Two tickets open with LinuxSoft about C8 bugs:
efi raid mismatches: INC2926618 (I found a fix -- requires patching grub.cfg)
kernel raid warning: INC2926549 (effects all known C8 and CS8 kernels. no evidence that it's not just a harmless warning)
Regarding Stream 8 mail:
We should restart the migrations to Stream, cautiously at first. All "known" Stream 8 issues impacting Ceph are fixed.
