The following hosts from the same batch have had BBU issues:
db1074 T231638 s2 slave (sanitarium master)
db1075 T233534 s3 master
db1077 T225391 was s3 host, now test host
The following hosts are also part of the batch and are working fine at the moment but I would assume they can suffer the same thing sooner or later, so we should make sure they are not masters
db1076 s2 slave
db1078 s3 slave
db1079 s7 slave (sanitarium master)
I am not fully sure if we can trust these hosts for a long time (they are also out of warranty since May 2019), maybe we should buy 6 new hosts to replace these?
@mark
These hosts were initially scheduled to be refreshed in March 2021
