They all just started having read errors. Bus resets. Slow reads. Which is one of the reasons the cluster didn't recover fast enough to compensate.
I tried to be mindful of the drive type and specifically avoided the larger capacity Seagates that are SMR. Used 1 SM863 for every 6 drives for the WAL.
Not sure why they failed. The data isn't critical at this point, just need to get the cluster back to normal.

56 OSD, 6-node 12.2.5 cluster on ProxmoxWe had multiple drives fail(about 30%) within a few days of each other, likely faster than the cluster could recover.Hov did so many drives break?Jesper
