Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

I'm not getting any warnings during the boot of any of the servers,
but I'll take a look closer at the hardware RAID setup when I have
physical access to it tomorrow.

However if the issue was this, wouldn't it be expected to see the same
speeds when DRBD is disabled? As this isn't what I'm seeing.
