The error found in that thread, iirc, is that the block size of the disk does not match the block size of the FS and is trying to access the rest of a block at the end of a disk. I also remember that the error didn't cause any problems.
Why raid 6? Rebuilding a raid 6 seems like your cluster would have worse degraded performance while rebuilding the raid after a dead drive than if you only had individual osds and list a drive. I suppose you wouldn't be in a situation of the cluster seeing degraded objects/PGs, so if that is your use case need them it makes sense. From a cross architecture sense, it doesn't make sense.

Hello,
I found some error in the Cluster with dmes -T:

I found the following Post:

Is this a Problem with the Size of the Filesystem itself oder "only"
eine Driver Bug? I ask becaue we habe in each Node 8 HDD with a Hardware
RAID 6 running. In this RAID we have the XFS Partition.
Also we have one big Filesystem in 1 OSD in each Server instead of 1
Filesystem per HDD at 8 HDD in each Server.
greetings
Hauke
