There's no guarantee that new disks can't be faulty. We had this last year when we expanded our cluster with brand new servers and disks, one of the new OSDs failed almost immediately. You can wait and see how often this appears and if it's always the same disk. Just keep it in mind. Zitat von "Szabo, Istvan (Agoda)" <Istvan.Szabo@agoda.com>:

Note that in this case the inconsistencies are not coming from object reads, but from comparing the omap digests of an rgw index shard. This seems to be a result of a replication issue sometime in the past on this cluster. On Fri, Dec 4, 2020 at 10:32 AM Eugen Block <eblock@nde.ag> wrote:

Interesting, your comment implies that it is a replication issue, which does not stem from a faulty disk. But, couldn't the disk have a bit flip? Or would you argue that would've shown as a disk read error somewhere (because of ECC on the disk.) On 12/4/20 10:51 AM, Dan van der Ster wrote:

I had to repair pg and it worked fine, but not sure where this come from. I have this in the log only :/
Thank you.

In my experience inconsistencies caused by IO errors always have a SCSI Medium Error showing up in the kernel logs. (dmesg, journalctl -k, /v/l/messages, ...) (Except in the case of one very bad non-enterprise SMR drive I run at home, not at work). -- dan On Fri, Dec 4, 2020 at 11:03 AM Hans van den Bogert <hansbogert@gmail.com> wrote:
Interesting, your comment implies that it is a replication issue, which does not stem from a faulty disk. But, couldn't the disk have a bit flip? Or would you argue that would've shown as a disk read error somewhere (because of ECC on the disk.)

Note that in this case the inconsistencies are not coming from object reads, but from comparing the omap digests of an rgw index shard. This seems to be a result of a replication issue sometime in the past on this cluster.

Hi,
this is not necessarily but most likely a hint to a (slowly) failing disk. Check all OSDs for this PG for disk errors in dmesg and smartctl.
