[ceph-users] RBD Image can't be formatted - blk_error

Hi everyone! I'm facing a weird issue with one of my CEPH clusters: OS: CentOS - 8.2.2004 (Core) CEPH: Nautilus 14.2.11 - stable RBD using erasure code profile (K=3; m=2) When I want to format one of my RBD image (client side) I've got the following kernel messages multiple time with different sector IDs: *[2417011.790154] blk_update_request: I/O error, dev rbd23, sector 164743869184 op 0x3:(DISCARD) flags 0x4000 phys_seg 1 prio class 0[2417011.791404] rbd: rbd23: discard at objno 20110336 2490368~1703936 result -1 * At first I thought about a faulty disk BUT the monitoring system is not showing anything faulty so I decided to run manual tests on all my OSDs to look at disk health using smartctl etc. None of them is marked as not healthy and actually they don't get any counter with faulty sectors/read or writes and the Wear Level is 99% So, the only particularity of this image is it is a 80Tb image, but it shouldn't be an issue as we already have that kind of image size used on another pool. If anyone have a clue at how I could sort this out, I'll be more than happy ^^ Kind regards!
