Hello ceph-users, Is there any way I can find an object's location in the disk (byte offset)? so if I use dd with the offset I could get the contents of the object. I am using a v12.2.2 ceph cluster with bluestore. I created an EC pool with jerasure plugin and 4+2 stripes. I have found in which disk the object (textfile) I put with rados (/dev/sdac) from the primary pg that the object is stored in.
I've tried bluestore/objectstore tool and blktrace with no luck. The only thing close to what I want is when I exported the rocksdb, I saw the 1/4 of the textfile in a log file. If this is the writeahead log, i think it should pinpoint to where this stripe should be written Thanks, Theofilos Mouratidis
