Hey, anybody out there who could explain the structure of a rbd-header? After last crash we have about 10 images with a: 2012-03-14 15:22:47.998790 7f45a61e3760 librbd: Error reading header: 2 No such file or directory error opening image vm-266-disk-1.rbd: 2 No such file or directory ... error? I understand the "rb.x.y"-prefix, the 2 ^ 16hex as block-size. But the size/count encoding is not intuitive ;)
Besides one file, where I "created" a header and putted it via "rados put" back into the pool, and got some files back, many of the other images with lost headers have different sizes. We got bad luck again, too many crashed VM's, too much data-loss... Comments welcome ;) Oliver. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
