Hi all,
Scrubs only read data that does exist in ceph as it exists, not every sector of the drive, written or not.
Thanks, this does explain it. I just discovered: ZFS had this problem in the past: * https://utcc.utoronto.ca/~cks/space/blog/solaris/ZFSNonlinearScrubs?showcomments#comments OpenZFS solved it in 2017, using two-phase scrubs: * https://github.com/openzfs/zfs/issues/3625 * https://github.com/openzfs/zfs/commit/d4a72f23863382bdf6d0ae33196f5b5decbc48fd Perhaps Ceph can use the same approach; I filed https://tracker.ceph.com/issues/59584 for it. _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
