We have configured cephfs . Yes i can restore the data. But i need to know which files are corrupted. So that i can delete those files and copy them again. In normal state i can get inode id of files and mapping inode id with object id. So that i can get files to object mapping . using ceph osd map command i can find objects to PG ans OSD mapping.
But once the objects are losts that time how can i find which are the objects lost. Is there any way to list the objects of a PG Regards Surya Balan On Mon, Aug 13, 2018 at 6:12 PM, Janne Johansson <icepic...@gmail.com> wrote: > "Don't run with replication 1 ever". > > Even if this is a test, it tests something for which a resilient cluster > is specifically designed to avoid. > As for enumerating what data is missing, it would depend on if the pool(s) > had cephfs, rbd images or rgw data in them. > > When this kind of data loss happens to you, you restore from your backups. > > > > > Den mån 13 aug. 2018 kl 14:26 skrev Surya Bala <sooriya.ba...@gmail.com>: > >> Any suggestion on this please >> >> Regards >> Surya Balan >> >> On Fri, Aug 10, 2018 at 11:28 AM, Surya Bala <sooriya.ba...@gmail.com> >> wrote: >> >>> Hi folks, >>> >>> I was trying to test the below case >>> >>> Having pool with replication count as 1 and if one osd goes down, then >>> the PGs mapped to that OSD become stale. >>> >>> If the hardware failure happen then the data in that OSD lost.
