hey folks, I was deploying a new set of NVMe cards into my cluster, and while getting the new devices ready, it seems the device names got mixed up, and I managed to to run "sgdisk --zap-all" and "dd if=/dev/zero of="/dev/sd" bs=1M count=100" on some of the active devices. I was adding new cards so I could migrate off the 2k+2m erasure coded setup to a more redundant config, but in my mess up I ran the commands above on 3 of the 4 devices before the ceph status changed and I noticed the mistake. I managed to restore the LVM partition table from backup but it seems to not be enough to restart the OSD... I just need to recover one of the 3 drives to save all of my VM+Docker backing filesystem. I'm running on Kubernetes with Rook, after restoring the partition table it seems to be starting up ok, but then I get a stack trace and the container goes into Error state: https://pastebin.com/5wk1bKy9 Any ideas how to fix this? Or somehow extract the data and put it back together? -- Cheers, Peter Sarossy Technical Program Manager Data Center Data Security - Google LLC. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
