Hello, I wonder if my problem still relates to the same issue. I was on-site last week and deploying the CEPH cluster is failing Basically preparing the disk is failing. I have to brute-force manually 2-3 times to work as seen below.
1st time: root@hp-3:~# ceph-disk zap /dev/sdk Warning! Disk size is smaller than the main header indicates! Loading secondary header from the last sector of the disk! You should use 'v' to verify disk integrity, and perhaps options on the experts' menu to repair the disk. Caution: invalid backup GPT header, but valid main header; regenerating backup header from main header. Warning! One or more CRCs don't match. You should repair the disk! Invalid partition data! GPT data structures destroyed! You may now partition the disk using fdisk or other utilities. ceph-disk: Error: Command '['/sbin/sgdisk', '--zap-all', '--', '/dev/sdk']' returned non-zero exit status 2 2nd time: root@hp-3:~# ceph-disk zap /dev/sdk Creating new GPT entries. GPT data structures destroyed! You may now partition the disk using fdisk or other utilities. Creating new GPT entries. The operation has completed successfully. root@hp-3:~# ceph-disk zap /dev/sdk Caution: invalid backup GPT header, but valid main header; regenerating backup header from main header. I even downgraded to 3.13 kernel and yet still the same. However when trying on the lab or deploying ceph in a vm environment I can't reproduce the same error. I'm back with the customer on-site next week and this appears to be the major roadblock. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1475247 Title: ceph-disk-prepare --zap-disk hang To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ceph/+bug/1475247/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
