Hey, in case building from source does not work out for you, here is a strategy we used to recover older systems before: - Create a .tar from /, pipe it out via ssh to another host - basically take everything with the exception of unwanted mountpoints - Untar it, modify networking, hostname, ceph config, etc. - When this is done you have a directory usable as root filesystem suitable on your new monitor - Prepare a new disk using (s)fdisk and friends, filesystem, etc. - Copy/tar over the new filesystem - Add the bootloader to the disk (likely grub or lilo in our case) - Add disk into the new monitor, boot from it This is by far not the cleanest method and it is easy to forget to change old configurations from the source host, but in case you cannot get the binaries from anywhere else, this is a known way for recovery. We have various scripts that we use for bootstrapping servers, checkout [0] for instance which contains most steps from above. I wish you good success for recovering - we are still running some Nautilus clusters, which are also due for upgrade, so I can feel your situation.

Hi,
I have a very old Ceph cluster running the old dumpling version 0.67.1. One of the three monitors suffered a hardware failure and I am setting up a new server to replace the third monitor running Ubuntu 22.04 LTS (all the other monitors are using the old Ubuntu 12.04 LTS).
I used ceph-deploy to deploy the cluster initially, and I can't use it since it's a very old version of ceph-deploy -- having issues with apt-key being deprecated and since ceph-deploy is no longer maintained, I can't upgrade it. And even if I can, I am not too sure if it works since the dumpling version is no longer in Ceph's official repository.
So I tried to install it manually by cloning it from git:
git clone -b dumpling https://github.com/ceph/ceph.git
But when I tried to run "git submodule update --init" or "./autogen.sh" as per the README file, I am encountering this error:
==== root@ceph-mon-04:~/ceph-dumpling/ceph# git submodule update --init Submodule 'ceph-object-corpus' (git://ceph.com/git/ceph-object-corpus.git) registered for path 'ceph-object-corpus' Submodule 'src/libs3' (git://github.com/ceph/libs3.git) registered for path 'src/libs3' Cloning into '/root/ceph-dumpling/ceph/ceph-object-corpus'... fatal: repository 'https://ceph.com/git/ceph-object-corpus.git/' not found fatal: clone of 'git://ceph.com/git/ceph-object-corpus.git' into submodule path '/root/ceph-dumpling/ceph/ceph-object-corpus' failed Failed to clone 'ceph-object-corpus'.

It seems that the repositories required for the submodules are no longer there. Anyone can advise me on the correct direction on how can I install the dumpling version of Ceph for me to add a new monitor? At the moment only 2 monitors out of 3 are up and I am worried that the cluster will be down if I lose another monitor.
$ ceph status cluster 1660b11f-1074-4f5d-aa7c-64b479397a2f health HEALTH_WARN 1 mons down, quorum 0,1 ceph-mon-01,ceph-mon-02
What approach I should take: - Continue trying the manual installation/compiling route? - Continue trying the ceph-deploy route (by fixing the apt-key deprecation issue)? - Try to install the same old OS (Ubuntu 12.04 LTS) on the new server (not too sure if I still have the ISO) and see if it works? - Try to upgrade the current cluster and then add the monitor later after upgrade? (is it risky to upgrade with HEALTH_WARN status)?
Any advice is greatly appreciated.
