Ceph Cluster - loss of one host caused storage to go offline

Hi There,

We've got a 5-node ceph cluster with 10gbps networking. All hosts have 3 x HDDs in them for "slow" storage, and all hosts but 3 have SSDs in them for fast storage.

  • Hosts 1,2,3,4,5 all have 3 x HDDs in them - we used this for anything that needs "Slow" storage.
  • Hosts 1,2,4,5 all have 1.2 TB enterprise SSDs in them. Only one SSD per host.

There are two replicated rules - one for HDDs and one for SSDs. We then have pools added that use either rule depending on what kind of storage we need.

Recently, we had to to take a node #2 offline for maintenance. When we did this, all hosts lost access to the SSD backed pools. HDD pools were still working. All the VMs/CTs on the pool were totally locked up. I couldn't display the contents of the storage from the web interface (but the HDD backed pools were working great).

If it matters, the person in charge of the maintenance forgot to set noout.

Why did this happen? It was my understanding that our cluster can tolerate a 'host' level failure - our size/min is set to 3/2.

Let me know if you need anymore info to help figure this out.

This depends on the crush rules and how the pool is configured. Run a ceph osd df tree, ceph osd dump, ceph osd crush rule dump to see if the pool and the rules are in check.

Output of commands below. the ceph osd crush rule dump shows 3 rules total, but the first (default one that was "included" when ceph was set up) isn't in use anymore.

Have you tried to up the min-size for your pools? I think the issue is that you have min-size set to 1, meaning only 1 copy of the data will be saved. Had the same issue some time ago with a test-pool and as soon as I set the min-size to 2, it wasn't an issue anymore.

That is not my problem. I have size 3 min 2.


Code:
pool 9 'ceph_hdd' replicated size 3 min_size 2 crush_rule 1 object_hash rjenkins pg_num 512 pgp_num 512 last_change 10523 flags hashpspool stripe_width 0 application rbd
        removed_snaps [1~3,9~4,f~114,124~14]
pool 20 'ceph_pci_SSD' replicated size 3 min_size 2 crush_rule 2 object_hash rjenkins pg_num 256 pgp_num 256 last_change 10319 flags hashpspool stripe_width 0 application rbd
        removed_snaps [1~3]

Sorry I misread! To me it looks like a problem with the crush rule you are using... Did you try to use the default one?

Proxmox VE 5.4 and Ceph Luminous are EoL. Please upgrade, we may just hunt something that has been fixed already.
https://pve.proxmox.com/wiki/Upgrade_from_5.x_to_6.0
10 ssd 1.09589 1.00000 1.10TiB 629GiB 493GiB 56.09 1.00 200 osd.10
200 PGs is a bit to much, the optimal target is around 100 PGs per OSD. With Ceph Nautilus the existing pool can be adjusted.

pg_temp 9.0 [17,4,0]
pg_temp 9.1 [3,2,18]
pg_temp 9.2 [18,3,2]
These temp PGs shouldn't exist.

But none if should affect the ability while one node / OSD is down. Best check in the ceph logs what happend during that time.
