-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi, I was wondering if there are any procedures for rebooting a node? Presumably when a node is rebooted, Ceph will lose contact with the OSDs and begin moving data around. I’ve not actually had to reboot a node of my cluster yet, but may need to do so in the near future. Does Ceph handle reboots gracefully or will it immediately begin moving data around? I ask because due to the hardware we’re running, we have a fair few OSDs per node (between 32-40, I know this isn’t ideal). We recently had a node die on us briefly and it took about 2 hours to get back to HEALTH_OK once the node was back online after being down for around 15 minutes. This is with about 16TB of data (of 588TB total), so I’m worried about how a reboot (or another node failure) will affect us when we have more data on there.
