Servers: 6 (include 7osds) total 42osdsl OS: Centos7 Ceph: 10.2.5 Hi, everyone The cluster is used for VM image storage and object storage. And I have a bucket which has more than 20 million objects. Now, I have a problem that cluster blocks operation. Suddenly cluster blocked operations, then VMs can't read disk. After a few hours, osd.1 was down. There is no disk fail messages in dmesg. And no error is in smartctl -a /dev/sde. I tried to wake up osd.1, but osd.1 is down soon. Just after re-waking up osd.1, VM can access to the disk. But osd.1 always uses 100% CPU, then cluster marked osd.1 down and the osd was dead by suicide timeout. I found that the osdmap epoch of osd.1 is different from other one. So I think osd.1 was dead. Question. (1) Why does the epoch of osd.1 differ from other osds ones ? I checked all osds oldest_map and newest_map by ~ceph daemon osd.X status~ All osd's ecpoch are same number except osd.1 (2) Why does osd.1 use CPU full? After the cluster marked osd.1 down, osd.1 keeps up busy. When I execute "ceph tell osd.1 injectargs --debug-ms 5/1", osd.1 doesn't answer. Thank you. -- Makito

Hello, what you see is an stracktrace, so the OSD is hitting an unexpected state (Otherwise there would be an error handler). The crash happens, when the osd wants to read from pipe when processing heartbeat. To me it sounds like a networking issue. I see the other OSD an that host are healthy, to I would bet there is an issue with tcp port that this particular osd daemon used. Try 'netstat -tulpen' or so to check. If there a firewall between the host that might cut something off? rgds, j. On 02.02.20 04:08, Makito Nishimiya wrote:

The crash happens, when the osd wants to read from pipe when processing heartbeat. To me it sounds like a networking issue.

I think I am with Wido on this one, if you get one or a few PGs so full of metadata or weird stuff that it takes longer than suicide_timeout to handle it, then it will be like this. At start it tries to complete whatever operation was in queue (like scrubs, recovery, something) and it just gets stuck doing that instead of answering heartbeats or finishing operations requested by other OSDs or clients, and gets ejected from the cluster. If it is anything like what we see on our jewel cluster, you can move these PGs around with impact to clients but you can't "fix" them without doing deep changes like moving from leveldb to rocksdb (if filestore), splitting PGs and sharding buckets if it is RGW metadata that causes these huge indexes to end up on a single OSD. You sort of need to figure out what the root cause is and aim to fix that part. -- May the most significant bit of your life be positive.

What do you guys Think about Ceph osd Set noout/Down And See if the osd will become healthy? Another idea which is in my mind is to remove the sayed osd from the Cluster... As long as the other osds on the same node dont have an issue i guess the disk has a Problem... Just my 2 Cents - Mehmet Am 3.

Hello, what you see is an stracktrace, so the OSD is hitting an unexpected state (Otherwise there would be an error handler). The crash happens, when the osd wants to read from pipe when

heartbeat. To me it sounds like a networking issue. I see the other OSD an that host are healthy, to I would bet there is

issue with tcp port that this particular osd daemon used.

Hi, everyone. The problem was solved. A PG's epoch of active osds was dfferent from one of acting osds. When I removed head and TEMP directory of the PG from active osds, blocked request vanished. Thanks to your kindness. 2020年2月6日(木) 4:19 <ceph(a)elchaka.de>de>:

Hello, what you see is an stracktrace, so the OSD is hitting an unexpected state (Otherwise there would be an error handler). The crash happens, when the osd wants to read from pipe when

processing

heartbeat. To me it sounds like a networking issue. I see the other OSD an that host are healthy, to I would bet there is

issue with tcp port that this particular osd daemon used.
