Re: glustershd coredump generated while reboot all 3 sn nodes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Hi,

- Is this stock glusterfs-3.12.3? Or do you have any patches applied on top of it?

- If it is stock, could you create a BZ and attach the core file and the /var/log/glusterfs/ logs from 3 nodes at the time of crash?

Thanks,
Ravi

Hi,

This issue happened twice recently, when glustershd do heal, it generate coredump occassinally,

I do some debug and find that sometimes afr_selfheal_unlocked_discover_on do lookup and saved the frame in function rpc_clnt_submit, when reply comes, it find the saved frame , but the address is different from the saved frame address, I think this is wrong, but I can not find a clue how this happened?

Subject: glustershd coredump generated while reboot all 3 sn nodes

 

Hi,

I find that when restart sn node sometimes, the glustershd will exit and generate coredump. It has happened twice in my env, I would like to know your opinion on this issue, thanks!

 

The glusterfs version I use is glusterfs3.12.3
