Re: Fio randwrite does not work on Centos 7.2 VM

[Somnath Roy <Somnath.Roy@xxxxxxxxxxx>]

There should be a line in the log specifying which assert is failing , post that along with say 10 lines from top of that..

 

Thanks & Regards

Subject: [ceph-users] Fio randwrite does not work on Centos 7.2 VM

 

Hi All,

 

Has anyone faced a similar issue? I do not have a problem with random read, sequential read, and sequential writes though. Everytime I try running fio for random writes, one osd in the cluster crashes. Here is the what I see at the tail of the log:
