TOO SLOW data write speed and delete.. NEED HELP

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

 



Hi all,
Can someone PLEASE help me to understand why data copying (simple cp
or rsync) is SO slow in CEPH ? And delete command (\rm -rf) for removing
a small (175M) directory is taking so much of time. Because of this,
i am not able to complete evaluation of ceph using my actual workload. 

I am hereby requesting all to help me in finding out the reason for 
slow write/delete in my ceph cluster. I am really trying hard to 
complete the evaluation with actual workload but not able to copy the
data whats required for evaluation to ceph cluster bcz of slow copy.

I really appreciate any help on this.

Thanks in advance
Madhusudhan
