Subject Possible problem with disk latency
Date Wed, 25 Feb 2015 10:19:48 GMT
Hi,
I write some question before about my problems with C* cluster. All my
environment is described here:
https://www.mail-archive.com/user@cassandra.apache.org/msg40982.html
To sum up I have thousands SSTables in one DC and much much less in second.
I write only to first DC.

Anyway after reading a lot of post/mails/google I start to think that the
only reason of above is disk problems.

My OpsCenter with some stats is following:

My iostats are like this:
https://drive.google.com/file/d/0B4N_AbBPGGwLTTZEeG1SYkF0cXc/view
(dm-XX are C* drives. dm-11 is for commitlog)

If You could be so kind and validate above and give me an answer is my disk
are real problems or not? And give me a tip what should I do with above
cluster? Maybe I have misconfiguration?

Regards
Piotrek
