read_ssd warnings in log

Operations

Hi,

I have a cluster running on ec2 and I noticed that it’s logging the following errors:

What do those mean and is that anything to be concerned about? Initially I did not dd the disks, but even after dd I still see those warnings.

Here’s my basic disk setup:

disks:

NAME    MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
xvda    202:0    0    10G  0 disk 
└─xvda1 202:1    0    10G  0 part /
xvdb    202:16   0 745.2G  0 disk 
xvdc    202:32   0 745.2G  0 disk

config:

namespace mydb {
        replication-factor 2
        memory-size 30G                           
        storage-engine device {     
                device /dev/xvdc   
                device /dev/xvdb
                write-block-size 128K           }
}

Thanks!

These went away after a restart of the aerospike service

Did you start with 2 disks, or did you add xvdc after prior running with only xvdb?

Is this on a community build?

@kporter,

Started with both disks from the beginning. Community build.
