Disk Issues

I have 40 disks attached to each of my data nodes. In one of my data node, I see few disks are unreadable:

[root@node8.XXXX.XXXXX ~]# ls -l /disk8
ls: reading directory /disk8: Input/output error
total 0
[root@node8.XXXX.XXXX ~]#
[root@node8.XXXX.XXXXX ~]# ls -l /disk23
ls: reading directory /disk8: Input/output error
total 0
[root@node8.XXXX.XXXX ~]#

I thought ambari should automatically detect this and report me as "DataNode Unmounted Data Dir", but looks like thats not the case.

here are my questions ?


Should I work on replacing these disks ?

If so, why Ambari did not alert me on this ?


Thanks

Kumar
