Poor performance on RAID-10 AFTER disk rebuild on IRST

JMeurisse Community Member

Hi all,

 

I have been using a RAID-10 array since a couple of months and it worked nicely (Read speed  was about 168MB/s) until recently.

 

When I switched on the computer, the array status was REBUILDING. It took about 24 hours to get it done and got back the "NORMAL" status. However, despite the fact all seems to be OK from the Intel monitoring dashboard, the array performances are now dramatically poor (average READ speed of the array is 1.6MB/s) and it is practically unusable although all my data are available.

 

1) How can I troubleshoot the cause of the issue since all seems to be OK from the Intel monitoring dashboard? Are there any logs somewhere?

2) Do you think this is a hardware or software issue?

3) Is it possible to "break" the RAID to test the speed of my disks individually, but without lossing my data?

 

Thanks a lot in advance for your help!
