USB autosuspend and external enclosure issues

Post by JCollins » 2017/12/08 18:11:34

I am having long term issues with the stability of externally attached drive enclosures, both eSATA and USB 3.0 interconnects. While I cannot find the root cause of those related to eSATA, I have read some forums discussing Ubuntu having a power saving auto-suspend feature that can interfere with attached external drives.

1. Does CentOS have similar functionality and can it be disabled for particular hardware and if so how?
2. Will there be evidence that it is the root cause of periodic disconnects where every drive in the array will generate a 'WARNING: Your hard drive is failing." message?
3. Is the USB auto-suspend feature in any way similar to any eSATA feature?

OS: CentOS 7.0, kernel: 3.10.0
eSATA enclosure multiplexer: SiI 3726
eSATA interface card demultiplexer: SiI 3132
Hard Drives: WD10EFRX
USB enclosure: ICY BOX IB-3810U3
USB enclosure multiplexer: ASMedia ASM1074L
Server motherboard USB 3.0 host: Gigabyte GA-B85-HD3 SKT 1150
