Yeah, those issues do get discussed at times on the Linux RAID list. |
| 26 |
I've asked questions about it and been told that Linux software RAID |
| 27 |
depends totally on what the driver tells it and nothing seems to be |
| 28 |
don (as best I can tell) based on any fixed time. That's more of a |
| 29 |
hardware controller issue. I was told that if the drive by itself |
| 30 |
doesn't fail at the system level when it's spinning up, then it won't |
| 31 |
fail at the RAID level either. However what it does if it has a |
| 32 |
hardware error is a bit beyond me at this point. My intention is to |
| 33 |
try and get better with smartd so that the drive is continually |
| 34 |
monitored and see if I can get ahead of a failure with that. |
