Random HDD, system issues

[Fuggin]

Hello...I am experience just random drive disappearance and drive smart faults. It's just confusing me.

 

I have 16 drives total, parity, cache, the rest are data. I have a motherboard with 6 SATA ports (Parity-sdf), 2-SATA port card (sdg-sdh), an 8-port SAS expander card (sdi-sdo, cache).

 

Sometimes when I go on the dashboard, the drives will disappear. I will have to reboot the system for them to reappear. I wonder if it is just the nature of my components because I am using the combination of the motherboard, 2-port car, and the expander card that is causing inconsistent operation. Should I just purchase another expander card and move all my drives onto it?

 

Please advise.

What power supply are you using?    I have seen random drive disappearances when a system is under-powered for the number of drives attached.

I agree,  the first thing i would check is the power supply

And post a syslog

Did a hard drive drop during that syslog (Feb 18 21:14 - Feb 20 18:10)?

 

Nothing is showing in the syslog indicating any failure at all?  Wait until a drive drops out and then post another syslog before you reboot the server.

 

That power supply  should have no problems with the number of drives.
