Hi,

 

I'm new and testing unraid with a double usb drive, I have an issue with it:

disk are detected like this:

 

WDC_WD40_EFRX-68N32N0_RANDOM__3F4917AD758C-0:0 (sdb) 512 7814037168

WDC_WD40_EFRX-68N32N0_RANDOM__3F4917AD758C-0:1 (sdc) 512 7814037168

 

but ID in red change everytime unraid reboots, so my array can't autostart and I need to attach drive with the new ID

is there a way to fix manualy the ID of the disk? or to include a wildcard like

 

WDC_WD40_EFRX-68N32N0_RANDOM__*-0:0 (sdb) 512 7814037168

WDC_WD40_EFRX-68N32N0_RANDOM__*-0:1 (sdc) 512 7814037168

 

thanks for your help

That's the problem (one of them at least) with using USB drives.  They may not report the serial numbers of the drives correctly.  As far as I know there is no way around this short of using an external that does not operate this way or only has a single drive.  

 

Beyond that, USB drives while they do work are not recommended for other reasons.  They may not report SMART attributes correctly for determining the drive(s) health, they are prone to disconnects etc.

Ok that's a problem while I can't add more drives to this computer other than USB

I check with another USB case and this one is reporting serial and smart attributes

so I will check for a better case with UAS protocol that gives better stability to USB
