Hello good people of the Unraid forums!

 

Absolute noob on his first server setup here. Ive been using unraid for a couple of weeks now, it has

99% of the time been a lovely experience.

 

I am running UNRAID on a IBM X3550 M4, that has a ServeRAID M5110 card in it set in IT mode. (i will probably replace it with some sort of HBA board when I can find one I can afford)

 

The server currently has 1x 1TB Seagate disk in it, as well as 1x 250GB Samsung SSD for cache. And here is the issue:

Whenever I reboot the server, the 1TB disk is not always recognized. I also see that my UNRAID logs get filled up with the following line:

May  7 20:05:17 Unraid emhttpd: device /dev/sdc problem getting id
May  7 20:05:18 Unraid emhttpd: device /dev/sdc problem getting id
May  7 20:05:19 Unraid emhttpd: device /dev/sdc problem getting id
May  7 20:05:21 Unraid emhttpd: device /dev/sdc problem getting id
May  7 20:05:22 Unraid emhttpd: device /dev/sdc problem getting id
May  7 20:05:23 Unraid emhttpd: device /dev/sdc problem getting id
May  7 20:05:24 Unraid emhttpd: device /dev/sdc problem getting id

I have to pull out the disk from the server, re-insert it, then do the "new config" option in the Tools-tab to make it re-appear.

I do not know why this is necessary and would much prefer not to. Does anyone know what is wrong?

 

Thanks in advance!

RAID controllers are not recommended anyway, use the onbaord SATA ports (or one of the recommend controllers).
