Greetings, I have google'd this and even have been waiting for 3ware support to get back to me -- however this is kind of getting out of hand and after all the research I am somewhat confused ... I have several 3ware 9550SX controllers installed under CentOS 5 with 4 each hot-swappable SATA II drives (4 drives each on 3 different servers.) Under the 3ware BIOS I set-up my RAID5 array and installed the OpSys directly to the resulting disk. I have very little experience with this controller and 'smartd' keeps telling me that I need to set /dev/sda -d 3ware,N -- but I have the array set up as 1 RAID5 hardware device that looks like 1 BIG disk to CentOS... I have tried many combinations of /dev/sda 3ware ... /dev/twa -d 3ware,0 /dev/twa -d 3ware,0/1 ... and then went back to just ... /dev/sda -d 3ware,0 /dev/sda -d 3ware,0/1 ... My main concern is that the RAID5 isn't going to work as expected -- not so much that smartd cannot seem to monitor it. I am wondering - 1) If the RAID5 controller and 3ware BIOS are doing the job as a h/w raid device - then do I need to set up smartd differently? 2) If the RAID5 array can still have individual disks seen -- even though it was set-up as a 4-disk array - why does smartd keep saying it cannot see the disks? (NOTE: I do NOT have this setup as JBOD.) Any insight would be most appreciated... -- WC (Bill) Jones -- http://youve-reached-the.endoftheinternet.org/ http://pgp.mit.edu:11371/pks/lookup?op=vindex&search=0x2A46CF06&fingerprint=on |
