jj0076 Posted August 28, 2013 Share Posted August 28, 2013 Umm, not really sure if this is the right part of the forum so mods please feel free to move post if I have screwed up.... My unraid server currently has 3 data drives and a parity and I'm now out of drive slots. I'm planning to install a 5 in 3 bay enclosure into which I plan to add a new drive as a cache drive and one of the existing drives from my array (currently mounted in the floppy drive bay!!) My question is, on moving the exisiting drive, is it simply a case of remove sata cable from motherboard and replace onto appropriate port on enclosure? Or is there something that could potentially go wrong with this approach? Link to comment
mobias1313 Posted August 28, 2013 Share Posted August 28, 2013 Assuming you are using a version 5rc then yes its as simple as just moving the drive and having a connection. If you are on a version before 5 say 4.7 you need to make sure the same port is used on the motherboard or controller for the drive when it is connected. Version 5 and up use the serial number of the drive to determine location so it makes things easier when you move drives around. Link to comment
jj0076 Posted August 28, 2013 Author Share Posted August 28, 2013 So you're saying that with v5 it doesn't even matter if it gets plugged into a different motherboard port? Link to comment
master.h Posted August 28, 2013 Share Posted August 28, 2013 That is correct. I physically re-arranged all my drives not too long ago (on 5.0RC16c) so that I could better know which drive was which in the event of a disk failure. Booted the server back up after changing, and everything came up flawlessly. Link to comment
jj0076 Posted August 29, 2013 Author Share Posted August 29, 2013 Excellent, that for the help guys, sounds like that will make life much easier!! So I can only assume that unraid is identifying the drives based on serial numbers rather than sata port number?! Cool. Link to comment
garycase Posted August 29, 2013 Share Posted August 29, 2013 Just to be clear, that ONLY applies to v5. That was stated above, but I want to be sure you noted it. If you're currently running v4.7, I'd upgrade to v5.0 before you start moving things around. But once you're on v5.0, you can freely move the drive connections to any port that's available in your system -- motherboard, add-in controller, etc. Link to comment
jj0076 Posted August 29, 2013 Author Share Posted August 29, 2013 Thanks for double checking but its all good, I'm on one of the RC versions of 5 but not sure which off the top of my head. Although I did note yesterday that V5.0 seems to have gone to a stable release now...is this worth switching to or best to stay on the RC releases? I've not had any problems and I tend to work on the logic of don't fix it if its not broken !! Edit: maybe I should change my sig so it shows details of system and version of software etc!! Thanks.
