It indicates your file-system on /dev/md2 is corrupted and needs repair. To fix, see the Wkii page here: http://lime-technology.com/wiki/index.php?title=Check_Disk_Filesystems unRAID is built on top of Slackware (or rather a stripped down Slackware distribution, with enough left for unRAID to act as a network-file-server.) The commands available are most all those available under Linux. To re-scan the hardware you would need to re-start the "udev" daemon process. That will create the proper device entries under /dev. This has nothing to do with unRAID, but linux. I know "udev" will create the entries for USB disk drives when they are plugged in, I have no experience on how it works with SATA disks. A lot would have to do with the individual SATA controller driver I would guess and how it is coded for the chipset on your hardware. Your hardware might automatically trigger a re-scan, and the devices might automatically be created. If not, you could type: /etc/rc.d/rc.udev restart Again, this is not specific to unRAID, but to Slackware Linux. However... even if/when "udev" adds /dev entries, you may not see them in the possible list of drives you will see on the unRAID "Devices" management page. (It all depends on if the list is created once, when the management utility process/web-server is started, or dynamically when the "Devices" page is invoked. I might be wrong, but I think it is the former.) I suppose you could always figure out how to kill and re-start it, but from your questions, it appears as if that might be very advanced stuff for your level of experience. The Wiki, especially the User-Contributed section, (see my signature link) is your best place for answers to most questions, although you are one of the first to ask about hot-plug support. Support of that kind is fairly new to Linux in general, and I'll bet unRAID was not coded for it as it was originally developed for IDE based hardware, and it was sure not Hot-Plug compatible. Joe L.
