grandprix Posted July 29, 2011 Share Posted July 29, 2011 Currently have a 7 drive setup (5 data, 1 parity and 1 cache-which has yet to be enabled/setup in devices). I just finished pre-clearing an 8th drive (data), which went fine returning zero errors, however, oddly it is not showing up as an available device when attempting to add it to the array. It shows just fine under myMain as well as unRAID's menu under partitioned drives not in array: /dev/sdi1 scsi-SATA_Hitachi_HDS5C30_ML0220F30Txxxx But, is not available in the drop down in the devices menu, let alone a format button showing. One thing I just noticed was, the model. I have a Hitachi 5K3000 already in the array working just fine, has been for at least two months. It shows as this: Hitachi_HDS5C302_ML0220F30Hxxxx Notice the addition of the "2" in the model number (i.e. HDS5C302 vice the one I'm trying to add: HDS5C30) The model number on the drive itself reads fully: HDS5C3020ALA632 (0F12117) Firmware: 580 Here is the result of a: preclear_disk.sh -t /dev/sdi is as follows ################################################################## 1.9 smartctl may not be able to run on /dev/sdi with the -d ata option. however this should not affect the clearing of a disk. smartctl exit status = 4 smartctl 5.39.1 2010-01-28 r3054 [i486-slackware-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net === START OF INFORMATION SECTION === Device Model: Hitachi HDS5C3020ALA632 Serial Number: ML0220F30Txxxx Firmware Version: ML6OA580 User Capacity: 2,000,398,934,016 bytes Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 8 ATA Standard is: ATA-8-ACS revision 4 Local Time is: Fri Jul 29 15:42:21 2011 EDT SMART support is: Available - device has SMART capability.

Joe L. Posted July 30, 2011 Share Posted July 30, 2011 preclear_disk.sh is up to version 1.12, your version 1.9 is a bit old. Give the newer version a try to get the smartctl reports working. Link to comment
grandprix Posted July 30, 2011 Author Share Posted July 30, 2011 Well, I performed a proper shutdown and upon reboot I decided to play a visit to my BIOS. Seems I still had the IDE channels on the mobo (as well as the serial ports) still enabled. Without thinking, by disabling the IDE channels (which I thought I had already done upon build up -- pre-population of the server) it changed the device assignments (i.e. sdb, sdc, sdi, etc.). Soooo... I'm not too certain how unRAID works precisely, though I have a feeling that the parity drive stores the XOR information of the data drives according to device, in which case, I'm sure if I do a parity check, it will fail miserably. Or am I fine? I'll go with updating preclear as well as finding what else I may be behind in (besides the actual unraid version, I dont think version 5 is "stable" yet right?). About the smartctl reports Joe, is that an add on or ? I'll search of course right after I "post" this, though any direction is greatly appreciated. Link to comment
grandprix Posted July 30, 2011 Author Share Posted July 30, 2011 Actually, I think I'll wait to see what those more knowledgeable say concerning the device identification change.. I really have a feeling my parity may be worthless right now after them being changed around due to disabling the mobo's IDE channels. Link to comment

In fact, the assignments are given as disks initialize and the OS detects their presence. The disk assignments (sda, sdb, sdc, etc. ) can change from one boot to the next. It is perfectly normal. For unRAID to show the disk in its drop-down list, it must be a /dev/sdX or /dev/hdX device and have entries in /dev/disk/by-id and /dev/diskby-path and /dev/disk/by-uuid Those entries are made by the "udev" subsystem when your disk controller tells the OS the disk is present.

grandprix Posted July 30, 2011 Author Share Posted July 30, 2011 Alright, thank you Joe, puts my mind at ease then. Now to tackle the smartctl reports situation. I've downloaded and placed on the flash drive your newest version of preclear. I'll make it a point to pay closer attention to new release versions from here on out. A search for smartctl reports isn't helping much just yet, though I am only on the 2nd page of search results. Any leads? Again, tahnk you Joe. Link to comment
