August 4, 200718 yr I'm running a system I built using a starter set (Intel mobo, processor, 2 pci cards for the added drives) from Tom using 12 IDE drives. I have the Stacker case and use Icydocks to connect the drives. I'm on 4.1 and when I reboot the system, the 4 drives attached to the motherboard all come up missing. I have to go into the settings page, reassign them (they all appear in the drop down), and do a restore configuration and parity sync. I have not touched the BIOS since getting the system with version 3.0 and did not see this behavior with any upgrade through 4.0. Attached is my syslog. Any help to get the drives found on startup would be appreciated.
August 4, 200718 yr Your syslog looks fine to me. There appears to be an issue with upgrading to 4.1, concerning a change in hardware detection/identification, and that appears to be what has happened to you and another user. The first 4 drives were probably (I'm guessing) hda through hdd, and have now been assigned a SATA-like driver, and given ID's sda through sdd. UnRAID did not recognize them, but you did when you reassigned them to the correct disk. You then clicked the button to mark them as New, and started the array. It recognized a Reiser file system on all but the Parity drive, so after you finish a Parity Sync, you should be fine. When you ask for 'Any help to get the drives found on startup', are you saying you tried a second time and they weren't found again? On my system, the hardware detection/identification was different, but not as radical as yours or the other user. Mine just swapped the flash (sdg to sde) with one of my drives (sde to sdg), but recognized the serial numbers (I guess), and assigned all of them to the correct disk.
August 4, 200718 yr Author Yes. Anytime I reboot the system, the drives go missing again. As you said, unRaid thinks that they are SCSI/SATA and I have to reassign them again.
August 8, 200718 yr Author I figured it out. Somehow my Super.Dat got messed up. I replaced it with an old backup copy I had and the drives came up like they should.
August 9, 200718 yr Well... I have the same problem. Just updated to 4.1 and one of my disks went missing. It was listed in the devices section and is now recreating the "missing disk" from parity. Sure would like to figure out what to do here....
August 10, 200718 yr Author If it's the same problem that I had and you still have a copy of Super.Dat from your 4.0 setup, just copy it over on the flash. If you don't have an old copy, I think it will rebuild it if you delete it, but I am not positive.
August 12, 200718 yr Well I don't have a backup... Actually I'm not very Linux savvy so I'm not even sure how to make a backup or where I would find the file to back up... It did not recreate my missing disk... In fact it tells me that it is unformated and wants to format it. I'm going to try dropping back to 4.0 to see what happens. I hope that it brings things back to the way they were but I'm not very confident... Any advice would be appreciated! Chris
August 12, 200718 yr It did not recreate my missing disk... In fact it tells me that it is unformated and wants to format it. I'm going to try dropping back to 4.0 to see what happens. Chris, Search the site, but if you want to save the data on the disk (assuming you formatted it under unRAID once before), I believe you can force it to accept it and simply rebuild the parity. I suspect dropping back to 4.0 will not change your situation. Bill
August 12, 200718 yr Ok, so dropping back to 4.0 solved my problem. My disk is back up with no data loss. Now the question becomes should I backup the necessary files and give 4.1 another try or should I wait to see if this issue gets fixed.... If I were to try 4.1 again what do I need to backup and how do I do it?
August 13, 200718 yr Author You can backup everything. When upgrading, the only things that change are Bzimage and Bzroot.
