  1. I would am using UnRAID 4.7 and would like to migrate to UnRAID 6.8. When I bought UnRAID version 4.7, up to 20 data drives, cache, and parity drive man years ago, it included two USB flash drives. Is it possible to modify my second UnRAID 4.7 flash drive to version 6.8, and then simply power down the unRAID server and swap out the UnRAID 4.7 flash drive with the UnRAID 6.8 flash drive? Or, does the UnRAID version 4.7 to version 6.8 migration require more steps? I've also considered replacing my 6 year old system board, CPU, and memory. I have nine 2 TB data drives and one 2 TB parity drive.
  2. I am using unRAID 4.7, I haven't upgraded yet. My drive 2 was bad, as indicated when booting up the computer, but not red in the runRAID GUI, although that drive had many errors. I replaced the bad drive 2 with a new drive. The drive 2 "upgraded", then the drive 2 "rebuilt". Now, my drive 1 has 2 parity errors and the replaced drive 2 has a blinking green. I searched for the blinking green drive status and couldn't find anything yet. What does a green blinking drive status mean, and what should I do to fix it? I thought about upgrading from unRAID 4.7 to the current version of unRAID. I have a 20 drive license for version 4.7. Currently, all 10 drives are 2.0 TB. I don't know how to determine if my hardware will accept drives larger than 2.0 TB. Or, if I need to replace my 7 year old Supermicro system board, CPU, and memory with new hardware. I don't know how to determine if the older hardware will accept larger than 2.0 TB drives. I don't know the drive size limit for the current unRAID version. I'd want to increase the parity drive to the maximum drive size with the new unRAID build. If I upgrade, I'd need to buy more USB hard drives to back up all my data first.
  3. I would like to upgrade my pro version 4.7 to version 6.2. One of the first steps is to determine if the computer is capable of 64 bits. I ran the following command "grep --color lm /proc/cpuinfo", but the output is unclear to me. The "lm" string is found many times in the output. Nothing is mentioned about CPU. The string "fpu" occurs in the output. The output is attached.
  4. I am still using version 4.7 pro. I have 2 TB drives and would like to upgrade to 4 TB or 6 TB drives. I've been away from the forum for quite awhile and tried to search for the answers, but couldn't find them. I understand that version 4.7 is limited to the 2 TB drive size. What version would I need to upgrade to so I could migrate to larger drives? There was talk about having two parity drives for more redundancy. Did the two parity design occur yet? Is it possible to upgrade without backing up all the data elsewhere? I don't have any other storage that is large enough to temporarily hold about 18 TB of data.
  5. I searched and found some posts about 4 TB drives, but I did not find anyone using them with unRAID yet. Are 4 TB drives compatible with unRAID version 4.7? If so, which brand/model 4 TB drive is recommended? Does the preclear script work with the 4 TB drives? I would like to change out my 2 TB parity green drive with a 4 TB, then later change out 2 TB green drives with 4 TB drives as the 2 TB drives eventually fail. Dave
  6. I purchased two pre-configured UnRAID Pro USB jump drives several years ago. I reformatted one of the two pre-configured jump drives. I then went through the process to install the software and make the USB jump drive bootable. I assume I need to activate the unRAID Pro software somehow. The pre-configured unRAID Pro jump drive must be registered. How do I get the key and apply it to the USB jump drive? Dave
  7. I am considering building up an unRAID server with my unRAID USB jump drive for my work location, then later, my employer will buy their own unRAID USB jump drive. Can the unRAID server be powered down, the two unRAID jump drives be swapped, then the unRAID server be powered up? Is it that simple, without loosing any drives or any data? Dave
  8. I'm rebuilding my unRAID server version 4.7 and preclearing all the drives, one by one, that are formatted for Windows, without the AF pin 7-8 jumper, version 1.8, and the -A option. Is there any need to preclear with version 1.9 instead of the preclear version 1.8? I just started the process last night, so I could update the preclear_disk.sh script and start over. Dave
  9. It is attached to the first post in this thread: http://lime-technology.com/forum/index.php?topic=2817.0 You must be logged in to see the attachment. Joe L. The preclear script download used to work that way for me. Months ago, when I was not logged in, I did not see the download. I then I logged in and saw the download. Now, the download never displays, even though I am logged in. I think that part of the web site is not working anymore. So, the download is never visible for me. I am attaching a screenshot, so you can see there is no visible download when I am logged in. Dave preclear-script.zip
  10. I have an older preclear_disk.sh script with verison 4.5.6. I am going to upgrade to 4.7 and need to download an updated preclear_disk.sh script. I am logged into the forum, but I haven't been able to find the download anywhere, in utilities, or anywhere else. Dave
  11. Thanks for the responses. Will the Seagate tool work with Western Digital WD20EADS and WD20EARS drives? Could you post a link to the utility? Dave
  12. I am rebuilding my unRAID server, replacing a Gigabyte GA-EX580UD5 system board with a Supermicro MBD-X8SIL-F-O. HPA cannot be disabled in the Gigabyte system board. I moved all my data off my unRAID server to Windows formatted drives. Eventually all my drives are being removed from the old unRAID server and formatted with Windows, using a computer that does not have a Gigabyte system board. If HPA existed on any of the drives, does the Windows system formatting remove the HPA? I was planning on running the preclear_disk.sh with the -A option when rebuilding the new Supermicro unRAID server for MBR-4K aligned drives. The old runRAID server was using version 4.5.6. I plan to build the new unRAID server with 4.7. My 2 TB WD Advanced Format drives all had the jumper installed. My plan is to not use the jumper and use the -A switch during the preclearing process. The MBR-4K aligned drives will not work in unRAID versions below version 4.7. It has been mentioned before that old AF drives should have the jumpers left in and be used as MBR-4K non-aligned drives. One advantage to leaving the drives MBR-4K non-aligned is that you could go back to the older unRAID versions. Is there an upside to using the -A option in the preclearing process to have MBR-4K aligned drives? If there isn't an upside to using the MBR-4K aligned drives, then I'm not sure why anyone would switch to using MBR-4K aligned drives, even with new drives. Maybe there is a performance reason, or some other reason. Since I'm going through the whole rebuild process, I plan to build all the drives as MBR-4K aligned drives, one drive at a time, as I move all the data back from the Windows formatted drives over the next several weeks.

  13. If a Norco case is used, then one thing to consider is connecting the hard drives to the on board ports and the controller ports, making them in groups of four. For example, if a system board has 6 sata ports, then one cable connects four bays to four of the six on board sata ports. If a second cable is used for the remaining two on board ports, then two bays will be unusable, unless you have a sata controller card with two sata connections. The Supermicro controller card works out with no wasted ports, since it has two mini SAS connections, each with 4 ports. I am still considering the Norco 4224, but I'm afraid that the drives will run hotter than they do in my full tower using Thermaltake iCage A2309 HDD Module with 12cm Blue LED Fan 3 in 3 drive cages because the drive density is much higher in the Norco cases. Although the Norco cases look much better than my full tower with the 3 in 3 drive cages. Dave
  14. I am rebuilding my unRAID server. I started with a Gigabyte i-7 950 3.06 quad core with 3 gigs of 1600 meg ram. The rebuild is to get away from the Gigabyte HPA, which cannot be disabled on my system board. The new unRAID server will consist of: Supermicro MBD-X8SIL-F-O system board Kingston 4GB (2 x 2GB) 240-Pin DDR3 SDRAM ECC Unbuffered DDR3 1333 Server Memory Model KVR1333D3E9SK2/4G Intel Core i3-540 Clarkdale 3.06GHz 4MB L3 Cache LGA 1156 73W Dual-Core Desktop Processor ZALMAN CNPS9900MAX-B 135mm Long life bearing CPU Cooler Blue LED SUPERMICRO AOC-SASLP-MV8 PCI Express x4 Low Profile SAS SAS RAID Controller 3ware CBL-SFF8087OCF-05M 1 unit of 0.5m Multi-lane Internal (SFF-8087) Serial ATA breakout cable, forward The system will be slower, but my understanding is that the unRAID server would not benefit much from the fast quad and faster memory anyway. I will be using the same Western Digital 2.0 TB WD20EADS drives. Am I assuming correctly that the unRAID server's throughput would not be effected much by the differences in processors or memory. Is there any benefit to going above 4 gigs RAM? Is there any benefit to using a quad-core instead of a dual-core? I have been moving all my data off the unRAID server to Windows formatted 2.0 TB drives, one drive at a time. I am planning on upgrading from unRAID 4.5.6 to version 4.7 for the new build. I will be adding one drive at a time back to the new unRAID server. When the drives are added back to the unRAID server, they will need to be precleared again. Does it make sense to not use the pin 7-8 jumpers and preclear with the -A option? I assume all future unRAID versions will be supporting the Advanced Format 2.0 TB drives without the pins 7-8 jumpers in the future. Dave
  15. I need to know which SAS to sata cables are needed for the SuperMicro AOC-SASLP-MV8 - 8 Port SATA II PCIe x4 (requires SAS cables). There are two links for SAS to Sata cables, both for the Norco cases. I want to connect the two SFF-8087 mini-SAS connectors to 8 sata drives, not using a Norco case. The Newegg site does not list which cable are needed either http://www.newegg.com/Product/Product.aspx?Item=N82E16816101358 Dave
