Jowi, yes i thought of you. Well, 4 out of 6 drives were working. I think 4 on one split out cable was too much. Anyway, i will re run the 2 failed disks.

Johnm, I run with 4 MB of Ram on a ATOM based mainbord: Supermicro X7SPA-HF I posted the errors i received here: http://lime-technology.com/forum/index.php?topic=4068.msg191817#msg191817 I though of a issue with pre-clear, but there i think my memory was indeed the issue seen in the error in the above mentioned thread. So it was not wise to start with 6 discs i guess. On the bandwidth. It is a 16 port SAS non raid controller with PCI-E 4x From the Marvel Site: The first product in Marvell’s SAS controller portfolio is the Marvell 88SE6440 host controller, supporting four SAS/SATA ports. The 88SE6440 offers 4-lane PCI-Express connectivity to the host system for high throughput in bandwidth-hungry applications From their PDF: 88SE6440 PCIe x4 to 4 SAS/SATA 3Gb/s Ports RAID Controller From the sata wiki SATA revision 2.0 (SATA 3 Gbit/s)Second generation SATA interfaces running at 3.0 Gbit/s shipped in high volume by 2010, and were prevalent in all[citation needed] SATA disk drives and most PC and server chipsets. With a native transfer rate of 3.0 Gbit/s, and taking 8b/10b encoding into account, the maximum uncoded transfer rate is 2.4 Gbit/s (300 MB/s). So with this LSI SAS expander behind the Marvel chip there is never more than 4 times 300 Mbyte/sec This must be somehow shared between the 16 ports, i assume every 4 usable sata interfaces share one Marvel Sata interface as 4 x 4 = 16. Than each physical interface can use maximal 300/4 = 75 Mbyte/sec I saw 2 discs doing around 150 Mbyte/sec in the pre-clear, and 2 rather slow ones at the start which failed after like 1 hour and some minutes.

After some more checking on the web i think that it has a Marvell 88se6440 for the connection to the PCI-E 4x slot. It than outputs 4 SAS/SATA channels of 300 (?) Mbyte/sec into a LSI SASX28 which seems to be a port muliplier. http://www.marvell.com/products/storage/Serial_Attached_SCSI_SAS_Storage_Controller/release/742/ So i fear every SFF-8087 connector (behind the SASX28) which fans out into 4 SATA cables is in fact sharing 300 (?) Mbyte/sec from one of the Marvel 'channels' If this info is correct, i am not surprised it stopped working for half the discs as i had 4 times a hdd connected that does >150 MB/sec on the outer sectors. 2 were working, 2 not... (or better said: slow at start, stopped after 1 hour 40 minutes) Have to try out this: Not do connect 4 drives on one fan-out cable, but distribute across the 4 fan-out cables to utilise all the 4 channels. One question left: Will this work with parity calculation where every disk is read (i assume starting at the lowest sector for all disks at once and than work its way up)

I tried to preclear 6 drives at once: system: System: Supermicro - X7SPA-HF CPU: Intel® AtomTM CPU D525 @ 1.80GHz - 1.8 GHz Cache: 48 kB Memory: 4 GB - 800 MHz Network: 1000Mb/s - Full Duplex 5.0-rc5 drive on mainbord: 1) Hitachi_HDS724040ALE640_PK1311PAG4DNJS (sda) 3907018584 drives on ARC1300-16: 2) Hitachi_HDS724040ALE640_PK1311PAG4VJ7S (sdd) 3907018584 3) Hitachi_HDS724040ALE640_PK2311PAG4R9WM (sde) 3907018584 4) Hitachi_HDS724040ALE640_PK1311PAG4VMSS (sdf) 3907018584 5) Hitachi_HDS724040ALE640_PK2311PAG4SX0M (sdg) 3907018584 6) Hitachi_HDT725032VLA380_VFA200R2CL7TPA (sdh) 312571224 6) worked ok and finsihed ok (320 GB) 1) still running 3) still running 4) still running 2) stopped at 1:40 hours in first step 5) stopped at 1:40 hours in first step I added a part of the syslog with the errors, seems something crashed.

The 2. 14% ones seem stuck, their run time counter does not increase anymore.

Was i simply out of memorey there ? I did run a pre-clear on 6 drives at once. An 320 GB succeeded, 3 x a 4 TB disk is still running, and 2 are stuck. After this error the syslog is filled with these: Jul 22 01:49:40 Tower kernel: sas: command 0xc0f20f00, task 0xd3496640, not at initiator: BLK_EH_RESET_TIMER Jul 22 01:49:40 Tower kernel: sas: command 0xdd93bc00, task 0xc75472c0, not at initiator: BLK_EH_RESET_TIMER Jul 22 01:50:11 Tower kernel: sas: command 0xc0f20f00, task 0xd3496640, not at initiator: BLK_EH_RESET_TIMER Jul 22 01:50:11 Tower kernel: sas: command 0xdd93bc00, task 0xc75472c0, not at initiator: BLK_EH_RESET_TIMER This last error is reported on this site with issues with 3 TB drives also: http://lime-technology.com/forum/index.php?topic=15810.0 This specific error perhaps comes up in google search frequently like this one: http://www.spinics.net/lists/linux-ide/msg42602.html Perhaps me starting 4 times a 4 TB hitachi 7K4000 was too much data for the Areca, or simply too much for the system, as on the mainboard an hitachi 320 Gb and a 4TB were also preclearing. I will wait for the 3 curently running ones (1 on mainboard and 2 on the areca) and reboot and retry the failed 2. (one on the areca and one on the mainbord than to compare)

In the meanwhile i received my components, and now all seems to work. I have precleared 1 TB via the mainbord, and now running 5 drive pre-clear (1 via mainbord, 2- 4 via the ARC-1300) Strange effect though: 1) 76% - 36 degrees 2) 14% - 40 degrees 3) 66% - 41 degrees 4) 65% - 40 degrees 5) 14% - 37 degrees So i seem to have 2 slow ones, and 2 faster ones. These drives are all connecte via an sff8087 to 4 sata cabel. Perhaps config issueon the areca ?

i looked up all the manufacturers specs for my hdd's: Hitachi 7K4000 2,0 Hitachi HDT721010SLA360 1,87 Samsung HD103UJ 2,4 Samsung HD145UI 2,0 seagate ST2000DL003 2,1 All values for Amperage at 12 volts during startup This would be around 47 amps at startup for the 12 Volt.

Is a seasonic Platinum powersupply advised nowdays ? http://www.seasonicusa.com/Platinum_Series.htm I will have 22 hdd's i think, most of them 7200 RPM. Is the 860 enough (71 AMP) or better the 1000 (83 AMP) The drives: 7200 RPM Hitachi 7K4000 (4TB) (5) Hitachi HDT721010SLA360 (1TB) (5) Samsung HD103UJ (2) green: Seagate ST2000DL003 (2TB) (3) Samsung HD145UI (1.5 TB) (5) Growth/replacement most likely hitachi 5K3000 / 7K4000 edit: only 22, no more sata ports edit 2: 'only' 11 Sata and 8 molex connectors.

Dhcp did not work, so i did put in a ip address manually. Is there a text based gui ? I should read more info first i guess. The description of the http based gui seemed clear, so i hoped to use that

I could not do much during my tests unfortunately. I have issues getting the LAN to work. I configured the eth0 with fixed ip, but it comes up in 10 mbps half duplex. I cannot ping the default gateway (i am sure on the ip adressing) How do i set the ethernet config to 1000 full fixed ? I assume if i get the ip connection working i can use a other device to browse to the web interface of it and have a more manageble interface (for me as a non linux user at least)

Hello all, i am new to this forum. I am thinking of setting up a unraid server. For sata ports i have a Areca ARC-1300ix-16 available. http://www.areca.com.tw/products/sasnoneraid3g.htm I did download a free version of unraid (unRAID Server 5.0-rc5 AiO) and created abootable usb flash disk (sandisk 8 GB) For test purpose i used my main PC which is a Asus P6T WS pro mainbord with i7 and 12 GB ram. X58 / ICH10R - 2 x Realtek® 8111C PCIe Dual Gigabit LAN controllers and only that areca controller with one 320 GB hitachi disk attached. It seems to start ok, end i end up on the linux command prompt. If i browse through the syslog i see the following entrys: Jul 6 18:37:24 Tower kernel: sas: Enter sas_scsi_recover_host Jul 6 18:37:24 Tower kernel: ata7: sas eh calling libata port error handler Jul 6 18:37:24 Tower kernel: sas: sas_ata_hard_reset: Found ATA device.

If this controller really works i intend to buy a supermicro ATOM mainbord http://www.supermicro.com/products/motherboard/ATOM/ICH9/X7SPA-HF-D525.cfm I have also orginal Cooler Master CM Stacker case, and a coolermaster 1000 watt power supply spare for this. I can than go for 3 times a 5in3 module and so go to 15 drives without to much cost in the hardware outside the new 3 TB Hdd´s Thanks for any help. syslog.txt
