Hello, I have been running unRaid 5.0 for quite some time now have 13 various drives in the system. Yesterday in order to expand space I decided to replace disk1 (1.5B) by a brand new 4TB Hitachi drive. Here is what I did: Ran a parity check and rebuild Precleared new 4TB Replaced disk1 (1.5TB) by the 4TB one Rebooted and assigned the new drive Data rebuild then started for disk1 with an estimated time to completion of 1 day. Following moring I checked the status and ETA jumped to 400 days. I then looked at dmesg and it was full of read error messages from disk12 (another 4TB that was added to the system many months ago). md: disk12 read error, sector=586096 md: disk12 read error, sector=586104 ata7.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 ata7.00: edma_err_cause=00000084 pp_flags=00000001, dev error, EDMA self-disable ata7.00: failed command: READ DMA ata7.00: cmd c8/00:00:c0:f1:08/00:00:00:00:00/e0 tag 0 dma 131072 in res 51/40:00:c0:f1:08/40:04:00:00:00/e0 Emask 0x9 (media error) ata7.00: status: { DRDY ERR } ata7.00: error: { UNC } ata7: hard resetting link ata7: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata7.00: configured for UDMA/133 sd 6:0:0:0: [sdh] Unhandled sense code sd 6:0:0:0: [sdh] Result: hostbyte=0x00 driverbyte=0x08 sd 6:0:0:0: [sdh] Sense Key : 0x3 [current] [descriptor] Descriptor sense data with sense descriptors (in hex): 72 03 11 04 00 00 00 0c 00 0a 80 00 00 00 00 00 00 08 f1 c0 sd 6:0:0:0: [sdh] ASC=0x11 ASCQ=0x4 sd 6:0:0:0: [sdh] CDB: cdb[0]=0x88: 88 00 00 00 00 00 00 08 f1 c0 00 00 01 00 00 00 end_request: I/O error, dev sdh, sector 586176 md: disk12 read error, sector=586112 md: disk12 read error, sector=586120 ata7: EH complete md: disk12 read error, sector=586128 md: disk12 read error, sector=586136 md: disk12 read error, sector=586144 md: disk12 read error, sector=586152 md: disk12 read error, sector=586160 I shutdown the sytem and replaced sata cable and power cable for disk12 but issue keeps coming back. I don't exactly what to do at this point. Here is what I have: 4TB disk1 drive that needs to be rebuilt Original 1.5B disk1 drive with valid data and that is working fine Valid 4TB Parity drive (I guess) since I haven't started a parity check since the data rebuild Spare (precleared) 4TB drive I was tempted to put the 1.5TB back and go the "Make unRAID Trust the Parity Drive, Avoid Rebuilding Parity Unnecessarily" way but since the configuration doesn't watch because of the size mismatch I'm not sure it will work. What would you recommend? Thanks Alphazo PS: here is the smartctl for disk12 smartctl -a -d ata /dev/sdh smartctl 6.2 2013-07-26 r3841 [i686-linux-3.9.11p-unRAID] (local build) Copyright (C) 2002-13, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Device Model: WDC WD40EFRX-68WT0N0 Serial Number: WD-WCC4E0083446 LU WWN Device Id: 5 0014ee 2b3ba9249 Firmware Version: 80.00A80 User Capacity: 4,000,787,030,016 bytes [4.00 TB] Sector Sizes: 512 bytes logical, 4096 bytes physical Rotation Rate: 5400 rpm Device is: Not in smartctl database [for details use: -P showall] ATA Version is: ACS-2 (minor revision not indicated) SATA Version is: SATA 3.0, 6.0 Gb/s (current: 3.0 Gb/s) Local Time is: Tue Nov 25 23:12:18 2014 CET SMART support is: Available - device has SMART capability.

I looked at the file using an hex editor and all the serial numbers were there. Since disk12 seems in bad shape I need the parity not to be overwritten so I can restore disk12 on a new blank drive. [Few hours later] I went ahead and replaced my super.dat by an older backup of it that had the 1.5TB registered. Started back the machine with the old working 1.5TB on disk1 and a brand new precleared 4TB on disk12. Disk12 is now reconstructing. Will investigate later the status of the faulty drive. Lets's see what comes out of this rebuild.

Big thanks to everybody for providing such valuable information. A pair of 4TB Red drives is on the way. I will only replace the parity drive. Funny to see that failure on parity drive is evolving (in the wrong direction) but ball is still solid green. I'm marking the thread as Solved for now. root@babylon:~# smartctl -a -A /dev/sdi smartctl 5.40 2010-10-16 r3189 [i486-slackware-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net === START OF INFORMATION SECTION === Model Family: Western Digital Caviar Green (Adv.

Hello, I was doing a random check on my unRAID server and noticed 4306 errors for the Parity drive (but ball is still green). I then ran a smartctl on all the drive and also found a high number of error on one of the data disk. I'm going to buy two new drive (and switch parity to 3TB). Which drive do you recommend me to swap first (parity or disk11) ? Should I run a parity check before?

From day one, this particular user share was setup including only one physical drive and excluding the others. This has never been touched. I also checked each of the /mnt/diskX drive but couldn't find any trace of the missing files.

I don't think it is related to rsync as my friend who has the same issue doesn't use rsync at all. It has many empty directories as well with lots of vanished files. In my case I have been using the same rsync script for many years using a source that still has the files. I also closely monitor rsync output to check what has been uploaded and deleted. FYI, I just ran a hashdeep between the known good source and the damaged user share and found about 3255 missing files out of 61565.

Hi, I have been running 5.0betaXX for many years and decided to switch to the release version. I started from a fresh installation disk using my old disk configuration. Before switching over to the new version I noticed that all my disks were 100% full. I found out that my backup script went crazy and filled up all my free space. I cleaned it up, ran a parity check and upgraded. Everything went very smooth. Recently I decided to perform my regular rsync task from my external HDD to unRAID (photos & videos) and noticed that old files were uploading even if I haven't used them for ages. I interrupted the process and looked at the user share and found out that I have more than twenty empty directories. I also looked at the physical drive (/mnt/user/disk1/PHOTOS) and found the same empty directory. For information, this particular share only uses one physical disk. I also don't use any cache drive. I have been able to sync the missing files but I now I'm very worried about the other user shares. Have I lost other files? Could this be linked to the 100% usage prior to the upgrade to 5.0 release? If not how can I investigate it? Talked to a friend of mine who is running the same setup and he has experienced the exact same problem and is unRAID is about 99% full.

I wanted to share my notes when migrating to 5.0 Release (from 5.0beta14). Most of the stuff and tweaks comes from the forum but I wanted to have a convenient place to share that with my other friends who are going to update soon. You can read it here: http://is.gd/xFyGd8

I just moved from a Chenbro ES34069 with 4 drives to a Norco RPC-450B based hardware with 10 drives (max 15 drives). I wanted a device that could hold more drives with a good air flow. I don't really care about hot-swap drive bays (too expensive and unRAID doesn't support hot-swap today) but also didn't want to spend too much time building my own drive bays. Furthermore I wanted something both heavy and not eye-catching so a potential "visitor" would be less tempted to take it over. As this beast is going in my garage, noise is less of an issue. I looked around and couldn't find any nice industrial chassis that would fit many drives out of the box. Then I found the Norco RPC-450B that would hold 10 drives with no screws have two front 120mm fans. It even has room for additional drives as there is an empty 3x5.25" bay. Priced at $78 this sounded a too good deal. Well I did pay that amount but living in Europe I also payed more than $100 for shipping and guess what the parcel got returned to the US the first time so I ended paying even more for a Fedex delivery. Assembly went well, built quality is ok but nothing like a Lian Li case. First things I replaced were the front fans (way too loud even for a garage). The result is acceptable but due to the two grids and dust filter in front of each them, the case is not quiet. Performance was up compared to previous Atom based platform but mostly on the write speed. I guess at the moment read speed is limited by the client PC. Last thing, I do recommend those metal grip SATA cables. They make your life much easier (and safer) when playing around with drives and SATA controllers.
