Yeah that was my concern. With two drives showing the seek errors and only being able to replace them one at a time and still keep the array parity protected I'm not sure the other drive would survive a parity rebuild... I was thinking i would have to do the break the array and restart parity and then copy the info from the removed drives as you said via unassigned devices. The data that is on those two erroring drives is just movies/tv shows which I've made a full listing of so worst case scenario i can just reacquire it if the drive dies completely in the middle of the process. So by doing a "New Config" it will not erase any of the existing disks in my array and allow me to rebuild a new parity based on the new drives Ive inserted plus those I'm keeping from the existing array?

Hello, Recently i had two drives in my array show up as failing SMART due to Seek Error Rate thresholds exceeded. They've since stopped showing this but i dont trust those drives now and I'd been planning on changing up my array anyway so I bought 4x16tb drives to replace those two and some others in my array. My current configuration is: Parity - 18TB Disk 1 - 8TB Disk 2 - 6TB - This is one of the dying drives Disk 3 - 6TB - This is the other dying drive Disk 4 - 3TB Disk 5 - 3TB Disk 6 - 3TB Disk 7 - 6TB Disk 8 - 8TB Disk 9 - 18TB Disk 10 - 6TB I want to remove the two drives that showed the SMART errors, and consolidate the 3tb drives and 6tb drives to single 16tb drives, shrinking my array configuration down to 8 drives from 11 and end up with the following configuration: Parity - 18TB Disk 1 - 16TB Disk 2 - 16TB Disk 3 - 16TB Disk 4 - 16TB Disk 5 - 8TB Disk 6 - 8TB Disk 7 - 18TB I'm hoping someone can suggest the best method to do this. I've only ever expanded my array by adding more or larger drives over the past 15 years, I've never actually shrunk the number of drives used in the array. My end goal is to end up with a smaller case and less power hungry setup to try and save on some electricity running costs as well as claim back some desk space. I've already pre-cleared the 4x16tb drives and they are all sweet. Any guidance would be greatly appreciated. Cheers,

Thanks for clarifying my options itimpl. I finished the array expansion overnight and all is working as expected. Cheers!

Hi, I currently have a 9 drive array. It consists of: Parity - 6Tb (X300 Toshiba) Disk 1 - 6Tb (X300 Toshiba) Disk 2 - 6Tb (X300 Toshiba) Disk 3 - 6Tb (X300 Toshiba) Disk 4 - 3tb (Hitachi 7200rpm) Disk 5 - 3tb (Hitachi 7200rpm) Disk 6 - 3tb (Hitachi 7200rpm) Disk 7 - 3tb (Hitachi 7200rpm) Disk 8 - 3tb (Hitachi 7200rpm) Ive just moved my system into a new case (a Meshify 2) which gives me capacity for 11 drives. I've bought 2 new 8tb Ironwolfs and plan to expand my array by 2 drives. Ive already pre-cleared both the new ironwolf drives and both came back clean. The new array configuration i want is: Parity - 8Tb (New Ironwolf) Disk 1 - 6Tb (Same position) Disk 2 - 6Tb (Same position) Disk 3 - 6Tb (Same position) Disk 4 - 3tb (Same position) Disk 5 - 3tb (Same position) Disk 6 - 3tb (Same position) Disk 7 - 3tb (Same Position) Disk 8 - 3tb (Same Position) Disk 9 - 8tb (New IronWolf) Disk 10 - 6tb (Old Parity) Ive had a search on the forum and seen the posts about the Parity Swap Method and other people saying just replace the parity drive but i'm confused and don't want to risk blanking my array and losing all my data. Previously when i've upgraded my drives i've built a whole new server and copied the data from the old server to new one but i dont have the luxury of doing that this time. So what is the best method for me to 1) upgrade my Parity to support the larger drives in the array and 2) repurpose the old parity into the array and add in the 2nd ironwolf? Any help would be greatly appreciated. Cheers! Edit: Forgot to mention i'm running Unraid Pro 6.8.3 currently.

For my personal situation I run my server off a UPS so I havent had an ungraceful powerdown for many years now. I also only use it as a media/file server. I don't run any complex dockers or VM's or anything that risk crashing the server. This is mainly because i only run this off a Celeron 550 with 8gb ram so it doesnt have heaps of excess grunt for those so perhaps the negatives of BTRFS wouldn't be a big obstacle for me compared to the positive of bitrot detection. Might do a bit more reading while i wait for the pre-clears to finish on those drives to see which path i decide to take Edit:OK ive done a bit more reading and i think i will just stick with XFS and run the risk with diskrot

OK cool thanks mate... So maybe my best approach might be to build a new array with the new drives and copy the content over to those and then add in the other drives one by one copying over the data to each after i make those into the new filesystem. So now which file system do i go with? is BTRFS better with its bitrot detection or does the stability of XFS make it the preferred filesystem?

Hi guys, Ive been running unraid for a long time now (~15 years) and have reached the capacity of my current server. I currently have 9x3tb drives in there and have just bought 4x6tb drives to start upgrading the capacity - the are currently undergoing preclear to ensure there are no issues with them. My existing array is using the reiserFS file system and ive noticed some posts indicating that XFS or BTRFS are the preferred options nowadays. I dont have slots in my server to include more drives so will be replacing 4 of the existing 9 drives (including the parity). Ive been trying to find a definitive guide on how to upgrade my server capacity and also change the filesystem but im still confused. I obviously have to replace my parity drive first with a 6tb drive to make sure that it is the largest drive in the system but when i go to replace the other drives one by one and do the rebuild of my data on to them will it rebuild back to reiserFS or can i tell it to change to XFS/BTRFS and if so which is the best option to choose? cheers!

Well.. I broke down the server yesterday... pulled the HSF off the CPU and gave it a vacuum as it was a tad clogged.. put it all back together and ran memtest for 12 hours - multiple passes with zero failures.. Started the array back up in maintenance mode and ran a reiserchk on all 8 of the data disks and all reported zero issues.. disk 5 had 1 safe link but apart from that nothing stood out.. It also completed a parity check overnight without parity errors.. hopefully it was just the CPU overheating from the dust and all will be ok now.. ill let it run normal now and see if the issue presents itself again.

Lol.. thought I put the 6.1.9 in the original post but it says 2.1.9 instead. The high temp is probably because we've had a heat wave here in the past few weeks hitting 47c on several days so the air con has been struggling. I'll break the machine down today and make sure it's all clean inside and then do the file system check. Thanks John. Ive been running unraid for about 8 or so years now so started long before all the docker and VM stuff i love unraid just because it works perfectly as a media server for all my machines although i am now starting to consider building a VM capable server so that i can run both my storage and my everyday desktop on there and do away with a seperate machine.

Hi guys.. I have a server which has been running 24/7 for a few years now without issue until this week. I am experiencing an issue whereby all my /mnt/Disk1, /mnt Disk2 etc Samba shares stop responding. I can access the GUI via the browser and run commands but if I try and access any of my drives from windows explorer or from any of the media players on any of my PC's on the network it just times out. It first happened on monday this week and now has just happened again. If I try and stop the array it via the button on the Main GUI tab it gives me the across the bottom of the screen and then the GUI freezes up after a few minutes also. "Stopping Docker...Stopping libvirt...Stop AVAHI...Stop SMB...Spinning up all drives...Sync filesystems..." After this I was forced to hit the reset button and then go through the parity check process due to the unclean shutdown. It passed the parity check on powerup after a few hours with zero errors detected. Today I came home from work and I had the same issue. All shared drives were unresponsive but i could access the GUI and draw down a diagnostics zip file which I've attached. Don't have the faintest idea where to start with this one. Could it be an issue with SAMBA dying or am i looking at a dying drive or something else altogether? Server details are as follows: Unraid 6.1.9 ASRock - B75 Pro3-M Intel® Celeron® CPU G550 @ 2.60GHz 8gb Ram M1015 HBA 9x 3tb Toshiba ACA drives (8 on m1015 and parity on the mobo) Any help would be greatly appreciated thanks guys. Cheers. theburrow-diagnostics-20170217-1625.zip

So in your dealings with asrock tech have they indicated they can replicate these issues people are appearing to have? Sent from my Galaxy Nexus using Tapatalk

I'd like to see some power usage stats for these avotons from a kill-a-watt if you guys have one. Sent from my Galaxy Nexus using Tapatalk

This would have to be damn near a perfect case for most setups. I've only just recently dropped from 3x5-in-3 hotswaps to 3x3-in-3 hotswaps. If this had of been available at the time for sure I would have grabbed this instead. Will definitely consider this for any future builds I do. Sent from my Galaxy Nexus using Tapatalk

I'm same as lagamm above. Purchased my initial key in 2008 so coming up on 6 years running without fail. Mostly 24/7 system uptime that whole time. USB stick is an old lexar firefly 4gb which was the recommended stick at the time. I've had 3 hard drive failures in that 6 years and a motherboard failure also so don't really see the USB drive as the weak point given Unraids usage pattern.

I picked up 9 of the Toshiba DT01ACA300 7200rpm 3tb drives recently. These have a 3 year warranty here in Australia. My first 3 completed pre-clear last night. Two of the drives took 24.5 hours and the other took 26 hours. Not sure why the 3rd drive took longer but they all passed with 0 errors. Drive temps maxed at 37 deg C. It's quite warm in Australia atm tho. Started pre clear on the next three straight after. With the 3 year warranty and with them being faster and $50 per drive cheaper than the WD reds its sort of a no brainer. Sent from my Galaxy Nexus using Tapatalk 2

Picked up 9 of these drives today. The local distributor here in Australia has decided to offer a 3 year warranty on them so that made my mind up. On 2 weeks holidays from work so will start queueing up the pre-clears I guess. Hopefully I'll get them all done before I have to return to work. Sent from my Galaxy Nexus using Tapatalk 2

I'll be curious to see reports of your temps and speeds. Still not much info out there. In regards to warranty its only 2 years here in Australia so definitely varies from country to country it seems. Sent from my Galaxy Nexus using Tapatalk 2

Euro based providers seem to be a bit more resistant to the DMCA pressures. Has to be a true euro provider though not just a provider like Astraweb who offer both US and Euro servers. Sent from my Galaxy Nexus using Tapatalk 2

Thanks for that Lionel. Those temps are pretty good for 7200rpm vs 5200 rpm drives. Think I will just go with 9 of the ACA drives then. Sent from my Galaxy Nexus using Tapatalk 2

So for those of you that already have these drives how are the temps when they are spun up? I'm debating getting 9 of these right now or waiting a few weeks/months till the ABA 5900 rpm versions are released. Will be running the drives in 3in3 hotswap modules so they won't be too tightly packed. Sent from my Galaxy Nexus using Tapatalk 2

mm.. if the P5Q-EM works ok then the P5Q-Deluxe should i'm guessing.. saves me having to get a new mobo/cpu/ram combo for my reconfiguration. Thanks for the post.

I'd like to know this too.. I'm about to update my system which is a P5Q-Deluxe with Intel 6600 and 2xAdaptec 1430SA's which runs 15x1tb drives. Cutting down to 9 drives but increasing capacity to 3tb drives and replacing the two 1430SA's with an IBM M1015 whilst intending to keep the P5Q-Deluxe. Will be running the 8 data drives on the M1015 so will need to run the parity drive off one of the mobo ports. Just not sure if the P45/ICH10R will handle the 3tb+ drives ok atm. Not really wanting to have to update the mobo and CPU as well if I dont have to at this point. My other option is maybe pulling my Asus M4a785-M Evo / AMD Phenom II X2 550 out of my HTPC to use if that supports 3tb drives?

Yes you are right. WD acquired Hitachi, but the Hitachi 3.5" business was sold to Toshiba to allay Anti-Trust concerns. I've done a bit more research and found an image of the drive sticker showing the drives are manufactured in China by Hitachi Global so looks like might indeed just be 7k3000's with a new sticker. In regards to the ABA300 drives i've read that the Toshiba Canvio Desktop 3tb drives are supposed to hold 5900rpm drives so the ABA's might be getting channeled to this market instead of to the bare drive market for the moment. I'm still trying to work out what Toshiba's warranty policy is on cracking open external drives to get the drive out to use in a desktop machine. If they honor the warranty (like Hitachi did) then it might be worth picking up a bunch of the Canvio drives to get the ABA's if it turns out thats whats inside.

One thing I have seen is that the Toshiba drive has an optional power savings mode that drops the idle power draw from 5.2w to 2.4w. Seems there will also be 5900 and 5200 rpm models. http://benchmarkreviews.com/index.php?option=com_content&task=view&id=19712&Itemid=47 Probably still about 3 weeks from purchasing. Was just hoping someone else had more info than the scant amount I've found so far. Sent from my Galaxy Nexus using Tapatalk 2

Anyone used a Toshiba 7200rpm 3TB drive (Model number:DT01ACA300) in their unraid system?? They are the cheapest 3TB drive I can get locally here in Australia and come with a 2 year warranty. They are 3x1tb platter, 64mb cache drives and appear to be 4k aligned i think. Have only been released to market in August this year? Just wondering if anyone has any experience with them yet and if so was it positive or negative in regards to unraid? How are the temps for a 7200rpm drive? Having trouble finding much info or reviews on these atm. Thinking about picking up 9 of them as I can get them for over $50 per drive cheaper than the WD Reds atm which is a $450 saving for the 9. Intending to use them on a M1015 card. Edit: seen some references to the fact that these might be basically Hitachi 7k3000's as they were/are made in the same factory.. if so its a nice price differential on the 7k3000's which are rare as hens teeth here in australia...
