I think it maybe a cable failure that was causing my CRC errors. I was getting errors even after replacing the cache drives. I swapped out the cable and I think I'm good. As for the old 500GB EVO 840, I ran about 500B of data through it on USB 3.0 and it seems fine.

I got the 250GB Intel 545S, it has 144TBW.

You have to read the fine print ... 300TBW is on the 2/4TB models which is pretty bad for a drive of that size. The 250GB model only has 75TBW for the EVO 850. EVO 860 on the otherhand has like 2.4PBW for the 4TB models and 150TBW for the 250GB model. The Intel 525S and EVO 860 have the best endurance and warranty for consumer drives as far as I'm aware of at the moment. I ruled out Samsung because they only sell greymarket in Canada - the RMA process is awful here.

I ended up getting two Intel 525S SSDs. These drives are pretty cheap, have a 5-year warranty, and are very durable - 144TBW for the 250GB model which is on par with the Evo 860 (150TBW) and much better than the Crucial MX500 (100TBW).

Anyone have a recommendation for a Cache drive? My EVO 840 seems to have died and I'm considering either 2 x Crucial MX500s or 2 x WD10JFC (2.5" WD Reds). Any other options I should look at? I'm thinking of avoiding Samsung because it has bad warranty service in Canada (near non-existent). Thanks.

Thanks for the quick replies @jonathanm and @johnnie.black. My EVO 840 started throwing errors BTRFS errors for the second time in 2 years ... I'm still not sure if it's a SSD error or BTRFS problem with unRAID. But either way, looks like I'll be replacing the drive ?

Hi all, My BTRFS cache is acting up and I like to move my AppData back to the array. I've set Cache to No in the share settings, but unRAID is giving me the following error when I run mover: Fix Common Problems: Warning: Share system set to not use the cache, but files / folders exist on the cache dr What is the procedure to move Cache data back onto the array? Thanks.

Thanks - I just installed a 10TB Hitachi and my SMART values messed up. This fixed it!

Doesn't the Storinator 45 use a RocketRAID 750 card which has the Marvell 88SE9485 chipset? Marvell chipsets cause a parity bug with unRAID... was this an issue with the Storinator?

I got NUT working with my Smart-UPS 1400XL 3U in about 5 minutes... does this version of Nut come with a graphing web interface? If not, can anyone recommend a good graphing solution? Another thing, in the UPS driver drop down, I'm surprised there is no option for APCSmart? Considering APC is one of the most popular brands of UPSes, I thought the Web GUI should have that as an option? Thanks.

Congratulations on the release? To all the early adopters... so far so good? :-) I'll probably give it a try tomorrow or next weekend.

Hello Everyone, I like to get the Disk Number to Linux Dev ID - I need to write a script to set the APM level of the drive to off and need the /dev/ identifier. My Seagate Desktop Barracuda drives Load Cycle Count is rising at about 40,000 per year (not too bad, but still more than I would like). Is there a way to get this easily from the /mount information in unRAID? Or even better, is there a plug-in or way to disable / set the APM state of the hard drives? Thanks.

Yeah, I tried this, but even on a 2460x1440 screen, I have to scroll up and down each time I change drives It would be neat if we could get a table format of all SMART data (i.e. one row per drive, each column is a smart attribute). Synology does something like this with their HDD Management screen. @pwm, thanks for letting me know about the Tools/Diagnostics zip file, I think this might be the easiest way for me to get the data. Thanks.

unRAID isn't the right choice for video editing since unRAID doesn't stripe drives (i.e. RAID 0) to increase read/write speeds. People editing videos want extremely high read/write speeds. Your best choice is to buy a DAS (Direct Attached Enclosure) and set it up for RAID 10. Sans Digital has off the shelf consumer hardware, but there are also a lot of other choices.

Buy a small open rack - they hold like 2000 lbs But I would budget about 85 - 100lbs for the server with hard drives installed (40lbs for the chassis and 1.5lbs per drive). Also, I recommend you have good access to the back of the server - it's nice to be able to cable the back of the server without removing it.

Hi, is there a way I can get a bulk SMART report - i.e. a listing of all the drives without needing to click through each one in the Drives menu? I just like to see which is my oldest drive and hence the one to replace. Thanks.

unRAID doesn't supporting clustering or stacking, although with the Unassigned Drive Plug-In, you can map remote shares to the server. This way, you log into one server and remote severs can also be reached through the one UNC path. As for cases, look at a rackmount chassis with a SAS expander - this way one SAS card can service the entire chassis. The Noroco cases are pretty popular - they have a new model with a single SFF-8644 12gbs SAS expander support. The RPC-4244 is popular choice too, it has 6 internal connectors, so you can probably run the entire chassis off a card or two or use a single SAS Card + RES2Sv240 expander connected to the on board expander on the RPC-4224. A cheaper alternative to the Intel RES2Sv240 is a HP SAS Expander Card although it's less flexible in terms of installation than the Intel card... but it's cheap! One more option you may want to consider - instead of having separate servers, you may want to chain additional drives into an external enclosure like a Direct Attached Storage. You can build your own using the RES2Sv240 card or buy a premade system: https://www.servethehome.com/byo-sas-expander-deal-intel-res2sv240-sas-2-expander/

This is slightly embrassing ... it's no unRAID but my eSATA array. For some reason my eSATA RAID 5 array drops in speed significantly after the first file. Writing to my local hard drive I can get pretty good speeds (70MB/s - 110MB/s). So... I guess the problem is resolved

I can easily recreate the issue too - all I need to do is stop the file transfer in Windows, restart it and the file will transfer at full speed. I guess I never noticed the slowness of the server since I usually only copy a handful of files. But I'm trying to offload TB of data and this is a PITA right now. Another thing I noticed is the Page In value for SMBD is very high. I'm not sure if that is normal or not? I'm assuming it is since SMBD needs to read disk data and send it over the wire, hence it's paging data in? I have minor page outs, but doesn't look to be anything serious: 7877704 K total memory 180512 K used memory 547992 K active memory 6820048 K inactive memory 222796 K free memory 10128 K buffer memory 7464268 K swap cache 0 K total swap 0 K used swap 0 K free swap 8678 non-nice user cpu ticks 5644 nice user cpu ticks 35351 system cpu ticks 470865 idle cpu ticks 117521 IO-wait cpu ticks 0 IRQ cpu ticks 4311 softirq cpu ticks 0 stolen cpu ticks 57845899 pages paged in 132002 pages paged out 0 pages swapped in 0 pages swapped out 7771146 interrupts 12677600 CPU context switches 1514913184 boot time 188674 forks IO-wait time is very high and keeps incrementing. I don't think it's my SAS card (LSI since parity and rebuilds run fast), what about the network card? I'm using an AR8151 card. I'll try safe mode and get back to you.

Hi all, I see that others have raised issues about slow read speeds with unRAID ... and I seem to be in a similar situation. This is what's happening: First file, even if it is multi-gigabyte, transfers really quickly, at full wire speed (110MB/s) Second, third file, may or may not transfer at full speed, usually drops to 55MB/s By the fourth file, it's around 20MB/s - 25MB/s I tried the extra SMB option as well as enabling Direct I/O... but this has not fixed the issue. No other apps are running on the server itself. What can cause such a drastic slowdown after the 1st file? Running TOP on the server, I noticed that my load averages are *very* high... top - 10:17:55 up 4 min, 1 user, load average: 11.44, 4.02, 1.47 Tasks: 339 total, 1 running, 338 sleeping, 0 stopped, 0 zombie %Cpu(s): 12.2 us, 15.1 sy, 0.8 ni, 64.2 id, 5.5 wa, 0.0 hi, 2.3 si, 0.0 st KiB Mem : 7877704 total, 2851652 free, 474936 used, 4551116 buff/cache KiB Swap: 0 total, 0 free, 0 used. 6159348 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 19081 root 20 0 16736 3028 2280 R 11.8 0.0 0:00.02 top 9426 root 22 2 173552 22208 17096 S 5.9 0.3 0:03.05 php 1 root 20 0 4360 644 584 S 0.0 0.0 0:09.17 init 2 root 20 0 0 0 0 S 0.0 0.0 0:00.00 kthreadd 3 root 20 0 0 0 0 S 0.0 0.0 0:00.49 ksoftirqd/0 4 root 20 0 0 0 0 S 0.0 0.0 0:00.00 kworker/0:0 5 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 kworker/0:0H 6 root 20 0 0 0 0 S 0.0 0.0 0:00.00 kworker/u4:0 7 root 20 0 0 0 0 S 0.0 0.0 0:00.58 rcu_preempt 8 root 20 0 0 0 0 S 0.0 0.0 0:00.00 rcu_sched 9 root 20 0 0 0 0 S 0.0 0.0 0:00.00 rcu_bh 10 root rt 0 0 0 0 S 0.0 0.0 0:00.05 migration/0 11 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 lru-add-drain 12 root 20 0 0 0 0 S 0.0 0.0 0:00.00 cpuhp/0 13 root 20 0 0 0 0 S 0.0 0.0 0:00.00 cpuhp/1 14 root rt 0 0 0 0 S 0.0 0.0 0:00.05 migration/1 15 root 20 0 0 0 0 S 0.0 0.0 0:00.61 ksoftirqd/1 16 root 20 0 0 0 0 S 0.0 0.0 0:00.00 kworker/1:0 17 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 kworker/1:0H 18 root 20 0 0 0 0 S 0.0 0.0 0:00.00 kdevtmpfs 19 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 netns 20 root 20 0 0 0 0 S 0.0 0.0 0:00.00 kworker/u4:1 87 root 20 0 0 0 0 S 0.0 0.0 0:00.00 kworker/u4:2 280 root 20 0 0 0 0 S 0.0 0.0 0:00.00 oom_reaper 281 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 writeback 283 root 20 0 0 0 0 S 0.0 0.0 0:00.00 kcompactd0 284 root 25 5 0 0 0 S 0.0 0.0 0:00.00 ksmd 285 root 39 19 0 0 0 S 0.0 0.0 0:00.04 khugepaged 286 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 crypto 287 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 kintegrityd 288 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 bioset 290 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 kblockd 291 root 20 0 0 0 0 S 0.0 0.0 0:00.08 kworker/1:1 292 root 20 0 0 0 0 S 0.0 0.0 0:00.04 kworker/0:1 459 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 ata_sff 477 root 0 -20 0 0 0 S 0.0 0.0 0:00.00 devfreq_wq I'm running unRAID on a Celeron G1610 - so it's quite a slow machine, but surely reading/writing files over SMB shouldn't take this much CPU?

Hi all, Does anyone have a recommendation for a USB HDD Dock that will support 8TB+ drives? The dock I've been using doesn't seem to recognize drives >4TB. I don't need a fancy dock, I only use it for pre-clearing drives. Thanks.

Is Cache_Dir incompatible with OSX? It seems OSX will do a disk read no matter what, leading to it bypassing the directory cache? I wonder if OSX is trying to read the .ds_store file containing the folder meta data. If so, it would be good if unRAID has some way of keeping the .ds_store file on a SSD cache, thereby negating the need to spin up the whole array to read these small files. Does anyone know if there is a way to do that?

I have 8GB of RAM. I run Transmission as a docker - with maximum of 5 downloads. Ever since I made the tweak I haven't received and OOM error.

Personally I used 1% and 2% and it seems to have fixed my OOM errors. I was getting OOM when Mover ran.

Hello, Lately, my unRAID server becomes unresponsive after a few days. I can still SSH in... and the Web GUI mostly loads but the server is SLOW.
