Hi guys, this is a simple plugin that allows users to clear their disks before add them to the array. The main characteristics of this plugin are: Modularity: can be used standalone or in conjunction with Joe L. or bjp999 scripts; Ease of use: with a few clicks you can start a clear session on your disk; Integration: you can always access the plugin under Tools > Preclear Disk menu. If you have Unassigned Devices installed, you can start/stop/view preclear sessions directly from Main > Unassigned Devices. All dependencies included: you don't need SCREEN to run a preclear session in the background; all jobs are executed in the background by default, so you can close your browser while the preclear runs. You can install it directly or via Community Apps. Q & A: Q) Why Joe L. or bjp999 scripts are not included? A) I'm not authorized by Joe L. to redistribute his script, so you need to download a copy from the topic above and put it under /boot/config/plugins/preclear.disk/ renaming it to preclear_disk.sh if necessary. bjp999 modifications are unofficial, so I decided not to include it by default. A) the bjp999 script is now included by default. Q) By default, I see a "gfjardim" script always available. Why? A) Since I'm not authorized to redistribute Joe L. script and the recent slow support by the author, I decided a major code rewrite in the script was needed. The new script is being actively supported, compatible with unRAID notifications, is faster than bjp999 script and has a cleaner output so users can easily visualizes what's going on with their disks. Q) I want to use one of the older scripts(Joe L. or bjp999) in conjunction with notifications. Is that possible? A) Yes. I've made some adjustments on both scripts so they become compatible with unRAID notifications; Joe L. version can be found here and bjp999 can be found here. A) the bjp999 script is now included by default; it includes support for Unraid notifications. Q) Is there any howtos available? A) gridrunner made a awesome video explaining why preclearig a hard disk is a good idea, and how you can accomplish that: Q) The plugin asked me to send some statistics information. How does the statistics report system work? Is it safe? Is it anonymous? A) To better track the usage of the plugin, a statistics report system was put in place. The main goals I intend to archive are: know number of disks that gets precleared; fix any silent bugs that gets reported on the logs; know average size of disks, their model, their average speed and elapsed time we should expect from that model; success rate; rate of disks with SMART problems; This system is totally optional and users will get prompted if they want to send each report. It is also safe and totally anonymous, since all data is sent to Google Forms and no identifying data is exported, like disks serial numbers. Detailed info can be found here. The statistics are public and can be found here. Q) How can I download a copy of the plugin log? A) Please go to Tools, then Pleclear Disk, and click on the Download icon: Q) Which are the differences between Erase and Clear? A) The Clear option uses zeroes to fill the drive; at the end, the drive can be added to the array the array immediately. The Erase All the Disk option uses random data to wipe out the drive; the resulting drive can't be quickly added to the array. If you want to add if after erase, you must select Erase and Clear the Disk. Troubleshooting: Q) After Zeroing the disk, the Post-Read operation fails saying my drive isn't zeroed. A) When zeroing the disk, the script uses a zero filled data stream produced by the pseudo-device /dev/zero. If a Post-Read fails just after a Zeroing operation, chances are that you have bad RAM memory, or less frequently bad PSU, bad cables or bad SAS/SATA card. Please run some rounds of MEMTEST on your machine to test your RAM modules. Q) A Pre-Read operation failed and I see Pending Sectors on the SMART report. A) Pending Sectors will lead to read errors, and the Pre-Read operation will fail. To force the hard drive firmware to remap those sectors, you have to run a Preclear session with the Skip Pre-Read option checked. Q) I've lost communication with the webgui, can I manage preclear sessions from the terminal? A) Yes, you can. If you lost communication with the webgui or want to use the command line interface to manage your preclear sessions, you just need to type preclear on your terminal to start/stop or observe a preclear session.

Ransomware Protection This plugin is a specialized type of anti-virus designed to detect if a ransomware malware attack is happening on your server, and upon detection either take the server offline, or make all of your user shares read-only. It operates by using "bait files". These bait files can either be located within you normal user shares, or within specialized bait shares. Once an attack happens on one of the bait files, (either the contents are changed (ie: encrypted) or deleted (ie: renamed and encrypted), the plugin will take whatever action you specify. Response time is approximately 1/10th of a second. Full details on the setup and operation of the plugin are contained within the "Help" tab on the plugin's settings page You can install this plugin via Community Applications (the Apps tab) within the Plugins section (or just search for ransonware). This plugin requires unRaid 6.2+

Because it's using php7 so the command uses php7

Amazon has them at 179.99 now Seagate Expansion 8TB Desktop External Hard Drive USB 3.0 (STEB8000100)

Noticed recently that Fix Common Problems shows that call traces were found. What causes this and how can I fix? Hopefully it's not a severe problem. unraid-diagnostics-20170417-2020.zip

bulk data imports on a array that is limited on write speed (aka unraid array) is very possibly the issue, without cache drive your write speeds will be low, and sqlite is not good at managing unusual situations, such as IO limitations. writing to a cache drive is the way forward, speeds are SIGNIFICANTLY improved when writing to cache drive, i would delete the half baked metadata on your array drive, get that migration finished and then go from a fresh start on cache drive. btw this doesnt have to be like this:- simply dont set the shares to use the cache drive and you wont have this issue, it will write straight to the array, i dont use the cache drive to cache writes to shares (as dont many people), so i simply dont set any shares to use it and disable unraid "mover" job done.

On Putty go to Window -> Translation and choose UTF-8 as Remote character set.

I keep having issues logging in. I log in and it just goes back to the login page. I have to keep clearing my cookies to get it to work. It has worked fine for a long time then this started happening a few weeks ago. Seems to only happen with Chrome, but I can;t be certain of that. Anyone else had this issue?

Updated container coming soon, @sparklyballs outdid himself with the detective work here I have to say.....

You can't. As a workaround, try placing the options at the end of the repository field.

Try looking in the flash drive /config/ssh/ your keys may have got corrupted. Delete them and reboot, they'll be recreated at reboot. Sent from my LG-H815 using Tapatalk

Yes. I have 8TB drives on mine now. If the controller supports >2,2TB drives then it will support all drive sizes for the foreseeable future. Will be a long time before drive would be too big. You are more likely to need a new interface to connect a drive before a drive will be too big.

so you have made a windows 10 image from a real machine? It doesnt boot when you try and run it gets stuck on uefi boot. Please try to setting up as bios type to seabios then run the vm.

Oh I agree, I'm not one looking to populate a NAS with 2.5" drives, so the CS280 didn't even get a second glance from me. Regarding the DS380, I have never been a fan of that case. Admittedly I was quite excited when it first made an appearance, but after going through numerous reviews, it just looks...painful to work on. I am currently rocking a node 804, which is also not without its foibles. The CS380 looks to offer excellent functional performance and good capacity. I guess my only (initial) criticisms would be styling and uncertainty with filtering on intakes (a filter that requires you to open the case to clean it is next to pointless imho), and nobody is putting that case in their HT cabinet to show it off. The CS380 is the kind of case that I have been waiting for. Modern HDD capacities are really negating the need to build 20 drive rackmount monsters for a lot of people (I considered it for a loooong time). Backplanes, room for cable management, easy HDD access, decent cooling. I am super keen to get some more details on this case.
