You might look at the LSI SAS9211-8i (That is the 8 port card, there are also 4 port and 16 port versions) I just looked on ebay and there are quite a number for sale in the $60 - $90 price range.

Try a different USB port, USB2 is more reliable than USB3, failing that get a new flash drive.

So I added 3 of these Seagate Archive 8TB drives into my 4TB HGST 7200rpm array. I'm seeing good speeds for my Parity Checks regardless of the mixed drive situation. The check is now around 18.5 hours. Very acceptable to me for the additional 20TB of storage I gained.

A lot going on in there... but for one thing it appears your cache disk/pool is full: Apr 24 18:03:18 Raptor shfs/user: share cache full Also, you're better off posting diagnostics.zip file since it will anonymize some info in the logs and provide more information needed to troubleshoot. Finally, please don't cross post.

Take a screenshot of your drive assignments. Prepare the new flash as for a new install. Reassign your drives. You can just delete everything from cache if you want, since you won't have any dockers/VMs setup yet that will try to use anything on cache.

Don't buy that, PCI and SATA1, get one that is PCIe and SATA2 or 3.

Most users don't have issues it it, but there are enough with problems to make it not a recommended controller, I also have 2 and never had issues, though they are in servers with vt-d disable. I'd say if you're going to buy new definitely get an LSI, if you already have one use it, most likely you'll be fine.

I've NEVER had an issue with the SAS2LP, in multiple machines in unRAID. Yes, other Marvell cards can suck, but had no issues with the Supermicro.

The SuperMicro AOC-SAS2LP-MV8 and other Marvell-based controllers have come under fire here for not being compatible with passthrough VM technology. There are workarounds and many users find they help, but might suggest doing some more homework, and possibly looking at an LSI card if you are buying new.

Johnnie I followed your instruction for replacing cache procedure and restored to the same SSD. This didn't solve the issue I had, though started a couple others. A set of phaze's plugins that I was using, with their storage on the cache drive under a share called persistent storage have all become uninstalled. Now my winSCP is not able to connect to the server as well whereas it was working great all this time. The only good news is that my files are intact I have deleted all my dockers and VMs, but I would like to completely reset my unRAID's settings while keeping the files, how can I do that? The idea in my head is some kind of factory reset or fresh installation while keeping the data. I would really like to start anew, and sort this problem out at the very roots. What should I do with my cache pool of two 128 and 180 GB SSDs? How should I format(?)/preclear them? I have just purchased a big UPS, so unclean shutdowns and data corruption are solved. I will also not be using plugins for plex, couch and sickrage now, and set them up in docker. Thanks!

You can use the replace cache procedure, but instead of replacing just format and restore to the same device:

Parity sync does not fix anything related to corrupt file systems/metadata. For that you have to use the file-system specific tools.

This means the metadata doesn't match the data, i.e., metadata was written but due to device errors or an unclean shutdown not all corresponding data was written, since it's an SSD and if there were no unclean shutdowns it's usually a cable problem. btrfs fsck is not yet very reliable, best way to fix this kind of error is to backup your cache, reformat and restore the data.

It's not necessary to forward any port in your router to allow any computer on your LOCAL network to access any port. You shouldn't try to access your unRAID webUI from outside your local network without setting up a VPN.

You only need to forward the ports the apps themselves might require. And there won't be many. Port forwarding is only used for the outside world to communicate with an app. Not for an app to communicate with the outside world. You never forward port 22 or 80. If you require ssh access outside your network use a vpn Sent from my LG-D852 using Tapatalk

First off, you are under attack from Vietnam, Russia, and Great Britain (damn brits). Take your server out of your router's DMZ. There is zero reason to have it in there. (Also make sure you set up notifications on your server. Fix Common Problems will alert you to any future attacks) The crashing: It started with this: Apr 17 09:15:21 APURVA-SERVER kernel: kernel BUG at fs/btrfs/ctree.h:1763!

Hi Guys, This is a tutorial for using a GUI file manager in unRAID. You will learn how to install and configure Sparklyballs' docker container 'Krusader' in a docker container so you can easily manage your file, folders and shares. You will see how to easily transfer data to your server when setting up a new build. Also, you will see how to backup data and move data around the array. You will see how to compare and sync folders and connect to other servers and computer with the file manager. To finish you will see some tips for getting the most out of Krusader. Hope some of you find it useful Easily move copy and sync files to unRAID, within unRAID and from unRAID using Krusader
