your server restarted at this morning. here is the first line in the syslog. Oct 9 02:28:12 Tower kernel: microcode: microcode updated early to revision 0x27, date = 2019-02-26 You are also getting segfaults near the end of the syslog. I believe these are usually memory related. You might want to run memtst (from the boot menu) unless you have ECC memory. I would also double check that you didn't unlock any of the memory sticks when you were doing the drive changes.

First thing. Google Krusader Manual Second thing, NEVER copy between a User Share and a Disk Share!!!! If you do, you will lose data because you will eventually copy a file onto itself! If you want more details read here: https://forums.unraid.net/topic/32836-user-share-copy-bug/?tab=comments#comment-316512 Third thing, The Krusader panel in noVNC Browser Tab is a typical Windows/MAC interface. Almost everything you can do in either of those two OS's in a file manager, you can do in Krusader-- Drag-and-drop, Selecting a file/directory with a left-click and then right-click on on the selection will give you a dropdown menu. Basically, you work between the two panels, you copy/move files between them. The <Tab> key will take between the two panels. Clicking on the .. at the top of either window will take to the parent directory of the current directory until you get to the top of the tree. Double left-clicking on a directory will open that directory. Absolutely NOT! Or you could not preserve parity. Remember, you are at the OS super-user level. You can do anything and you won't be prompted "Are you sure?". When you are using Krusader, it is assume that you know what you are doing. You tell it to delete a file and it is gone... (Of course, the way it is setup, you can't get to the Unraid OS level only to the Krusader OS level. So there is a bit of protection there but you still have access to all of the data files and, possibly, even to the Unraid flash drive.)

One way to help is to install the Fix Common Problems plugin. That plugin have a setting for the maximum number of invalid login attempts in a day. Then change your password to one that is at least 8 characters long and something difficult to guess since it is your brother. You also need to physically secure your server which may be much more difficult. Make sure that you have setup the certificate on your server so that you are using https.

Copy all the bz* files from the root of the Zip file to the root of the flash drive.

Get your Diagnostics file Tools >>> Diagnostics and attach them to a new post.

Not going to approve (or disapprove any conversion procedure), but here is the link to the Bible (I used the Mirror each disk with rsync, preserving parity method when I did it.): https://forums.unraid.net/topic/54769-format-xfs-on-replacement-drive-convert-from-rfs-to-xfs/ EDIT: if the emulated disk has some corruption that would probably mean that there is a problem somewhere else on your array. It would probably be best if the problem were on the parity disk.

Interesting, look at the output of this command: root@Rose:~# sysctl -a | grep dirty vm.dirty_background_bytes = 0 vm.dirty_background_ratio = 1 vm.dirty_bytes = 0 vm.dirty_expire_centisecs = 3000 vm.dirty_ratio = 2 vm.dirty_writeback_centisecs = 500 vm.dirtytime_expire_seconds = 43200 I understand why the vm.dirty_background ratio is 1% and vm.dirty_ratio is 2% (that is what I set them to awhile back to prevent out-of-memory issues) but the vm-dirtytime_expire_seconds of 43200 is 12 hours! That says the data could sit there for 12 hours before it is forced to disk...

You need to post up your diagnostics file so the we have something to use to examine the situation. Tools >>> Diagnostics Be sure to post these in a new post or no one will ever know you did it. It might also be helpful of you could expand a bit on exactly what you did. How did you 'pop another drive in' and what is the 'the other disk'? Use disk id's when applicable.

I almost hate to say this but I believe this is a bit in error. These settings (as I recall) control the amount of RAM is permanently set aside for the delayed-write to--disk buffer so that lack of user perceived response during disk writes was minimized-- typically, typing on the keyboard and not having the characters appear on the screen until several seconds later when they suddenly appeared in a burst. (This was back in the days of much slower single core CPU's and much smaller amounts of RAM.) As I understand, Unraid is suppose to automatically use any unallocated RAM as a RAM cache. But with the addition of Dockers and VM's, I wonder if, somehow, there are some other factors now entering into how this is actually implemented. Perhaps, someone from @limetech could comment.

You have double left-click on the directory you want to be in. The ( .. ) is the parent directory of the current directory that you are in. By the way, I reconfigured my 'Host Path 2' as follows. (I did not rename it so it might be a bit confusing.) As I recall, this allowed me to get to more places that I wanted access to. Of course, greater access means that I can do more damage if I am not careful... 😈 EDIT: Please do not use http(s) links to photos (or files). You can insert photos directly in the text box.

You could use the 'Unassigned Devices' plugin and put the data drives in a USB housing. Then you copy the files back from the USB drive which is directly connected to the server. Plus, I would question your decision to go with a 4TB drive. Move up to an 8TB drive (minimum) to get yourself a bit of breathing room on storage capacity. Get two or three of your drives out of the current setup to free up some drive slots and get a parity drive installed. (Remember the question is, not if a hard drive will fail, but when...) Either that or get a larger case that will support more drives. One more quick point. Do you have at least one more backup of all irreplaceable data? (There is another poster today who has probably lost some irreplaceable data because he did not have a backup. And you should have a backup that is off site. There is a greater possibility of losing data through the total destruction of your residence then from a drive failure in a properly monitored and maintained dual parity setup!)

As I remember, when a file is created, two things happen. First, an entry is created in the File table which contains such information as the name of file and, second, the location of the first sector where the data is to be stored. So even if the file has no data, that sector is still allocated and will be until you delete the file.

When looking for a fan to reducing heating issues, avoid any fan that advertises 'Quiet' as an attribute. You want the fan to be able to move a large volume of air against a high static pressure and those are never quiet. Sure, some of these will make more noise than others but none of them will be truly quiet-- only less noisy!

For irreplaceable data, there has long been The 3-2-1 Backup Rule which can basically be stated as follows: Your unraid server can be one leg of this rule. (My offsite copy is on a 1TB External HD in a safety deposit box.) I realize that it may be too late for you but, perhaps, your experience may be be a warning for others. One thing you can do is to check immediately the other seven disks that should still be readable to see if any of that irreplaceable data is one (or more) of those disks and make two more copies of it ASAP! (Remember Unraid stores your data in a standard Linux file format so each disk is readable by any machine that can read the Reiserfs format. I seem to recall that was even a Reiserfs driver for Windows.) There are also companies that can often recover data from failed disks. (Warning, it is expensive...) But before I went too far down one of these recovery paths, I would first try to use the server to see what is left on those other seven data disks by using the 'New Configuration' Tool. ( @johnnie.black can probably point to instructions for doing this as I recall he has done so for others in the past.) (One thing I do know is if you get a prompt to reformat one of more disks, DON'T!!!) I personally would be copying off any of that critical data off before wasting time on a parity rebuild. Your loss may be less than you think at this point.

You should probably check you site settings in your browser. With Chrome, if you left-click on the /'lock' icon to the left of the URL, you will open up a dropdown box. You will find the site-setting button there.

Don't overlook the power connectors when checking...

I, personally, am not seeing anything to indicate that the 10TB disk is bad but something is definitely going on. I am hoping that @johnnie.black will see this 'Flag' and have a look to see what he thinks might be the issue.

I doubt if anyone can help you as the diagnostics file appears to have been taken after you replaced the 10TB drive. You might want to check on the Manufacturer's website as I understand that sometimes 'shucked' drives will qualify for replacement under warranty.

Personally, I am a firm believer that you should always have only a switch plugged into a router. Using inexpensive routers as a switch has two side issues. First, it causes the router to run hot and, second, it will usually have performances issues especially if you have fast Internet service. Right now, I can't understand why port2 is 'not working' unless the router is bad or misconfigured. (You do know that the ER-X is a prosumer router and is very powerful beast device but it has a bit of a learning curve. You can get the tutorial I was referring to here:) https://github.com/mjp66/Ubiquiti/blob/master/Ubiquiti Home Network.pdf

Do not format anything until one of the gurus says to do it!!!!

I don't have a direct answer to your question but I do have a suggestion for you. Google unraid.net cache pool and look at the threads found. I seem to recall that you can use an odd number of drives in a cache pool but I am not certain quite how to set it up.

What could it hurt at this point? If it did, I would be looking at the BIOS/MB battery...

It looks like you have a networking problem. The is no evidence that you are connected to anything from the diagnostics. Change Cat5 cable between server and router/switch. Do the lights on the router/switch and the server indicate that you have a good connection? Switch to a different port if connected directly to the router. Did you setup your ER-X correctly? (My ER-X was NOT a simple plug-and-play install! If you need help in this area, I can point you to an excellent tutorial for the beginner.)

So Sorry. Many drives do not report attribute 196-Reallocated_Event_Count and when I looked I was thinking it was attribute 197-Current_Pending_Sector. Attribute 196 reports an issue which has been fixed and Attribute 197 reports an issue which is going to be fixed in the future. At this point, I would continue to monitor this disk and to make sure that you don't get any changes in the future. (Btw, this disk has reached a temperature of 60C. This is a bit warm as most folks like to see the temperatures under 40C.)

I, personally, would replace it. While it will probably work and deliver up data, I would be worried about possible read-error issues on this disk if I have to rebuild another disk. After you get it out, you could run several preclear cycles on it and see if this was a fluke or a trend. It could also be that this disk is still in warranty... See next post....
