I have a crazy idea that I want to do.... I have both a IBM M1015 and M5015. The M1015 is in IT Mode (JBOD) and is running in my 24Bay SuperMicro 4U Chassis (SAS Backplane) Connected with a single SFF-8087 Cable HDDs Installed 12 1TB SAS 7.2k 4 600GB SAS 10k 4 450GB SAS 15k 2 500GB SATA 1 600GB SATA 1 3TB SATA Now, I only have about 6TB of storage in use. But if I can avoid transferring data around, I would like to. I would like to put my M5015 back into good use and MAYBE do a silly hybrid RAID unRaid system. Now, my M5015 cannot do JBOD mode at all. I'm thinking of setting up 3TB Max RAID0 or 5 v-disks. Make the system a little bit quicker with some heavy hitting issues. Would also like to get MEGA-Raid working though it as well, but I've read that is quite hard to setup in Slackware. I do so that I have use the MEGA-Raid interface for predictive failure analysis. Which I currentrly cannot get working. Am I crazy?

Well, I got the tool installed but when i try to run it, I get this: -bash: /usr/bin/screen: cannot execute binary file: Exec format error

Now... how do we tag this as solved?

Wow... it's funny how I got case inconsistencies from the GUI and console. You guys were correct. Thank you!

I got a used powerconnect switch but I cannot access the webGui on it. So, I'm trying to console into it via serial port and my unRaid box is the only thing i have with a serial port. And I do not have a serial port emulator. Screen appears to be missing from the base OS. Any idea how install it? I've never touched slackware. Always been a DEB guy....

SOLVED Trying to hone my Linux-Fu and run my plex server on a separate machine. It is running Linux Mint 18.2. I have exported and setup my NFS Shares on unRaid properly but I'm running into the following issues when running "mount -a". NOTE: Doing a straight mount command from bash works properly. I would love to get this to automount during a reboot. I know that I also have to wait for the network to become "active" before letting it try to mount. Not sure how to do that! /etc/fstab Front Linux Server: unRaid Log:

Did not know that at all. THANK YOU

I keep getting this problem with port 53 for the DNS server. I'm unsure how to correct it...

I have a disk that shows that it has failed with a read error. Smart Data shows that the disk is just fine.... What do I do? I've read the documentation for my major version (6.2.4) and it does not describe in good detail what I do in this kind of situation.

Disk 9 was excluded from all user shares. It was a SSD that I desperately needed to repurpose into something else. I would of just ran and got a SSD from Best Buy or something but for some odd reason, they were cleaned out of all SSD's except for the 1TB(ish) ones. I was doing the transfer via CIFS and I know this practically cuts the available bandwidth in half. I'm not using Jumbo Frames or anything fancy. And it was a single large file. It was a vDisk for a VM that needed to be moved off. Yes, the VM was powered off. Also, it was a Copy and Paste, not a cut and paste. I eventually stopped it and ran Dolphin and copied the file that way. Then it went as fast as the hard drive could write. FYI - I have acquired a new SSD and dropped it in. It is running as a cache device formatted with BTRFS. The rest of the drives are running XFS which I'm in the process of changing to BTRFS... One by One... And transfers and now speedy via CIFS.

While i have not been getting this exact error, I'm seeing quite a bit of "Silent corruption" that I monitor with a checksum addon. Just wait for it to finish and it will create a Lost+Found folder. I'm actually in the process of changing over to BTRFS, though ZFS would of been a nice addition.

Can anyone explain to me why Unraid is doing this? I'm in version 6.1.9 I'm doing a copy and paste of a drive that is going to be removed. This disk is not part of any share. It is called Disk9. I'm copying all the info into a user share though. Also, it nearly consumes my entire RAM with cached info when it is not even doing anything.

I'm smoked if I don't have a backup of my NAS, correct?

I think it would be grand if you could set aside some of the cache pool as a read cache. This would allow me to truly use unraid to store all my steam games. They KEY here is that i would not have to move the games around. It will see a trend of what I'm getting on a regular basis and start to store that in the read cache for faster access.

Hey everyone... did something stupid. I have all my disks set to XFS but I want to change to BTRFS to see if I get any performance Improvements. Here is what I did: Turned off the array Selected disk 1 Changed to BTRFS Started array formatted Did not see a rebuild option anywhere *Face Palm* . *PANIC!* Turn off array change it back to XFS Start in Maint. Mode. SSH into unraid ran this: xfs_repair -v /dev/md1 right now i'm waiting for it to complete. It was not able to find the primary superblock and it searching for a secondary. What Should I do at this time. The format did not take enough time to really remove any data on the drive other than probably the partition table data.

I recently and suddenly lost the ability to RDP onto my 2008r2 server. Other services like PLEX do work. I have my firewall turned off on the server (yes, it is off) but it cannot seem to open a port at all. There is no AV on this server either. I'm plum confused as to why this server will not accept an RDP connection. I have tired other ports other than 3389 and get the same result. and it has been turned off and turned on again. For kicks and grins, I tested with telnet and the port number and it fails the connection immediately.

This is only half true. A SSD will provide MUCH better latency and be able to fill a 1Gb pipe while with small files (which games a ton of). Now, I don't have 300GB, 15k SAS drives, so I really doubt my consumer drives are going deliver SSD Performance with small file reads...

The unraid cache drive does not work in the way you think it does. It sits in between the write process. A file beiing written is actually written to the cache drive and written back to the array nightly.. It does no write caching at all.. Second function of the cache drive is to keep files indefinitely (mostly not media files, but additions to the unraid system, dockers, plugins, etc). Nope, that is how I understand the unRaid cache drive. I was hoping there was a way for it to cache commonly read items as well. IMHO, this would negate alot of die hard raid users to switch to unraid. In my post before this, I stumbled upon a way to using my machines local SSD to cache network shares for faster reads.

The Non-Ultra ones are rated good. They have not rated these ones which are only 2nd the extreme pro sticks.

I have found a solution to what I was looking for. The only thing I was looking to cache are Games. I only have a 256GB in my main rig but with games going 40+ gigs in size, that can fill up fast. So I just mapped a Games drive and called it a day. Then I though about going to lan parties and such and not having the fastest access to the network drive (connect via VPN). So, I would turn on Windows Offline Files and point it to my G Drive. Then, I noticed (after a full sync) reads where bitchin fast again... I did not fully understand the mechanics behind this feature so I found this: https://helgeklein.com/blog/2012/04/windows-7-offline-files-survival-guide/ HELL YES! I stumbled upon my own solution. It even see what is used most and caches against that!

Problem turned out to be that my original download of unraid got slightly corrupted. I also clean up my share mappings so that they make a but more sense. TY For the help!

Sorry for just now getting back to this. I examined the files on the flash drive and there were quite a few files that had nothing in them what so ever. So, I decided to blow the drive away and re-write it. Same Result Downloaded unRaid again Try again Boom - SSH Keys and there is more actually data on the flash drive. My guess is that I had a bad download.

I'm having an issue to where I wake up in the morning and discover that the unraid shares are not functional. It does not share as if the pool is offline though. Going to the Shares Tab locks the webGUI up. All dockers go offline because it cannot find the shares. From the syslog, it appears the mover still works though which seems odd to me. I have attached the full diagnostics ZIP. Can anyone let me know what is going on? I cannot seems to figure this out and i'm going on 3 days like this already... and the wife is getting really upset! tower-diagnostics-20160131-0949.zip

Let me start, I'm not a newb to Linux but I am no means proficent from a professional standpoint. Now, with EVERY other linux or BSD based setup I have used in the past, SSH is ethier already installed or I have to install the package. It appears that SSH is already installed. After that, I just have to start a connection via 22, accept the RSA Keypair, enter username and password, boom, I'm in. I cannot even get to the RSA Key section. Now I did read somewhere that I have to generate it then put it on the USB Stick manually. But i cannot find this info no matter how much I search. So, how do we set this up?
