  1. Hello Harro, I, too, thank everyone who took the time to read and respond to my questions and requests for help because, it turns out that, no more than a few hours after you asked a question about doing a disk conversion from RFS to XFS, I asked a very similar one. I also used Unbalance to empty a disk and then re-Format the empty disk. I then used Unbalance to move the next set of files and so on. I am doing my third disk now. For me, it also appears to have worked seamlessly and with my array serving files the whole time except for just a few minutes. I am using Unraid 6.3.2 But this was after I did follow the file conversion wiki to do my first conversion. To those who will know, I would ask why the wiki outlines, what seems to be, such a convoluted system of swapping drive assignments and new configurations while over-riding un-needed parity re-builds. At the same time, still very strongly cautioning about background processes that might be changing the files. It's fairly nerve-wracking for a newbie. 19 Steps is a daunting total. Can I assume it is because my array is very simple? It is just a home media file server. One user share and no disk shares. No dockers or any other programs running. No cache drives and just one parity disk. In essence, I don't care where the actual files are located, I just need Unraid to keep track of the 1 user share. If I had a more complex system, could I have brought the whole thing down by doing what I've done? Is that why keeping the files in the same disk location so important? Not wishing to be a bother but just interested to learn.
  2. Hello, I'm using a KVM switch to share my peripherals with my PC. I can't copy and paste through that. I was used to doing it that way for a long time in the past with other PC's long before the remote desktop connection became a part of windows. I have only just started reading up about Putty and should probably retire the KVM and move ahead a couple of years in technology but the old man in me is a bit hesitant. A question, please. If I open a putty session and start something in that console, will it keep running if I log out or close the window? Do I need to keep a putty window open until the task is complete? I kind of like the KVM because it is 2 button presses and I'm straight in and watching whatever is happening and it just keeps happening when I button out.
  3. With the help of some community members here, and the instructions in the wiki that are based on this thread, I have completed the addition of a new drive, and replaced a RFS drive with an XFS drive. I now have a drive excluded from the global shares as per the instructions. At this point I could repeat this process as per the wiki for the remaining disks using the rsync command and the disk swaping of assignments etc. However, is it possible for me to complete the transfer of the rest of the drives in this fashion: 1) Stop the array and put the excluded drive back into the global shares 2) Start the array - Will a parity check occur at this point? the drive was already included in the parity calculations even if it wasn't part of the user share, correct? 3) Use the Unbalance plugin to shift all the files from one of the RFS disks to the newly included and empty XFS disk. 4) Stop the array and change the file system on the newly emptied disk from RFS to XFS 5) Start the array and then format the drive. Will parity be maintained by the copying method used by Unbalance? I'm hoping that this will then present me with another XFS formatted drive which is included in the array and I just proceed until all drives are done. Any help with this is again appreciated.
  4. Thanks for your help and input. Yes, it was the rsync commands that I found difficult to interpret. I find it hard to determine if the / has a space before or after it or if there is no spaces at all. I was already a little sensitized to this issue because of an issue I am/was having with preclearing some drives. In this post https://forums.lime-technology.com/topic/12391-re-preclear_disksh-a-new-utility-to-burn-in-and-pre-clear-disks-for-quick-add/?do=findComment&comment=506407 some corrections to the preclear_disk.sh file are presented. I really struggled with getting the second more complex correction done and had to give up. I will write a post to this topic talking about all the issues I have recently had with a preclear that would not go correctly. The other information you shared has made me think of something. I'm not sure if this is the right place to bring this up. It would seem to me that it is possible to have a second set of drives which are not a part of the user shares and could then act as backups to the drives in the array. The drives in the array could be public for use by anyone on the network, and the others could be secure and controlled by an administrator. Although not a true, offsite independent backup, they would be a set of redundantly protected backup disks holding copies of files. Is this actually acheivable? Does anyone do this?
  5. Thanks for your help. I have just finished the first drive re-assignment and it all went well. I will now finish the rest but it will take quite a while. It seems to me that the good part about this process is that the array is protected for most of the time, and I will only need to do a rebuild parity at the end of all the re-formats if I choose to shrink the array again. I might do this because there was one drive that was starting to play up and occasionally produced a few read errors.
  6. Hello all, Apologies if this has already been covered in this thread but I haven't been able to find the answer to my circumstances in my reading here. I am running Unraid plus 6.3.2. and wanting to do this conversion as part of a major array overhaul. I have followed the instructions to do the file system changeover from the wiki page, which links back to this thread. As a part of the instructions, it says to exclude the new swap drive in the global share settings before starting the array. I did this and then started the rsync command in the console. I saw all the files begin to get copied and the varying rates at which the copies occi\urred. So far, so good, and no problems. However, when I went back to the Unraid GUI in Windows, I noticed some things that concerned me. These are: 1) The swap disk seems to be included in the array. Its capacity was added to the capacity of the array after it was assigned and formatted. 2) The Shares tab now has a Disk Share for the swap disk that I didn't specifically create. 3) The Users Share (i only have one share) still shows included disks as 'all' and no disks as excluded 4) Both the new swap disk and the parity disk are doing writes as the copying is progressing. I assume this is slowing down the copy process. 4) The total capacity of the drives is being reduced by the size of the files as they are being copied. Is this normal behaviour? When it says to exclude the drive, I assumed that it would be reflected in these array markers. My main question is, is it safe to continue the process as documented? As just a minor issue/suggestion, some of the written command lines (where the criticality of not making and error are highlighted) can be difficult to read when it comes to the spacing. Sometimes it loks like the command is just one long string but spaces in the string exist, and at other times there appear to be spaces but in fact it is a continuous string. As a very much newcomer to this command line writing, so way to indicate spaces would be helpful and appreciated.
  7. I disabled the onboard NIC and used a PCI NIC. Instant return to usable read speeds. See attached NAStester jpg. I can't say if the fault was a coincindence with the install of 6.1.9 or related. I did not try (and would prefer not to try) a return to 5.05. I am now moving forward with the original base issue of re-encoding/reloading etc. 1.68 TB of cryptolocker corrupted files.
  8. RobJ, OK, understand better now. Will do. Sorry for any confusion.
  9. Hello itimpi, Thanks for your input. The diagnostics file is attached now. any help appreciated tower-diagnostics-20160605-1651.zip
  10. Hello All, I may be having a similar problem. I was in the process of upgrading from v5.05 to 6.1.9. I was doing this because I had lost my USB key files to a cryptolocker attack and all the files on the flash drive were encrypted. I re-formatted the USB, loaded 6.1.9 and got a successful boot and re-assigned all my drives and did a new permission run, then did a parity check. All good to this point. The parity check took no longer than normal (16 hours). I started adding plugins etc. and was serving media files to my network which is the main use of my unraid server. Again all good to this point. I then noticed that a higher than usual definition file was stuttering on playback to my media player. I then saw that the network speed to the media player was about a 1/10th of usual/previous. After much troubleshooting with wireless and wired connection to the player, I noticed that the read rate from the unraid server was very low. I have attached the output of a cute program called NASTester which records the read and write performance of a network. My U drive is in a ubuntu server and V drive is the Unraid server, both are wired connections to the same netwrk that my windows machine is wired to. It is a Netgear D6200 gigabit router and they all have gigabit NI on motherboard. As you can see the read/write on the ubuntu server is fine and the write to Unraid is fine but the read rate is 0.6MB/s. I tried a fresh re-install of the 6.1.9 unraid, in case I ruined the plugin settings etc. and did it to myself but the read speed was unchanged even without any plugins added. Again the parity check proceeded at an excellent rate. I don't know if the slow read is directly related to 6.1.9 and hardware problems in my setup, because I have a vague recollection of copying 1 subdirectory from the server to the ubuntu machine and getting good speed doing so, while I was troubleshooting what I thought was a configuration issue on my media player. However, i may have copied it from a backup disk on the ubuntu machine to the shared folder on the ubuntu machine. I can't remember exactly where it came from. I hope this isn't too confusing. My main question is this, if i haven't changed anything on the data drives for unraid, can I go back to 5.05 safely? I can't use the previous setup and will need to do a fresh install. Will this be OK? Otherwise, I'm going to disable the onbaord NIC and install a PCI card and see if that helps. I have been using unraid for several years and am so happy with it. Thanks in advance for any thoughts or feedback.
  11. The upgrade to V6 went flawlessly. Although my V5 USB files, including my key file, were all encrypted, i was able to upgrade using the key file from my V4.7 backup of the USB key. I just re-assigned the drives after boot and was running within a few minutes. I have set myself as the only user with read/write priviledges. Guests (everyone else) are read only. Thanks for all your help, folks. I now have the task of deleting all the encrypted files and trying to find/re-backup/re-encode replacements. As a point of interest, the cryptolocker was only active for about 20 minutes from my wife's laptop to the Unraid server which was mapped as a drive to her machine for ease of her access. I had not restricted guests (including my wife) to read only. In that 20 minutes, 3338 files to a total of 1.68TB were encrypted. I can't imagine that in that 20 minutes it read into memory across the network all those files in their entireity, encrypted them and copied them back onto the server. It must just encrypt enough of the file to make it unusable. A simple rename doesn't do it, of course.
  12. Thanks for your response. Let me get this correct. I have a copy of my plus.key file on my original 4.xx flash drive backup. I record all the drive assignments. Cross fingers. Shutdown the server. I reformat the corrupt flash drive. I make bootable and extract files etc. Boot up reassign drives See working array Uncross fingers. Drive was mapped to allow my wife easy access to the files. I now know to create a user for her and give read only access. Horse bolted - barn door etc. If it all comes to nought, is there any way to pull the unencrypted files off the drives outside the case? Thanks again.
  13. Hello All, Well, disaster here. My wife's laptop had cryptolocker opened onto it and has done terrible damage. My Unraid tower was a mapped drive on the laptop and crytolocker encrypted many, many files on the server. This included most of the files on the flash drive with all the configuration of the server. The server is still operating but I am extremely worried as to what might happen if the tower is powered down. I am sure it won't boot up again. For example, Unmenu no longer works but the default GUI still does. I have a copy of the flash key files when I upgraded to 5.05 from 4.xx about 2 years ago but nothng more recent. I have added and changed several hard drives since that upgrade. Does anyone have some thoughts on how to move forwrd from this? I am not talking about trying to rescue or decrypt the individual files. The overwhelming information is that it is impossible without the key from the ransomers. I have about 8TB of data of which 1.8TB is encrypted. But this does include just about everything on the flash drive, as I have mentioned. If I reformat the flash key and reinstall 5.05, will it recognise the array? Is this a first step? If that fails, and I then need to remove the discs, how easy is it to move the data off those discs? Will my windows PC read the drives from an external USB box? I would welcome anyone's thoughts on how they would move forward. Thanks in advance for your help
