    Replaced Failed Drive, Rebuilt Array, Rebuilt Drive Lost All Data

    in General Support

    Posted

    I did not submit a post I was proposing and I just received your latest regarding having the old disk 3.  I found it.  If necessary I could do what I have proposed below, but if I can recover the data from the old disk 3 that would be great.

     

    No, I formatted it in another machine to see if it would be usable again.  Dumb mistake made before I started this post.

     

    I explained what happened from memory and the list I keep telling me what physical hard drive are used as what share, what location they are in  on the PC  and the size of free space.  I do identify the share drives by brand, model, serial number, size and the date purchased.  I also keep track of the drives I remove so I have some record of what was replaced.   I concur that what you said about what happened to what disk is probably correct as I can not be sure of my memory.  Old age sometimes makes you forget more than you will ever know :-).

     

    The replaced hard drives were installed in a 5 in 3 device which did not result in the mucking around inside the computer which could have disrupted connections.

     

    Fortunately I have a list of all the videos I should have and from that,  I can try to find copies of the missing videos and I should have them on on-line backup.

     

    OK, I understand what you are saying and thanks for further understanding of how UNRaid works.  It looks like that data is lost then.  I will keep your explanation for further study if I have other problems in the future.

     

    What I plan on doing unless you think my plan won't work is this:

     

    I have 2 new spare 8 TB Drives and I presciently have (2) 8 TB parity drives.  I will remove all my drives, and reformat the parity drives on a different PC.  I will load the latest version on UNRain on a new flash drive.  I will then install one fresh 8 TB drive as a parity drive and the other 2 drives as data drives.  I will make them Plex drives and copy the files from the old 8 TB drives that have Plex data on them.  When those copies have been completed, I will format the old drives I copied from and install them.  I will then copy more data from the other hard drives and continue the process till I have moved all the data and reinstalled all the drives.  When I am finished with that, I will then use another 8 TB Drive for a 2ed parity drive. 

     

    When I install the new UNRaid usb stick, I will also upgrade it to allow more drives.

     

    Does this sound like a valid (although long process) path?

    I now know I need to update UNRaid to the current version.  I was unaware there were newer version till I tried to see what the problem was.  I did not want to update until this problem was solved so as not to increase the complexity of the situation.

     

    I also tried to resolve the issue myself because I have, on a previous occasion had a problem and the on line help (Not provider of the software) ended getting me into more problems and I had to start from scratch.  It appears that this group is much better at helping people that have problems and I appreciate that.

     

    The sequence of events as far as I can reconstruct them are as follows.  (In the future I plan on keeping better notes of what I did)

     

    I first replaced disk 7 which was a 4 TB drive with a 8 TB drive to give me more space for Plex.  That rebuild completed successfully, but about halfway through  the rebuild, UNRaid said disk 4 failed and needed to be replaced.  After disk 7 rebuild completed, All files seemed to be working except UNRaid still said disk 4 failed and needed to be replaced.  I installed a brand new 8 TB drive in the same slot that I took the failed disk 4 hard drive from.  When I tried to use it, UNRaid said I needed to format it.  Other times I replaced hard drives I did not have to format them.  I have in the past replaced over a dozen hard drives without having to format them or have any problems.  I formatted it.  Prior  to formatting the hard drive, as I remember, no available hard drive showed up as available for disk 4.  After reformatting the hard drive, the entry for disk 4 said missing, and the newly formatted drive was available.  I selected it and the rebuild completed.  Everything worked, all files were recovered and available.  Both of the rebuilds took a little over 3 days.  Several hours (Maybe 6 0r 8 ) latter, disk 3 failed according to UNRaid which said it was bad and needed to be replaced.  I replaced it as normal, except this time the rebuild took about 4 1/2 days.  When the rebuild was finished and available according to UNRaid, I noticed the hard drive was recognised with 8 TB of free space.  At this time I could not go down below the Plex directory from my desktop.  Using the command line on the UNRaid machine I could see the Disk 3 and the Plex folder, but nothing below it (such as movies or music folders).  All the other hard drives in the Plex share have the file structure  correct down to the actual files but I can not see anything in the Plex folder on my desktop machine or my laptop machine, both of which connect to the UNRaid machine via NFS.  I looked at the smart data and I believe all of the failed drives had excessive errors.

    I have included 5 copies of the logs.  The 20201018 log was today, the 20201012 log was done before I powered down when I saw that the replaced drive had not been restored properly.  The rest of the logs are (I believe) were created while I was solving the eirler drive replacement and rebuilds.  I included them in the event they may have some bearing on the problem.

    Short description of my problem – Had a hard drive failure, replaced and re-synced drives. UNRaid said re-sync completed successfully but new drive is empty.

     

    My Structure

     

    ~~~ Backups Plex Podcasts ~~~~

     

    Under Plex

    Movies

    Music

    TV Shows

    Other Folders

     

    Plex Uses Disks 1,2,3,6,7,9. All of which are now 8 TB Drives

     

    I can remotely access all files on UNRaid except for those under Plex

     

    My desktop system runs Linux Debian Buster and I connect to the UNRaid system via NFS connections.

     

    I am running UNRaid Vs 6.3.3.

     

     

    Back Story

     

    I replaced a 4 TB Drive with a 8 TB Drive.

     

    I did a re-sync successfully but during the re-sync, a 2ed 8 TB Drive Failed. I continued with the re-sync and when that was completed, I replaced the failed 8 TB Drive. I did another re-sync which completed successfully.

     

    About 8 hours later a 3ed drive (8 TB) failed. I replaced that with a new 8 TB Drive and re-synced it. Normally the re-syncs take a little over 3 days to complete. This re-sync took almost 5 days to complete. When it was completed, I had the message re-sync complete successfully . The problem was there was only one file on the drive of about 10 Gig.

     

    If I try to access anything from my desk top linux machine to the plex folder via the command line, the plex folder has nothing in it. I can access and go down to the file level on all the other top level folders.

     

    Opening the terminal on the UNRaid UNRaid machine, I can look all the folders and files in all the drives that are part of the Plex system except for the bassicly empty 8 TB drive. In addition I can play many of my videos via Plex except for a few which I suspect were on the replaced last 8 TB drive.

     

    As it stands now, I can not add videos to the Plex file system on the UNRaid machine and I can not see what videos I have. Of course I can go the UNRaid UNRaid machine and look at each hard drive to see what files are there via mntdisk1/Plex/. I also have a listing of the videos I did have before all these problems started, so if necessary, I can hopefully reload the missing videos., That is under the assumption I can remotely l drill down the file systems to the video level to add new videos.

     

    Any help recovering the missing videos and/or getting the file systems available from the remote system so I can manipulate the files would greatly be appreciated. I have attached a copy of the syslog.
