pras1011 Posted July 17, 2020 Share Posted July 17, 2020 (edited) I am using the server below and I will eventually be buying and preclearing 5 X 16tb Seagate Exos hdds. My current server uses Reiserfs and I want to migrate to XFS as I was told this is better filesystem. Basically I can do this two ways: 1) Do it on the old server below hdd by hdd one at a time. 2) Or build a new server with xfs and transfer data from old reiserfs server to the new xfs server. Which method is easier? Edited August 15, 2020 by pras1011 Quote Link to comment
JonathanM Posted July 17, 2020 Share Posted July 17, 2020 2 servers would probably be quicker. If the second server is easy to set up, that's what I would do, for several reasons. 1 Quote Link to comment
pras1011 Posted August 10, 2020 Author Share Posted August 10, 2020 (edited) Do I copy the usb drive of the old server minus the unraid key and then put that in the new server so that it can be exactly the same as the old server setup? If not, then what is the process? I only have one user share and I use the server for storing films for the zidoo media player. Edited August 10, 2020 by pras1011 Quote Link to comment
trurl Posted August 16, 2020 Share Posted August 16, 2020 Everything about your configuration is in the config folder on flash. Some things from that configuration that you will not want on the new server is the license .key from that other flash, since each flash must have its own unique key, and the super.dat file, which contains your disk assignments.

Hoopster Posted August 16, 2020 Share Posted August 16, 2020 Anyone?What are your plans for the old UnRAID server? If you won’t be using it for UnRAID, just use your current USB flash drive as is and do a New Config to get the new disks in the new server properly assigned and recognized.If the plan is to keep both in service, yes you can just copy the current flash drive, install a new license and do a new config.Sent from my iPhone using Tapatalk Quote Link to comment

pras1011 Posted August 16, 2020 Author Share Posted August 16, 2020 I will sell the old server once I have transferred the data over. So copy onto a new but temporary usb the contents of the current unraid usb and remove key and super file. Then plug it into new server. Both servers will be plugged into the same router and using a win 10 pc to do the transfer. The write speed will about 100MBps. That will take a while to transfer over 45TB. Both servers are 6 bay meaning I will only have on slot free on each server. If i move a reisfers disk to the new server, can i transfer internally at faster than 100MBps?

I assume that is either writing to cache, or no parity installed. Even so, I thought the scenario you were considering now was going from old server to pc to new server. You could go directly between servers and leave out the PC. Or just do one disk at a time directly on the new server with Unassigned Devices and leave the network out completely. You wouldn't even need the old server running and could just go with your already licensed flash drive on the new server. Quote Link to comment
pras1011 Posted August 17, 2020 Author Share Posted August 17, 2020 (edited) I have turned the faster write speed on, on the old server. I do not use a cache drive and the parity drive is active. And the pc is wirelessly connected to the WiFi 6 router. The old hdd are ironwolfs which are quite fast and the new hdds will be the exos. I am hoping that the speed will stay the same from old server to pc to new server. Sent from my SM-G977B using Tapatalk Edited August 23, 2020 by pras1011 Quote Link to comment
pras1011 Posted September 8, 2020 Author Share Posted September 8, 2020 (edited) I have my new WD Gold 18TB x 4 and currently running a parity check. When I finish do I move the permanent flash drive with pro key from the old server to the new server without any mods and remove the temporary usb?

New Config might be the best way instead of deleting config/super.dat, since New Config will let you Trust Parity. I'm not sure you get that option otherwise. If you had any VMs with passthru then expect those to need tweaking for the new hardware. Quote Link to comment
pras1011 Posted September 8, 2020 Author Share Posted September 8, 2020 So click New Config on the old server and then shutdown. Then put the permanent usb into the new server and redo disk config? Quote Link to comment

Boot up with the old flash on the new server. It won't let you start because none of the disks are the same. Do New Config on the new server, assign new disks, and check the box that says parity is already valid. Maker very sure you don't assign a data disk to the parity slot. Quote Link to comment
pras1011 Posted September 11, 2020 Author Share Posted September 11, 2020 (edited) 1) I have started the new server with the temporary usb but the share from my old server is not on the new server. Any ideas on this? 2) And its also started a Parity-Sync/Data-Rebuild on the new disks. Is this ok? 3) All of the data disks report that I have 126 GB USED. Is this ok?

Any ideas on this? The user shares are simply the top level folders on cache and array disks. The share name is the same as that top level folder name. Any disk that contains a top level folder named for a share contains files for that share. This is how user shares work, whether you create them in the webUI or not. Any share you haven't made settings for will have default settings. So, if there isn't a top level folder on cache or array for a share, the share doesn't exist. Have you started copying the share yet? 1 hour ago, pras1011 said: 2) And its also started a Parity-Sync/Data-Rebuild on the new disks. Is this ok? I assume its doing parity sync, which is what it has to do to build parity initially. 1 hour ago, pras1011 said: 3) All of the data disks report that I have 126 GB USED. Is this ok? Probably, XFS has some filesystem overhead, more for larger disks. Quote Link to comment
pras1011 Posted September 11, 2020 Author Share Posted September 11, 2020 1. I copied the share configuration file from the permanent usb to the temporary usb and rebooted the new server and then checked the share tab but nothing. (I am not using a cache drive) 2. Thought so. 3. OK but 126gb x 3 hdds is a lot! Quote Link to comment

Those top level folders I mentioned are what is required for a share to actually exist. Quote Link to comment

trurl Posted September 11, 2020 Share Posted September 11, 2020 Any top level folder on cache or array is automatically a user share, whether or not you actually created it as a user share in the webUI. In fact, people accidentally create user shares all the time by specifying a top level path somewhere, such as in docker mappings. And the user shares have the same names as those top level folders. If the top level folder exists on multiple disks, the share exists on multiple disks. Any user share you haven't configured has default settings, but since you copied the settings over, all you need is the actual top level folders themselves for the users shares to actually exist.

It is not so much that the user share is created. The user shares are just alternative views of the folders and files that have already been created. Quote Link to comment
trurl Posted September 11, 2020 Share Posted September 11, 2020 When you create a new user share in the webUI, Unraid creates a top level folder named for the share on cache or array as needed and in accordance with the settings for that user share. But whether or not the top level folder is created that way, or simply by specifying a path that causes a top level folder to be created, all top level folders are part of a user share with the same name as that top level folder.
