OMV crashes when copying between two CIFS shares

1st Official Post

    I'm running OMV 6.0.latest as a Proxmox VM. I'm finding that OMV crashes when I try to copy large files between two of its CIFS-mounted shares. The copy completes partially before the crash. I've tried having the shares mounted on two different systems, one OSX and one Ubuntu 23, but the problem is the same either way. The SMART status of the disks appears fine. I can copy files to and from individual CIFS shares to/from OSX, but cannot copy between the mounted shares.


    I'm not sure how to debug what's going on. Any advice?

    Thanks,

    Eric

    I just copied an 18GB file from one share directly to another share (just to make sure there wasn't some unknown recent error). The file has been copied without any problem, just as I expected.

    So I don't think OMV fails to execute this operation, it will probably be something in your network configuration, or in your virtual machine. I suggest you provide more information about your particular configuration so that someone can help you with this.

    Thanks for doing the test. I spent some time digging through the OMV log files, but didn't see any obvious smoking gun. (But, to be truthful, I didn't understand half of what was in there). Here are some details about my OMV network settings and the Proxmox OMV VM:


    Any suggestions on how to debug this would be greatly appreciated.

    Thanks,

    Eric

    You are welcome.

    Sorry but I've never virtualized on proxmox so I guess someone else can help.
