• [ 6.6.0-rc4 ] NFS crashes

    • Solved Minor

    NFS consistently crashes with different shares and clients (MacOS and Ubuntu).  It seems I can make it crash very easily with Attached is the diagnostic report.  

     

    I'm a new user, and I'm in the process of migrating my data disks from BTRFS to XFS (encrypted) based upon feedback in the forums and my use case (mostly Plex).  I'm not sure that's the cause of the crash (this happened when i was all BTRFS as well), but I thought I should add that info

    I should add that when this happens, all of my shares (regardless of sharing protocol) disappear and I must reboot UNRAID to get them back again.

    I use NFS with ubuntu and also on unRAID between a Nextcloud VM and a share for data folder.  Only time I had a crash like what you describe is when removing a share or creating a share while also dorking with the share folder on the cache drive via telnet/ssh.  Ended up having to reboot to get SMB and NFS shares back.  If not doing that, how are you mounting the shares in ubuntu?

    Thanks for the reply.  I use autofs for Ubuntu to mount the exports.  The symptoms (NFS crash) also occurs with my Mac, so I'm not thinking this is a client issue.

    I think i'm having the same issue when i upgraded to 6.6 this week, and reverted to 6.5.3 since things kept disappearing with heavy NFS/disk activity. How do/where do I disable direct IO?

     

    Thanks,

    I started having this exact issue after upgrading to the 6.6.0 release. Once NFS went down all of my shares from the shares page disappeared. Rebooting the unraid server was the only way to get them back. It kept happening so I downgraded to 6.5.3 and have had no further issues with NFS.

    Marking this solved since no one has reported crash still occurs in 6.6.2/6.6.3.  If this same issue happens again, please open a new bug report.
