9p share troubleshooting

2 posts in this topic Last Reply

Recommended Posts

So, I have one 9p mount working correctly, and several not working. The one that is working is a drive mounted outside the array, all my array shares are not working. This Ubuntu VM is using a the virbr0 for connectivity. I get no mount errors, yet I can only see stuff on "encode" the rest stays blank. "encode" is mounted outside the array, formatted as XFS; all my shares in the array are also XFS. I'm also only seeing speeds of ~50MB/s from a "encode" to a samba share on the server.

 

XML:

    <filesystem type='mount' accessmode='passthrough'>
      <source dir='/mnt/disks/encode/'/>
      <target dir='encode'/>
      <alias name='fs0'/>
      <address type='pci' domain='0x0000' bus='0x02' slot='0x01' function='0x0'/>
    </filesystem>
    <filesystem type='mount' accessmode='passthrough'>
      <source dir='/mnt/user/Movies/'/>
      <target dir='movies'/>
      <alias name='fs1'/>
      <address type='pci' domain='0x0000' bus='0x02' slot='0x02' function='0x0'/>
    </filesystem>
    <filesystem type='mount' accessmode='passthrough'>
      <source dir='/mnt/user/Anime/'/>
      <target dir='anime'/>
      <alias name='fs2'/>
      <address type='pci' domain='0x0000' bus='0x02' slot='0x03' function='0x0'/>
    </filesystem>
    <filesystem type='mount' accessmode='passthrough'>
      <source dir='/mnt/user/TV/'/>
      <target dir='tv'/>
      <alias name='fs3'/>
      <address type='pci' domain='0x0000' bus='0x02' slot='0x04' function='0x0'/>
    </filesystem>
    <filesystem type='mount' accessmode='passthrough'>
      <source dir='/mnt/user/Anime-AniDB/'/>
      <target dir='anime-anidb'/>
      <alias name='fs4'/>
      <address type='pci' domain='0x0000' bus='0x02' slot='0x05' function='0x0'/>
    </filesystem>
    <filesystem type='mount' accessmode='passthrough'>
      <source dir='/mnt/user/New Media/'/>
      <target dir='newmedia'/>
      <alias name='fs5'/>
      <address type='pci' domain='0x0000' bus='0x02' slot='0x06' function='0x0'/>
    </filesystem>

Sorry for necroing the post, but did you ever manage to get this working? I had problems with 9p as well, but I can mount everything, but I just can't create new files into the shared folders. But I can edit, rename and delete existing files and folders (?!). While some other mount shares (with the exact same permissions and setup) working without problems. I had better luck with mounting shares from the array itself, and not the unassigned ones. Now I suddenly struggle a bit with a cache drive, while the regular "user" share works as expected.

With one of my VM's I just ended up using NFS, at least it works, but it seems to be limited to 1Gbps which is not ideal for an nvme device. Maybe I should open a virtual network as well and not just passing it through. But 9p would been nice to use and simple in theory.. if it would work as expected.
