Please provide the following information
libtorrent version (or branch): libtorrent-rasterbar-2.0.9-r0 x86_64
platform/architecture: Alpine/amd64
application: Deluge running via Docker ( https://hub.docker.com/r/linuxserver/deluge )
compiler and compiler version:
Unsure
This seems like a similar issue to #6612 but with the plan9 filesystem using the virtio transport ( See https://www.kernel.org/doc/html/latest/filesystems/9p.html )
I've confirmed that this does not occur locally with ext4 or over NFS.

I tried seeing if there was any additional info supplied via pdbing Deluge and setting a breakpoint when it logs the error. Not much that I can see other than maybe the category code?
alert.error.message = "Invalid argument"
alert.error.value = 22
alert.error.category = 73
alert.what = "file_error"
output from mount:
storage on /mnt/storage type 9p (rw,relatime,sync,dirsync,access=client,posixacl,msize=512000,trans=virtio,_netdev)
I think I may just need to add the mount option cache=mmap but am not 100% sure if that's the right solution.
Seems to be working. Will close this out for now.
