The readv/writev requests are queued inside smbd, but the number of outstanding io_uring requests are set by io_uring_queue_init(vfs_io_uring:num_entries,...). Can you try changing that value to see if the corruption point moves ? There is a...

Hello, Using Samba 4.12.1 with kernel 5.6.7 on Gentoo Linux, I wanted to test the new vfs_io_uring module. * Stand-alone Samba server acting as NAS for home setup. * /media/usb-backup is a mounted read-only btrfs filesystem. * Samba share exported as: ===== smb.conf ===== [global] ??? log level = 1 ??? workgroup = WORKGROUP ??? netbios name = NAS ??? server string = Samba Server ??? se...

Hello, I'm a bit desperate so I'm trying to seek help here. Many year ago, I built myself 2 file servers (5 disks enclosure for data, 2 disks enclosure for the OS) on a computer. It was running on Debian 7.11 for years without an issue and I was getting 75MB/95MB when transferring file from it to a Windows client, all having a 1gbs network card. https://i.ibb.co/N618Z4W/Debian-7.png

...e --------------------- The module makes use of the new io_uring infrastructure (intruduced in Linux 5.1), see https://lwn.net/Articles/776703/ Currently this implements SMB_VFS_{PREAD,PWRITE,FSYNC}_SEND/RECV and avoids the overhead of the userspace threadpool in the default vfs backend. See also vfs_io_uring(8). In order to build the module you need the liburing userspace library and its developement headers installed, see https://git.kernel.dk/cgit/liburing/ At runtime you'll need a Linux kernel with version 5.1 or higher.
