openstack:~/qemu-6.0.0-rc1/build$ sudo ./qemu-img check /mnt/esxi/name.vmdk
qemu-img: Could not open '/mnt/esxi/name.vmdk': Failed to lock byte 100: Input/output error
作为命令输出，qemu-img 5.2.91 无法检查 vmdk 文件，但 qemu-img 2.5 工作正常。
qemu-img 5.2.91 --help 得到这个：
Supported formats: blkdebug blklogwrites blkverify bochs cloop compress copy-on-read dmg file host_cdrom host_device luks nbd null-aio null-co nvme preallocate qcow qcow2 qed quorum raw rbd replication throttle vdi vhdx vmdk vpc vvfat
我该如何解决？谢谢
因为NFS目录下的vmdk文件，添加这个选项-o nolock修复了。
nolock — Disables file locking. This setting is occasionally required when connecting to older NFS servers. noexec — Prevents execution of binaries on mounted file systems. This is useful if the system is mounting a non-Linux file system via NFS containing incompatible binaries.
