Qemu-img 5.2.91 can't open vmdk, Failed to lock byte 100: Input/output error, but qemu-img 2.5 work

Question

openstack:~/qemu-6.0.0-rc1/build$ qemu-img --version

qemu-img: Could not open '/mnt/esxi/name.vmdk': Failed to lock byte 100: Input/output error

As the command output, the qemu-img 5.2.91 can't check the vmdk file, but qemu-img 2.5 works fine.

qemu-img 5.2.91 --help get this:

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

How can I fix it? THX

Answer 1

Because the vmdk file in NFS directory, add this option -o nolock fixed it.

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.
