#2458 Backup fails with Unlock ioctl failed : Invalid argument


I am running Webmin 1.25 on a Sparc Ultra 10 with
Gentoo linux.

Whenever I try to run a filesystem backup, with either
dump or tar and seemingly regardless of any settings,
the backup fails as follows:

Performing backup of /etc to /backup/FrigateEtc ..

Unlock ioctl failed : Invalid argument

The filesystem being backed up is ext3, as is the
filesystem being backed up to.

The backup target is an NFS share, and my desktop, a
dual-processor Athlon-MP system also running Gentoo,
can backup to this directory using Webmin without any
problems. Same Webmin version.

    Does it help if you go to the Webmin Configuration module,
    click on File Locking, and select the Never Lock Files option?

    Alternately, you could try installing the IO::Pty Perl module.

    Failing that I am out of ideas, as this message really seems
    to be coming from the tar or dump commands..
