[Qemu-devel] [PATCH] qemu-iotest: test 005, don't run on raw

[Feiran Zheng]

Patch on qemu-iotest.

005, test of creating 5TB images, not practical on raw format, so not run on it.

It's perfectly fine on raw, just try it.

Does this mean one must have that large fs space?

No.

But it says I can't create a 5000G raw image, this is the output of
`./check 005` (with qemu-img version 0.14.50)

IMGFMT        -- raw

Somewhat confusingly qemu-img converts any EFBIG return to this
message.  For some reason you have a really crappy filesystem that
doesn't allow 5TB files, I though that had died out long ago.

If I run it on XFS it works just fine.

I get it. I have ext3 so I can only have 2TB file.
Thank you.
