Subject: xfstests and linux nfs testing

Was running into a strange error with xfstests over nfs - must be
missing something obvious since I have run it various times before.

Tried the following local.config file (placed in root of xfstests directory)

FSTYP=nfs
TEST_DEV=192.168.93.152:/share-1
TEST_DIR=/mnt/test
NFS_MOUNT_OPTIONS='-ov3'

and did
./check -nfs generic/001

which should have worked fine, but it and the various other nfs
capable xfstests returned

[not run] requires a test device

which is weird because even setting the TEST_DEV as an environment
variable xfstests still thought it wasn't set.

Anyone have a sample NFS local.config file for xfstests which works?

Thanks,

Steve

Sure! I'll fix up the patch so it doesn't have commented out lines while I'm at it :). I'll take a stab at server format validation, and then send something out!

Lukas broke this with:
common: Check fs consistency on TEST_DEV only when needed

as far as I can tell it blindly copied the _require_scratch code
to _require_test, which is bad for two reasons:

a) due to lots of code duplication
b) because it broke filesystems that don't support a scratch dev
like nfs.

Anna fix should work, can you resend it to the fstests lists with a
proper signoff? Even better would be some validation that the
passed in "device" is a valid format for a nfs export, but that's not
strictly required.

I think this is a bug in xfstests. This fixes it for me, but I'm not sure what needs to be checked in the NFS case:
