[PATCH] xfstests: add support for ext4dev FSTYP

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Amir Goldstein <amir73il@xxxxxxxxxxxx>

blkid knows to identify the ext4dev FSTYP of a partition that was
formatted with mkfs.ext4dev.
quota tools and various util-linux utils are also aware of ext4dev,
so ext4dev shares the same capabilities as ext4.

While testing on Fedora 15, we encoutered a buggy fsck utility, which
invokes fsck.ext4, even though it was called with -t ext4dev argument.
In our setup fsck.ext4dev knows about new fs features that fsck.ext4
doesn't know, so the generic_fs_check fails.
Since we have no real use of the extra capabilities provided by fsck util,
we decided to invoke fsck.$FSTYP directly to avoid this issue.

ext4dev is used to test experimental ext4 code in mutual existance
with production ext4 code on the same system.

Specifically, ext4 snapshots code is available for testing as a
stand-alone ext4dev module for Fedora 15 and Ubuntu 11.4
(see http://next3.sf.net).
