lvm utility in Ubuntu 14.04 LTS treats -l 100%FREE as a hard number
and not as an approximate upper limit. With ~5G scratch partition
and ~128M scsi_debug device, vg_108 is 1279+31=1310 extents long,
but only 31*2=62 can be allocated with -i 2:
# lvm lvcreate -i 2 -I 4m -l 100%FREE -n lv_108 vg_108
Insufficient suitable allocatable extents for logical volume lv_108: 1248 more required
lvm2 commit 4b6e3b5e5ea6 ("allocation: Allow approximate
allocation when specifying size in percent") made '-l 100%FREE'
possible when creating RAID LVs or setting number of stripes.
Fix it by setting the size to allocate to 100M, which is enough for
the test with 128M scsi_debug device.
[eguan: update commit log a bit to mention the lvm2 commit that
changed the lvcreate behavior]

_get_scsi_debug_dev is supposed to return a "/dev/$device".
However, in case the scsi device is not mapped to a disk, hence
/dev/sd* doesn't exist, then get_scsi_debug_dev would return only
the "/dev/" string. In generic/108 we check whether return value is
"" and only then consider it a failure. This behavior allows the
test to erroneously consider _get_scsi_debug_dev succeeded even if
it returned a malformed string. Fix this by correctly checking
whether the return value is "/dev/"

+ERROR: checking status of /dev/mapper/vg_081-base_081: No such file or directory
Ran: generic/081
Failures: generic/081
Failed 1 of 1 tests
Reason:
Command of "lvm lvcreate --yes" failed because lvm in RHEL 6.3
don't support '--yes' option.
Fix:
Use yes pipe instead '--yes' option for lvm, to make the command
support both new and old version of lvm.

Calls like fsync() should report failure on partial I/O failure, e.g. a
single failed disk in a raid 0 stripe.
This test is motivated by an XFS bug, and this commit fixed the issue
xfs: return errors from partial I/O failures to files
This case is written by David Jeffery <djeffery@redhat.com> originally.
