[LU-6198] large-lun test_1, test_2 defects: lustre format is not restored

Tue, 17 May 2016 15:09:52 +0000

setupall()->start ost called at the end of large-lun.sh
fails to start the ost devices which leads test_1() and
test_2() fail if run separately.
The reasons are:
1) osts data are destroyed by test_1()->llverdev
2) osts are reformatted by test_2, but mds config not changed

To reproduce:

# sh llmount.sh
# ONLY=1 sh large-lun.sh

xtrace:

+ true
+ setupall
...
+ start ost1 /dev/vdb -o user_xattr
...
+ /usr/bin/pdsh -R ssh -S -w fre806 '(PATH=$PATH:/usr/lib64/lustre/utils:/usr/lib64/lustre/tests:/sbin:/usr/sbin; cd /usr/lib64/lustre/tests; LUSTRE="/usr/lib64/lustre" sh -c "mkdir -p /mnt/ost1; mount -t lustre -o user_xattr                                  /dev/vdb /mnt/ost1")'
+ sed 's/^fre806: //'
