Description
sanity-pfl test_10 sets the default layout on $MOUNT and does not return the file system to the original state. For users running the Lustre test suites as a sanity check on their file systems, this is an unexpected side effect. We should return the file system to the state it was in before running sanity-pfl.
From sanity-pfl, the following code in test 10 sets the default layout:
$LFS setstripe -d $MOUNT || error "clear root layout" # set root composite layout $LFS setstripe -E 2M -c 1 -S 1M -E 16M -c2 -S 2M \ -E -1 -c 4 -S 4M $MOUNT || error "Set root layout failed"
Here's what the file system layout looks like before and after sanity-pfl test 10:
# lfs getstripe /lustre/scratch /lustre/scratch stripe_count: 1 stripe_size: 1048576 stripe_offset: -1 [root@eagle-48vm6 tests]# ./auster -k -v sanity-pfl --only 10 Started at Wed Apr 12 14:54:34 UTC 2017 … ./auster: completed with rc 0 [root@eagle-48vm6 tests]# lfs getstripe /lustre/scratch /lustre/scratch lcm_layout_gen: 0 lcm_entry_count: 3 lcme_id: N/A lcme_flags: 0 lcme_extent.e_start: 0 lcme_extent.e_end: 2097152 stripe_count: 1 stripe_size: 1048576 stripe_offset: -1 lcme_id: N/A lcme_flags: 0 lcme_extent.e_start: 2097152 lcme_extent.e_end: 16777216 stripe_count: 2 stripe_size: 2097152 stripe_offset: -1 lcme_id: N/A lcme_flags: 0 lcme_extent.e_start: 16777216 lcme_extent.e_end: EOF stripe_count: 4 stripe_size: 4194304 stripe_offset: -1
