Description
sanity test_300g fails with the following lines from the test_log output
== sanity test 300g: check default striped directory for normal directory ============================ 17:47:37 (1504806457) CMD: onyx-40vm7 /usr/sbin/lctl get_param -n version 2>/dev/null || /usr/sbin/lctl lustre_build_version 2>/dev/null || /usr/sbin/lctl --version 2>/dev/null | cut -d' ' -f2 error on LL_IOC_LMV_SETSTRIPE '/mnt/lustre/d300g.sanity/striped_dir/dir2' (3): No such device /usr/bin/lfs setdirstripe: cannot create stripe dir '/mnt/lustre/d300g.sanity/striped_dir/dir2': No such device sanity test_300g: @@@@@@ FAIL: create dir2 fails
The problem is in the test at
15297 $LFS setdirstripe -i2 $DIR/$tdir/striped_dir/dir2 || 15298 error "create dir2 fails" 15299 stripe_index=$($LFS getdirstripe -i $DIR/$tdir/striped_dir/dir2) 15300 [ $stripe_index -eq 2 ] || 15301 error "dir2 expect 2 got $stripe_index"
The test checks that there are at least two MDTs (we need to stop using MDSCOUNT as MDTCOUNT, but that’s for a different ticket) and then creates two directories with ‘lfs setdirstripe –iN …’, with N = 1 and 2, striping directories at MDT index 1 and MDT index 2.
The problem here is that, with only two MDTs, creating a directory that starts with MDT index 1 works as expected, but creating a directory that starts at index 2 fails because MDT indexes are zero based and we only have two MDTs with indexes 0 and 1.
This test has passed review-dne-part-* testing because typical DNE testing creates two MDSs with two MDTs each and a MDT starting index of 2 is valid.
There are at least two ways to fix this issue; make sure you have three or more MDTs for this test or just create directories that have starting index 0 and 1.
