Hi Yu Jian,

would you mind trying this patch for 2.1 client http://review.whamcloud.com/6468 ?

Hi Bobi, please add the following test parameters into the commit message so that autotest can verify the patch automatically:

The above patch introduced an interop regression issue:

Lustre client: v2_1_6_RC2
Lustre server: 2.1.5

Hi yujian,

the log shows

got: objid=290 seq=0 parent=[0x2000013a0:0x1af04:0x0]

which reveals two things: the sanity test script contains this patch, ll_decode_filter_fid does not. New ll_decode_filter_fid is supposed to print something like got: "objid=290 seq=0 parent=[0x2000013a0:0x1af04:0x0] stripe=0"

The new interop regression is due to that 2.1.5 server does not contain the ll_decode_filter_fid.c change while the sanity test27z change (which 2.1.6 contains) needs couple with it.

[Jian Yu]

We have to add Lustre version check codes into sanity test 27z. The failure also occurs on the combination of 2.1.6 RC2 client with 2.3.0 server:
